59-731: For the CF-105 Arrow project, Avro Canada had originally intended to use one of three different engines, all UK designs: Rolls-Royce RB.106 , the Bristol B.0L.4 Olympus , or a license-built version of the Olympus, the Curtiss-Wright J67. The RB.106 and J67 were selected as the primary and backup engines for the new design. However, both the RB.106 and J67 were cancelled during the Arrow's design phase, too far into

118-786: A "five-shilling meal" at the Swan and Royal hotel in Clitheroe , Stanley Hooker and Ernest Hives of Rolls-Royce agreed with Spencer Wilks of the Rover Car Company that Rolls-Royce would take over top secret work on the development of the jet engine. An exchange of assets followed with Rover and in the post- World War II period Rolls-Royce made significant advances in gas turbine engine design and manufacture. The Dart and Tyne turboprop engines were particularly important, enabling airlines to cut times for shorter journeys whilst jet airliners were introduced on longer services. The Dart engine

236-465: A drop-in replacement, but it would have produced about twice the thrust (with reheat) at 21,750 lbf (96.7 kN). The two-shaft layout was relatively advanced for the era; the single-shaft de Havilland Gyron matched it in power terms, while the two-spool Bristol Olympus was much less powerful at its then-current state of development. Apart from being expected to power British aircraft such as those competing for Operational Requirement F.155 , it

295-463: A reputation for superior engineering by manufacturing the "best car in the world" The business was incorporated as "Rolls-Royce Limited" in 1906, and a new factory in Derby was opened in 1908. The First World War brought the company into manufacturing aero-engines. Joint development of jet engines began in 1940, and they entered production in 1944. Rolls-Royce has since built an enduring reputation for

354-416: A yacht, Silver Ghost . Unofficially the press and public immediately picked up and used Silver Ghost for all the 40/50 cars made until the introduction of the 40/50 Phantom in 1925. The new 40/50 was responsible for Rolls-Royce's early reputation with over 6,000 built. Its chassis was used as a basis for the first British armoured car used in both world wars . Aero-engine manufacturing began in 1914 at

Building on Royce's good reputation established with his cranes , they quickly developed

472-656: The Bentley 3½ Litre . Advertised as "the silent sports car" and very much in the Rolls-Royce mould, it was a private entry by Eddie Hall (but supported by Rolls-Royce) in the 1934, 1935 and 1936 RAC Tourist Trophy sports car races on the Ards Circuit , where it recorded the fastest average speed in each year (ahead of Lagondas and Bugattis). This helped the Sales Department as old Bentley customers had been inclined to doubt that

531-488: The Hawker Siddeley Trident , BAC One-Eleven , Grumman Gulfstream II and Fokker F28 Fellowship . During the late 1950s and 1960s there was a significant rationalisation of all aspects of British aerospace and this included aero-engine manufacturers. In 1966 Rolls-Royce acquired Bristol Siddeley (which had resulted from the merger of Armstrong Siddeley and Bristol Aero Engines in 1959) and incorporated it as

708-641: The Rolls-Royce 10 hp , was unveiled at the Paris Salon in December 1904. Rolls-Royce Limited was formed on 15 March 1906, by which time it was apparent that new premises were required for production of cars. After considering sites in Manchester, Coventry , Bradford and Leicester , it was an offer from Derby 's council of cheap electricity that resulted in the decision to acquire a 12.7 acres (51,000 m ) site on

767-473: The Rolls-Royce 30 hp . Initially designated the 40/50 hp, this was Rolls-Royce's first all-new model. In March 1908, Claude Johnson , Commercial Managing Director and sometimes described as the hyphen in Rolls-Royce , succeeded in persuading Royce and the other directors that Rolls-Royce should concentrate exclusively on the new model, and all the earlier models were duly discontinued. Johnson had an early example finished in silver and named, as if it were

826-548: The Royal Aircraft Factory asked Rolls-Royce to design a new 200 hp (150 kW) engine. Despite initial reluctance, they agreed, and during 1915, developed Rolls-Royce's first aero engine, the twelve-cylinder Eagle . This was quickly followed by the smaller six-cylinder Hawk , the 190 hp (140 kW) Falcon and, just before the end of the war, the larger 675 hp (503 kW) Condor . Throughout World War I, Rolls-Royce struggled to build aero engines in

885-493: The 1950s and 1960s left a small number of major airframe manufacturers based in only a few countries. The competition for the very large contracts to supply their engines grew intense. Expensive research and development became vital. Real profits came from the maintenance contracts which might peak a whole human generation later. By the 1980s it was said that each generation of aero engines cost around 10 times that of its parent. At this time Rolls-Royce employed 80,000 people and it

At that time its engines were installed in the aircraft of more than 270 civil carriers and were used by 110 armed services and 700 operators of executive and corporate aircraft. In addition, its turbines powered

Bristol Siddeley, with its principal factory at Filton , near Bristol , had a strong base in military engines, including the Olympus , Viper , Pegasus (vectored thrust) and Orpheus . They were also manufacturing the Olympus 593 Mk610 to be used in Concorde in collaboration with SNECMA. They also had a turbofan project with SNECMA. According to the prospectus published for

The new aircraft with its three RB211 engines left USA for the first time and arrived in Paris on 1 June 1971. At Palmdale California the L-1011 received its US Federal Aviation Administration's certificate of airworthiness on 14 April 1972, nine months late. On

1180-466: The bank would withdraw its overdraft facility on which Rolls-Royce depended at that time. Nevertheless, believing that war was likely to be short-lived the directors initially decided not to seek government work making aero engines. However, this position was quickly reversed and Rolls-Royce was persuaded by the War Office to manufacture fifty air-cooled V8 engines under licence from Renault . Meanwhile,

1239-464: The colour of the Rolls-Royce radiator monogram was changed from red to black; because the red sometimes clashed with the coachwork colour selected by clients, and not as a mark of respect for the death of Royce later that year as is commonly stated. The British government built a shadow factory in Crewe in 1938 for Rolls-Royce where they could build their Merlin and Griffon aero engines. Car production

Rolls-Royce plc still owns and operates Rolls-Royce's principal business, although, since 2003, it is technically a subsidiary of Rolls-Royce Holdings plc , a listed holding company . Henry Royce started an electrical and mechanical business in 1884. He made his first car, a two-cylinder Royce 10, in his Manchester factory in 1904. Henry Royce

Rolls-Royce obtained consent to drop the '1971' distinction from its company name in 1977, at which point it became known once again as "Rolls-Royce Limited". The Rolls-Royce business remained nationalised until 1987 when, after having renamed

1416-451: The day the chairman of Lockeed said "...we know that in airline service it (RB211) will prove itself to be one of the leading power plants in aviation history". The first airliner was delivered to Eastern Air Lines on 5 April 1972 but it had been beaten in the race to production by McDonnell Douglas 's DC-10 . Rolls-Royce Motors Limited was incorporated on 25 April 1971, two and a half months after Rolls-Royce fell into receivership. Under

1475-461: The development and manufacturing of engines for military and commercial aircraft. In the late 1960s, Rolls-Royce was adversely affected by the mismanaged development of its advanced RB211 jet engine and consequent cost over-runs, though it ultimately proved a great success. In 1971, the owners were obliged to liquidate their business. The useful portions were bought by a new government-owned company named "Rolls-Royce (1971) Limited", which continued

1534-599: The engine's successful operation under sustained high inlet temperatures, and the ability to make normal relights up to 60,000 feet (18,000 m), the limit of the wind tunnel in which the tests were conducted. By 1958, the Iroquois had completed more than 5,000 hours of ground running, and many thousands of hours had also been spent testing the engines' principal components, at the Orenda testing facilities at Nobel , near Parry Sound, Ontario. In 1956, an American Boeing B-47 Stratojet

1593-496: The first car being completed on January 17, 1921, that being a Silver Ghost with a documented chassis price of US$ 11,750 ($ 200,715 in 2023 dollars ). When the factory closed in 1931, 2,944 total vehicles had been produced. It was located at the former American Wire Wheel factory on Hendee Street, with the administration offices at 54 Waltham Ave. Springfield was the earlier location for the Duryea Motor Wagon Company ,

1652-698: The government's request. The first model, the Rolls-Royce Eagle, entered production in 1915. Two Eagles powered Alcock and Brown 's first non-stop trans-Atlantic crossing by aeroplane mounted on their converted Vickers Vimy bomber. In 1921, Rolls-Royce opened a new factory in Springfield, Massachusetts in the United States to help meet a three-year backlog demand where a further 1,703 "Springfield Ghosts" and 1,241 Phantoms were built. This factory, called Rolls-Royce of America, Inc., operated for 10 years, with

1711-525: The location where the first American gasoline-powered vehicle was built. Bodies for American assembly were supplied by Brewster & Co. in Long Island City, New York . After the First World War, Rolls-Royce successfully avoided attempts to encourage British car manufacturers to merge. Faced with falling sales of the 40/50 Silver Ghost in short-lived but deep postwar slumps Rolls-Royce introduced

1770-494: The low pressure turbine assembly and the metal insulation blanket found at the rear of the engine. This heat resistant nickel-chrome alloy retains its strength at high temperatures and resists oxidation and corrosion. The primary reason for using these advanced metals was to save weight and improve performance, creating an engine with a 5:1 thrust to weight ratio that could produce a sea level dry thrust of 19,250 lb (26,000 lb with afterburner). Wind tunnel tests demonstrated

1829-459: The naval vessels of 25 different nations. Over 175 industrial customers operated Rolls-Royce gas turbines for power generation, gas and oil pumping and other industrial purposes. Its single most important customer was the United Kingdom's government. In the preceding five years about 70 per cent of production went outside the United Kingdom.

1888-419: The new Crewe Bentley could out-perform its famous predecessors. Immediately after World War II (when fully-tooled pressed-steel cars were produced in the factory, rather than chassis sent to a coachbuilder for a custom-built body ) until 2002, standard Bentley and Rolls-Royce cars were usually nearly identical – Bentleys were badge engineered ; only the radiator grille and minor details differed. In 1933,

It continued to take on precision engineering work on sub-contracts. In June 1971, it acquired all the business and assets used by the motor car and diesel divisions of Rolls-Royce and Mulliner Park Ward. Rolls-Royce Motors' permitted uses of

2006-634: The plant to be shut down. The continuing support of the trade creditors was also achieved by the receiver in spite of threats to demand immediate payments in full and to withdraw supplies. The first asset sold was British Aircraft Corporation bought equally by Vickers and GEC. The receiver floated Rolls-Royce Motors in 1973. The new owner, Rolls-Royce (1971) Limited, had among its board members Lord Cole (a former chairman of Unilever), Sir Arnold Weinstock (managing director of GEC), Hugh Conway (managing director Rolls-Royce Gas Turbines), Dr Stanley Hooker (Rolls-Royce Bristol), Sir William Cook (an adviser to

2065-552: The program to select the Olympus. Orenda Engines quickly responded with the PS.13 Iroquois design. In overall design terms, the PS.13 was similar to the RB.106, using a "two-spool" layout with low-pressure and high-pressure sections of the compressor for added efficiency. It differed slightly in being somewhat more powerful, especially in afterburner. The design also incorporated a number of new design features intended to improve simplicity and lightness. With this in mind, Orenda pioneered work in

2124-571: The quantities required by the War Office . However, with the exception of Brazil Straker in Bristol, Rolls-Royce resisted pressure to license production to other manufacturers, fearing that the engines' much admired quality and reliability would risk being compromised. Instead the Derby factory was extended to enable Rolls-Royce to increase its own production rates. By the late 1920s, aero engines made up most of Rolls-Royce's business. Henry Royce's last design

2183-452: The range of diesel engines included: In 1907, Charles Rolls, whose interests had turned increasingly to flying, tried unsuccessfully to persuade Royce and the other directors to design an aero engine. When World War I broke out in August 1914, Rolls-Royce (and many others) were taken by surprise. As a manufacturer of luxury cars, Rolls-Royce was immediately vulnerable, and Claude Johnson thought

2242-484: The recognition Rolls-Royce had no resources left and it voluntarily entered receivership 4 February 1971. There were said to have been acrimonious telephone conversations between US president Richard Nixon and the British prime minister Edward Heath but these were subsequently denied. Responding to questions as to how the situation could have arisen the chief executive advised that in their calculations they were guided by

2301-664: The remaining capital of Park Ward Limited which, since 1936, in conjunction with Rolls-Royce had been building short production runs of all-metal saloon bodies on Bentley chassis. In 1959, Rolls-Royce bought coachbuilder H J Mulliner and the two businesses were put together as H J Mulliner Park Ward. Luxury cars did not fit with the new mood of post-war austerity. After starting design and development of what became their C series diesel engine range in 1948, Rolls-Royce began to produce diesel engines in 1951. By 1955, it provided diesel engines for automotive, railway, industrial, earth-moving and marine use. Sentinel (Shrewsbury) Limited

2360-500: The sale. However the government would not fix a purchase price for the assets until the situation became clearer because without a continuing business many of them might be worthless. In the meantime the government would use the assets to continue the activities of the aero-engine, marine and industrial gas turbine and small engine divisions that were important to national defence, the collective programmes with other countries and to many air forces and civil airlines. A new company (1971)

2419-565: The small sports/racing car maker and potential rival, after the latter's finances failed to weather the onset of the Great Depression . Rolls-Royce stopped production of the new Bentley 8 Litre , which was threatening sales of their current Phantom, disposed of remaining Bentley assets and using just the Bentley name and its repute. After two years of development Rolls-Royce introduced a new and quite different ultra-civilised medium-size Bentley,

2478-549: The smaller, affordable Twenty in 1922, effectively ending the one-model policy followed since 1908. The new 40/50 hp Phantom replaced the Silver Ghost in 1925. The Phantom III, introduced in 1936, was the last large pre-war model. A strictly limited production of Phantoms for heads of state recommenced in 1950 and continued until the Phantom VI ended production in the late 1980s. In 1931, Rolls-Royce acquired Bentley ,

2537-549: The southern edge of that city. The new factory was largely designed by Royce, and production began in early 1908, with a formal opening on 9 July 1908 by Sir John Montagu . The investment in the new company required further capital to be raised, and on 6 December 1906, £100,000 of new shares were offered to the public . In 1907, Rolls-Royce bought out C.S. Rolls & Co. The non-motor car interests of Royce Ltd. continued to operate separately. During 1906 Royce had been developing an improved six-cylinder model with more power than

2596-407: The success of their estimates in the launching of their Spey engine. Had the government simply nationalised Rolls-Royce it would have been unable to avoid the obligations to Lockheed. The situation was handled in the usual manner with the assets being sold for cash, in this case to the government, leaving the massive liabilities to be dealt with by Rolls-Royce Limited using the funds realised by

2655-508: The use of titanium in engines, with 20% by weight of the Iroquois (mainly the compressor rotor blades) consisting of this metal. Titanium has light weight, high strength and good temperature and corrosion resistance. It was estimated that the engine would be 850 pounds (386 kg) lighter than if steel had been used. During the early 1950s, this material was in short supply, and the lack of knowledge of its physical properties and fabrication techniques created problems which had to be overcome. It

2714-463: The war most Rolls-Royce flight testing of engines was carried out from Hucknall Aerodrome . The Merlin crossed over into military land-vehicle use as the Meteor powering the Centurion tank among others. Many Meteor engines used engine blocks and parts that failed requirements for high performance engines, but were suitable for use in the derated 480 kW (640 hp) Meteor. In December 1942, over

2773-470: The war, in 1946, Rolls-Royce and Bentley car production moved to Crewe where they began to assemble complete Rolls-Royce and Bentley cars with body pressings made by the Pressed Steel Company (see W. A. Robotham ). Previously they had built only the chassis, leaving the bodies to specialist coach-builders. In 1939, Rolls-Royce brought one of the specialist coachbuilders completely in-house by buying

2832-599: Was Britain's 14th largest company in terms of manpower. It was generally known that problems had recently arisen requiring government support of the RB211 programme as one outcome of intense financial competition with Pratt & Whitney and General Electric for the original RB211 contract. In the new year of 1971 financial problems caused largely by development of this new RB211 turbofan engine designed and developed for Lockheed Aircraft Corporation 's new L-1011 TriStar led, after several government-provided cash subsidies, to

2891-408: Was also very expensive relative to the more common materials such as steel and aluminum. It was recognized that if the engine parts could be designed with titanium, then the supporting structure could also be lightened due to reduced forces within the engine, with an overall saving in weight. Other parts, such as gearbox casings were made with a magnesium alloy. Inconel was used to make the blades in

2950-535: Was an advanced military turbojet engine design of the 1950s by Rolls-Royce Limited . The work was sponsored by the Ministry of Supply . The RB.106 project was cancelled in March 1957, at a reported total cost of £100,000. The RB.106 was a two-shaft design with two axial flow compressors each driven by its own single stage turbine and reheat . It was of similar size to the Rolls-Royce Avon , allowing it to be used as

3009-435: Was bought in 1956. Sentinel made machine tools and industrial locomotives. Rolls-Royce took over Sentinel's Shrewsbury factory for diesel engine production and all its diesel work was transferred there. West Riding manufacturer of diesel shunting locomotives, Thomas Hill (Rotherham) Limited , was added to the group in 1963. In 1973, when Shrewsbury activities were put under the umbrella of new owner, Rolls-Royce Motors,

The CL-52 was the only B-47 used by any foreign service. The program was cancelled, along with the Arrow, on 20 February 1959. The Canada Aviation and Space Museum in Ottawa houses the nose and cockpit section of Arrow RL 206, along with various wing and fuselage components, and

3127-555: Was incorporated that May to purchase substantially the whole of the undertakings and assets of the four divisions of Rolls-Royce connected with gas turbine engines. The original company, Rolls-Royce Limited, was placed in liquidation on 4 October 1971. Asking their own government for support Lockheed warned that a switch to either Pratt & Whitney or General Electric engines would delay production by an extra six months and might force Lockheed into bankruptcy. The receiver negotiated with Lockheed which consented to waive damages allowing

3186-658: Was introduced to Charles Rolls at the Midland Hotel, Manchester on 4 May of that year. Rolls was proprietor of an early motor car dealership, C.S. Rolls & Co. in Fulham . In spite of his preference for three- or four-cylinder cars, Rolls was impressed with the Royce 10, and in a subsequent agreement on 23 December 1904 agreed to take all the cars Royce could make. There would be four models: All would be badged as Rolls-Royces and be sold exclusively by Rolls. The first Rolls-Royce car,

3245-503: Was loaned to the RCAF to flight test the Iroquois for use in the CF-105. Canadair , the sub-contractor, attached an Iroquois to the right side of the bomber's rear fuselage, near the tail, simply because there was no other place to mount it. Designated CL-52 by Canadair, it was a nightmare to fly, since the thrust was asymmetrical; this created great problems for flight control. After the Arrow project

3304-635: Was moved there in 1946 for space to construct bodies and to leave space for aero engines at Derby. The site was bought from the government in 1973. It is now Bentley Crewe . In 1940, a contract was signed with the Packard Motor Car Company in Detroit, Michigan, for the production of Merlin aero-engines for World War II in the USA. Production focused on aero engines but a variant of the Merlin engine, known as

3363-583: Was selected to be the powerplant for the Avro Canada CF-105 Arrow . The American company Westinghouse was reported in 1956 to be serious about acquiring a licence to build the RB.106. A scaled-up version of the RB.106 intended for F.155 was the Rolls-Royce RB.122 . The competing Bristol two-spool engine to the same specification was to have been the Bristol Zeus . However funding was cut with

3422-644: Was the Merlin aero engine, which was first flown in prototype form in 1935, although he had died in 1933. This was developed from the R engine, which had powered a record-breaking Supermarine S.6B seaplane to almost 400 mph (640 km/h) in the 1931 Schneider Trophy . The Merlin was a powerful supercharged V12 engine and was fitted into many World War II aircraft: the British Hawker Hurricane , Supermarine Spitfire , de Havilland Mosquito (twin-engine), Avro Lancaster (four-engine) (a development of

3481-638: Was used in Armstrong Whitworth AW.660 Argosy , Avro 748 , Fokker F27 Friendship , Handley Page Herald and Vickers Viscount aircraft, whilst the more powerful Tyne powered the Breguet Atlantique , Transall C-160 , Short Belfast , and Vickers Vanguard , and the SR.N4 hovercraft . Many of these turboprops are still in service. Amongst the jet engines of this period was the RB163 Spey , which powers
