Flutter Analysis on Composite Rudder of Air-to-Air Missile

The flutter analysis model of composite rudder is established, and the flutter velocity at ambient temperature is calculated, the influence of the layup scheme on the flutter characteristics of the composite rudder is studied. The results show that the flutter velocity of the composite rudder is 575...
