How a Solid Rocket Motor works?
- Heat sensitive charge of the initiating system is ignited by passing electric current through the embedded wire.
- The energy release system of igniter catches fire and delivers sustained heat energy to the propellant surface.
- Solid propellant which contains both oxygen and fuel burns and builds up pressure.
- Pressure stabilizes when rate of gas production equals rate of gas flow through the nozzle.
- Thrust is generated when hot gases pass through the nozzle.
