Problems are encountered in the determination of in-flight power of turboprop engines which are not fitted with a direct torque measuring device. Elaborate investigations were carried out on such an engine to estimate its performance during its service with fleet. The present paper describes the special tests and their results to determine the effectiveness of water methanol injection, nature of installed loss and torque shift. Based on the above information a procedure is presented for the estimation of in-flight engine power. The contents of this paper would be of great interest to the operators of such engines and to the designers and manufacturers in the assessment of the overall flight performance of the aircraft fitted with such engines.
