Small Turbine Advanced Gas Generator for Future Propulsion Requirements 720831

On Nov. 30, 1971, the Eustis Directorate of the U.S. Army Air Mobility Research and Development Laboratory issued four contracts for the design, fabrication, and testing of the Small Turbine Advanced Gas Generator (STAGG). The STAGG airflow range is approximately 1-5 lb/s. The purpose of the STAGG program is to provide the core gas generator technology base for future small gas turbine engine programs for the Department of Defense (DOD) as well as the Army. The STAGG program will incorporate advanced component technology into a gas generator in order to define matching and integration problems at an early date, thereby reducing gas turbine engine development time and cost.
STAGG is a core gas generator (gas producer) with the compressor, combustor, turbine, and bearings and seals as prime interest areas. It includes laboratory (slave) inlet, exhaust nozzle, lubrication system, and fuel control system necessary for operation and testing. Two contracts are in the 1-2 and two contracts are in the 3-5 lb/s airflow size. The gas generators will not include accessory drive or power turbine systems.
