CZ-2E火箭高空风弹道修正

CZ-2E Ballistic Correction for High Altitude Wind

高空风引起的气流攻角对火箭飞行中的气动载荷和飞行环境有较大的影响。这种影响有时可造成火箭飞行失败。为尽可能地改善火箭的飞行条件 ,在弹道考虑上 ,可采用降低飞行中气流攻角的弹道设计方案——以高空风弹道修正法来降低飞行中的气流攻角。

There is a larger effect of flow angle of attack caused by high altitude wind on aerodynamic load and flight environment in rocket flighting. This effect can make flighting rocket flight fail sometimes. For improving rocket flight conditions as well as possible, in ballistic design, the ballistic design concept of decreasing flow angle of attack in rocket flighting, i.e.,to decreasing flow angle of attack in rocket flighting with ballistic correction method of high altitude wind can be used. The principle, method and correspending computation model of ballistic correction of high altitude wind are mainly introduced in this paper.
