From Wikipedia, the free encyclopedia
Lawrance Aero Engine Company was an American aircraft engine manufacturer. Founded by engine pioneer Charles Lawrance, it designed one of the first successful air-cooled radial engines. It only existed for 5 years, being acquired by Wright Aeronautical, a much larger company better able to mass produce Lawrance's radial engines.
History
The Lawrance Aero Engine Company was founded in 1917.[1] After the end of World War I, the Lawrance engineers worked with both the Army and the Navy in developing their L-1 into a nine-cylinder radial engine, which became the 200 hp Lawrance J-1. It was the best American air-cooled engine at the time, and passed its 50-hour test in 1922.[2]
The United States Navy was very enthusiastic about air-cooled radials, but was concerned that Lawrance couldn't produce enough engines for its needs. The Navy suggested to Wright that it purchase the Lawrance company and build the J-1 itself. In May 1923, Lawrance was purchased by Wright Aeronautical, with the J-1 being further developed by Wright into the J-5, J-6, and R-795.[3]
