liquid propellant

Liquid propellants are fuels used to power rockets, consisting of liquids that combust to produce high-speed gases. They typically include a fuel (like liquid hydrogen or kerosene) and an oxidizer (such as liquid oxygen), which together undergo a controlled chemical reaction to generate thrust. Using liquids allows for precise control of engine thrust and the ability to shut down or restart the engine if needed. Liquid propellants are essential for spacecraft and missile propulsion systems due to their efficiency, scalability, and the ability to modulate power during flight.
