Liquid-propellant rocket - Wikipedia
Bipropellant liquid rockets use a liquid fuel such as liquid hydrogen or RP-1, and a liquid oxidizer such as liquid oxygen. The engine may be a cryogenic rocket engine, where the fuel and oxidizer, such as hydrogen and oxygen, are gases which have been liquefied at very low temperatures.

May 13, 2021 · Liquid rocket engines are used on the Space Shuttle to place humans in orbit, on many un-manned missiles to place satellites in orbit, and on several high speed research aircraft following World War II. In a liquid rocket, stored fuel and stored oxidizer are pumped into a combustion chamber where they are mixed and burned.
Liquid rocket engines are either mono-propellant or bi-propellant. Mono-propellant engines either use a straight gaseous system or employ a catalyst to decompose the propellant in an exothermic reaction.

Nov 20, 2023 · Liquid rocket engines are used on the Space Shuttle to place humans in orbit, on many un-manned missiles to place satellites in orbit, and on several high-speed research aircraft following World War II. In a liquid rocket, stored fuel and stored oxidizer are pumped into a combustion chamber where they are mixed and burned.
ESA - Solid and liquid fuel rockets - European Space Agency
A modern solid fuel rocket has a specific impulse of up to approximately 2500 N s kg-1 whilst a good liquid fuel rocket can produce up to 4500 N s kg-1. It is common practice to take a shortcut in the units, at ground level one kg of propellant weighs a little under 10 N and these two figures are cancelled out.
Using state-of-the-art techniques such as structured light scanning and 3D printing to translate an existing F-1 engine into a full-fidelity CAD model, Marshall’s liquid propulsion experts are examining ways to build on the significant investment of the Apollo Program to reduce costs and improve performance of the SLS.

Liquid rocket engines, or LREs, are one of the more popular rocket propulsion systems in use today. Most current engines utilize a bipropellant configurationin which fuel and oxidizer are stored in separate tanks.
Liquid Rocket Engines: Propulsion, Fuel Types | Vaia
Liquid rocket engines are a type of rocket engine that uses liquid propellants for thrust. Unlike solid rocket engines that use a solid propellant, liquid engines have several advantages, including the ability to control and shut down the engine during flight, making them a preferred choice for manned missions.
Liquid air cycle engine - Wikipedia
A liquid air cycle engine (LACE) is a type of spacecraft propulsion engine that attempts to increase its efficiency by gathering part of its oxidizer from the atmosphere.A liquid air cycle engine uses liquid hydrogen (LH2) fuel to liquefy the air.. In a liquid oxygen/liquid hydrogen rocket, the liquid oxygen (LOX) needed for combustion is the …
