Title The Design of 220mm60km-Rocket Projectile
Abstract
During World warⅡ, rocket weapons played a great power and sped up the process of the war, which left indelible impression. therefore, all the countries of the world started to develop and improve rocket weapons. However, due to the limitation of the theory and technology, the rocket weapon is of short range,
Small power, low hit rate and it is not convenient to use. With the development of science and technology, many technical problems of rocket weapons have been solved, which makes the performance indexes of rocket weapons could be greatly improved. Now, long-range, accurate, powerful, multipurpose rocket weapons has become the main development trend. In order to improve the range and increase power, we must increase the quantity of explosive in warhead and the charge of propellant in rocket engine, so do the projectile caliber. This article which is aimed at the development trend , designs a rocket projectile with large caliber to achieve the main target of improving the range.

本章主要讲述了火箭武器的性能特点及运用，分析了国内外火箭武器的现况及其发展趋势，并简要介绍研究内容及要求。
1.1 火箭武器性能特点及运用
现代战争中，胜败的决定因素已经不再是人数，而是技术。科技的发展改变了战争形式，未来战场将被高科技武器主导。与坦克炮并列作为战场佼佼者的火箭武器越来越受到人们的重视，因而得到飞速的发展，并且在近年来的局部战争中得到广泛应用。目前，火箭武器已成为常规炮兵及其他兵种武器装备的重要组成部分，与身管火炮相比，具有其独特的优势。
