摘　　要：提出一种鸭式滑翔增程导弹的气动外形,并通过数值仿真方法分析了其升阻特性和滚转控制特性,研究了鸭舵洗流对全弹滚转控制特性的影响机理。仿真结果表明,该滑翔增程外形导弹升阻比增大;鸭舵进行滚转控制产生的洗流作用使得主翼和尾翼均产生与鸭舵控制力矩反向的滚转力矩;主翼可减弱鸭舵对尾翼的下洗作用,但在下洗流对主翼和尾翼的综合作用下,全弹滚转控制效率较无主翼时更低。因此,在设计中需综合考虑导弹升阻特性和滚转控制能力。A gliding extended range canards-controlled configuration was proposed,its lift-drag characteristic and rolling characteristic were analyzed by using numerical method,and the influence mechanism of canard-rudder downwash on rolling control characteristic of the missile was investigated.The simulation results show that the lift-drag ratio of gliding extended range configuration has been increased. The reverse rolling moment on main wing and tail were generated due to canard-rudder downwash under rolling control. The influence of canard-rudder downwash on tail could be weakened by the main wing. However,under the combined influence of the canard-rudder downwash on main wing and tail,the rolling control efficiency of the missile was lower than that without main wing.Therefore,it is necessary to comprehensively consider the lift-drag characteristic and rolling control efficiency in the gliding extended range canard-controlled configuration design.
