Armstrong Siddeley Hyena

Armstrong Siddeley Hyena was the name of the British manufacturer Armstrong Siddeley, which was intended for use in military and civil aviation of a piston aircraft engine.

The 1933 introduced air-cooled 15 -cylinder triple radial engine was tentatively incorporated into the fighter Armstrong Whitworth AW16 ( registration G - ABKF ). The aircraft was awarded a special engine cover, which in its size had five variable air inlet openings. The first flight on 24 October 1933 and the subsequent testing completed, the then chief pilot Charles Turner Hughes. It was originally planned to install the engine in two further samples. Firstly, in the single-seat fighter Armstrong Whitworth AW28 and the other in the two-seat multi-purpose aircraft Armstrong Whitworth AW37. Since series production was omitted, because the problem of cooling the rear star could not be satisfactorily resolved, the engine remained practically without further use.

Three star motor were not added after the other and arranged so that each three cylinders standing in a row. Despite a built- in support of the cooling fan, this was insufficient. To drive the propeller, the engine had a planetary reduction gear.
