| 摘 要： | 针对烧蚀可能对返回舱带来的不利影响，开展了类联盟号返回舱烧蚀外形的气动特性数值计算与分析。结果表明：因烧蚀引起的气动外形改变后，会使配平攻角绝对值增大，配平升阻比也相应增大。该结论可为类联盟号返回舱外形的气动布局设计和改进提供参考。

| Abstract: | Numerical simulation and analysis of aerodynamic characteristics of like Soyuz return capsule ablation shape is carried out in this paper for the adverse influence come from ablation. The result indicates that the shape change caused by the ablation will increase absolute values of both trim angle of attack and trim lift-drag ratio. The conclusion offers a reference for the aerodynamic layout design and improvement of the Soyuz return capsule. |
