The report is a study program to define and evaluate auxiliary power systems for a 1975 V/STOL fighter aircraft with a given mission profile. Many of the results of this study are generally applicable to other types of aircraft. The mission and auxiliary power requirements for a typical V/STOL fighter aircraft were defined by the Air Force and from information received from the airframe industry. Thirty-seven candidate systems which involved 184 options are identified and the vertical-takeoff gross-weight penalty associated with each are given for both long- and short-time aircraft standby periods. The components of the various systems are evaluated as to their projected (1975) efficiency, weight, and size and these projected values were used in the system analyses. A recommended reference system was selected as the basis for an optimized system design. Recommended research and development programs which are necessary to obtain the projected 1975 system components are delineated with the estimated man-hours and cost required. An estimate of the possible gains is included. Included in the report is an estimate of the state-of-the-art of auxiliary power system components. For comparison purposes, the takeoff gross-weight penalties of selected systems were calculated for state-of-the-art components. (Author)
