Abstract : A method is presented for, evaluating four possible types of aircraft accessory power transmission systems as listed below. 1. Pneumatic 2. Hydraulic 3. Electric 4. Mechanical This evaluation method is intended for use in deciding which type of accessory transmission system should be used in a given type aircraft. These systems were analyzed on a minimum weight basis. Weights as well as the increase in fuel weight to compensate for power extracted from the engines were considered on the basis of mission profile and power characteristics of the accessory systems. The minimum weight was mainly determined by the transmission line sizes in the respective systems, while other components were essentially constants in the analysis.
