Cierva C.24

The de Havilland C.24 was a two-seat autogyro built by de Havilland at its Stag Lane works in England in 1931

Design and development

The C.24 was built in 1931 using a Cierva rotor head coupled to the cabin of a de Havilland DH.80A Puss Moth, and driven by a 120 hp Gipsy III engine. It was withdrawn from use by December 1934.
A single example was produced and is part of the Science Museum collection. In 1932, it was redesignated C.26 when a two-blade rotor system was installed. Since 2008 it has been on loan to the de Havilland Aircraft Museum at Salisbury Hall, near London Colney in Hertfordshire. In flight, it had a maximum speed of about.
