摘要 应用二维流场理论开辟高速滑膛尾翼弹后效开翼的新途径.在分析现有国内外弹丸尾翼稳定装置的结构特点及优缺点的基础上,提出了稳定装置的改进方向,并设计出了一种新型稳定装置结构,对新型稳定装置进行了结构分析、强度计算、气动力分析及膛内自锁可靠性的计算,并用二维流场理论分析了弹丸尾翼的张开过程.证明了尾翼弹后效开翼途径的可行性. The features of various kinds of super caliber stabilized assembly of fin stabilized projectile are reviewed and analyzed in this thesis. A new idea that to abandon the traditional cylinder and to take the aerodynamic force of the muzzle blast as the only fin extending force is put forward based on the above analysis and is implemented in a projectile. In conclusion, both the theoretical analysis and the result of the caculation have shown that the idea of unfolding the fins in the intermediate period is practicable.
