Gas turbine engine carcass is one of the major structures that supports/houses the main engine rotors, stator blade rings, interface features to mount the engine onto the airframe and accessories, viz., gearbox, electronic control units, pipelines, actuators, and so on. All the reaction forces generated by the engine are finally grounded to the airframe through this engine carcass. Specific to aero engines, designers make every effort to reduce the weight of this engine carcass so as to maximize thrust to weight ratio of the engine while maintaining the stiffness requirement. The present paper deals with an integrated approach for health assessment of the engine carcass. The theoretical and experimental studies undertaken for the engine carcass and rotor for enhancing the diagnostic reliability have been put forward. The requisite instrumentation and signal processing to assess the health have also been included. The decision-making for furthering of the test and remedial measures are also brought out.
