There is a larger effect of flow Angle of attack caused by highaltitudewind on aerodynamic load and flight environment in rocket flighting.
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。

Wind velocity also increases with altitude and may cause serious stress for trees, as is made evident by the deformed shapes at high altitudes.
风速也随着海拔高度的增加而增加,可能给树木带来严重的压力,这从高海拔地区的变形就可以看出来。

The aim of both teams is to tap into high-altitudewind, which is an energy source that is more abundant and reliable than the ground-level wind on which normal turbines depend.
