Conversion of small tutbomachinery advanced technology from USA Department of Defense to commercial markets of opportunity is discussed in the light of recent development of the T-100 Multipurpose Small Power Unit (MPSPU) for the U.S. Army.

For the power class from 50 SHP to 75 SHP (37 KW to 56 KW), the small T-100 MPSPU Gas Turbine represents a milestone in achieved simple-cycle non-heat-exchanged thermal efficiency. Application of this turbomachinery technology, and in combination with heat recovery to compact turboalternator systems, is a prime candidate for conversion from airborne/defense use only to defense/commercial and airborne/ground implementation.

The T-100 MPSPU Test Program achievements are summarized in this paper. Also, preliminary design/off-design studies are presented for a turboalternator based on T-100 MPSPU components, and a scaled derivative that would achieve 60 KWe at modest turbine inlet temperature is presented. The turboalternator design objective is to provide a reliable compact source of electric power for military and commercial use in stationary, vehicular and aircraft applications that will run on most fuels, with low initial and operating costs, runs quietly, has low emissions and provides good to excellent specific fuel consumption.
