Packaging the VSCF System for an Aircraft Engine Environment 811088

This paper addresses the packaging considerations and techniques used in the design of a fully integrated VSCF package which is mounted on an engine accessory gearbox. Special design considerations such as vibration, altitude, and temperature in the gearbox area are discussed. A comparison and description of various methods of cooling, such as cold plate, immersion, and spray within a self contained cooling/lubrication system is also presented. The paper describes the integration of microprocessor modules, high power semiconductor arrays, and a high-speed generator, to form a compact, low weight VSCF system.
