摘　　要：利用计算流体力学(CFD)方法对偏转弹头控制导弹和鸭舵控制导弹在不同马赫数、攻角和控制面偏角等状态下的流场进行数值模拟,并对两者的阻力特性、升力特性和俯仰力矩特性等气动特性进行了比较分析。得出偏转弹头控制具有气动性能好、控制效率高、机动性强等特点,其控制效率随着马赫数的增加而增加,是导弹高速飞行过程中快速响应控制的理想方式。A computational investigation has been completed at Mach number of 2,3,and 4 to compare the aerodynamic characteristics and pitch control effectiveness of missile with deflectable nose and canard controls. The computation results indicate that compared with canard control,deflectable nose control has strong points in aerodynamics,control effectiveness and maneuverability,the control efficiency increases as the Mach number increases. Thus deflectable nose control is a perfect control method of hypersonic missile.
