How a Solid Rocket Motor works?



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.
