摘　　要：为了研究横向喷流技术是否可以抑制鸭式布局弹箭滚转反效问题,开展了基于CFD技术的鸭式布局弹箭气动特性仿真计算。以某鸭式布局弹箭为研究对象,在有无喷流、不同长径比、马赫数、攻角下分析了该弹箭的气动特性差异。计算结果表明:攻角为0°附近,鸭式布局弹箭出现了滚转反效现象;随着攻角越大,鸭舵拖出的下洗流造成的反向滚转力矩也就越小,有利于实现弹箭滚转控制;横向喷流可以显著抑制弹箭滚转反效现象,提高弹箭的滚转控制能力;随着长径比的增加,鸭式布局弹箭的滚转控制能力也在逐渐增强。In order to study whether the lateral jet technology can suppress the roll damping reverse effect of canard layout configuration missile,this paper conducts CFD-based aerodynamic characteristic simulation of canard layout configuration missile.Taking a certain canard layout configuration missile as the research object,the aerodynamic characteristics differences between the missile with and without jet,different aspect ratios,Mach numbers,and attack angles are analyzed.The simulation results show that:at attack angle of 0°and Ma=1.7,the canard layout configuration missile exhibits roll damping reverse effect;As the attack angle increases,the roll damping reverse moment caused by the wash flow from the duck rudder becomes smaller,which is beneficial for roll control of the missile;The lateral jet can significantly suppress the roll damping reverse effect of the missile and improve its roll control ability;As the aspect ratio increases,the roll control ability of the canard layout configuration missile is gradually enhanced.
