rare vto aircraft

The Lockheed XFV originated as a result of a proposal issued by the US Navy in 1948 for an aircraft capable of vertical takeoff and landing (VTOL) aboard platforms mounted on the afterdecks of conventional ships. Both Convair and Lockheed competed for the contract but in 1950, the requirement was revised, with a call for a research aircraft capable of eventually evolving into a VTOL ship-based convoy escort fighter. On 19 April 1951, two prototypes were ordered from Lockheed under the designation XFO-1 (company designation was Model 081-40-01). Soon after the contract was awarded, the project designation changed to XFV-1 when the manufacturer's code for Lockheed was changed from O to V.[2]

 

The XFV was powered by a 5,332 hp (3,976 kW) Allison YT40-A-14 turboprop engine driving three-bladed contra-rotating propellers. The tail surfaces were a reflected cruciform v-tail (forming an x) that extended above and below the fuselage. The aircraft had an ungainly appearance on the ground with a makeshift, fixed landing gear attached.[3] Lockheed employees derisively nicknamed the aircraft the "pogo stick" (a direct reference to the rival Convair XFY's name)

 

It was found to totally impractical.
