Fairey FD.2 Delta
The Delta 2 was built to investigate the characteristics of flight and control at transonic and supersonic speeds. A 60 degree delta, one feature was a nose that drooped 10 degrees for landing for visibility.
The first made its maiden flight on 6 October 1954. Powered by a 12,000-lb (5443-kg) afterburning thrust Rolls-Royce Avon RA.5, the initial F.D.2 secured the first world air speed record at more than 1000 mph (1609 km/h) in March 1956, when an average of 1132 mph (1821 km/h) was recorded in two flights, piloted by Peter Twiss.
The second aircraft had the 13,000-1b (5896-kg) afterburing thrust Avon RA.28 and helped to expand the F.D.2's flight envelope in an important research programme.
On 10 March 1956 the RA.5-powered aircraft (flown by Peter Twiss) became the first aircraft to set an over-1,000mph world speed record, with an average of two flights of 1,821km/h.
The first machine was later revised as the British Aircraft Corporation 221 to evaluate the ogival wing proposed for the Anglo-French supersonic airliner that finally appeared as the BAC/Aerospatiale Concorde. The Concorde also adopted another F.D.2 feature, the drooping nose that gave the pilot an adequate field of vision for takeoff and landing.
