Aircraft Background Edit
Enthusiasm for variable geometry continued and in 1962, the Admiralty released OR.356. This requirement specified a variable geometry research aircraft to be built in two sizes to eventually replace the de Havilland Vixen and the heavier Blackburn Bucaneer.
Vickers Supermarine had been continually working on the challenges of variable geometry. This wing configuration allowed the lift benefits for low speed flight, and hence STOL performance, with benefits for low drag and stability at high speed. The challenge was that variable geometry mechanisms made the aircraft around 8% heavier, so eliminated the take off and landing performance due to increased weight.
The 583 incorporated the earlier designs of the Vickers Type 581, but incorporated a horizontal stabilizer that enabled better pitch control to remove the need for a lift engine. TSR2 research was incorporated and the 583 featured forward sloping air intakes incorporating a ramp on the top side to slow down supersonic airflow. This intake design was chosen above earlier outward (Vickers Type 571) and round (TSR2) intakes and would be seen on Concorde and the Tornado.
For an aircraft proposed in 1962 that would be in service in 1970, this aircraft showed most of the thinking behind the Tornado had already been achieved. The project was killed when the government announced it’s intention to order the American Phantom as a stop gap until the introduction of the Hawker P1154 - the supersonic Harrier - an aircraft that was also cancelled.
