de Havilland (Havker Siddeley) Comet C.Mk.4 Aircraft - photo wallpapers; Megawallpapers.org : The de Havilland Comet of Britain was the world's first commercial jet airliner. It is infamous for being the first to experience the metal fatigue [br]of jet aircraft due to high flight altitudes. Despite that, the Comet [br]and its military derivative, the Nimrod, enjoyed long and productive [br]careers. The origins of the Comet lie in the report produced by the Brabazon Committee [br]during the war. It looked forward to Britain's post war airliner needs [br]and one of the aircraft identified as needing research was for a [br]100-seat jet airliner which was known as the "Type IV". That Geoffrey de Havilland, [br]head of the de Havilland company, was on the committee and de Havilland [br]were working on jet fighters for the RAF was not unrelated. Design work began in 1946 under Ronald Bishop and the intention was to have a commercial aircraft by 1952. The DH.106 Comet first flew on 27 July 1949. At the controls was de Havilland test pilot, John Cunningham, the same man who set a new altitude record two years later in a de Havilland DH 100 Vampire. The design was similar to other airliners except that four of the new, albeit underpowered, de Havilland Ghost 50 Mk1 turbojets [br]were mounted within the wings, in pairs close to the fuselage; this was [br]thought to prove the aircraft more aerodynamic when flying at high [br]speeds. (Unfortunately, the metal skin of the Comet was thinned to [br]compensate for the lack of thrust from the Ghost turbojets; the [br]consequences of this proved disastrous and will be discussed later.) [br]The airliner underwent almost three years of tests and fixes and the [br]first commercial flights did not begin until 22 January 1952 with British Overseas Airways Corporation (BOAC). It became an instant hit with the elite market at whom it was aimed. The first passenger flight was in May from London Heathrow Airport to Johannesburg. [br]The airliner proved to be around twice as fast as contemporary craft [br]and with almost 30,000 passengers carried in the first year over fifty [br]Comets were ordered.[br]Country of origin: GB [br]_________________________________________________________________________________________________ [br]Engines: four Rolls-Royce Avon Mk 545B turbojets of 4763 kg (10,500lb) thrust each [br]_________________________________________________________________________________________________ [br]Wingspan: 35.0 m (114ft 10in) [br]_________________________________________________________________________________________________ [br]Lenght: 35.97 m (118ft) [br]_________________________________________________________________________________________________ [br]Height: 8.69 m (28ft 6in) [br]_________________________________________________________________________________________________ [br]Weight loaded: 73,500 kg (162,000lb) [br]_________________________________________________________________________________________________ [br]Cruising speed: 856 km/h (532mph) [br]_________________________________________________________________________________________________ [br]Service celling: 11,890 m (39,000ft) [br]_________________________________________________________________________________________________ [br]Range: 4168 km (2590 miles) [br]_________________________________________________________________________________________________ [br]Passengers + crew: 101-119 + 3-4 [br]_________________________________________________________________________________________________
