The Determination of Thermal Characteristics of Standard Type Naval Airborne Generators

Abstract

A study of the loading of aircraft generators indicates that loads of short duration but of high magnitude occur. In order to be able to recommend, with reasonable accuracy, the power generation system for an aircraft, it is necessary to know the thermal characteristics of the generators as well as the type of loading to be expected. Studies were made to determine these characteristic curves for several standard aircraft generators. The results of this investigation indicate that the brushes will, to a large extent, govern the magnitude and duration of the overload which a generator can safely stand. This is due to the high initial rate of rise of the temperature of the brushes, as compared with that of other parts of the generator.
