INVESTIGATION OF CONTACTLESS SWITCHING CONCEPTS FOR APPLICATION TO AIRCRAFT ELECTRICAL SYSTEMS VOLUME Ⅱ CONCEPT DESIGN STUDIES

摘要

A study program was conducted to establish and evaluate contactless switching design techniques for application to aircraft electrical systems. Design concepts utilizing semiconductor devices were investigated to provide an effective and reliable aircraft electrical power switching and control system. Typical circuits have been designed that will perform the functions of conventional switches, relays and circuit breakers, including switching and control of the primary bus. Breadboards have been constructed and operated to verify the anticipated design performance. Mechanical design characteristics are discussed for the signal sources, control logic and power contacts. Aircraft system design technique are discussed from the aircraft systems designer’s viewpoint, and a preliminary reliability analysis is presented.
