"气溶胶火箭燃料" can be translated as "aerosol rocket fuel".
Here, "aerosol" refers to the colloidal or fine-particle dispersion state of the fuel (if applicable to the context where the fuel is in aerosol form), and "rocket fuel" denotes the fuel specifically used for rockets. If the term emphasizes the fuel's properties in an aerosolized state for rocket propulsion, this translation is appropriate.
If the context is more specialized (e.g., referring to a specific type of aerosolized propellant system), additional terms like "aerosol-based propellant" or "aerosolized rocket propellant" might also be used, but "aerosol rocket fuel" is a concise and generally understandable option.
