舵片修正弹丸气动特性仿真研究

为了研究舵片修正弹丸的气动特性，建立了不同舵高和舵偏修正弹丸的三维模型，利用有限元分析和动力学仿真软件对弹丸模型进行分析和仿真，得出舵片不同高度、不同舵偏的弹丸在不同攻角、不同马赫数下的气动特性和不同舵片高度和不同舵偏角弹丸的气动特性变化规律，弹丸的气动力特性随舵片高度和舵偏角的变化而变化，其中50 mm高的舵片较其他舵片对弹丸阻力以及升力的影响较大，而8°舵偏角较其他舵偏角对偏航特性的影响较大。

Simulation Study of Pneumatic Character About the Steering-Corrected Projectile

For studying the pneumatic character of the steering-corrected projectile,3D model of different height and rudder angle of steering was established.The model of projectile was analyzed and simulated by using finite element analysis software and dynamics simulation software and resulted the pneumatic character about the projectile of different height and different rudder angle under different deflected angle and different velocity,and variational law of pneumatic character.The resistance is obtained and that the lift force is mainly influenced by the 50 mm height of steering,and the character of deviation is mainly influenced by the 8 degree deflected angle.
