Abstract

The invention discloses a hydrocarbon fuel for a solid fuel ramjet engine and a preparation method thereof. The hydrocarbon fuel comprises the following components by mass: 47.5%-85% of high-density polyethylene, 10%-47.5% of paraffin and 2%-5% of a carbon functional additive. The method comprises the following steps of: uniformly mixing the raw materials in proportion, performing screening, putting a powder sample into a mold, performing heating to melt, applying pressure to the mold filled with the molten sample, conducting standing, cooling, solidifying, and demolding to obtain the hydrocarbon fuel. The solid fuel disclosed by the invention is good in compactness, almost free of shrinkage cavities and cracks, simple and convenient in preparation method, cost-saving and time-saving, andconvenient to apply.

Description

technical field [0001] The invention relates to a hydrocarbon fuel for a solid fuel ramjet engine and a preparation method thereof, belonging to the technical field of hydrocarbon fuel preparation. Background technique [0002] Solid fuel ramjet uses solid fuel as a power source, and its excellent performance is based on the combustion characteristics of solid fuel. The better the combustion performance of solid fuel, the greater the potential advantage of solid fuel ramjet. [0003] In order to make up for the shortcomings of solid fuel propellants in certain application fields, expand the application range of solid impulse engines, and improve the combustion performance of solid fuels, it is necessary to optimize the formulation of solid fuel components. At present, the preparation method of solid hydrocarbon fuel with excellent ignition performance, high combustion efficiency, less condensed phase, relatively clean gas and less residue is cumbersome, and the production cy...
