The Heinkel HE 57 was an amphibious flying boat powered by a single engine, constructed in 1929.
Development
Only one HE 57 was produced by Heinkel's Ernst-Heinkel-Flugzeugwerken facility located in Warnemunde during 1929.[1] It made its public debut at the Paris Aero Show in December 1930 and was later exhibited at the Stockholm International Aero Show in May 1931.[2] Subsequently, the aircraft was acquired by a flight training school based in List auf Sylt, where it served as a trainer.[1]
Design
The hull featured a double-stepped design crafted from aluminum. Its wings incorporated wooden spars combined with aluminum ribs, all covered with fabric.[2] The landing gear was designed to retract hydraulically, operated by a manual pump.
