Honeywell ALF 502 on a BAe 146
Lycoming ALF 502 is a geared turbofan engine produced by Lycoming, AlliedSignal and then Honeywell Aerospace.
Development [ edit ]
The original YF102 was developed at the
Lycoming Turbine Engine Division in Stratford, Connecticut by adding a fan to the Lycoming T55 engine, which was used as the gas generator. Six engines were built for the [1 ] Northrop YA-9 prototype ground-attack aircraft. These engines were later reused in the C-8A Quiet Short-Haul Research Aircraft (QSRA).
The ALF 502 was certified in 1980, and used on the
British Aerospace 146 and Bombardier Challenger 600. The improved, higher-thrust LF 507 was used on the Avro RJ update of the BAe 146.
