Abstract

External overheating of high-speed aircraft may be prevented by means of composites with significant longitudinal anisotropy. (The longitudinal thermal conductivity is two orders of magnitude greater than the transverse thermal conductivity.) In this approach, the heat fluxes that result from aerodynamic heating are channeled within the anisotropic composites from the hottest region (the front critical point) to the tail of the truncated cone. As a result, the vicinity of the front critical point is cooled and the tail of the cone is heated, with considerable decrease in the associated heat fluxes.

防止高速飞机外部过热的新方法

摘要利用具有显著纵向各向异性的复合材料可以防止高速飞机的外部过热。(纵向热导率比横向热导率大两个数量级）。在这种方法中，气动加热产生的热通量会在各向异性复合材料内从最热区域（前临界点）流向截顶锥的尾部。因此，前临界点附近被冷却，锥体尾部被加热，相关的热通量大大减少。
