Product Code:SAE AIR1087
Title:Aircraft Accessory Drag Torque During Engine Starts
Issuing Committee:Ae-6 Starting Systems And Auxiliary Power Committee
Scope:The purpose of this Aerospace Information Report is to present a brief discussion of the drag torques of aircraft accessories operating at cold temperatures, specifically -65掳F. The parameters affecting the magnitude of torque at various speeds and acceleration rates are reviewed. In conclusion, this report establishes the difference in accessory torque characteristics that are obtained by various test procedures and recognizes the need for a standard test method.
