The three main elements are: FUEL, for solid or liquid engines. This is the part that actually burns. OXIDIZER, for both, as there is not enough oxygen in the fuel cell to cause combustion. Combustion causes expanding gasses and controlled release from the combustion chamber causes thrust. STABILIZER, mostly for solids, and used to maintain a consistent/even burn of the fuel.
