Many aspects of engine/airframe coupling which are related to structures are examined. The generation and analysis is studied of full 3-D engine structures with regard to the design and operation of the engine under static load conditions. However, several problems arose which required the use of the three dimensional models under dynamic loads to more fully understand what was happening. Full 3-D engine structural models have been used on a regular basis to help understand dynamics related problems. One such problem, addressed herein, is engine related aircraft vibration. Engine related aircraft vibration is noise within the fuselage of the aircraft which can be both felt and heard. To effectively predict engine related aircraft vibration, the entire engine/airframe must be treated as a system.
