The invention relates to a thermal protection structure of a high-speed aircraft. The thermal protection structure comprises a thermal insulation coating, an alloy layer, a temperature equalization layer and a micro-rib structure layer which are arranged in sequence, wherein the micro-rib structure layer comprises a titanium alloy plate and a plurality of wing-shaped micro-ribs which are arrangedon the upper surface of the titanium alloy plate and have the same chordwise direction; and the wing-shaped micro-ribs are arranged between the temperature equalization layer and the titanium alloy plate. By means of the structure, the weight of the thermal protection structure can be greatly reduced.
本发明涉及一种高速飞行器的热防护结构,所述热防护结构包括:依次设置的隔热涂层、合金层、均温层和微肋结构层;所述微肋结构层包括钛合金板以及设置在所述钛合金板上表面的若干个弦向相同的翼形微肋;所述翼形微肋设置在所述均温层和所述钛合金板之间。通过本发明的上述结构,能够大幅降低热防护结构的重量。
