In the 1930s, Lycoming made a number of attempts to develop successful high-power aircraft engines. The 1 200 hp (895 kW) O-1230 was Lycoming's attempt to produce an engine based on the United States Army Air Corps hyper engine concept, and used a variety of features to produce nearly 1 hp/ in 3 (46 kW/L) of engine displacement .
1955–present. Developed into. Lycoming IO-390. Lycoming O-540. Lycoming IO-720. The Lycoming O-360 is a family of four-cylinder, direct-drive, horizontally opposed, air-cooled, piston aircraft engines. Engines in the O-360 series produce between 145 and 225 horsepower (109 to 168 kW), with the basic O-360 producing 180 horsepower. [1]
The IO-390 family of engines, which Lycoming refers to as the IO-390-X, produce 200 hp (149 kW) to 215 hp (160 kW). The IO-390 was developed from the similar IO-360 engine, by using cylinders from the IO-580 [citation needed] to increase the O-360's cylinder bore. (Although the IO-390 cylinder assembly [ 4 ] is not the same part number as the ...
Lycoming O-435. The Lycoming O-290 is a dual ignition, four-cylinder, air-cooled, horizontally opposed aircraft engine. It was first run in 1939, and entered production three years later. A common variant of the type is the O-290-G, a single ignition model which was designed to drive a generator as part of a ground power unit.
The Lycoming O-320 is a large family of naturally aspirated, 320 cu in (5.2 L) air-cooled, horizontally-opposed four-cylinder, direct-drive engines produced by Lycoming Engines. Introduced in 1953, it is commonly used on light aircraft such as the Cessna 172 and Piper Cherokee , and remains in production as of 2024.
Produced. 1957–present. Developed from. Lycoming O-360. The Lycoming O-540 is a family of air-cooled six-cylinder, horizontally opposed fixed-wing aircraft and helicopter engines of 541.5 cubic inches (8,874 cc) displacement, manufactured by Lycoming Engines. The engine is a six-cylinder version of the four-cylinder Lycoming O-360.
The type certification for the P.68 Victor, a twin piston engine, high wing monoplane with fixed tricycle landing gear was applied for on 22 January 1969. [2] The Partenavia P.68 was designed as a six-seat light transport and trainer powered by two 200 hp (149 kW) Lycoming IO-360 engines, it made its first flight on 25 May 1970 at Naples. [1]
