81-561: The two larger models were unveiled on October 14, 2014 and the smaller G400 was unveiled on October 4, 2021. The G500 was first delivered on September 27, 2018, and the longer G600 was first delivered August 8, 2019. The G500 will replace the G450 while the larger G600 will succeed the G550 . The smaller G400 meanwhile has not yet been certified, and is not expected to go into production until 2025. Powered by two Pratt & Whitney Canada PW800 turbofans,

162-463: A wedge , in the hands of a human transforms force and movement of the tool into a transverse splitting forces and movement of the workpiece. The hand axe is the first example of a wedge , the oldest of the six classic simple machines , from which most machines are based. The second oldest simple machine was the inclined plane (ramp), which has been used since prehistoric times to move heavy objects. The other four simple machines were invented in

243-403: A 5.5 m (18 ft) longer, 24-27 seat model for airline use. The National Oceanic and Atmospheric Administration (NOAA) operates a GIV-SP (N49RF) modified to fly scientists and crew members at 45,000 feet around tropical cyclones . The aircraft was modified to drop instruments called " dropsondes " to measure windspeed, barometric pressure , humidity , and temperature as they fall to

324-507: A derivation from μῆχος mekhos 'means, expedient, remedy' ). The word mechanical (Greek: μηχανικός ) comes from the same Greek roots. A wider meaning of 'fabric, structure' is found in classical Latin, but not in Greek usage. This meaning is found in late medieval French, and is adopted from the French into English in the mid-16th century. In the 17th century, the word machine could also mean

405-501: A family of twinjet aircraft, mainly for private or business use. They were designed and built by Gulfstream Aerospace , a General Dynamics company based in Savannah, Georgia , United States , from 1985 until 2018. Aircraft power is provided by two Rolls-Royce RB.183 Tay turbofans . Upon delivery of the last G450, over 900 GIV/GIV-SP/G450 units had been produced. The last of the G450’s

486-401: A lever is modeled as a hinged or revolute joint . Wheel: The wheel is an important early machine, such as the chariot . A wheel uses the law of the lever to reduce the force needed to overcome friction when pulling a load. To see this notice that the friction associated with pulling a load on the ground is approximately the same as the friction in a simple bearing that supports the load on

567-420: A machine is "a device for applying power or changing its direction."McCarthy and Soh describe a machine as a system that "generally consists of a power source and a mechanism for the controlled use of this power." Human and animal effort were the original power sources for early machines. Waterwheel: Waterwheels appeared around the world around 300 BC to use flowing water to generate rotary motion, which

648-470: A machine provides a way to understand the performance of devices ranging from levers and gear trains to automobiles and robotic systems. The German mechanician Franz Reuleaux wrote, "a machine is a combination of resistant bodies so arranged that by their means the mechanical forces of nature can be compelled to do work accompanied by certain determinate motion." Notice that forces and motion combine to define power . More recently, Uicker et al. stated that

729-838: A mechanical system is assembled from components called machine elements . These elements provide structure for the system and control its movement. The structural components are, generally, the frame members, bearings, splines, springs, seals, fasteners and covers. The shape, texture and color of covers provide a styling and operational interface between the mechanical system and its users. The assemblies that control movement are also called " mechanisms ." Mechanisms are generally classified as gears and gear trains , which includes belt drives and chain drives , cam and follower mechanisms, and linkages , though there are other special mechanisms such as clamping linkages, indexing mechanisms , escapements and friction devices such as brakes and clutches . The number of degrees of freedom of

810-500: A mechanism, or its mobility, depends on the number of links and joints and the types of joints used to construct the mechanism. The general mobility of a mechanism is the difference between the unconstrained freedom of the links and the number of constraints imposed by the joints. It is described by the Chebychev–Grübler–Kutzbach criterion . The transmission of rotation between contacting toothed wheels can be traced back to

891-412: A point farther from the pivot is greater than the velocity of a point near the pivot, forces applied far from the pivot are amplified near the pivot by the associated decrease in speed. If a is the distance from the pivot to the point where the input force is applied and b is the distance to the point where the output force is applied, then a/b is the mechanical advantage of the lever. The fulcrum of

972-430: A pressure vessel; the expanding steam drives a piston or a turbine. This principle can be seen in the aeolipile of Hero of Alexandria. This is called an external combustion engine . An automobile engine is called an internal combustion engine because it burns fuel (an exothermic chemical reaction) inside a cylinder and uses the expanding gases to drive a piston . A jet engine uses a turbine to compress air which

1053-587: A scheme or plot, a meaning now expressed by the derived machination . The modern meaning develops out of specialized application of the term to stage engines used in theater and to military siege engines , both in the late 16th and early 17th centuries. The OED traces the formal, modern meaning to John Harris ' Lexicon Technicum (1704), which has: The word engine used as a (near-) synonym both by Harris and in later language derives ultimately (via Old French ) from Latin ingenium 'ingenuity, an invention'. The hand axe , made by chipping flint to form

1134-455: A specific application of output forces and movement, (iii) a controller with sensors that compare the output to a performance goal and then directs the actuator input, and (iv) an interface to an operator consisting of levers, switches, and displays. This can be seen in Watt's steam engine in which the power is provided by steam expanding to drive the piston. The walking beam, coupler and crank transform

1215-516: A type inspection authorization to allow in flight evaluation. The five G500 test aircraft have logged more than 3,100 hours over 820 sorties and completed cabin systems, brakes, lighting, fly-over noise and fuel systems tests. The fifth G500, with a complete interior, will be the first to enter service, as a demonstrator, before customer deliveries in early 2018. Through August 20, the G500s had flown 3,460 h over 905 flights, reaching Mach 0.995 and FL530. For

1296-642: A weight of 62,300 lb (28,300 kg), compared to a 3,100 lb (1,400 kg) per h book value. At Mach 0.85 479 kn (887 km/h) TAS, the same G600 burns 2,200 lb (1,000 kg) per h at FL470, ISA-10°C and a weight of 62,000 lb (28,000 kg), below the 2,309 lb (1,047 kg) prediction. Electric and hydraulic systems are from the G650, as well as the digital air data computers, secondary power distribution with electronics, cabin acoustical treatment, primary avionics, satcom, and improved cabin management system. The digital fly-by-wire system

1377-547: Is a GIV-SP model operated by the U.S. Army in a command/executive transport role. The United States Department of Defense C-20A/B/C/D/E aircraft are all Gulfstream III variants. The G450 is a designation for the model GIV-X , approved by the FAA on August 12, 2004, as is the G350 , which has a reduced fuel capacity. Compared to the Gulfstream IV , its fuselage is 12 inches longer and

1458-410: Is burned with fuel so that it expands through a nozzle to provide thrust to an aircraft , and so is also an "internal combustion engine." Power plant: The heat from coal and natural gas combustion in a boiler generates steam that drives a steam turbine to rotate an electric generator . A nuclear power plant uses heat from a nuclear reactor to generate steam and electric power . This power

1539-423: Is called the cam (also see cam shaft ) and the link that is driven through the direct contact of their surfaces is called the follower. The shape of the contacting surfaces of the cam and follower determines the movement of the mechanism. A linkage is a collection of links connected by joints. Generally, the links are the structural elements and the joints allow movement. Perhaps the single most useful example

1620-651: Is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines . Machines can be driven by animals and people , by natural forces such as wind and water , and by chemical , thermal , or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems . Renaissance natural philosophers identified six simple machines which were

1701-603: Is distributed through a network of transmission lines for industrial and individual use. Motors: Electric motors use either AC or DC electric current to generate rotational movement. Electric servomotors are the actuators for mechanical systems ranging from robotic systems to modern aircraft . Fluid Power: Hydraulic and pneumatic systems use electrically driven pumps to drive water or air respectively into cylinders to power linear movement . Electrochemical: Chemicals and materials can also be sources of power. They may chemically deplete or need re-charging, as

1782-499: Is fast, and can fly long distances with ample cabin space for the crew and instruments. In 2009, the NOAA GIV-SP was further modified by the addition of a side-scanning Doppler weather radar to the rear fuselage. This radar is used for storm cloud profiling. In June 1987 a Gulfstream IV set 22 world records in its class in flying west around the world in 45 hr 25 min. The next year another GIV set 11 world records flying east around

1863-401: Is made by chipping stone, generally flint, to form a bifacial edge, or wedge . A wedge is a simple machine that transforms lateral force and movement of the tool into a transverse splitting force and movement of the workpiece. The available power is limited by the effort of the person using the tool, but because power is the product of force and movement, the wedge amplifies the force by reducing

1944-539: Is made of stressed skin, frame and longeron . The G500/G600 is powered by the Pratt & Whitney Canada PW800 series turbofan engines (PW814GA for G500 and PW815GA for G600) which was originally conceived for the Cessna Citation Columbus program. The PW800 is based on the Pratt & Whitney Geared Turbofan core without the gear reduction. The departure from Rolls-Royce Aero Engines is rare for Gulfstream. For

2025-515: Is similar except for new active control sidesticks and dual channel remote electronic units which replace single channel units from G650. The oxygen, cabin pressurization, landing gear control, aircraft health and trend monitoring systems are adapted from the G650. The auxiliary power unit is a Honeywell HTG400G. The cabin pressurization reaches 10.69 psi (0.737 bar). It is equipped with BAE Systems active sidesticks , appearing to be mechanically linked by being electrically back-driven,

2106-420: Is the case with batteries , or they may produce power without changing their state, which is the case for solar cells and thermoelectric generators . All of these, however, still require their energy to come from elsewhere. With batteries, it is the already existing chemical potential energy inside. In solar cells and thermoelectrics, the energy source is light and heat respectively. The mechanism of

2187-421: Is the planar four-bar linkage . However, there are many more special linkages: A planar mechanism is a mechanical system that is constrained so the trajectories of points in all the bodies of the system lie on planes parallel to a ground plane. The rotational axes of hinged joints that connect the bodies in the system are perpendicular to this ground plane. A spherical mechanism is a mechanical system in which

2268-510: The Antikythera mechanism of Greece and the south-pointing chariot of China . Illustrations by the renaissance scientist Georgius Agricola show gear trains with cylindrical teeth. The implementation of the involute tooth yielded a standard gear design that provides a constant speed ratio. Some important features of gears and gear trains are: A cam and follower is formed by the direct contact of two specially shaped links. The driving link

2349-460: The EFVS to provide the only visual cues for landing down to 1,000 ft (300 m) runway visual range , to touchdown and rollout, after 50 test approaches, and testing to lower visibilities could allow dropping the limit. The first G500 was delivered on September 27, 2018. On October 1, Gulfstream announced the acquisition of the nacelle manufacturing line from Nordam. In 2022, its equipped price

2430-478: The Neo-Assyrian period (911–609) BC. The Egyptian pyramids were built using three of the six simple machines, the inclined plane, the wedge, and the lever. Three of the simple machines were studied and described by Greek philosopher Archimedes around the 3rd century BC: the lever, pulley and screw. Archimedes discovered the principle of mechanical advantage in the lever. Later Greek philosophers defined

2511-546: The Renaissance , the dynamics of the Mechanical Powers , as the simple machines were called, began to be studied from the standpoint of how much useful work they could perform, leading eventually to the new concept of mechanical work . In 1586 Flemish engineer Simon Stevin derived the mechanical advantage of the inclined plane, and it was included with the other simple machines. The complete dynamic theory of simple machines

2592-522: The Rolls-Royce Tay fanjet engines provided more thrust than the 11,400 lbs of the Gulfstream III. Speed, noise levels, emissions, fuel economy, range, and cargo capacity were also markedly improved over the earlier model. The Gulfstream IV wing has a weaker, more swept outboard shock resulting in a lower cruise drag. Other benefits arising from this design are a lower root bending moment due to

2673-512: The ancient Near East . The wheel , along with the wheel and axle mechanism, was invented in Mesopotamia (modern Iraq) during the 5th millennium BC. The lever mechanism first appeared around 5,000 years ago in the Near East , where it was used in a simple balance scale , and to move large objects in ancient Egyptian technology . The lever was also used in the shadoof water-lifting device,

2754-491: The lever , pulley and screw as simple machines . By the time of the Renaissance this list increased to include the wheel and axle , wedge and inclined plane . The modern approach to characterizing machines focusses on the components that allow movement, known as joints . Wedge (hand axe): Perhaps the first example of a device designed to manage power is the hand axe , also called biface and Olorgesailie . A hand axe

2835-453: The 79,600 lb (36.1 t) MTOW G500 has a range of 5,300 nautical miles [nmi] (9,800 km; 6,100 mi) while the 94,600 lb (42.9 t) G600 can cover 6,600 nmi (12,220 km) at a speed of Mach 0.85. Both aircraft were unveiled by Gulfstream Aerospace on October 14, 2014 During the second quarter of 2017, 80% of Gulfstream orders were for the G500/G600. The G500

2916-578: The FAA on April 22, 1987. The G-IV entered into service with serial number 1000 in 1987 and was upgraded to the special purpose GIV-SP version at serial number 1214 in 1993. It was later redesignated G400 at serial number 1500. A shorter range variant was created based on the GIV and given the G300 designation in 2002. In 2001, Gulfstream began work on an improved version of the GIV-SP, originally designated GIV-X . It

2997-547: The G450 was developed and received certification in 2004. By 2018, 1990 to 1992 GIVs were for sale at $ 1.6-4.4 million, 1992 to 1999 GIVSPs were listed for $ 1.25-5.2 million, 15-year-old G300s and G400s were available for $ 4.5-7 million and 2006 to 2016 G450s at $ 9.95-23.75 million. Compared to the Gulfstream III , a decision to redesign the wing structure for weight reduction presented an opportunity for an aerodynamic redesign of

3078-532: The G500 in cruise, at FL400, ISA -5°C, total fuel flow is 2,920 lb (1,320 kg)/h at M0.90/510 kn (945 km/h) TAS , 2,400 lb (1,090 kg)/h at M0.85/476 kn (882 km/h) TAS. At FL450, Mach 0.90/506 kn (937 km/h) TAS and ISA -8°C, it burns 2,600 lb (1,200 kg)/h. At Mach 0.90, 512 kn (948 km/h) TAS, the G600 burns 2,960 lb (1,340 kg) per h at FL430, ISA-3°C and

The airframe is primarily composed of high strength aluminum alloys with limited use of steel and titanium alloys . The horizontal stabilizer, fairings, main landing gear doors, rudder and elevators, radome , rear pressure bulkhead and winglets are composite materials . The semi-monocoque fuselage structure

3240-497: The G600 was to happen in 2018 like for the G500. The five flight-test G600s accumulated 1,950 hours in 510 flights, were completing mechanical systems certification testing in May 2018 before airfield -performance testing in summer. By August, 600 flights over 2,290 hours were completed after trials for ice shapes and stall speed testing and before field-performance testing, towards U.S. approval by year-end and deliveries in 2019. By October,

3402-409: The axle of a wheel. However, the wheel forms a lever that magnifies the pulling force so that it overcomes the frictional resistance in the bearing. The classification of simple machines to provide a strategy for the design of new machines was developed by Franz Reuleaux , who collected and studied over 800 elementary machines. He recognized that the classical simple machines can be separated into

3483-411: The bodies move in a way that the trajectories of points in the system lie on concentric spheres. The rotational axes of hinged joints that connect the bodies in the system pass through the center of these circle. A spatial mechanism is a mechanical system that has at least one body that moves in a way that its point trajectories are general space curves. The rotational axes of hinged joints that connect

3564-553: The classic five simple machines (excluding the inclined plane) and were able to roughly calculate their mechanical advantage. Hero of Alexandria ( c.  10 –75 AD) in his work Mechanics lists five mechanisms that can "set a load in motion"; lever, windlass , pulley, wedge, and screw, and describes their fabrication and uses. However, the Greeks' understanding was limited to statics (the balance of forces) and did not include dynamics (the tradeoff between force and distance) or

3645-655: The concept of work . The earliest practical wind-powered machines, the windmill and wind pump , first appeared in the Muslim world during the Islamic Golden Age , in what are now Iran, Afghanistan, and Pakistan, by the 9th century AD. The earliest practical steam-powered machine was a steam jack driven by a steam turbine , described in 1551 by Taqi ad-Din Muhammad ibn Ma'ruf in Ottoman Egypt . The cotton gin

3726-571: The double acting steam engine practical. The Boulton and Watt steam engine and later designs powered steam locomotives , steam ships , and factories . The Industrial Revolution was a period from 1750 to 1850 where changes in agriculture, manufacturing, mining, transportation, and technology had a profound effect on the social, economic and cultural conditions of the times. It began in the United Kingdom , then subsequently spread throughout Western Europe , North America , Japan , and eventually

Range for the G600 was extended by 300 nmi/556 km for both Mach 0.85 to 6,500 nmi/12,038 km and Mach 0.90 to 5,100 nmi/9,445 km. In October 2018, Mach 0.9 range was increased again to 5,500 nmi (10,200 km). Certification and introduction for

4050-519: The first crane machine, which appeared in Mesopotamia c.  3000 BC , and then in ancient Egyptian technology c.  2000 BC . The earliest evidence of pulleys date back to Mesopotamia in the early 2nd millennium BC, and ancient Egypt during the Twelfth Dynasty (1991–1802 BC). The screw , the last of the simple machines to be invented, first appeared in Mesopotamia during

4131-556: The first civil aircraft to be so. The Honeywell Symmetry Flight Deck features four portrait main displays, three touchscreens on the overhead panel instead of stand-alone switches ; there are four force-touchscreens in the glareshield and left and right touch standby displays at each seat.

The bearings that form the fulcrum of a lever and that allow

4374-529: The linear movement of the piston into rotation of the output pulley. Finally, the pulley rotation drives the flyball governor which controls the valve for the steam input to the piston cylinder. The adjective "mechanical" refers to skill in the practical application of an art or science, as well as relating to or caused by movement, physical forces, properties or agents such as is dealt with by mechanics . Similarly Merriam-Webster Dictionary defines "mechanical" as relating to machinery or tools. Power flow through

The Rolls-Royce Tay 611 engines are replaced by 611-8Cs with FADEC, redesigned thrust reversers, nacelles and pylons which increases range and payload, coupled with aerodynamic improvements. Many Gulfstream V-SP improvements are used: the Honeywell advanced flight deck display suite, electrical power generation, cabin temperature control and pressurization, nose and nose landing gear. It also has an improved APU and flap/stab actuation system, redesigned main landing gear wheels and brakes, flight control system hard-over protection system. By

4536-473: The more inboard center of pressure, a lower stall speed due to washout and a larger fuel volume due to increased chord. These aerodynamic improvements result in an increase in range of over 300 nautical miles. In addition to the wing redesign, the Gulfstream IV also became the first business jet to have an entire glass cockpit. The G400 has a large cabin, long range of 4,350 nautical miles (8,060 km) and

4617-408: The movement. This amplification, or mechanical advantage is the ratio of the input speed to output speed. For a wedge this is given by 1/tanα, where α is the tip angle. The faces of a wedge are modeled as straight lines to form a sliding or prismatic joint . Lever: The lever is another important and simple device for managing power. This is a body that pivots on a fulcrum. Because the velocity of

Modern machines are systems consisting of (i) a power source and actuators that generate forces and movement, (ii) a system of mechanisms that shape the actuator input to achieve

4779-403: The primary elements of a machine. Starting with four types of joints, the rotary joint, sliding joint, cam joint and gear joint, and related connections such as cables and belts, it is possible to understand a machine as an assembly of solid parts that connect these joints called a mechanism . Two levers, or cranks, are combined into a planar four-bar linkage by attaching a link that connects

The G600 cabin is 3.7 ft (1.1 m) longer than the G500, allowing up to four passenger zones or three 8.75 ft (2.67 m) long zones, a longer galley and a forward crew rest. The wing is a supercritical design with a 0.87 to 0.88 drag divergence Mach number depending upon lift coefficient. It is based on the G650's wing design with the same 36° sweep. The G600's wingspan will be 8 ft (2.4 m) wider than

4941-592: The prototype was not yet rolled out, Gulfstream was anticipating a more extensive flight-test and certification campaign for the five test aircraft, as the G400 is powered by a different PW800 variant and the US government strengthened some certification requirements after the Boeing 737 Max groundings , but the 2025 first delivery goal remained. The G500 will replace the G450 , flying nearly 30 knots (56 km/h) faster and 18% farther with

5022-467: The rest of the world. Starting in the later part of the 18th century, there began a transition in parts of Great Britain 's previously manual labour and draft-animal-based economy towards machine-based manufacturing. It started with the mechanisation of the textile industries, the development of iron-making techniques and the increased use of refined coal . The idea that a machine can be decomposed into simple movable elements led Archimedes to define

5103-400: The same comfort and design that characterize the G series. Maximum cruise height and speed are 45,000 ft and Mach 0.85. Earlier models were fitted with Honeywell's SPZ 8000 Avionics package. The SPZ 8400 Avionics Package was an option, becoming standard on later models. Its second-hand price was below $ 15 million (~$ 20.7 million in 2023) in 2009. Gulfstream had also considered making

By sampling the cyclone with these dropsondes over a 4,000 mile track around the storm, the forecasters at NOAA's National Hurricane Center and Hurricane Research Division can better predict where the hurricane will be "steered" by the upper level winds. They also predict wind shear that will either increase or decrease a hurricane's strength. The GIV-SP is suited for this mission since it

5346-413: The test aircraft had accumulated 685 flights in over 2,600 hours. The FAA's rigorous review delayed the certification as the test programme had logged more than 3,150h over 840 flights by the end of April 2019, and approval was targeted before the end of June for a second half of 2019 service entry. On June 28, 2019, Gulfstream announced the G600 type and production certificates from the FAA. The first G600

5427-456: The two. With passengers seats removed, it may be configured as three pallets with no passengers or two pallets and eight passengers or one pallet and fourteen passengers. With full seating, the aircraft is capable of accommodating up to twenty-six passengers and a crew of four. A hydraulically operated cargo door is installed on the starboard side of the aircraft, and a ball roller cargo floor is capable of accommodating palletized cargo . The C-20G

5508-399: The wheel and axle and pulleys to rotate are examples of a kinematic pair called a hinged joint. Similarly, the flat surface of an inclined plane and wedge are examples of the kinematic pair called a sliding joint. The screw is usually identified as its own kinematic pair called a helical joint. This realization shows that it is the joints, or the connections that provide movement, that are

5589-540: The wing to reduce cruise drag and increase range. Wing contour modifications had to be restricted to the forward 65% of wing chord so that no redesign of the control surfaces would be necessary. Modification of the inboard wing would have entailed a redesign of the fuselage floor structure, consequently this region of the wing was not modified. Outboard wing modifications were aimed at reducing the peak subcritical pressure coefficient and moving it aft in an effort to reduce shock strength and increase shock sweep. At 12,420 lbs,

5670-565: The world. In 1990, Gulfstream CEO Allen Paulson and a Gulfstream flight crew set 35 international records for around-the-world flight in a GIV.

Through August 20, the four G600s have logged 780 h in 175 flights, the longest lasting 13 h 5 min, it completed testing for initial flight envelope expansion and flying qualities, flutter, brakes, low speed or stall, loads calibration, parameter identification and climb performance,

5913-613: Was applied to milling grain, and powering lumber, machining and textile operations . Modern water turbines use water flowing through a dam to drive an electric generator . Windmill: Early windmills captured wind power to generate rotary motion for milling operations. Modern wind turbines also drives a generator. This electricity in turn is used to drive motors forming the actuators of mechanical systems. Engine: The word engine derives from "ingenuity" and originally referred to contrivances that may or may not be physical devices. A steam engine uses heat to boil water contained in

5994-496: Was delivered on 19 January 2018 after 365 deliveries over 12 years, ending a 30-year production run, to be replaced by the G500 . Gulfstream, in collaboration with Grumman , began work on the Gulfstream IV in March 1983 as a re-engined, stretched fuselage derivative of the Gulfstream III . The first GIV made its maiden flight on September 19, 1985. The model received type certification from

6075-532: Was delivered on August 8, 2019. The first EASA-certified G600 was delivered in December 2020 to an Austrian operator. In 2022, its equipped price was $ 59.5M. On October 4, 2021, Gulfstream introduced the 4,200 nmi (7,780 km) range G400, powered by Pratt & Whitney PW812GA engines with deliveries planned to start in 2025. Priced at $ 34.5 million, the G400 has a shortened G500 fuselage, with 2.5 zones and 10 windows, instead of 3 zones and 14 windows. By March 2022, as

6156-550: Was invented in India by the 6th century AD, and the spinning wheel was invented in the Islamic world by the early 11th century, both of which were fundamental to the growth of the cotton industry . The spinning wheel was also a precursor to the spinning jenny . The earliest programmable machines were developed in the Muslim world. A music sequencer , a programmable musical instrument ,

6237-509: Was later renamed G450 . The G450 is lengthened 1 ft (0.305 m) over the G400 and shares the forward fuselage and larger cockpit of the G550 .

The first music sequencer was an automated flute player invented by the Banu Musa brothers, described in their Book of Ingenious Devices , in the 9th century. In 1206, Al-Jazari invented programmable automata / robots . He described four automaton musicians, including drummers operated by a programmable drum machine , where they could be made to play different rhythms and different drum patterns. During

6480-533: Was to be completed in summer 2018 after 240 were done at the end of May 2018 covering 100,300 nmi in 69 flights, along known icing flight and high-elevation certification tests: the five flight-test G500s made 1,355 flights in 4,955 hours. On July 20, 2018, Gulfstream announced it received both its type certification and production certificate from the FAA, before first delivery in the fourth quarter. As nacelle supplier Nordam filed for bankruptcy on 23 July, initial deliveries will be slowed. Certification allowed

6561-604: Was worked out by Italian scientist Galileo Galilei in 1600 in Le Meccaniche ("On Mechanics"). He was the first to understand that simple machines do not create energy , they merely transform it. The classic rules of sliding friction in machines were discovered by Leonardo da Vinci (1452–1519), but remained unpublished in his notebooks. They were rediscovered by Guillaume Amontons (1699) and were further developed by Charles-Augustin de Coulomb (1785). James Watt patented his parallel motion linkage in 1782, which made
