Abstract:

Based on the criteria factors of reliability, weight, volume, ability to meet environment, availability, development and production cost, and growth potential, several types of auxiliary power units were studied for ballistic missile mounted countermeasures systems. These systems include battery powered APU turbine driven, solid propellant powered APU and turbine driven, liquid propellant powered APU. The results, which consider a power-time envelope of 100 to 2000 watts and 2 to 20 minutes duration of operation, show that there is no definite point where it can be stated that one type of system is better than any other. Battery powered systems are competitive with the others for requirements of 500 watts or less and 5 minutes or less duration. Present state-of-the-art does not permit use of a solid propellant powered turbine driven APU beyond a time duration of eight minutes. For power levels above 500 watts and eight minutes operation, present state-of-the-art dictates use of a liquid propelled turbine driven APU. Author
