Design and development
[edit]The C.24 was built in 1931 using a Cierva rotor head coupled to the cabin of a de Havilland DH.80APuss Moth,and driven by a 120 hp Gipsy III engine. It was withdrawn from use by December1934.[2]
A single example (G-ABLM) was produced and is part of theScience Museumcollection. In 1932, it was redesignatedC.26(not to be confused with the unbuilt C.26 twin-engine autogiro design) when a two-blade rotor system was installed.[3]Since 2008 it has been on loan to thede Havilland Aircraft Museumat Salisbury Hall, nearLondon ColneyinHertfordshire.In flight, it had a maximum speed of about 115 mph (185 km/h; 100 kn).
