摘要迫击炮是一种伴随步兵的常用武器,用来完成摧毁敌方工事和消灭敌方有生力量的作战任务。它在过去的战争中发挥了重大作用,在未来的战争中仍是一种十分重要的武器。虽然迫击炮有很多优点,但由于其散布较大,因而也限制了迫击炮的使用和发展。幸好由于弹道修正弹的发展,特别是横向脉冲发动机控制的提出、应用和发展,为迫击炮弹的精确化带来了曙光。60658
作者是在了解国内外脉冲发动机的发展和成果的基础上,提出了一种基于迫击炮弹的脉冲控制机制,并描述了其组成及工作原理。首先利用PROE软件进行了三维模型,然后应用ANSYS软件进行了强度分析,并使用MATLAB软件进行了弹道仿真。

Title The Design and Research of Lateral Pulse Jet Based on the 82mm Mortar
Abstract
Mortar is a kind of guns commonly used along with the infantry, whose task is to destroy the effectives and fortifications of the enemy. In the past it played a large role in the war and in the future it is still a very important weapon in the war. The mortar has many advantages, but its dispersion limits the use and development of mortar. Fortunately, the development of the trajectory correction projectile, especially the lateral pulse jets control mechanism, has given a hope for accurate of mortars.
In this paper, after studying the development and achievements of the lateral pulse jet, the author has proposed a kind of pulse control mechanism based on a kind of mortar and has described its composition and how it works. I have constructed a 3-D model using PRO/E, conducted the strength analysis using ANSYS, and emulated the external ballistic of the trajectory correction using MATLAB.
