Example Embodiment

[0044] The invention also discloses a preparation method of hydrocarbon fuel-rich propellant, which comprises the following steps:

[0045] (1) Weighing: Precisely weigh each component in a dry environment for use;

[0046] (2) Mixing: Add functional additives to the adhesive and mix by hand to obtain a pre-mixed slurry, then add the metal fuel, hydrocarbon fuel, and oxidizer to the vertical mixer to mix uniformly, and then add the curing agent to continue Mix, control the mixing temperature to 30℃~50℃, the mixing time is 70min~110min, wait until the system is completely mixed and uniformly discharged;

[0047] (3) Pouring and curing: the slurry is vacuum poured and cured in a dry environment at 50°C to 70°C for 5 to 8 days to obtain a propellant product.

[0048] According to the characteristics of hydrocarbon fuel solid propellant, adjusting the relative performance of hydrocarbon fuel-rich propellant can make it widely used in a variety of advanced air-breathing power plants, such ...

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...
