Solid Rocket Booster Starter System for Tactical Missile Turbojet Engines

The turbojet engine starter system utilizes the pressure of the solid propellant boost motor to pressurize a fluid contained in a bladder tank. The increase in fluid pressure ruptures a diaphragm containment seal allowing the fluid to flow through a boost motor/heat exchanger where the high pressure fluid is heated to high temperature. The heated fluid is used to spin-up rotors and to ignite the burner of the turbojet engine. The thermal energy input to the heat exchanger is from the products of combustion of the solid booster motor.
