| Abstract: | Tiltrotor/pylon/wing aeroelastic instabilities limit the forward flight velocity and flight efficiency.As too many parameters influence tiltrotor aircraft aeroelastic instabilities,analytical models become more and more complicated and the physical understanding is one of the most difficult problems.Based on analytical models, tiltrotor/pylon whirl flutter and tiltrotor/pylon/wing aeroelastic stability analyses are reviewed in the paper.In addition, parametric studies,wind tunnel tests and flight tests are reviewed as well.The author hopes to give an introduction for tiltrotor/pylon/wing aeroelastic stability investigations. |

| Keywords: | tiltrotor aircraft aeroelastic dynamics whirl flutter dynamic stability |
