回收过程中高空风场的特点及描述

The Characteristics and Description of Mid-High Altitude Wind in Recovery

风场对航天器的发射、飞行及落点的影响不可忽略。文章针对回收过程的中高空风场主要因素的基本概念及特点进行了简单综述 ,并阐述了如何用综合风剖面法对回收过程中高空风场进行描述 。

The effect of wind can not be ignored, especially on analysis of launch and flight and landing point of spacecraft. The basic concepts and characteristics of the major factors, which is of mid-high altitude wind field in recovery, are briefly generalized in this article. And the basic method, Synthetic Wind Speed Profile, is used to describe the mid-high altitude wind field in recovery. Finally, some statistic characters are found based on measured data of north part of China.
