Oxidizer. Pumps carry the fuel and oxidizer. The combustion chamber mixes and burns the two liquids. Combustion product gasses enter the nozzle through a throat. Exhaust exits the rocket. A liquid-propellant rocket or liquid rocket uses a rocket engine burning liquid propellants. (Alternate approaches use gaseous or solid propellants.)
Non-hypergolic propellants that have been most commonly used are liquid oxygen, alcohol, kerosene, and liquid hydrogen. Liquid rocket engines differ greatly depending on mission, materials of construction, and launch vehicle design.
RL-10 is an early example of cryogenic rocket engine. Rocket 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.
15 kwi 2016 · When the propellant is ignited, the hydrogen reacts explosively with oxygen to form: water! Elementary! 2H2 + O2 = 2H2O + Energy. This “green” reaction releases massive amounts of energy along with superheated water (steam).
20 lis 2023 · In a rocket engine, fuel and a source of oxygen, called an oxidizer, are mixed and exploded in a combustion chamber. The combustion produces hot exhaust which is passed through a nozzle to accelerate the flow and produce thrust.
Combustion (very lean or very rich to limit temperature) Use the fuel from regenerative cooling. Turbine inlet temperature is typically around 800-850 K. Staged combustion cycle is more efficient than the gas generator cycle (older systems such as F1 use the gas generation cycle).
