Aerodynamic Design and Analysis of Canard Rudder for Gliding Extended Range Projectile

In order to assure that the range of gliding extended range projectile can be extended efficiently,the aerodynamic design and analysis of canard rudder surface of gliding projectile were carried.The principle used to confirm rudder surface parameters of guided projectile was explained.In point of the gliding extended range projectile,the choice of canards parameters and the confirmation method of canards size were studied.The simulation results show that the aerodynamic performance of rudder surface confirmed by this method can provide enough stability while projectile is flying in the course of gliding control.The static stability storage is about 4%.The flexibility is better,and 6° balanceable angle of attack can be brought about when rudder surface is rotated 10°.The matching between stability and flexibility,rotating angle of canard and balanceable angle of attack is better.The method provides reference for the aerodynamic design of rudder surface simulation of the gliding extended range projectile.
