The purpose of the investigation was to determine the feasibility of developing a method to predict, with an accuracy of better than plus or minus 1, the maximum power which can be produced by a helicopter gas turbine engine at full-power conditions. The prediction was to be made using information obtained from the engine while the engine was operated prior to lift-off at a partial-power condition of no more than 30 of normal rated power. The prediction method was to be capable of identifying the changes in maximum engine power available due to all possible types of engine deterioration and all ambient conditions. The study was based on a Lycoming T53-L13 gas turbine engine currently being used in Army UH-1 helicopter.
