Web4 Mar 2024 · Chemical rockets burn fuel and oxidizer inside a combustion chamber. This imparts an enormous amount of heat to the gases, causing them to expand rapidly – in other words, an explosion occurs. In a rocket engine, this explosion is occurring continuously as fuel and oxidizer are pumped in. WebThe problem is that a simple rocket uses only the pressure difference between the combustion chamber and the ambient pressure outside to drive the rocket forward: The …
