1.If it does this could be a problem, since we rely on the stability of the aerogel tiles to be able to reconstruct trajectories, and thus distinguish betwen interstellar dust and interplanetary dust.
如果出现这种情况那将是个问题，因为我们依靠凝胶块的稳固性来重建弹道，并由此区分星际尘埃和太阳系内尘埃。收藏指正
2.In this paper,a finite element model of reusable ceramic TPS tiles is built,and heat transfer within a tile is computed on condition that the tile be perfect,surface-cracked or impacted,with aerodynamic heating,radiation,and heat conduction through the tile and vehicle skin considered,on the basis of which the influence of both damages on temperature distribution is analyzed.
本文针对典型的可重复使用陶瓷防热瓦,建立其有限元传热学分析模型,在考虑气动加热、辐射散热以及防热瓦与飞行器蒙皮之间的传热三种因素的基础上,分别模拟了单片防热瓦在正常情况和发生表面涂层损伤或冲击损伤情况下的传热情况,并进一步分析了两种损伤对于防热瓦温度分布的影响。收藏指正
