Penrose Pegasus
The Penrose Pegasus was a 1930s high-wing, single-seat, wooden glider from the UK. Designed, built and flown by Harald Penrose until the start of World War II, only one was built at the time though a reproduction was constructed in the 1990s.
==Design and development==
In 1932 Penrose, Chief Test Pilot at Westland Aircraft from 1931–53,〔 began the design of a wooden single-seat glider. One unusual design constraint was that no component could be more the 12 ft 6 in (3.81 m) long in order for it to leave the workshop.〔
The wing of the Pegasus had the same spar and planform as the unbuilt Cloudcraft Junior. It was constructed around a single box spar of spruce and plywood and had three sections, a parallel-chord centre section and two slightly longer, tapered outer panels with ailerons along the whole of their trailing edges. It was fabric covered and braced with lift struts to the lower fuselage longerons. Both rudder and elevator were all-moving surfaces, fabric covered and with rounded trailing edges. The rudder extended to the lower fuselage so the elevator, mounted on the upper fuselage, had a cut-out to allow its movement.〔〔
The Pegasus had a rectangular-section, ply-covered fuselage, which tapered towards the tail. The wing was braced above the fuselage by the struts and the open, unscreened cockpit was under the leading edge; fabric-covered, inverted V-shaped decking tapered from the lower wing surface rearwards. There was a short, curved landing skid fixed at the nose and joined to the lower longerons at the same point as the lift struts by a V-form pair of telescopic compression struts. Initially the Pegasus had a tailskid but flight trials showed that both skids were easily broken, so the main skid was replaced with a stiffer one and the tailskid by a rubber tailwheel.〔〔
