TheCierva C.17was a British experimentalautogyrobuilt byCierva Autogiro Companyin England in 1928, in association withAvro(which designated it theirType 612). It was an attempt to build upon the successfulCierva C.8design using the smaller, more streamlined fuselage of anAvro AvianIIIA as a starting point. The type was found to be underpowered, and when the first attempt at fitting a more powerful engine still did not result in acceptable performance, the design was abandoned.[1]
