This photo gives a feel of the relative sizes of the Flying Bedstead and SC1:
The SC1 was a VTOL research aircraft powered by five Rolls-Royce RB.108 turbojets (four for lift, one for propulsion). Two aircraft were built The first SC-1 (
XG900) was used until 1971 for VTOL research and is now part of the Science Museum's aircraft collection at South Kensington, London. The second SC-1 (
XG905) can be seen at the Flight Experience exhibit at the Ulster Folk and Transport Museum, Cultra, Northern Ireland
Dimensions Span, 23ft 6in; length from face of nose to rudder trailing edge, 24ft 5in; length over nose probe, approximately 29ft 10in; height from belly to fin tip, 8ft 2.5in; height to fin tip from ground, 9ft 10in (main gear forwards) or 10ft 8in (gear aft); wheelbase, 8ft 1.5in (gear forwards) or about 9ft (gear aft); track, 11ft 6in; axial distance between pitch jet nozzles, 22ft 7.8in; distance from centreline to roll nozzles, 8ft 9.14in.
Areas Wing, gross (apexed), 211.5 sq ft; wing, net, 141.9; elevators (aft of hinge). 14.76; ailerons (aft of hinge), 8.55; fin and rudder, gross, 28.64; fin and rudder, net, 11.63; rudder (aft of hinge), 4.44.
Empty weight: 6,260 pounds
Loaded weight (CTOL): 8,050 lb with "comprehensive test equipment and instrumentation"
Loaded weight (VTOL): 7,700 lb
Performance Maximum speed: 246 mph
Range: 150 miles
Service ceiling: 8,000 ft
Rate of climb: 700 ft/min The thrust of the Rolls-Royce RB.108s installed in the aircraft is given as 2,130lb, suggesting that the maximum lift available from the lift engines is 8,5201b.
