de Havilland - Cierva C.24


The de Havilland C.24 was a two seat autogiro built by de Havilland at its Stag Lane works in England in 1931, using a Cierva rotor head coupled to the cabin of a de Havilland DH.80A Puss Moth, and driven by a 120hp Gipsy III engine. It was withdrawn from use by December 1934.
A single example (G-ABLM) was produced and is part of the Science Museum collection. In 2008 it was on loan to the Mosquito Aircraft Museum at Salisbury Hall, near London Colney in Hertfordshire. In flight, it had a maximum speed of approx 105 knots.

In 1932 the C.24 was redesignated C.26 when the three-blade rotor system was replaced by a two-blade rotor, though not to be confused with an unrelated design study sharing the same designation.
