Aircraft Background Edit
The 545 addressed the Swift’s stability problems with a cranked wing layout. Experience had shown that highly swept wings lead to the early onset of stalling at the wing-tips. The 545 wing therefore reduced over it’s sweep from 50 degrees at the root to 30 degrees at the tip.
In January 1952, the go-ahead was given for the production of a single 545. In 1954 the more powerful RB.106 was available, and this increased the planned top speed of the 545 from mach 0.97 to mach 1.3-1.7. Supermarine progressed the programme, known as the ‘Supersonic Swift’, along these lines and presented their plans for the higher speed 545.
Upon reflection, the air ministry got concerned at pressing ahead with an aircraft that would approach mach 2 without the experience on mach 2 flight. They rightly assessed that mach 2 performance was more complex than a modified wing and a larger engine.
The 545 never took to the air as the programme was terminated when the aircraft was half built. Mach 1+ experience was being achieved with the Fairey Delta II and the English Electric Lightning. However, in order to better understand mach 2 flight, the ministry created ER.143 for which Vickers-Supermarine proposed the 553.
