SRM (Solid Rocket Motor)
A Solid Rocket Motor (SRM) is a propulsion device that uses a solid propellant to produce thrust. When ignited, the combustion of the solid fuel generates hot gases that rapidly expand and are expelled through a nozzle, creating the force needed to propel a rocket or missile. The entire fuel is preloaded into the motor from the start, making it straightforward and reliable, with no need for complex moving parts or refueling during flight. SRMs are common in space launch boosters, missiles, and emergency escape systems because of their simplicity, robustness, and ability to provide high thrust quickly.
