The Garrett Auxiliary Power Division's Multipurpose Small Power Unit (MPSPU), Contract DAAJ02-86-C-0006, sponsored by the Aviation Applied Technology Directorate, Ft. Eustis, Virginia, has progressed through detail design and analysis to component and power unit development testing. The MPSPU Advanced Development program is structured to provide advanced technology for current and future United States Army and other Department of Defense auxiliary power unit/secondary power system applications for aircraft, combat vehicles, and mobile tactical shelters. The MPSPU has been designed for low specific fuel consumption, low weight and volume, low acquisition and life cycle costs and high reliability and durability.
