A structural dynamics study of a wing-pylon-tiltrotor system
A simple structural model for a three-bladed tiltrotor-pylon-wing assembly is presented, which accounts for chor-dwise, transverse, and torsional wing deformations, rigid pylon pitching motion with respect to the wing tip cross-section in its deformed position, lead-lag, flap, and torsional deformations of rotor blades. The model considers equivalent viscous damping associated with blade and wing elastic deformations and with rigid
