The flutter analysis model of composite rudder is established, and the flutter velocity at ambient temperature is calculated, the influence of canine spectra kc 3 intranasal single dose 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 575.8 m/s at sea level, and flutter coupling form of the composite rudder is a typical bending and torsional modal coupling.The flutter velocity of composite rudder increases with the flight height, and it is related to the frequency difference between the first-order modal and the second-order modal.When the frequency difference between the first-order modal and the second-order modal increases, the flutter velocity of the composite rudder increases correspondingly.

The frequency difference between the first-order click here modal and the second-order modal is increased by adjusting the layup angle, layup proportion and layup sequence, thereby the flutter velocity of the composite rudder can be increased.
