摘　　要：探讨了非圆截面弹身布局先进高超声速武器(AHW)的气动特性。以类AHW双锥十字小尺寸弹翼布局为研究对象,基于贝塞尔曲线方法建立飞行器外形,利用多目标遗传算法优化分析飞行器弹体布局,在此基础上对飞行器圆截面弹身布局和非圆截面弹身布局进行升阻比及压心分析;考虑总体和防热的需求,对不同截面飞行器控制舵的类型、尺寸匹配和弹体质心位置选择以及操纵面的效率进行对比分析。研究表明,类AHW非圆截面弹身布局可以实现较高的配平升阻比,合理的质心位置和舵面尺寸组合能够实现比圆截面布局更好的操纵需求。The aerodynamic characteristics of advanced hypersonic weapon(AHW)with non-circular section body design was explored.The aerodynamics configuration optimization about biconic body with cruciform small size flaps for AHW analog boost gliding vehicle was studied,and the aircraft shape was established based on bezier curve method.A multi-objective genetic algorithm was used to optimize and analyze the design of aircraft projectile.On this basis,lift-drag ratio and pressure center of the circular section and non-circular section of aircraft projectile were analyzed.Considering the overall and thermal protection requirements,the types,size matching,the location selection of the center of mass of the projectile and the efficiency of the control surface of aircraft with different cross sections were compared and analyzed.The research shows that AHW analog boost gliding vehicle designed with non-circular cross-section missile can achieve higher trim lift-drag ratio,and reasonable combination of centroid position and rudder size can achieve better control requirements than circular cross-section design.
