The Cierva C.8 was an experimental autogyro built by Juan de la Cierva in England in 1926 in association with Avro. Like Cierva's earlier autogyros the C.8s were based on existing fixed-wing aircraft fuselages - in this case Avro 552s. The first example the C.8R (known to Avro as the Type 587) was a rebuild of the C.6D fitted with stub wings and paddle-shaped main rotor blades.
Made by Juan de la Cierva.
