再入航天飞机表面热流密度辨识

本文给出了求解表面热流密度辨识这一热传导逆问题的顺序函数法。然后以某模型航天飞机迎风中心线上的某特征点为例，将航天飞机再入时的表面热流密度辨识问题简化为一维模型问题，用顺序函数法来对该特征点上的对流加热流密度进行了仿真辨识，得到了较理想的辨识结果。该方法在航天研究领域有着良好的工程应用前景。

SURFACE HEAT FLUX IDENTIFICATION OF REENTRY SPACE SHUTTLE

In this paper,the Sequential Function Method(SFM) which is used to solve the inverse heat conduction problem of surface heat flux identification was introduced at first.And then,by taking a characteristic point on the windward center line of a model space shuttle as an example and simplifying this surface heat flux identification problem to one dimensional case,the SFM was used to identify the history of the surface heat flux on the characteristic point successfully.The result shows that this identification method has a bright prospect of engineering practice in the astronautical research field.
