Collection Item Summary:

In 1911, with their assistant Charles Taylor, Wilber and Orville Wright’s original Wright Company began work on a six-cylinder engine, which was first used by the U.S. Army Signal Corps on the Wright Model C aircraft. The engine developed problems in service, leading to design changes, and by 1913 a modified engine known as the Wright 6-60 evolved. At 1560 rpm, it was claimed that this engine developed 53.6 to 55.9 kW (72 to 75 hp). In 1914, a flexible flywheel drive was added, and the engine was re-designated Wright 6-70.

This engine, manufacturer's serial number 11, was one of the first six-cylinder engines designed and built by the Wright Company. One of the earliest Wright six-cylinder engines was installed in the U.S. Army Signal Corps aircraft Number 10 at Fort Riley, Kansas.
