Constant Speed 400 Hz Aircraft Electric Generation System 791067

The purpose of this paper is to examine recent innovations in the state-of-the-art of aircraft constant speed drive alternating current electric power generation systems. An engineering problem was posed by the concepts used in designing the latest generation of commercial aircraft. The approach to solving the problem and the solutions chosen have offered the opportunity to further increase the reliability of the aircraft secondary power system. The maintenance required has been decreased by simplifying the system, and much of the error potential involved in fault isolation has been eliminated by a reliable Built-In Test (BITE) system.
