Avco Lycoming's ALF 502 High Bypass Fan Engine

The factors influencing the design of the ALF502 engine and the evolution and development status of Lycoming's turbofan engine were the subjects of a paper presented to the Society in San Diego on October 1972.

We study herein today's ALF502 and its selection as the engine to power the latest corporate business jet aircraft and to power a new short haul commuter aircraft. A description of the engine is presented and the modular concept of the ALF502 is addressed.
