Liquid rockets are a type of rocket engine that use liquid propellants to produce thrust. These engines typically consist of two main components: a fuel and an oxidizer, which are stored in separate tanks. When combined in the combustion chamber, they ignite and create high-pressure gases that are expelled through a nozzle, propelling the rocket forward. One of the advantages of liquid rockets is their ability to be throttled, allowing for precise control of thrust during flight. This feature is particularly useful for missions involving satellites, space exploration, or human spaceflight, where adjustments in speed and altitude are often necessary.
