A HORSE POWER MEASUREMENT SYSTEM FOR NEXT GENERATION AIRCRAFT(International Foundation for Telemetering, 2000-10)Understanding the horsepower demands that electrical and hydraulic systems place on an aircraft engine is critical since this directly effects engine performance. The current methods of measuring horsepower have been mainly limited to lower rpm engines and are not suitable for higher rpm jet engines. L-3 Telemetry East has developed instrumentation for the F-22 instrumentation group that is capable of measuring horsepower loads on engine shafts that are rotating at up to 18000RPM. This paper describes the operation of this system.
