Garrett Engine Division of Allied-Signal Aerospace, Inc., which supplies small-to-medium size gas turbine propulsion engines to the fixed-wing aviation market, is expanding its product line to include the small-to-medium turboshaft engine for the rotary wing (helicopter) aviation market. The recent win of the T800-LHT-800 down-select formed a firm foundation for this expansion. Garrett is developing the T800 in a partnership with the Allison Gas Turbine Division of General Motors Corporation, under the company name of Light Helicopter Turbine Engine Company (LHTEC). The T800 turboshaft engine (1300-shp, 1000-kW class), which has superior performance in this power class (10 to 30 percent better specific fuel consumption and power-to-weight than current production turboshaft engines), is designed to power the U.S. Army's LHX light attack helicopter. Garrett is pursuing complementary technologies focused on serving a full spectrum of turboshaft engine requirements for the 1990s and beyond. Garrett is also teamed with General Electric Aircraft Engines (GEAE), for the Joint Turbine Advanced Gas Generator (JTAGG) demonstrator program. JTAGG supports the Integrated High Performance Turbine Engine Technology (HPTET) initiative of doubling propulsion system capabilities by the year 2003. New technologies incorporated in the T800, and emerging technologies and concepts applicable to future turboshafts, are discussed.
