Hawker Siddeley P.1127

Hawker Siddeley P.1127
Kraju	Uk
Typu	Eksperymentalny samolot V/STOL
Pierwszy lot	19 listopada 1960 (str. 1127) – 7 marca 1964 (pustułka)
Zbudowany	6 P.1127s – 9 pustułek

Tthe Hawker P.1127 oraz Hawker Siddeley Kestrel FGA.1 to eksperymentalne i rozwojowe samoloty, które doprowadziły do Hawker Siddeley Harrier, pierwszego pionowego i / lub krótkiego startu i lądowania (V / STOL) odrzutowego myśliwca-bombowca. Prace nad P.1127 rozpoczęły się w 1957 roku, wykorzystując wybór Bristol Engine Company do zainwestowania w stworzenie silnika wektorowo-oporowego Pegasus. Testy rozpoczęły się w lipcu 1960 roku i do końca roku samolot osiągnął zarówno pionowy start, jak i lot poziomy.

Development and the Tripartite Evaluation

The Hawker Siddeley Kestrel was an experimental V/STOL (Vertical/Short Take-Off and Landing) aircraft developed in the early 1960s as a follow-up to the P.1127. It served as a critical technology demonstrator for the “vectored thrust” concept. In 1964, a unique “Tripartite Evaluation Squadron” was formed, consisting of pilots and ground crews from the UK, the United States, and West Germany. This joint team spent a year proving that a jet fighter could operate from unprepared fields, forest clearings, and small ship decks, effectively laying the operational groundwork for the future Harrier.

The Pegasus Engine and Vectored Thrust

Single-Engine Solution: Unlike other VTOL designs that used multiple “lift engines,” the Kestrel used one Pegasus turbofan with four rotating nozzles to direct all thrust for both hover and forward flight.
Reaction Control System: Because aerodynamic surfaces (flaps/rudders) don’t work in a hover, the Kestrel used “puffer” jets at the nose, tail, and wingtips, fed by engine bleed air, to maintain balance.
Landing Gear: It featured a unique “zero-track” bicycle landing gear—two main wheels in tandem under the fuselage and small outrigger wheels on the wingtips for stability.
VIFF Capability: During testing, pilots discovered they could “Vector In Forward Flight” (VIFF), rotating the nozzles during air combat to decelerate rapidly or turn tighter than conventional aircraft.

Transition to the United States

The XV-6A Designation: After the tripartite trials ended in 1965, six of the aircraft were shipped to the US for further testing by the Army, Navy, and Air Force, receiving the American designation XV-6A.
Marine Corps Interest: While the US Air Force and Army eventually passed on the design, the US Marine Corps was so impressed by the XV-6A trials that they pushed for the acquisition of its successor, the AV-8A Harrier.
Preservation: Several Kestrels survive today, most notably at the National Museum of the US Air Force in Dayton, Ohio, and the Pima Air & Space Museum in Arizona.
