为提高一维弹道修正弹修正能力,提出并设计一种新型的一维弹道修正机构。以旋转稳定弹为研究平台,在美式M2A1型105mm口径榴弹上加装阻力修正机构,利用Adams和Fluent仿真软件对修正机构工作过程进行数值仿真,初步验证了该机构设计的可行性。研究结果表明:机构展开前后阻力系数比为2.2左右,动作一致性好,展开过程迅速且稳定可靠,满足对一维弹道修正能力的要求。可为一维弹道修正机构的进一步设计和实际应用提供帮助。

In order to improve correction capability of one-dimensional trajectory correction projectile, a new one-dimensional trajectory correction device was proposed and designed. Taking spin-stabilized projectile as research platform, the 105 mm caliber grenade was fixed with resistance correction mechanism, Admas and Fluent were used to work out working process of the mechanism, feasibility of the mechanism design was verified. The results show that the resistance coefficient ratio can reach about 2. 2 between before and after the mechanism works. It performs well in synchronization, reliably and speed, satisfying one-dimensional trajectory correction ability. The result is helpful for further design and practical application of one-dimensional trajectory correction mechanism.
