Bipropellant

A bipropellant is a type of rocket fuel system that uses two separate substances—usually a fuel and an oxidizer—that are stored separately and combined in the engine to produce combustion. This setup allows for more control over the engine's performance, efficiency, and storage safety. Common bipropellant combinations include liquid oxygen (oxidizer) with kerosene or liquid hydrogen (fuel). When mixed and ignited, they generate the high-energy output needed to propel spacecraft or rockets through space. The use of two components provides better performance and management of the combustion process compared to single-component systems.
