A 40-Kva 400-Cycle Aircraft Alternator

A-c auxiliary-power systems for aircraft date back to World War I. Recently numerous technical articles have indicated an intense revival of interest in this subject. Heart of any electric system is the generator which supplies electric power to all parts of the system. An alternator, especially designed and built for 208-volt three-phase systems is described in this paper. Light weight and reliability dominate the design, which involved a large number of new and unusual problems.
