| 摘 要： | 对材料烧蚀性能研究方法进行了分析，认为理论计算与地面模拟试验相结合是评价材料烧蚀性能的有效手段。在地面模拟试验中，针对设备的局限性，采用提高气动压力的方法来补偿由于热流密度不够造成的加热量不足，并将其结果与理论计算修正值进行比较，得到了很好的一致性结果。还对影响再入加热量的两个重要参数气动压力和热流密度对材料烧蚀量的影响进行了分析，认为气动压力比热流密度对材料的烧蚀性能影响更大。

| Abstract: | The method of studying ablation properties of material is discussed in this paper, and it is indicated that the combination of theoretic computation and ground simulation test is an effective method to estimate the ablation properties of material. In the ground simulation test, and air driven pressure is increased to compensate for lack of heat because of lack of heat flux density, and a comparison between the result and correctional value of theoretic computation results in good consistency. The effect of air driven pressure and heat flux density on the ablation of material is analyzed in the paper, and the author believes that the former influences the ablation of material more than the latter. |
