Advanced Technology Programs for Small Turboshaft Engines: Past, Present, Future

This paper addresses approximately 15 years of advanced technology programs sponsored by the United States Army Aviation Applied Technology Directorate and its predecessor organizations and conducted by GE Aircraft Engines (GEAE). Included in these programs is the accomplishment of (1) the 1,500 shp demonstrator (GE12) which led to the T700, and (2) the 5,000 shp Modern Technology Demonstrator Engine (MTDE/GE27). Also included are several advanced technology component programs which have been completed or are ongoing through the early 1990’s. The goals for the next generation of tri-service small advanced gas generator demonstration programs are shown. A prediction is thus made of the advancements required to fulfill the aircraft propulsion system established by the DoD/NASA Integrated High Performance Turbine Engine Technology (IHPTET) initiative through the year 2000.
