HEAT-RESISTANT STRUCTURE OF FLIGHT BODY AND METHOD FOR MANUFACTURING THE HEAT-RESISTANT STRUCTURE OF FLIGHT BODY

To provide a heat-resistant structure of a flight body having a tip that can endure aerodynamic heating generated when moving at high speed in the atmosphere, and a method for manufacturing the heat-resistant structure of the flight body.SOLUTION: A heat-resistant structure of a flight body (1) comprises a tip (20, 30, 40, 50), and a body part (10). The tip is disposed at a tip of a front part relative to a direction (X) of travel of the flight body. The body part is disposed behind the tip relative to the direction of travel. The tip comprises a surface member (21, 31, 41, 51), a base (23, 33, 43, 53), and a heat insulation member (22, 32, 42, 52). The surface member is arranged on an exterior surface (241) of the tip, and has a melting point that is higher than a desired temperature. The surface member is joined to the body part by the base. The heat insulation member is arranged between the surface member and the base in order to insulate the base from the surface member.SELECTED DRAWING: Figure 3A 【課題】大気中を高速で移動するときに発生する空力加熱に耐え得る先端部を有する飛行体の耐熱構造と、この飛行体の耐熱構造の製造方法とを提供する。【解決手段】飛行体（１）の耐熱構造は、先端部（２０、３０、４０、５０）と、胴体部（１０）とを備える。先端部は、飛行体の進行方向（Ｘ）に対して前方の先端に配置されている。胴体部は、進行方向に対して先端部の後方に配置されている。先端部は、表面部材（２１、３１、４１、５１）と、基部（２３、３３、４３、５３）と、断熱部材（２２、３２、４２、５２）とを備える。表面部材は、先端部の外側表面（２４１）に配置され、所望の温度より高い融点を有する。基部は、表面部材を胴体部に結合する。断熱部材は、表面部材と基部との間に配置されて基部を表面部材から断熱する。【選択図】図３Ａ
