静不稳定尾翼式火箭的随机风偏与零风偏原理

THE FORMULA OF THE RANDOM WIND DISPERSION OF THE UNGUIDED UNSTABLE FINNED ROCKET AND THE PRINCIPLE OF ZERO WIND DISPERSION

本文推导了静不稳定非制导尾翼式火箭的随机风偏公式,并给出用数字计算机计算的便于工程使用的特征函数表。从风偏形成的基本概念出发,本文还提出了人为地使折叠尾翼在火箭飞离发射器后一段时间再张开,从而使风偏为零的原理。

In this paper, the formula of the random wind dispersion of the unguided unstable finned rocket was derived. Then using digital computer, the table of characteristic function for engineering calculation was given. In total dispersion, the random wind dispersion of the unguided finned rocket is very important. Therefore, in this paper, the principle of the zero wind dispersion was suggested, i. e. in a confined period after the launch of the rocket, the folded fins of the rocket spread out.
