New Approach to Preventing External Overheating of High-Speed Aircraft
摘要
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.
