Kerosene Fuel Conversion System for Rocket Combustion Stability

The patent applies preliminary action by pre-vaporizing and pre-heating the kerosene propellant before it enters the combustion chamber. The fuel is vaporized in a separate vaporization chamber and then mixed with oxidizer, ensuring complete combustion occurs in the main combustion chamber. This preliminary preparation of the fuel eliminates incomplete burning while maintaining high specific impulse.

The patent applies segmentation by dividing the combustion process into separate stages and locations. Vaporization occurs in a separate chamber, mixing occurs in a dedicated mixing section, and combustion occurs in the main chamber. This spatial segmentation of functions prevents the coupling of vaporization and combustion processes, eliminating the pressure oscillations and combustion instability that would occur if all processes happened simultaneously in one chamber.

The patent introduces an intermediary vaporization chamber that acts as a mediator between the liquid kerosene feed and the combustion chamber. In this intermediate chamber, the large hydrocarbon molecules are vaporized and partially decomposed before entering the combustion zone. This intermediary step breaks down the complex molecules into smaller, more combustible fragments, ensuring complete combustion while stabilizing the combustion process by separating the complex molecular breakdown from the actual combustion event.
