Hawker Siddeley P.1127 – Foton &; Videor

Den Hawker P.1127 och Hawker Siddeley Kestrel FGA.1 är experiment- och utvecklingsflygplanet som ledde till Hawker Siddeley Harrier, den första vertikala och / eller korta start och landning (V / STOL) jetjaktbombaren. Utvecklingen av P.1127 började 1957 och utnyttjade Bristol Engine Companys val att investera i skapandet av Pegasus vectored-thrust-motor. Testerna började i juli 1960 och i slutet av året hade flygplanet uppnått både vertikal start och horisontell flygning.

Den Hawker Siddeley P.1127 was a British experimental jet aircraft developed in the late 1950s and early 1960s. It was the first aircraft to demonstrate the ability to take off and land vertically using vectored thrust from a single engine. The P.1127 was designed by Sir Sydney Camm and his team at Hawker Aircraft, with the assistance of the Bristol Engine Company and the Royal Aircraft Establishment. The P.1127 was powered by a Bristol Pegasus turbofan engine, which could rotate its four nozzles to direct the thrust either horizontally for forward flight or vertically for hovering.
The P.1127 had a conventional wing and tail configuration, but with small wingtip jets for lateral stability and control in hover mode. The P.1127 made its first tethered flight in October 1960, and its first free flight in November 1960. It underwent extensive testing and evaluation by both Hawker and the Kungliga flygvapnet, proving the feasibility and potential of vertical take-off and landing (VTOL) aircraft. The P.1127 was the precursor of the Hawker Siddeley Kestrel and the Harrier, which became the world’s first operational VTOL jet fighters.
