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. This paper discusses the design and current developmental status of the Garrett GTP50 MPSPU as reported by Kidwell (1988).

The Multipurpose Small Power Unit (MPSPU) Advanced Development Program is providing the United States Army and other Department of Defense branches with advanced technology for current and future auxiliary power units (APUs)/secondary power systems (SPSs) in aircraft, combat vehicles, and mobile shelters. The design includes low specific fuel consumption (SFC), weight and volume, acquisition and life cycle costs (LCC), and high reliability and durability. The Garrett Auxiliary Power Division (GAPD) Model GTP50-1 MPSPU has demonstrated major advances in small gas turbine power unit design and manufacturing technologies. Component test rigs have completed extensive development testing. Power unit operation of 214 hours, with 557 starts, has been accumulated. Power unit and rig testing has demonstrated program goals and identified areas for continued technical development. The program has demonstrated 77.6 kW (104 shp), corrected to sea level standard day, at an SFC of 0.5 kg/kW-hr (0.8 lb/hp-hr).

The oilless, gearless and bleedable under armor auxiliary power unit (UAAPU) development program is providing the United States Army with a technically advanced auxiliary power unit (APU) for military tracked vehicles. Fully functional prototypes in two configurations are being demonstrated in both laboratory and field tests. The APU power output is 32 kw (43 shp) with 10 to 20 kw supplied as electrical power and the balance of power delivered as elevated pressure bleed air for use in conjunction with the vehicle nuclear, biological, and chemical (NBC) filtration and environmental control system (ECS). The design of the UAAPU incorporates air bearings and a shaft-speed permanent-magnet starter/generator with electronic power conditioning to eliminate completely the need for oil lubrication and an auxiliary gearbox. This significantly simplifies the mechanical design of the APU with resulting reliability, durability, and maintainability improvements. Over 600 hours of laboratory system development test time has been logged and 90 hours in field tests on an M1A1 main battle tank. Operations in the field have included both gunnery and simulated warfare training exercises.

The Garrett GTCP36-300 Series Auxiliary Power Unit is being developed for use on advanced technology transport aircraft in the 150-passenger size class. The first application will be the Airbus Industries A320 Aircraft. The APU uses a 6:1 pressure ratio, single-stage compressor and turbine, driving a single-stage load compressor and accessory gearbox. The 480 horsepower APU delivers compressed air to the aircraft pneumatic system and drives a customer furnished 90 kva, 24,000 rpm electrical generator. State-of-the-art aerodynamics, materials, and digital electronics are used to give the user-airlines an APU delivering maximum performance with minimum envelope, weight, and cost of ownership.

Technology Demonstrator

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.

An advanced technology small gas turbine program is being sponsored by the U.S. Army to complete the design, fabrication, and test of the T-100 Multipurpose Small Power Unit (MPSPU). This paper describes the basic design features and current development status of the T-100. This small gas turbine power unit is designed for airborne, vehicular, and ground auxiliary power applications at low cost. The T-100 design incorporates the most current aerothermodynamic and structural component technologies with extensive small turbomachinery and combustor experience gained from a similar class gas turbine two decades ago. The T-100 design, fabrication, and component rig testing of the Inlet Protection System (IPS) compressor, combustor and turbine have been successfully completed. Engine testing is now in progress on the 50 HP (37.4 kw) rated unit.

New Generation

In response to the need of the new generation of commuter airliners, General Electric has developed the CT7 Turboprop engine so that it may be used as an Auxiliary Power Unit (APU) in addition to its normal mission as a prime propulsion unit. The General Electric CT7 Turboprop is a 1700 shaft horsepower class engine (Figure 1) developed for the new generation of 30+ passenger commuter and executive aircraft(1). Beyond this, the CT7 engine now offers the airlines a self-contained APU system to provide bleed air for the Environmental Control System (ECS) and electrical power for the aircraft during ground operation. This negates the need for a separate on-board APU with its extra cost, weight and fuel consumption and also eliminates the requirements for ground power units at the airlines’ operational terminals. The development of the engine as an APU generated a new set of technical requirements for the design and development and necessitated the development of special certification requirements as this was a new and unique operating condition for an aircraft prime propulsion system. A propeller brake had to be developed to lock the propeller and power turbine system and the engine had to be designed to operate at or near idle while producing large amounts of bleed air and electrical power. This development program was successfully completed in mid-1985 with the certification of the aircraft to operate with the CT7 Turboprop engine running as an APU.
