ROTARY ENGINE. Revolutionary advancement in automotive engineering. The rotary engine was an early type of internal-combustion engine in which the crankshaft remained stationary and the entire cylinder block rotated around it. The design was used mostly in the years shortly before and during WORLD WAR I to power aircraft, and also saw use in a few early motorcycle races or in off-road conditions.
By the early 1930s the rotary aircraft engine was becoming obsolete, mainly because of a limit to its possible output torque which was a consequence of the way the engine worked. The ADAMS COMPANY built a successful rotary engine. The design was originated by Fay Oliver FARWELL in 1896.
The Adams-Farwell rotary engine was being manufactured for use in automobiles by 1901. Emil Berliner also sponsored the development of the Adams-Farwell engine as a power unit for his helicopter experiments. The engine was extremely light and was ideal for vertical flight. Designed and built by the Adams Company of Dubuque, Iowa, in 1907, this engine powered three, man-lifting experimental helicopters. Two of these helicopters were designed by Emile Berliner and flown in 1909 and 1910. The third was designed by J. Newton Williams and flown in 1909.
Adams-Farwell engines later powered fixed-wing aircraft in the United States after 1910. It has been claimed that the Gnôme design of the French was patterned from the Adams-Farwell; an Adams-Farwell car was reported to have been demonstrated to the French Army in 1904. Unlike the later Gnôme engines, the Adams-Farwell rotaries had exhaust and inlet valves mounted in the cylinder heads.
