Hawker Siddeley P.1127 – Photos et vidéos

Lla Hawker P.1127 et le Hawker Siddeley Crécerelle FGA.1 sont les avions expérimentaux et de développement qui ont mené au Hawker Siddeley Harrier, le premier chasseur-bombardier à réaction à décollage et atterrissage verticaux et/ou courts (V/STOL). Le développement du P.1127 a commencé en 1957, profitant de la Bristol Engine Company’s choix d’investir dans la création du moteur à poussée vectorielle Pegasus. Les essais ont commencé en juillet 1960 et, à la fin de l’année, l’avion avait atteint à la fois un décollage vertical et un vol horizontal.

Lla 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 Royal Air Force, 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’des premiers chasseurs à réaction VTOL opérationnels.
