Secondary Power Supplies for a Small Single Engined Combat Aircraft,
Abstract
This paper describes a possible secondary power supply system for a small single-engined combat aircraft. It describes the way in which reliability, survivability and installation problems influence the type of system which is proposed for such an aircraft. The particular constraints imposed by the use of a Pegasus vectored thrust engine in a Short Take Off Vertical Landing (STOVL) aircraft are also discussed. The proposed system consists of a conventional engine-driven accessory gearbox to provide hydraulic and electrical power in flight. A remotely mounted APU is used to start the engine by means of a pneumatic link from a load compressor. The APU drives a separate standby hydraulic pump and generator for ground operation and emergency power in flight. Possible areas of future research and development which would lead to improved efficiency and reduced weight are also discussed. (Author)
