Optimization Study Missile Auxiliary Power Systems (as viewed by the equipment supplier) 590036
VARIOUS energy sources applying to self-sufficient power units for aircraft and missiles using ramjet and/or rocker powerplants are discussed in this paper. Most of the systems mentioned require a 5-20 hp hydraulic supply and enough electrical energy for durations up to 1 ½ hr.
Within the limitations of this study the flywheel system has been shown to have some surprising weight advantages for durations up to 1–2 min. The reciprocating engine powered by hot propellant gas, or by air fuel, is lighter for longer durations. Monopropellant turbines and silver-zinc cells powering electrical motorpumps are generally competitive on a weight basis for the intermediate durations.
The authors also discuss several types of power conversion units: hydraulic, alternator and d-c motors, turbines, hot-gas servo systems, and invertors.
