Integrating a Torque Measurement System for the GE T408 Engine into a CH-47D Chinook

This paper presents an overview of the efforts associated with integrating a new torque measurement system for T408 engines into an NCH-47D airframe and performance of the torque measurement system during operation on the aircraft. The effort described was performed collaboratively between GE Aviation, The Boeing Co, Parker LORD, and DEVCOM AvMC. The Torque Measurement System was utilized in the T408 Engine Control System during its demonstration on an NCH-47D airframe at Ft. Eustis, VA. In addition, based on DEVCOM AvMC program requirements, health monitoring capability was successfully implemented and demonstrated during the NCH-47D T408 Engine Demonstration. Lessons learned from the torque measurement system's health monitoring features are included.
