Abstract: A paraffinic fuel manufacturing apparatus for hybrid rockets is provided to enable paraffinic fuel to be solidified when paraffin wax fused by high-pressure gas is pressurized and cooled in a gravity direction under a state of minimizing the contraction of paraffinic fuel in a radial direction. A method for manufacturing paraffinic fuel for hybrid rockets comprises the following steps of: fusing paraffin wax in a fuser; placing the fused paraffin wax in a casting frame; injecting high-pressure gas to the casting frame in order to pressurize the fused paraffin wax to be solidified; and taking the solidified paraffin wax out of the casting frame. The solidifying step minimizes the contraction in a radial direction.

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).
