The Sikorsky S-34 was a mid-1920s built six-seat amphibious aircraft by the US manufacturer Sikorsky Manufacturing Co. It was the first flying boat or amphibious aircraft designed by Sikorsky, of which only one copy was made.
history
The S-34 was completed in November 1926 and was given the registration number (N) X883. The usual structural design of flying boats at this time was the double-decker design , while Sikorsky designed a high-decker whose wing was attached to the fuselage with struts. Another innovation was the wing stub used instead of support floats on both sides of the fuselage and a landing gear that could be folded against the fuselage. The two Wright J-4 engines sat on the top of the wing. With the S-34, Sikorsky also introduced the tubular stern carrier with a double tail, which is characteristic of all early Sikorsky flying boats and extends from the wing and is supported against the fuselage .
The S-34 was already lost on its first flight due to engine problems when it sank after a ditching. The pilot Collier and Igor Sikorsky, who was on board as an observer, were saved. Sikorsky developed the design and introduced the S-36 a few months later .
