The CSIR Experimental Autogyro II is a South African two-seat experimental autogyro designed and built by the Aeronautics Research Unit of the Council for Scientific and Industrial Research.[1]
Development
As part of the support to South African aircraft manufacturing industry the ARU developed a single-seat autogyro as a research vehicle.[1] Design of the autogyro was started in 1965 and construction followed in April 1967, by 1972 the autogyro, registered ZS-UGL, was ready for tethered tests mounted on a lorry-platform, it made its first free flight on 30 November 1972 at Swartkop Air Force Base.[1] Following the test flights the autogyro was modified.[1]
Design
The autogyro had a box-like fuselage structure made from light-alloy and was fitted with twin fins and rudders with a fixed incidence tailplane mounted between them.[1] It was fitted with a two-bladed teetering rotor, the rotor could be spun up using a shaft drive through a clutch from the engine.[1] The engine located at the rear was a 180 hp (134 kW) Continental O-360-A air-cooled engine driving a two-bladed constant-speed pusher propeller.[1] The crew sat side by side in the enclosed fuselage with dual controls, entrance is through a forward-opening glazed door on each side.[1] The landing gear was a fixed tricycle type with a self-centering and steerable nosewheel.[1]
