STARS provides rapid and specialized emergency care and transportation for critically ill and injured patients. STARS operates from bases in Calgary , Edmonton , Grande Prairie , Regina , Saskatoon , Winnipeg and formerly Halifax (replaced by EHS LifeFlight ). STARS
320-610: A runway . In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production . Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter , not to be confused with the single-blade monocopter ) has become the most common helicopter configuration. However, twin-rotor helicopters (bicopters), in either tandem or transverse rotors configurations, are sometimes in use due to their greater payload capacity than
480-503: A satellite campus of the University of Alberta . The 1970s energy crisis resulted in significant investment and growth in Calgary. By 1981, 45 percent of the Calgary labour force was made up of management, administrative or clerical staff, above the national average of 35 percent. Calgary's population grew with the opportunity the oil boom brought. The 20-year period from 1966 to 1986 saw

Following the fire several quarries were opened around the city by prominent local businessmen including Thomas Edworthy, Wesley Fletcher Orr , J. G. McCallum, and William Oliver. Prominent buildings built with sandstone following the fire include Knox Presbyterian Church (1887), Imperial Bank Building (1887), Calgary City Hall (1911), and Calgary Courthouse No. 2 (1914). In February 1887, Donald Watson Davis , who

A swashplate controls the collective and cyclic pitch of the main blades. The swashplate moves up and down, along the main shaft, to change the pitch of both blades. This causes the helicopter to push air downward or upward, depending on the angle of attack . The swashplate can also change its angle to move
1120-417: A constant altitude. The pedals serve the same function in both a helicopter and a fixed-wing aircraft, to maintain balanced flight. This is done by applying a pedal input in whichever direction is necessary to center the ball in the turn and bank indicator . Due to the operating characteristics of the helicopter—its ability to take off and land vertically, and to hover for extended periods of time, as well as

In 1861, the word "helicopter" was coined by Gustave de Ponton d'Amécourt , a French inventor who demonstrated a small steam-powered model. While celebrated as an innovative use of a new metal, aluminum, the model never lifted off the ground. D'Amecourt's linguistic contribution would survive to eventually describe
2080-405: A helicopter determines the size, function and capability of that helicopter design. The earliest helicopter engines were simple mechanical devices, such as rubber bands or spindles, which relegated the size of helicopters to toys and small models. For a half century before the first airplane flight, steam engines were used to forward the development of the understanding of helicopter aerodynamics, but
2240-504: A helicopter powered by a gasoline engine with box kites attached to a mast by cables for a rotor, but it never flew. In 1906, two French brothers, Jacques and Louis Breguet , began experimenting with airfoils for helicopters. In 1907, those experiments resulted in the Gyroplane No.1 , possibly as the earliest known example of a quadcopter. Although there is some uncertainty about the date, sometime between 14 August and 29 September 1907,
2400-416: A helicopter. This is because a helicopter generates its own gusty air while in a hover, which acts against the fuselage and flight control surfaces. The result is constant control inputs and corrections by the pilot to keep the helicopter where it is required to be. Despite the complexity of the task, the control inputs in a hover are simple. The cyclic is used to eliminate drift in the horizontal plane, that
2560-509: A larger medical interior, more powerful lift capacity, and a de-icing system that will enable flight during adverse weather conditions. The first of the two AW139 helicopters is now operating in Edmonton, while the second is operating in Calgary. A third AW139 , purchased through the support of Potash Corporation , is deployed to the Saskatoon base. The STARS Air Medical crew (AMC) consists of
2720-533: A minimum of 3,000 hours flying experience and are trained to fly with night vision goggles. The helicopters also have powerful search lights and can participate in search and rescue missions when tasked. The first STARS base opened in Calgary in 1985 under the original name of the Lions Air Ambulance Service. The Lions Club provided the first helicopter, a white BK117 with the Lions Club banner on

Calgary elected its MLAs through PR until 1956 and its councillors through PR until 1971 (although mostly using instant-runoff voting , not STV, in the 1960s). Calgary endured a six-year recession following the First World War . The high unemployment rate from reduced manufacturing demand, compounded with servicemen returning from Europe needing work, created economic and social unrest. By 1921, over 2,000 men (representing 11 percent of

The 4th-century AD Daoist book Baopuzi by Ge Hong ( 抱朴子 "Master who Embraces Simplicity") reportedly describes some of the ideas inherent to rotary wing aircraft. Designs similar to the Chinese helicopter toy appeared in some Renaissance paintings and other works. In the 18th and early 19th centuries Western scientists developed flying machines based on
3840-441: A single main rotor, but torque created by its aerodynamic drag must be countered by an opposed torque. The design that Igor Sikorsky settled on for his VS-300 was a smaller tail rotor. The tail rotor pushes or pulls against the tail to counter the torque effect, and this has become the most common configuration for helicopter design, usually at the end of a tail boom . Some helicopters use other anti-torque controls instead of
4000-417: A state called translational lift which provides extra lift without increasing power. This state, most typically, occurs when the airspeed reaches approximately 16–24 knots (30–44 km/h; 18–28 mph), and may be necessary for a helicopter to obtain flight. In forward flight a helicopter's flight controls behave more like those of a fixed-wing aircraft. Applying forward pressure on the cyclic will cause

By contrast the autogyro (or gyroplane) and gyrodyne have a free-spinning rotor for all or part of the flight envelope, relying on a separate thrust system to propel the craft forwards, so that the airflow sets the rotor spinning to provide lift. The compound helicopter also has a separate thrust system, but continues to supply power to

By October 2018,
11680-673: The NWT Lieutenant-governor, organized a public meeting in the NWMP barracks room on the issue of getting a representative in the NWT Council. Walker wrote the clerk of the Council that he was prepared to produce evidence that Calgary and environs (an area of 1000 square miles) held 1000 residents, the requirement for having a Council member. A by-election was held on June 28, 1884, where James Davidson Geddes defeated James Kidd Oswald to become
11840-554: The Nakoda or Stoney language , the area is known as Wîchîspa Oyade or Wenchi Ispase , both meaning "elbow". In the Cree language , the area is known as otôskwanihk ( ᐅᑑᐢᑿᓂᕽ ) meaning "at the elbow" or otôskwunee meaning "elbow". In the Tsuutʼina language (Sarcee), the area is known as Guts’ists’i (older orthography, Kootsisáw ) meaning "elbow". In Kutenai language ,
12000-641: The National Energy Program marked the end of Calgary's boom. In 1983 Calgary City Council announced service cuts to ease the $ 16 million deficit, 421 city employees were laid off, unemployment increased from 5 to 11 percent between November 1981 and November 1982, eventually peaking at 14.9 percent in March 1983. The decline was so swift that the city's population decreased for the first time in history from April 1982 to April 1983, and 3,331 homes were foreclosed by financial institutions in 1983. Low oil prices in
12160-518: The Niitsitapi (Blackfoot Confederacy; Siksika , Kainai , Piikani ), îyârhe Nakoda , Tsuutʼina peoples and Métis Nation, Region 3. In 1787, David Thompson , a 17-year-old cartographer with the Hudson's Bay Company (HBC), spent the winter with a band of Piikani Nation encamped along the Bow River. He was also a fur trader and surveyor and the first recorded European to visit the area. John Glenn
12320-487: The North-West Territories , who happened to be in Calgary at the time, to discuss an allowance for a school, an increase from $ 300 to $ 1,000 grant for a bridge over the Elbow River, incorporation as a town, and representation for Calgary in the Legislative Council of the North-West Territories . The committee was successful in getting an additional $ 200 for the bridge, In May, Major Walker, acting on instructions from
12480-590: The Swedish community of Falun and Italian community of Cortina d'Ampezzo . On September 30, 1981, the International Olympic Committee voted to give Calgary the right to host the 1988 Olympic Winter Games , becoming the first Canadian host for the winter games. The Games' five primary venues were all purpose-built, however, at significant cost. The Olympic Saddledome was the primary venue for ice hockey and figure skating. Located at Stampede Park ,
12640-627: The Winnipeg site. In Manitoba , STARS is dispatched from the provincial Medical Transportation Coordination Center (MTCC) in Brandon , MB. The MTCC is the EMS dispatch center for rural Manitoba outside of the City of Winnipeg. STARS managed the air ambulance service in Nova Scotia from 1996 until 2001, when their contract was not renewed. Then Health Minister Jamie Muir , cited "fundamental differences" regarding
12800-550: The aircraft's handling properties under low airspeed conditions—it has proved advantageous to conduct tasks that were previously not possible with other aircraft, or were time- or work-intensive to accomplish on the ground. Today, helicopter uses include transportation of people and cargo, military uses, construction, firefighting, search and rescue , tourism , medical transport, law enforcement, agriculture, news and media , and aerial observation , among others. A helicopter used to carry loads connected to long cables or slings
12960-470: The area was named after the reeds that grew along the riverbanks, reeds that had been used to fashion bows . In the Blackfoot language (Siksiká) the area is known as Mohkínstsis akápiyoyis , meaning "elbow many houses", reflecting its strong settler presence. The shorter form of the Blackfoot name, Mohkínstsis , simply meaning "elbow", is the popular Indigenous term for the Calgary area. In
13120-410: The aviation industry; and the turboshaft engine for helicopter use, pioneered in December 1951 by the aforementioned Kaman K-225, finally gave helicopters an engine with a large amount of power and a low weight penalty. Turboshafts are also more reliable than piston engines, especially when producing the sustained high levels of power required by a helicopter. The turboshaft engine was able to be scaled to
13280-512: The beginning of the oil and gas age in Calgary. Archibald Wayne Dingman and Calgary Petroleum Product's discovery was heralded as the "biggest oil field in the British Empire" at around 19 million cubic metres, and in a three-week period an estimated 500 oil companies sprang into existence. Calgarians were enthusiastic to invest in new oil companies, with many losing life savings during the short 1914 boom in hastily formed companies. Outbreak of
13440-418: The bid for Calgary and spent two years building local support for the project, selling memberships to 80,000 of the city's 600,000 residents. It secured CA$ 270 million in funding from the federal and provincial governments while civic leaders, including Mayor Ralph Klein , crisscrossed the world attempting to woo International Olympic Committee (IOC) delegates. Calgary was one of three finalists, opposed by
13600-435: The blades angle forwards or backwards, or left and right, to make the helicopter move in those directions. The anti-torque pedals are located in the same position as the rudder pedals in a fixed-wing aircraft, and serve a similar purpose, namely to control the direction in which the nose of the aircraft is pointed. Application of the pedal in a given direction changes the pitch of the tail rotor blades, increasing or reducing
13760-677: The building of roads. These operations are referred to as longline because of the long, single sling line used to carry the load. In military service helicopters are often useful for delivery of outsized slung loads that would not fit inside ordinary cargo aircraft: artillery pieces, large machinery (field radars, communications gear, electrical generators), or pallets of bulk cargo. In military operations these payloads are often delivered to remote locations made inaccessible by mountainous or riverine terrain, or naval vessels at sea. In electronic news gathering , helicopters have provided aerial views of some major news stories, and have been doing so, from
13920-573: The city and Calgary's growing reputation as a growing economic hub. The period between 1906 and 1911 was the largest population growth period in the city's history, expanding from 11,967 to 43,704 inhabitants in the five-year period. Several ambitious projects were started during this period including a new City Hall , the Hudson's Bay Department Store , the Grain Exchange Building, and the Palliser Hotel , this period also corresponded to
14080-673: The city is referred to as ʔaknuqtapȼik’ . In the Slavey language , the area is known as Klincho-tinay-indihay meaning "many horse town", referring to the Calgary Stampede and the city's settler heritage. There have been several attempts to revive the Indigenous names of Calgary. In response to the Truth and Reconciliation Commission of Canada , local post-secondary institutions adopted "official acknowledgements" of Indigenous territory using
14240-478: The city, which had fallen into its worst recession in 40 years following the collapse of both oil and grain prices in the mid-1980s. A report prepared for the city in January 1985 estimated the games would create 11,100 man-years of employment and generate CA$ 450 -million in salaries and wages. In its post-Games report, OCO'88 estimated the Olympics created CA$ 1.4 billion in economic benefits across Canada during
14400-406: The cockpit from overhead. The control is called the cyclic because it changes cyclic pitch of the main blades. The result is to tilt the rotor disk in a particular direction, resulting in the helicopter moving in that direction. If the pilot pushes the cyclic forward, the rotor disk tilts forward, and the rotor produces a thrust in the forward direction. If the pilot pushes the cyclic to the side,
14560-571: The country's 800 largest corporations. In 2015, Calgary had the largest number of millionaires per capita of any major Canadian city. In 2022, Calgary was ranked alongside Zürich as the third most livable city in the world, ranking first in Canada and in North America. In 1988, it became the first Canadian city to host the Olympic Winter Games . Calgary was named after Calgary Castle (in Scottish Gaelic, Caisteal Chalgairidh ) on
14720-464: The cyclic, the collective, the anti-torque pedals, and the throttle. The cyclic control is usually located between the pilot's legs and is commonly called the cyclic stick or just cyclic . On most helicopters, the cyclic is similar to a joystick. However, the Robinson R22 and Robinson R44 have a unique teetering bar cyclic control system and a few helicopters have a cyclic control that descends into
14880-528: The early 21st century, as well as recently weaponized utilities such as artillery spotting , aerial bombing and suicide attacks . The English word helicopter is adapted from the French word hélicoptère , coined by Gustave Ponton d'Amécourt in 1861, which originates from the Greek helix ( ἕλιξ ), genitive helikos (ἕλῐκος), "helix, spiral, whirl, convolution" and pteron ( πτερόν ) "wing". In
15040-464: The east on Section 14. The difficulty in crossing the river and the CPR's efforts to persuade residents resulted in the core of the Calgary townsite moving onto Section 15, with the fate of the old townsite sealed when the post office was anonymously moved across the icy Elbow River during the night. The CPR subdivided Section 15 and began selling lots surrounding the station, $ 450 for corner lots and $ 350 for all others; and pioneer Felix McHugh constructed
15200-513: The end of the "Sandstone City" era as steel frames and terracotta facades such as the Burns Building (1913) which were prevalent in other North American cities overtook the unique sandstone character of Calgary. The growing City and enthusiastic residents were rewarded in 1908 with the federally funded Dominion Exhibition . Seeking to take advantage of the opportunity to promote itself, the city spent CA$ 145,000 to build six new pavilions and
15360-439: The event was taken by Max Skladanowsky , but it remains lost . In 1885, Thomas Edison was given US$ 1,000 (equivalent to $ 34,000 today) by James Gordon Bennett, Jr. , to conduct experiments towards developing flight. Edison built a helicopter and used the paper for a stock ticker to create guncotton , with which he attempted to power an internal combustion engine. The helicopter was damaged by explosions and one of his workers
15520-514: The event. The Big Four , as they came to be known, viewed the project as a final celebration of their life as cattlemen. The city constructed a rodeo arena on the fairgrounds and over 100,000 people attended the six-day event in September 1912 to watch hundreds of cowboys from Western Canada, the United States, and Mexico compete for $ 20,000 in prizes. The event generated $ 120,000 in revenue and
15680-441: The facility was expected to cost $ 83 million, but cost overruns pushed the facility to nearly $ 100 million. The Olympic Oval was built on the campus of the University of Calgary . It was the first fully enclosed 400-metre speed skating venue in the world as it was necessary to protect against the possibility of either bitter cold temperatures or ice-melting chinook winds . Seven world and three Olympic records were broken during
15840-486: The first half of the 20th century was that the amount of power produced by an engine was not able to overcome the engine's weight in vertical flight. This was overcome in early successful helicopters by using the smallest engines available. When the compact, flat engine was developed, the helicopter industry found a lighter-weight powerplant easily adapted to small helicopters, although radial engines continued to be used for larger helicopters. Turbine engines revolutionized
16000-467: The first private building on the site. Earlier in the decade it was not expected that the railway would pass near Calgary; instead, the preferred route put forward by people concerned with the young nation's defence was passing near Edmonton and through the Yellowhead Pass . However, in 1881 CPR changed the plans preferring the direct route through the prairies by way of Kicking Horse Pass . Along with
16160-568: The formation of the provincial university. However, the efforts by the community could not sway the government, and the University of Alberta was founded in the City of Strathcona , Premier Rutherford's home, which was subsequently amalgamated into the City of Edmonton in 1912. Calgary was not to be left without higher education facilities as the provincial Normal School opened in the McDougall School building in 1905. In 1910, R. B. Bennett introduced
16320-431: The foundation's corporate fundraising. STARS is a non-profit charitable organization. The Shock Trauma Air Rescue Service Foundation (STARS Foundation) is the fundraising arm for STARS. Funding needs are met through private donations received from individuals, service groups, businesses, corporations and affiliation agreements with provincial governments. STARS also holds lotteries in Alberta and Saskatchewan which are
16480-652: The frontier town, in early 1884 Jack Campbell was appointed as a constable for the community, and in early 1885 the Town Council passed By-law Eleven creating the position of Chief Constable and assigning relevant duties, a precursor to the Calgary Police Service . The first chief constable, John (Jack) S. Ingram, who had previously served as the first police chief in Winnipeg, was empowered to arrest drunken and disorderly people, stop all fast riding in town, attend all fires and council meetings. Calgary Town Council
16640-455: The high operating cost of helicopters cost-effective in ensuring that oil platforms continue to operate. Various companies specialize in this type of operation. NASA developed Ingenuity , a 1.8 kg (4.0 lb) helicopter used to survey Mars (along with a rover). It began service in February 2021 and was retired due to sustained rotor blade damage in January 2024 after 73 sorties. As
16800-473: The idea of vertical flight. In July 1754, Russian Mikhail Lomonosov had developed a small coaxial modeled after the Chinese top but powered by a wound-up spring device and demonstrated it to the Russian Academy of Sciences . It was powered by a spring, and was suggested as a method to lift meteorological instruments. In 1783, Christian de Launoy , and his mechanic , Bienvenu, used a coaxial version of
16960-468: The importance of the moment, the entire Town Council resigned to ensure the new city could choose the first Calgary City Council . Calgary's first municipal election as a city saw Wesley Fletcher Orr garner 244 votes, narrowly defeating his opponent William Henry Cushing 's 220 votes, and Orr was named the first mayor of the City of Calgary. By late 19th century, the Hudson's Bay Company (HBC) expanded into
17120-498: The in-service and stored helicopter fleet of 38,570 with civil or government operators was led Robinson Helicopter with 24.7% followed by Airbus Helicopters with 24.4%, then Bell with 20.5 and Leonardo with 8.4%, Russian Helicopters with 7.7%, Sikorsky Aircraft with 7.2%, MD Helicopters with 3.4% and other with 2.2%. The most widespread model is the piston Robinson R44 with 5,600, then the H125/ AS350 with 3,600 units, followed by
17280-503: The interior and established posts along rivers that later developed into the modern cities of Winnipeg, Calgary and Edmonton. In 1884, the HBC established a sales shop in Calgary. HBC also built the first of the grand "original six" department stores in Calgary in 1913; others that followed were Edmonton, Vancouver , Victoria , Saskatoon , and Winnipeg. In October 1899 the Village of Rouleauville
17440-444: The ire of property owners on the east side of town. Property owners on both sides of Centre Street sought to bring development to their side of Calgary, lost successfully by eastsider James Walker who convinced the Town Council to purchase land on the east side to build a stockyard, guaranteeing meat packing and processing plants would be constructed on the east side. By 1892 Calgary had reached present-day Seventeenth Avenue , east to
17600-662: The lack of an airstrip would make transport via fixed-wing aircraft impossible. The use of transport helicopters to deliver troops as an attack force on an objective is referred to as " air assault ". Unmanned aerial systems (UAS) helicopter systems of varying sizes are developed by companies for military reconnaissance and surveillance duties. Naval forces also use helicopters equipped with dipping sonar for anti-submarine warfare , since they can operate from small ships. Oil companies charter helicopters to move workers and parts quickly to remote drilling sites located at sea or in remote locations. The speed advantage over boats makes
17760-448: The larger 53-storey west tower rise to 215 m (705 ft) and become the largest building in Calgary for 26 years, and a smaller 32-storey east tower rise 130 m (430 ft). The city further expanded the CTrain system, planning began in 1981, and the northeast leg of the system was to be operational in time for the 1988 Olympics. The 1980s oil glut caused by falling demand and
17920-581: The late 1960s. Helicopters have also been used in films, both in front and behind the camera. The largest single non-combat helicopter operation in history was the disaster management operation following the 1986 Chernobyl nuclear disaster . Hundreds of pilots were involved in airdrop and observation missions, making dozens of sorties a day for several months. " Helitack " is the use of helicopters to combat wildland fires . The helicopters are used for aerial firefighting (water bombing) and may be fitted with tanks or carry helibuckets . Helibuckets, such as
18080-519: The lawful mayor of the growingly disorganized Town of Calgary, both holding council meetings and attempting to govern. Word of the issues in Calgary reached the Minister of Justice John Sparrow David Thompson in Ottawa who ordered Justice Thomas Wardlaw Taylor of Winnipeg to conduct an inquiry into the "Case of Jeremiah Travis" . The federal government acted before receiving Taylor's report, Jeremiah Travis
18240-555: The limited power did not allow for manned flight. The introduction of the internal combustion engine at the end of the 19th century became the watershed for helicopter development as engines began to be developed and produced that were powerful enough to allow for helicopters able to lift humans. Early helicopter designs utilized custom-built engines or rotary engines designed for airplanes, but these were soon replaced by more powerful automobile engines and radial engines . The single, most-limiting factor of helicopter development during
18400-614: The male workforce) were officially unemployed. Labour organizations began endorsing candidates for Calgary City Council in the late 1910s and were quickly successful in electing sympathetic candidates to office, including Mayor Samuel Hunter Adams in 1920 . As well the Industrial Workers of the World and its sequel, the One Big Union , found much support among Calgary workers. The city's support of labour and agricultural groups made it
18560-481: The monorotor design, and coaxial-rotor , tiltrotor and compound helicopters are also all flying today. Four-rotor helicopters ( quadcopters ) were pioneered as early as 1907 in France, and along with other types of multicopters , have been developed mainly for specialized applications such as commercial unmanned aerial vehicles (drones) due to the rapid expansion of drone racing and aerial photography markets in
18720-586: The nearby park, the Parco Forlanini. Emmanuel Dieuaide's steam-powered design featured counter-rotating rotors powered through a hose from a boiler on the ground. In 1887 Parisian inventor, Gustave Trouvé , built and flew a tethered electric model helicopter. In July 1901, the maiden flight of Hermann Ganswindt 's helicopter took place in Berlin-Schöneberg; this was probably the first heavier-than-air motor-driven flight carrying humans. A movie covering
18880-464: The nose to pitch down, with a resultant increase in airspeed and loss of altitude. Aft cyclic will cause the nose to pitch up, slowing the helicopter and causing it to climb. Increasing collective (power) while maintaining a constant airspeed will induce a climb while decreasing collective will cause a descent. Coordinating these two inputs, down collective plus aft cyclic or up collective plus forward cyclic, will result in airspeed changes while maintaining
19040-522: The now-eight-year-old settlement sought to form a local government of their own. In the first weeks of 1884, James Reilly who was building the Royal Hotel east of the Elbow River circulated 200 handbills announcing a public meeting on January 7, 1884, at the Methodist Church. At the full meeting Reilly advocated for a bridge across the Elbow River and a civic committee to watch over the interests of
19200-533: The office of Mayor of Calgary. Calgary had only a couple days' peace following the November election before the Calgary Fire of 1886 destroyed much of the community's downtown. Part of the slow response to the fire can be attributed to the absence of functioning local government during 1886. As neither George Murdoch or James Reilly was capable of effectively governing the town, the newly ordered chemical engine for
19360-474: The open traffic of liquor, gambling and prostitution in Calgary despite prohibition in the North-West Territories. Travis' view was accurate as the Royal Commission of Liquor Traffic of 1892 found liquor was sold openly, both day and night during prohibition. Travis associated Clarke with the troubles he saw in Calgary and found him guilty, and sentenced Clarke to six months with hard labour . Murdoch and
19520-557: The opposite of the Liberal-friendly City of Edmonton. However, Calgarians were sympathetic to the cause of workers and supported the development of labour organizations. In 1909, the United Farmers of Alberta (UFA) formed in Edmonton through the merger of two earlier farm organizations as a non-partisan lobbying organization to represent the interests of farmers. The UFA eventually dropped its non-partisan stance when it contested
19680-522: The other members of Council were shocked, and a public meeting was held at Boynton's Hall in which a decision was made to send a delegation to Ottawa to seek an overruling of Travis' judgement by the Department of Justice. The community quickly raised $ 500, and Murdoch and a group of residents headed east. The punishment of Clarke did not escape Hugh Cayley the editor of the Calgary Herald and Clerk of
19840-507: The population increase from 330,575 to 636,107. Population growth became a source of pride, the June 1980 Calgary Magazine exclaimed "Welcome to Calgary! Calgary almost specializes in newcomers..." . High-rise buildings were erected during the economic boom, and more office space opened in Calgary in 1979 than in New York City and Chicago combined. The end of the oil boom is associated with
20000-411: The power normally required to be diverted for the tail rotor to be applied fully to the main rotors, increasing the aircraft's power efficiency and lifting capacity. There are several common configurations that use the counter-rotating effect to benefit the rotorcraft: Tip jet designs let the rotor push itself through the air and avoid generating torque. The number, size and type of engine(s) used on
20160-621: The province's Medical Transportation Coordination Centre. The STARS ELC also provides a site registration program whereby an average of 4,000 remote work sites are connected directly to the centre on any given day for immediate response when emergencies occur. In 1998, the STARS Seconds Count Capital Campaign was launched to buy two STARS helicopters and establish the STARS Legacy Fund. STARS also received full accreditation as an international critical-care provider from
20320-604: The province. In June 2011, STARS was asked by the provincial government to maintain a permanent base within the province. Shortly after, STARS signed a 10-year service agreement with the Government of Manitoba on February 22, 2012, to provide helicopter air ambulance service to Manitoba . The Province of Manitoba expanded the contract of STARS in 2020 as they took over the responsibilities of Lifeflight which include air ambulance and transportation. This contract saw STARS provide air medical crews on fixed-wing aircraft that are operated by
20480-602: The public until Calgary could be incorporated. The attendees were enthusiastic about the committee and on the next evening a vote was held to elect the seven members. A total of 24 candidates were nominated, which equalled 10 per cent of Calgary's male population. Major James Walker received 88 votes, the most amongst the candidates, the other six members were Dr. Andrew Henderson, George Clift King , Thomas Swan, George Murdoch, J. D. Moulton, and Captain John Stewart. The civic committee met with Edgar Dewdney , Lieutenant Governor of
20640-503: The recently organized Calgary Fire Department (Calgary Hook, Ladder and Bucket Corps) was held in the CPR's storage yard due to lack of payment. Members of the Calgary Fire Department broke into the CPR storage yard on the day of the fire to retrieve the engine. In total, fourteen buildings were destroyed with losses estimated at $ 103,200, although no one was killed or injured. The new Town Council sprung into action, drafting
20800-436: The rotor disk tilts to that side and produces thrust in that direction, causing the helicopter to hover sideways. The collective pitch control or collective is located on the left side of the pilot's seat with a settable friction control to prevent inadvertent movement. The collective changes the pitch angle of all the main rotor blades collectively (i.e. all at the same time) and independently of their position. Therefore, if
20960-406: The rotor in cruise, which allows its rotation to be slowed down , thus increasing the maximum speed of the aircraft. The Lockheed AH-56A Cheyenne diverted up to 90% of its engine power to a pusher propeller during forward flight. There are three basic flight conditions for a helicopter: hover, forward flight and the transition between the two. Hovering is the most challenging part of flying
21120-422: The rotor throughout normal flight. The rotor system, or more simply rotor , is the rotating part of a helicopter that generates lift . A rotor system may be mounted horizontally, as main rotors are, providing lift vertically, or it may be mounted vertically, such as a tail rotor, to provide horizontal thrust to counteract torque from the main rotors. The rotor consists of a mast, hub and rotor blades. The mast
21280-592: The side. The Lions Air Ambulance Service's first mission was in December 1985, the transport of a critically ill infant to a hospital in Calgary . In 1988 STARS' received formal recognition as an essential service when the organization was integrated into emergency planning for the Calgary Olympic Winter Games . In 1991 the STARS Edmonton base was established and conducted its first mission in October of that year. The Edmonton base initially operated out of
21440-686: The single largest source of fundraising for the organization. Financial statements and annual reports are available at the STARS website. During the 2023 fiscal period, the Shock Trauma Air Rescue Service charitable organization had an expense total of $ 78,657,331, 87.80% of which went to charitable programs and 12.20% went to management and administration. The funding arm of STARS, the Shock Trauma Air Rescue Service Foundation, had an expense total of $ 56,287,458 during
21600-580: The situation and suggesting the name "Calgary" put forward by Colonel Macleod. Edward Blake , at the time Minister of Justice , agreed with the name and in the spring of 1876, Fort Calgary was officially established. In 1877, the First Nations ceded title to the Fort Calgary region through Treaty 7. In 1881 the federal government began to offer leases for cattle ranching in Alberta (up to 400 km (100,000 acres) for one cent per acre per year) under
21760-418: The size of the helicopter being designed, so that all but the lightest of helicopter models are powered by turbine engines today. Special jet engines developed to drive the rotor from the rotor tips are referred to as tip jets . Tip jets powered by a remote compressor are referred to as cold tip jets, while those powered by combustion exhaust are referred to as hot tip jets. An example of a cold jet helicopter
21920-483: The skies. Since helicopters can achieve a unique aerial view, they are often used in conjunction with police on the ground to report on suspects' locations and movements. They are often mounted with lighting and heat-sensing equipment for night pursuits. Military forces use attack helicopters to conduct aerial attacks on ground targets. Such helicopters are mounted with missile launchers and miniguns . Transport helicopters are used to ferry troops and supplies where
22080-405: The structures to the ground. The local police did not attempt to intervene. Mayor Alexander Lucas had inexplicably left town during the riot, and when he returned home he called the NWMP in to patrol Calgary for three weeks to prevent further riots. Finally on January 1, 1894, Calgary was granted a charter by the 2nd North-West Legislative Assembly , officially titled Ordinance 33 of 1894 ,
22240-475: The tail rotor, such as the ducted fan (called Fenestron or FANTAIL ) and NOTAR . NOTAR provides anti-torque similar to the way a wing develops lift through the use of the Coandă effect on the tail boom. The use of two or more horizontal rotors turning in opposite directions is another configuration used to counteract the effects of torque on the aircraft without relying on an anti-torque tail rotor. This allows
22400-402: The team to Skalbania for US$ 16 million, a record sale price for an NHL team at the time. The team reached the playoffs each year in its first 10 years in Calgary and won the team's only Stanley Cup in 1989 . Public concern existed regarding the potential long-term debt implications that had plagued Montreal following the 1976 Olympics . The Calgary Olympic Development Association led
22560-448: The throttle is to maintain enough engine power to keep the rotor RPM within allowable limits so that the rotor produces enough lift for flight. In single-engine helicopters, the throttle control is a motorcycle-style twist grip mounted on the collective control, while dual-engine helicopters have a power lever for each engine. A compound helicopter has an additional system for thrust and, typically, small stub fixed wings . This offloads
22720-417: The thrust produced by the tail rotor and causing the nose to yaw in the direction of the applied pedal. The pedals mechanically change the pitch of the tail rotor altering the amount of thrust produced. Helicopter rotors are designed to operate in a narrow range of RPM . The throttle controls the power produced by the engine, which is connected to the rotor by a fixed ratio transmission. The purpose of
22880-489: The train was able to make the trip in only a few hours. Smallpox arrived in Calgary in June 1892 when a Chinese resident was found with the disease, and by August nine people had contracted the disease with three deaths.
