Abstract: 이로써, 그레인포트의단면적이출구측으로갈수록증대되거나감소하도록형성되어산화제가고속으로유입됨에따른열전달을증가시켜후퇴율을증가시키고불균일도를개선하는효과를갖는다.

Abstract: PURPOSE: A solid fuel of a hybrid rocket including an inclined grain port is provided to solve unevenness of part fallback and improve average fallback by increment of heat transfer rate according to the high speed inflow of oxidizer. CONSTITUTION: A solid fuel of a hybrid rocket including an inclined grain port comprises a grain port(11). The sectional area of a grain port is changed along a longitudinal direction. The sectional area of the grain port is gradually increased from an inlet(10a) to an outlet(10b). The change of the sectional area of the grain port is formed into a fixed rate according to the unit length of a solid fuel(10).
