Engine thrust chamber design method and engine thrust chamber

The invention discloses an engine thrust chamber design method and an engine thrust chamber, and belongs to the technical field of space.The engine thrust chamber design method comprises the steps that the number and the layout mode of engines are determined according to the design requirement of a final-correction attitude control power system, and performance parameters of the engines are determined; the control requirement of the final correction attitude control power system is matched with performance parameters of the engine, and the flow range of propellant entering the engine and the chamber pressure range of a thrust chamber of the engine are determined; determining an injection scheme and a profile scheme of an engine thrust chamber; simulation calculation is conducted on the engine thrust chamber, and whether the performance of the engine thrust chamber meets the requirement or not is verified. According to the invention, the overall requirement of the final correction attitude control power system
