Flutter Characteristics Analysis of Variable Swept Wing Missile with Large Aspect Ratio
In order to increase the internal space of the missile and reduce the air resistance,the missile shape in-creasingly tends to a large aspect ratio mechanism,and such a design is easy to cause obvious aeroelastic problems such as low-frequency flutter of the missile.This problem can be solved by adjusting the aerodynamic shape of the missile and changing the aerodynamic characteristics of the system to suppress flutter.In this paper,the variable swept wing,one of the variant aircraft technologies,is studied.Around the flutter problem of missiles with large aspect ratio,the influence law of flight speed on the flutter characteristics of missiles in flight is revealed,and then the feasibility of actively suppressing the flutter of missiles by changing the sweep angle of missiles is verified,which provides theoreti-cal support for solving the flutter problem of missiles.
