“…Gel propellant not only inherits the characteristics of high specific impulse, multiple start-ups, and adjustable thrust of liquid propellant but also has the advantages of solid propellants, such as non-leakage, long-term storage, easy use, and maintenance [11]. Gel engine has broad development and application prospects in the field of missile weapons and space thrusters and has become a new propulsion technology widely studied [12][13][14][15].…”

The addition of aluminum particles to gel propellants can improve combustion performance. However, the agglomeration of aluminum during the combustion process can result in a series of negative effects. In this paper, the aluminum agglomeration inhibition method of gel propellant based on carbon synergistic effect is proposed. Carbon particles exhibit excellent combustion properties, and the gaseous product CO2 generated during combustion can mitigate the agglomeration of aluminum. The research demonstrates that incorporating carbon particles into aluminum-containing gel effectively reduces the incomplete combustion of aluminum particles and increases the volumetric calorific value of the gel. When the mass fraction of carbon is 5 wt%, the volume calorific value of the gel reaches the highest. Meanwhile, the rheological experiments show that the addition of carbon particles can improve the shear-thinning properties of the gel, which is beneficial to the atomization and combustion processes of the gel.
