WebOct 15, 2024 · Gas-generator or open-cycle engines such as SpaceX’s Merlin engines use a turbopump assembly consisting of a preburner, a turbine, and two pumps. The preburner is a mini rocket engine that uses a portion of the fuel and oxidizer mixture to spin the turbine and deliver rocket fuel and oxidizer into the combustion chamber by controlling the pumps. WebApr 28, 2024 · The simplest form of a rocket engine just stores some sort of propellant in a tank at high pressure. Then, open a valve, and let that high pressure flow out through the engine. This is the basis of cold gas thrusters. As the name suggests, these engines run cold, meaning that there is no chemical reaction or combustion taking place.

The engine casing is a cylinder made of heavy cardboard which contains the nozzle, propellants, and other explosive charges. At the right side of the engine is the nozzle, a relatively simple device used to accelerate hot gases and produce thrust. A rocket engine is generally throwing mass in the form of a high-pressure gas. The engine throws the mass of gas out in one direction in order to get a reaction in the opposite direction. The mass comes from the weight of the fuel that the rocket engine burns.
