Design of modern rotorcraft engines requires that aeroelastic considerations be included for prediction of instabilities due to engines-rotors-airframe interference. Computational approaches are presented which have generality in the selection of stress analysis methods are applicable to rotorcrafts involving a large number of operation variables. An instability criterion for the prediction of fatigue effects of alternating stresses on engine structural integrity is identified and applied to the corresponding airframe behavior during high speed forward flight and severe rotorcraft maneuvers.
