90mm航空火箭弹总体设计

摘要目前大口径的航空火箭弹已被机载导弹代替，而且空空火箭弹使用的越来越少但由于火箭弹的射程远、威力大，空地型火箭弹已成为武装直升机对地攻击的重要武器。

本文主要是以 90mm-1 型火箭弹为参考，在详细了解其战术指标以及各个部件的尺寸及相互作用后，学习设计弹径 90mm、射程达到 8 千米以上的航空火箭弹。69471

本文行文思路是首先经过计算与比较，提出总体指标。在根据指标在三维软件上画出三维构型，根据三维建模利用书中公式计算出火箭弹的气动参数，满足静稳定性后，再进行外弹道的设计。外弹道的设计目标是在满足射程的前提下，求出发动机推力和工作时间等参数。然后，根据外弹道的指标进行火箭发动机设计，确定装药药型、结构尺寸等参数。最后，对燃烧室壳体等零件进行强度校核。

Title 90mm Aviation rocket design

Abstract

At present, the large caliber a aviation rocket have been replaced by airborne missiles and the use of air to air rockets is fewer and fewer. But air to surface rockets have played an important part in the attack means of gunship

The main purpose of this paper is to analyze 90mm giant rat rockets as a reference. After a detailed understanding of the tactical and technical index and the size of each component and interaction, learning design elastic diameter 90mm, range up to 8km above the air rocket.

This paper is the first of the thinking of the calculation and comparison, the overall indicators. According to the indexes, the 3-D map is drawn from the 3D software, and the aerodynamic parameters of the rocket projectile are calculated by using the formula of the book, and the design of the outer ballistic is met.. The design target of the exterior ballistic is to meet the range of the premise, and the engine thrust and working hours and other parameters. Then, according to the external ballistic indicators of rocket engine design, determine the charge type, structure size and other parameters. Finally, the strength of the combustion chamber shell is checked.
