hybrid rocket

A hybrid rocket is a type of spacecraft propulsion system that combines elements from both solid and liquid rockets. It typically uses a solid fuel core paired with a liquid oxidizer that is pumped into the combustion chamber. This setup allows for more control and safety compared to traditional solid rockets, as the fuel flow can be regulated or shut off. Hybrid rockets are used in research, suborbital flights, and some space launch applications because they offer a balance of safety, simplicity, and performance, making them a versatile option in rocket technology.
