摘　　要：对旋转稳定弹弹道修正引信的减旋技术进行了探索性研究,提出并建立了七自由度外弹道模型,通过计算和分析表明:采用减旋翼减旋,通过轴承连接引信和弹丸的减旋装置不仅可以使弹道修正引信减旋,而且可以使弹道修正引信在弹道飞行过程中逐步达到较低的平衡转速,为二维弹道修正引信正常工作创造了良好的条件,并且验证了带减旋装置的弹道修正弹满足飞行稳定性要求。The despining device of the course correction fuze for spin-stabilized projectile is studied. 7 free-degree model of the external ballistics of course correction projectile is built. By calculating and analyzing,it is feasible not only to realize the despining of the course correction fuze by using the vaneto despin and connecting the fuze with the despining device of the projectile by bearing, but also to make the fuze keep the low balanced rotating speed in the free flying of the projectile. It provides the good working condition for the two-dimension course correction fuze. And the projectile with the despining device meets the requirements of flying stability. The study results of this paper provide some references for research of the course correction fuze of spin-stabilized projectile.
