摘　　要：针对末敏弹在采用降落伞和其他气动力机构(采用单翼或双翼)稳态扫描时的缺点,提出了一种降落伞和尾翼相结合的布局形式。该布局形式通过在子弹尾部安装三片尾翼,增大子弹下落过程的阻力,减小降落伞的尺寸,提高了末敏弹的整体作战效果。通过对数值风洞模拟和弹道分析的仿真结果表明,这种布局结构可以实现稳态扫描,并可用于末敏弹总体及其稳态扫描装置设计的研究中。A kind of new terminal-sensitive projectile construction is proposed, which combines the parachute and empennage to overcome the defect of terminal-sensitive projectiles in stable scanning when using parachute and other pneumatic structure （single-wing or dual-wings）. This construction builds three empennages at the tail of the projectile,which increases the resistance during projectile descending and reduces the size of parachute. This construction improves the whole combat effect of the terminal-sensitive projectiles. Wind tunnel numerical simulation and trajectory analysis simulation indicate that the proposed tri-wing construction could lead to stable scanning. It could be used in the research on the terminal-sensitive projectiles and the design of their stable scanning equipments.
