Title Research on stabilization technology of the attitude of reconnaissance projectile in the air
Abstract
Reconnaissance projectile is a new type of reconnaissance equipment which implements reconnaissance by a variety of ways, such as parachute reconnaissance, landing reconnaissance and gliding reconnaissance. It’s been applied in many countries. In this paper, the projectile’s trajectory in the air is analyzed, a technical program, that is the way of adopting a device to slow down the submunition’s velocity of deceleration and despining is also provided. The dynamic characteristics of parachute-submunition system in the process of deceleration and despining are analyzed, the motion equations of the submunition are established subsequently. On the condition of some parameter is assumed in advance, rotary parachute, deceleration parachute and rotating damping wings are designed. The parameter of movement in the phases of deceleration and despining is analyzed by using the Matlab software. The effects of parachute in different primary conditions are also analyzed. Finally the effectiveness of the way above-mentioned in some assumed parameter is analyzed.

1.1 侦察弹的研究背景和意义
对于战争的谋略，我们的先人早已指出：“知己知彼，百战不殆；不知彼而知己，一胜一负；不知彼，不知己，每战必殆。”（语出《孙子•谋攻篇》）。这句话的大致意思是说：在军事纷争中，既了解敌人，又了解自己，百战都不会失败；不了解敌人而只了解自己，胜败的可能性各半；既不了解敌人，又不了解自己，那只有每战必败的份儿了。用现代的语言就是掌握交战双方的信息至关重要。古代的战争中，一是直接从战场获得敌我双方的数量、装备、士气等一系列的影响因素，二是间接地体现在通过派遣间谍，暗地里获得敌方的相关信息。
