Designation list of rotorcraft only (everything else carefully weeded out).


P.62 - ?

P.63 - ?

P.72 - General-purpose helicopter (?)

P.74 - Eight-seat helicopter with tip-jets powered by two Napier Oryx gas-turbine engines. Loaded weight: 10,000 lbs. One prototype (WK998 - other sources use the military XK889 serial, so which is correct?) was built but failed to fly due to the underpowered engines. It was promptly scrapped.

  • P.104 - Proposed variant with non-laminar-flow rotor blades. Unbuilt
  • P.105 - Proposal for an alternate variant with the 825hp Napier Oryx NOr.4 turbine generators moved above the cabin to become a universal hub for various fuselage options (described below). Prototype planned to fly in 1958. Unbuilt.
    • Air ambulance.
    • 10-seat passenger transport. Exhibited in model form at the 1955 SBAC Show, Farnborough.
    • P.106 - Proposed derivative of the P.105 power hub for a flying crane variant.
  • P.113 - Proposal for an improved variant with a Rolls-Royce RB108 engine and redesigned rotor system. Unbuilt.

P.76 - ?

P.78 - Military helicopter (?)

P.79 - Military helicopter (?)

P.86 - Design study for a 40-seat helicopter to meet general BEA requirements as a passenger transport. Reportedly to be powered by two Eland engines.

P.91 - Proposed candidate for Air Ministry Specification HR 144T for a two-seat Air Observation Post and liaison helicopter for the British Army. Was to have a two-blade rotor with Saunders-Roe pulse jets. Lost to the Fairey Ultra-Light helicopter.

P.96 - Project derived from the P.74 offered to the US military. Abandoned due to lack of interest.

Awesome list Stingy. Didn't know that the P.105 flying crane had its own designation.


Airplanes are beautiful dreams. Engineers turn dreams into reality.
