Sikorsky S-7 Sikorsky S-7 The Sikorsky S-7 was a Russian single engine experimental prototype aircraft built by the Russian Baltic Railroad Car Works shortly after Igor Sikorsky became chief engineer of the aircraft manufacturing division. The S-7 was two place wire-braced monoplane powered by a Gnome air-cooled rotary engine. Construction began in early summer of 1912 and completed in July.
