A kind of hydrocarbon rich fuel propellant and preparation method thereof

Abstract

The invention discloses a hydrocarbon fuel-rich propellant. The hydrocarbon fuel-rich propellant comprises components in percentage by mass as follows: 20%-45% of hydrocarbon fuel, 27%-41% of an oxidizing agent, 3%-20% of metal fuel, 15%-25% of an adhesive system and 2%-7% of a functional additive, wherein the hydrocarbon fuel is a polycyclic aromatic hydrocarbon compound, and the adhesive systemcomprises an adhesive and a curing agent. The invention further discloses a preparation method of the hydrocarbon fuel-rich propellant. The polycyclic aromatic hydrocarbon compound which has weak polarity and is not sublimated at the normal temperature is taken as hydrocarbon fuel to be introduced into the fuel-rich propellant, propellant structure damage caused by hydrocarbon fuel sublimation ina storage process of the propellant is eliminated completely, storage performance of the propellant is greatly improved, combustion performance of the propellant is improved, energy release efficiencyis increased, condensed phase is reduced, and the requirement of a solid propellant ramjet for energy, process and combustion performance of the propellant is met.

Description

technical field [0001] The invention relates to the technical field of fuel-rich propellants, in particular to a hydrocarbon-rich fuel propellant and a preparation method thereof. Background technique [0002] Since the 21st century, all countries in the world have attached great importance to beyond-visual-range non-contact operations. Therefore, the role and status of a new generation of tactical missiles capable of supersonic, high maneuverability, and long-distance target attack missions in a wide airspace have become increasingly prominent. The development of new high-performance aircraft requires the propulsion system to have the characteristics of high speed, large load, long range, small volume, low mass, simple structure, and high flexibility, which puts forward higher requirements for the performance of the propulsion system. [0003] The solid impulse motor organically combines the advantages of solid rocket motors and air-breathing motors. The use of oxygen in t...

Problems solved by technology

[0004] The solid-impulse engine uses fuel-rich propellant as the power source, and the fuel content reaches 30-50%. Therefore, fuel performance is one of the key factors that determine whether the potential excellent performance of the solid-impulse engine can be fully exerted. The boron-containing fuel-rich propellant has great High calorific value is the preferred propellant for solid impulse engines. However, due to some characteristics of boron itself, its application in some special fields is restricted.
