The SIAI S.21 was an Italian single-seat racing flying boat produced by SIAI specifically for participation in the 1921 Schneider Trophy competition.
Design and development
This model featured a biplane configuration with the upper wing having a shorter span than the lower wing. Its powerplant was a 224 kilowatts (300 hp) Ansaldo San Giorgio 4E-14 engine, positioned on struts above the hull yet beneath the upper wing, driving a four-bladed propeller arranged in a pusher setup. To enhance stability on water, small floats were attached under each side of the lower wing.
Operational history
Flight testing revealed that the S.21 was notably challenging to pilot. The only aviator to manage it effectively was Guido Jannello, who had previously gained recognition at the 1918 Schneider Trophy flying a Savoia S.13. Unfortunately, when Jannello became ill during the 1921 Schneider Trophy event and could not fly the aircraft, the S.21 was subsequently withdrawn from competition.
Popular culture
- In the Japanese animated movie Porco Rosso, the protagonist’s aircraft is named a Savoia S.21. Nevertheless, its design is inspired by this particular plane but does not closely match the authentic S.21; instead, it bears greater resemblance to the Macchi M.33.
