Solid propulsion

Solid propulsion is a type of rocket propulsion where fuel and oxidizer are combined into a single solid substance, called a propellant. When ignited, this propellant burns in a controlled manner, producing hot gases that rapidly expand and are expelled through a nozzle to generate thrust. This method provides a simple, reliable, and powerful way to propel rockets or missiles without the need for complex plumbing or moving parts. Because the fuel is pre-loaded and stored as a solid, it is ideal for quick launches and applications requiring straightforward, robust propulsion systems.
