chemical propellant

Chemical propellant refers to substances that produce gas through chemical reactions when ignited, creating thrust that propels rockets and other vehicles. In simpler terms, when these materials burn, they release hot gases that expand rapidly, pushing against the engine's nozzle. This reaction allows rockets to launch into space or deliver satellites and payloads. There are various types of chemical propellants, including solid and liquid forms, each with its own advantages and applications in aerospace and military technology. The effectiveness of a propellant is often measured by its energy content and efficiency in producing thrust.
