The Avco-Lycoming AGT1500 is a gas turbine engine. It is the main powerplant of the M1 Abrams series of tanks. The engine was originally designed and produced by the Lycoming Turbine Engine Division in the Stratford Army Engine Plant. In 1995, production was moved to the Anniston Army Depot in Anniston, Alabama, after the Stratford Army Engine Plant was shut down.

Specifications

Engine output peaks at 1500 hp, with 2750 lbft of torque at that peak, which occurs at 3,000 rpm. The turbine can provide torque in excess of 667 lbft at significantly lower RPMs. The engine weighs approximately 2500 lb and occupies a volume of 40 ft3, measuring 63 ×. The engine can use a variety of fuels, including jet fuel, gasoline, diesel and marine diesel. The engine is a three-shaft machine composed of five sub-modules:

History

Development had started by 1964 with a contract given to Chrysler in 1976, originally as an engine for the later cancelled MBT-70. In the early 1970s, the AGT1500 was developed into the PLT27, a flight-weight turboshaft for use in helicopters. This engine lost to the General Electric GE12 (T700) in three separate competitions to power the UH-60, AH-64, and SH-60. Serial production of the AGT1500 began in 1980; by 1992, more than 11,000 engines had been delivered. In 1986, with the Cold War about to wind down, Textron Lycoming began developing a commercial marine derivative, which they called the TF15.
