Development of T-100 Multipurpose Small Power Unit

Abstract

The T-100 Multipurpose Small Power Unit (MPSPU) is a small gas turbine power unit technology demonstrator. Funding has been provided by the U. S. Army for development and test demonstration of this unit. The T-100 integrates emerging component technologies into a single power unit. The technology is targeted for use in airborne, vehicular, and ground auxiliary power applications. Three power levels will be demonstrated with a family of engines derived from the baseline 50-horsepower (HP) unit and include a modified 75-HP unit and two advanced technology versions of the Uprated 100-HP unit. The T-100 MPSPU program approach was to develop advanced component concepts with analyses and rig tests to determine total system performance in the MPSPU power units. The results of this process are summarized here. Component rig tests included the inlet protection system, compressor stage, combustor, and turbine stage. These rig tests demonstrated advances in component capabilities for small turbomachinery. Power unit testing has demonstrated achievable levels in specific fuel consumption (SFC) and overall performance for a gas turbine power unit in this class.
