WebRocket engines need high mass flow rates of both oxidizer and fuel to generate useful thrust. Oxygen, the simplest and most common oxidizer, is in the gas phase at standard temperature and pressure, as is hydrogen, the simplest fuel.
Web1 One solution is the use of a solid fuel gas generator used to start the turbine and the turbo pumps. The solid fuel is only used for start, but the pressure and gas flow should continue when the solid fuel burns out and the liquid fuel takes over. – Uwe Aug 7, 2024 at 10:16 1 WebThe Five Primary Ways In Which A Rocket Engine Is Ignited As mentioned during the introduction, up to five distinct methods can be used to start a rocket engine, depending …
WebJul 25, 2015 · 20. For a large bipropellant rocket engine to fire safely and stably, the fuel and oxidizer have to mix very thoroughly at high flow rate and pressure before they ignite. Otherwise, there will be sputtering and popping, which is very bad at that scale. Also, in many engines, a "film" of unburned propellant flowing along the walls of the nozzle ...
