The LeBlond radial engines, later produced under the name Ken-Royce, were a family of 3-cylinder, 5-cylinder and 7-cylinder, air-cooled radial engines for aircraft, built in the 1930s by the
LeBlond Aircraft Engine Corporation until the operation was sold to
Rearwin Airplanes in 1937 and renamed Ken-Royce Engines.
