The Sikorsky S-19 was a Russian twin engine experimental prototype aircraft built late in 1916 by the Russian Baltic Railroad Car Works while Igor Sikorsky was head of the aviation division.

Design and development

The S-19 was a two bay sesquiplane powered by two 150 horsepower (112 kilowatts) Sunbeam Crusader water-cooled V-8 engines installed in push-pull configuration. Arranged as a Twin-boom aircraft, it had a large rudder located in the center of the empenage. Two crewmembers occupied cockpits in the foreword most section of the booms just forward of the lower wing and served as pilot and machine gunner.

The S-19 had two 150hp Sunbeam engines in tandem and a cockpit in the nose of each of the twin tailbooms that projected slightly forward of the lower wings. The design seems to have emanated from the Russian War Department, which ordered the RBVZ to match German experiments with twin-boom combat aircraft. The prototype was completed in late 1916.

Experimental twin-fuselage aircraft built by the order of Military Department. Its military function was uncertain and the only built prototype was not armed. Two engines were installed on the lower wing in tandem. Large rudder was installed in the center of the tail plane.

Aircraft was built, tested. Once it did not demonstrated exceptional performance, after minor crash it was abandoned.
