Heat resistant structure of flying body and manufacturing method of heat resistant structure of flying body

A heat resistant structure, applied to a flying body comprising:

• a tip part arranged at a front end of the flying body with respect to a direction of travel of the flying body;
• and
• a body part arranged in a back direction from the tip part with respect to the direction of travel of the flying body,
• wherein the tip part comprises:
• a surface member arranged on an outer surface of the tip part, the surface member having a melting point higher than a maximal temperature reached on a surface of the flying body when the flying body moves in an atmosphere and is heated;
• a base part configured to couple the surface member to the body part;
• and
• an insulation member arranged between the surface member and the base part, the insulation member configured to thermally insulate the base part from the surface member,
• wherein the surface member comprises a surface member protrusion that protrudes from an inner surface of the surface member to an inner space of the surface member,
• wherein the tip part further comprises:
• an abutting member of which at least a part is arranged in a front direction from the surface member protrusion with respect to the direction of travel of the flying body, the abutting member being configured to abut on a front surface of the surface member protrusion;
• and
• a coupling member configured to couple the abutting member and the base part, and
• wherein the base part comprises a base part abutting surface configured to receive a reaction force from the surface member from the front direction.
