LeBlond radial engines

The LeBlond radial engines were a family of 5-cylinder and 7-cylinder, air-cooled radial engines for aircraft, built in the 1930s by the LeBlond Aircraft Engine Corporation.

Variants

LeBlond 60-5D
Introduced in 1928, the 60-5D was a 60 hp (45 kw) 5-cylinder, air-cooled, radial piston engine with a displacement of 234 cuin (3.8 l). This model used iron cylinder heads and was a direct development of the Detroit Air Cat.
LeBlond 70-5DE
Introduced in 1930, the 70-5F was a 70 hp (52 kw) at 1,950 rpm 5-cylinder, air-cooled, radial piston engine, (4.125 x 3.75 = 250.57 cuin (4.11 l)), using iron cylinder heads and two bearings.
LeBlond 85-5DF
Introduced in 1930, the 85-5F was an 85 hp (63 kw) at 1,975 rpm 5-cylinder, air-cooled, radial piston engine, (4.25 x 3.75 = 265.99 (4.36 l)), using aluminum cylinder heads and three bearings.
LeBlond 70-5E
Introduced in 1930, the 70-5E was a 70 hp (52 kw) 5-cylinder, air-cooled, radial piston engine. Production of the 5E continued in production under Ken-Royce as the Rearwin Ken-Royce 5E.
LeBlond 80-5F
Introduced in 1930, the 80-5F was an 80 hp (60 kw) 5-cylinder, air-cooled, radial piston engine with a displacement of 266 cubic inches (4.4 litres) Using three bearings as developed for the earlier 5DF series, the LeBlond 5F was introduced in 1930. When aircraft powered with the 5F were commandeered by the U.S. Army, the engine was re-designated the R-265. This engine was the last of the so-called 'greasers'. Production of the 5F continued under Ken-Royce as the Rearwin Ken-Royce 5G.
LeBlond 85-5DF
Introduced in 1930, the 85-5F was an 85 hp (63 kw) 5-cylinder, air-cooled, radial piston engine with a displacement of 266 cubic inches (4.4 litres)
LeBlond 90-5F
Introduced in 1930, the 90-5F was a 90 hp (68 kw) 5-cylinder, air-cooled, radial piston engine with a displacement of 266 cubic inches (4.4 litres)
LeBlond 90-5G
Introduced in 1930, the 90-5G was a 90 hp (68 kw) 5-cylinder, air-cooled, radial piston engine with a displacement of 266 cubic inches (4.4 litres) Production of the 5G continued under Ken-Royce as the Rearwin Ken-Royce 5G.
LeBlond 90-7D
90 hp (67.1 kW) at 1,975rpm 4.125 x 3.75 = 350.81 cu in (5.75 L)
LeBlond 110-7DF
110 hp (82.1 kW) at 2,150rpm 4.25 x 3.75 = 372.39 cu in (6.10 L) (Rearwin (Ken-Royce) after 1937)
LeBlond 120-7
