WebMay 4, 2024 · In normal internal combustion engines, you use extra fuel to cool the engine. Allowing it to run lean (more oxygen, less fuel) will cause it to run hotter. Fuel doesn't burn without an oxidiser. The rocket isn't made of oxidisers, so it's perfectly safe to use fuel as coolant. Oxidisers burn fuels. WebCooling the chamber, therefore, was critical to preventing the engine from destroying itself. The V-2's designers used two methods to cool the engine: regenerative cooling and film cooling. Regenerative cooling used the …
WebA pintle-based rocket engine can have a greater throttling range than one based on regular injectors, and will very rarely present acoustic combustion instabilities, because a pintle injector tends to create a self-stabilizing flow pattern. ... and provide fuel film cooling. The pintle pictured here is of this type. A pintle injector is shown ... WebThe need for fuel-film cooling is eliminated, which simplifies the injector design; Because only 2–5% of the total fuel flow is needed for transpiration and because no fuel-film cooling is needed, most of the fuel can be …
