Concorde
The Aérospatiale/BAC Concorde () is a retired Franco-British supersonic airliner jointly developed and manufactured by Sud Aviation (later Aérospatiale) and the British Aircraft Corporation (BAC). Studies started in 1954, and France and the UK signed a treaty establishing the development project on 29 November 1962, as the programme cost was estimated at £70 million (£ in ). Construction of the six prototypes began in February 1965, and the first flight took off from Toulouse on 2 March 1969. The market was predicted for 350 aircraft, and the manufacturers received up to 100 option orders from many major airlines. On 9 October 1975, it received its French Certificate of Airworthiness, and from the UK CAA on 5 December. Concorde is a tailless aircraft design with a narrow fuselage permitting a 4-abreast seating for 92 to 128 passengers, an ogival delta wing and a droop nose for landing visibility. It is powered by four Rolls-Royce/Snecma Olympus 593 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supersonic Airliner
A supersonic transport (SST) or a supersonic airliner is a civilian supersonic aircraft designed to transport passengers at speeds greater than the speed of sound. To date, the only SSTs to see regular service have been Concorde and the Tupolev Tu-144. The last passenger flight of the Tu-144 was in June 1978 and it was last flown in 1999 by NASA. Concorde's last commercial flight was in October 2003, with a November 26, 2003 ferry flight being its last airborne operation. Following the permanent cessation of flying by Concorde, there are no remaining SSTs in commercial service. Several companies have each proposed a supersonic business jet, which may bring supersonic transport back again. Supersonic airliners have been the objects of numerous recent and ongoing design studies. Drawbacks and design challenges are excessive noise generation (at takeoff and due to sonic booms during flight), high development costs, expensive construction materials, high fuel consumption, extr ...

Rolls-Royce/Snecma Olympus 593
The Rolls-Royce/Snecma Olympus 593 was an Anglo-French turbojet with reheat (afterburners), which powered the supersonic airliner Concorde. It was initially a joint project between Bristol Siddeley Engines Limited (BSEL) and Snecma, derived from the Bristol Siddeley Olympus 22R engine."Olympus-the first forty years" Alan Baxter, RRHT No15, , p. 135. Rolls-Royce Limited acquired BSEL in 1966 during development of the engine, making BSEL the Bristol Engine Division of Rolls-Royce. Until regular commercial flights by Concorde ceased, in October 2003, the Olympus turbojet was unique in aviation as the only turbojet with reheat powering a commercial aircraft. The overall thermal efficiency of the engine in supersonic cruising flight ( supercruise) was about 43%, which at the time was the highest figure recorded for any normal thermodynamic machine."Not Much of an Engineer" Sir Stanley Hooker An Autobiography, , p. 154.

Droop Nose (aeronautics)
The droop nose or drooped nose is a feature fitted to a small number of aircraft designs, the majority of these being also equipped with delta wings and capable of supersonic speeds. It is typically fitted upon an aircraft that possesses a sharp nose-up attitude during the takeoff and landing phases of flight, which would result in a conventional nose cone obscuring the flight crew's view of the runway and ground alike. On an aircraft fitted with a droop nose, the pilot is able to lower the nose cone, thereby improving visibility. Throughout the majority of a flight, the nose would be kept in the raised position for greater aerodynamic efficiency. Droop noses have typically been installed on supersonic airliners, such as Concorde and the Tupolev Tu-144, and high-speed experimental aircraft, such as the record-breaking Fairey Delta 2 and the Sukhoi T-4 strategic bomber. History The first supersonic delta to receive a drooped nose was the Fairey Delta 2, a Briti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Airways
British Airways (BA) is the flag carrier airline of the United Kingdom. It is headquartered in London, England, near its main hub at Heathrow Airport. The airline is the second largest UK-based carrier, based on fleet size and passengers carried, behind easyJet. In January 2011 BA merged with Iberia, creating the International Airlines Group (IAG), a holding company registered in Madrid, Spain. IAG is the world's third-largest airline group in terms of annual revenue and the second-largest in Europe. It is listed on the London Stock Exchange and in the FTSE 100 Index. British Airways is the first passenger airline to have generated more than US$1 billion on a single air route in a year (from 1 April 2017, to 31 March 2018, on the New York-JFK - London-Heathrow route). BA was created in 1974 after a British Airways Board was established by the British government to manage the two nationalised airline corporations, British Overseas Airways Corporation and British Eu ...

Sud Aviation
Sud Aviation (, ''Southern Aviation'') was a French state-owned aircraft manufacturer, originating from the merger of Sud-Est ( SNCASE, or ''Société nationale des constructions aéronautiques du sud-est'') and Sud-Ouest ( SNCASO or ''Société nationale des constructions aéronautiques du sud-ouest'') on 1 March 1957. Both companies had been formed from smaller privately owned corporations that had been nationalized into six regional design and manufacturing pools just prior to the Second World War. The company became a major manufacturer of helicopters, designing and producing several types which went on to be built in large numbers, including the Alouette II (the first production helicopter powered by a gas turbine engine; first flight in 1955), the Puma (1965) and Gazelle (1967). During 1967, an agreement between the British and French governments arranged for joint production and procurement of the Puma and Gazelle, together with the British Westland Lynx. Sud Aviation a ...

Delta Wing
A delta wing is a wing shaped in the form of a triangle. It is named for its similarity in shape to the Greek uppercase letter delta (Δ). Although long studied, it did not find significant applications until the Jet Age, when it proved suitable for high-speed subsonic and supersonic flight. At the other end of the speed scale, the Rogallo flexible wing proved a practical design for the hang glider and other ultralight aircraft. The delta wing form has unique aerodynamic characteristics and structural advantages. Many design variations have evolved over the years, with and without additional stabilising surfaces. General characteristics Structure The long root chord of the delta wing and minimal structure outboard make it structurally efficient. It can be built stronger, stiffer and at the same time lighter than a swept wing of equivalent lifting capability. Because of this it is easy and relatively inexpensive to build – a substantial factor in the success of the M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Aircraft Corporation
The British Aircraft Corporation (BAC) was a British aircraft manufacturer formed from the government-pressured merger of English Electric Aviation Ltd., Vickers-Armstrongs (Aircraft), the Bristol Aeroplane Company and Hunting Aircraft in 1960. Bristol, English Electric and Vickers became "parents" of BAC with shareholdings of 20%, 40% and 40% respectively. BAC in turn acquired the share capital of their aviation interests and 70% of Hunting Aircraft several months later. History Formation BAC's origins can be traced to a statement issued by the British government that it expected the various companies involved in the aircraft, guided weapons and engine industries to consolidate and merge with one another. Furthermore, the government also promised incentives to motivate such restructuring; the maintenance of government research and development spending and the guarantee of aid in launching "promising new types of civil aircraft". One particularly high-profile incentive was t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aérospatiale
Aérospatiale (), sometimes styled Aerospatiale, was a French state-owned aerospace manufacturer that built both civilian and military aircraft, rockets and satellites. It was originally known as Société nationale industrielle aérospatiale (SNIAS). Its head office was in the 16th arrondissement of Paris. The name was changed to Aérospatiale during 1970. During the 1990s, Aérospatiale underwent several significant restructures and mergers. Its helicopter division was, along with Germany's DaimlerBenz Aerospace AG (DASA), combined to form the Eurocopter Group. In 1999, the majority of Aérospatiale, except for its satellite activities, merged with French conglomerate Matra's defense wing, Matra Haute Technologie, to form Aérospatiale-Matra. That same year, the satellite manufacturing division merged with Alcatel to become Alcatel Space, now Thales Alenia Space. In 2001, Aérospatiale-Matra merged with Spanish aviation company Construcciones Aeronáuticas SA (CASA) and G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

First Flight
The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. The maiden flight of a new aircraft type is always a historic occasion for the type and can be quite emotional for those involved. In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot. Maiden flights are usually accompanied by a chase plane, to verify items like altitude, airspeed, and general airworthiness. A maiden flight is only one stage in the development of an aircraft type. Unless the type is a pure research aircraft (such as the X-15), the aircraft must be tested extensively to ensure that it delivers the desired performance with an acceptable margin of safety. In the case of civilian aircraft, a new t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
