摘要
在研究航天飞机再入返回问题时,确定再入飞行走廊和再入飞行轨迹是基础的研究问题之一。对于这方面的工作,参考文献[1]作了较详细的介绍。国内的一些作者在航天飞机方案论证时开始注意考虑这类重要的问题[2、3、4]。然而,他们所讨论的基本模型没有考虑地球自转对再入运动的影响。这种近似模型,对深入一步的方案论证就显得不能满足了。本文建立了一个精确的模型,给出与方案论证有关的仿真结果。
In researching space shuttle reentry, determination of entry flight corridor and entry trajectory is one of the fundamental subjects. Some detailed recommendation about this work was published abroad(l), and some authors in our country (2, 3, 4) begin to notice this important subject during demonstrating conceptive scheme of space shuttle. However, an effect of the earth selfrotation to reentry motion was not considered in the fundamental model. Such approximate model does not satisfy the requirement for further development. In this paper, a precise model has been established and a simulated result concerning scheme of space shuttle has been given.
