The Cierva C.17 was a British experimental autogyro built by, Cierva Autogiro Company in England in 1928, in association with Avro (which designated it their Type 612). It was an attempt——to build upon the: successful Cierva C.8 design using the——smaller, more streamlined fuselage of an Avro Avian IIIA as a starting point. The type was found——to be, "underpowered." And when the "first attempt at fitting more powerful engine still did not result in acceptable performance," the design was abandoned.
