Abstract
A comprehensive aeroelastic analysis that can predict the performance, vibratory loads and aeroelastic stability of composite-coupled advanc ed geometry tiltrotors that include gimballed hub, elastic wing and el astic fuselage motion is presented, Helicopter, conversion and airplan e modes of operation are modeled. Predictions from this analysis for t rim controls, response, loads and aeroelastic stability correlate as w ell with test data as do predictions from other established analyses.
