摘　　要：介绍了子母弹气动干扰风洞实验新方案的特点及实验装置的构成。利用该方案进行了布撒器—子弹气动干扰风洞实验。实验结果表明阻力系数干扰量、升力系数干扰量随子弹的轴向位置振荡变化;随子弹的下移气动干扰量减小;子弹的攻角对气动干扰影响不大;在布撒器尾翼区子弹的气动干扰量变化很大;布撒器尾迹对子弹的阻力有很大影响。对亚音速子母弹气动干扰区边界的界定标准应仔细进行研究。The feature of the aerodynamic interference wind tion of the experiment devices are introduced in this paper tunnel experiment for submunition and the composiUsing this scheme, the dispenser-submunition aerodynamics interference experiment was carried out. The experiment results show that the interference of the drag coefficient and the lift coefficient vary violently as the axial position changes, and decrease as the submunition movement away from the dispenser in vertical direction. The angle of attack of the submunition doesn＇t play a role in the aerodynamic interference. The aerodynamic interference is very strong in the zone of the dispenser＇s empennage. The dispenser＇s wake affects the drag of the submunition acutely. It should be studied in detail that how to define the boundary of the aerodynamic interference zone for the dispenser and submunition in the subsonic flow.
