発明の名称 (英語) SOLID FUEL AND HYBRID ROCKET 新技術説明会
発明の概要(英語) A readily combustible portion (110) has a readily combustible exposed surface (111) exposed in a flow channel (CA). A combustion-resistant portion (140), which comprises a material that does not burn as readily as the readily combustible portion (110), covers an outer surface of the readily combustible portion (110) on the opposite side from the readily combustible exposed surface (111) in a direction orthogonal to a length direction, which is parallel to the direction of advance of a hybrid rocket. The combustion-resistant portion (140) has a thick portion (120) serving as a stopper portion for preventing separation of the readily combustible portion (110) from the combustion-resistant portion (140) in the direction from a starting end surface (100a) toward a terminal end surface (100b).
従来技術、競合技術の概要(英語) BACKGROUND ART
Solid fuel (hereinafter, referred to as the solid fuel) of a liquid oxidizing agent (hereinafter, referred to as a liquid oxidizer) is supplied to the combustion of solid fuel, the combustion gas generated in the combustion can be ejected to obtain a thrust in a hybrid rocket has been known. "Hybrid" is to be noted that, in order to obtain the thrust of the solid and liquid material can be used to mean both.
Solid fuel, hybrid rocket propulsion and extends in a direction that defines a flow path. In the flow path, the oxidizing agent liquid is injected. Thus, the combustion gas flow path in the flow occurs, the solid fuel is combusted.
Patent Document 1 is, such as a solid fuel, a relatively easy material tends to combust the combustion section, it is difficult to combust a relatively hard material and the combustion section, a hybrid rocket propulsion direction, are alternately arranged and configured with the disclosure.
