More Information
Summary:A low cost easily installed and reliable weather seal for the nozzle throat of a solid propellant rocket motor which uses an aft end ignition system. The igniter cartridge, known per se, which is located in the throat of the rocket motor is provided with an elastomeric O-ring in the base of the cartridge thus sealing the gap between it and the inside surface of the exit cone of the nozzle. This structure not only provides an effective weatherseal but also provides a convenient means of positively retaining the igniter cartridge in place.
