Liquid propulsion
Liquid propulsion is a type of rocket engine that uses liquid fuel and oxidizer, stored separately, which are pumped into a combustion chamber where they ignite. This controlled burning produces a high-speed stream of gases that exit through a nozzle, generating thrust to propel the vehicle forward. It offers precise control over engine power and the ability to shut down and restart, making it ideal for space missions. Examples include engines using liquid hydrogen and liquid oxygen. Overall, liquid propulsion provides efficient, reliable, and adjustable thrust necessary for advanced space travel.
