ABSTRACT:
Composite polar bosses applied in rocket motor cases have very desirable characteristics. The lead time for a boss can be reduced from 6-12 months to 4-6 months. Weight savings for the boss
ozzle assembly are about 20-40 percent. A composite polar boss which attaches nozzle assemblies to solid fueled rocket motor cases is disclosed. This polar boss is a carbonized fabrication which sits within a circumferential indentation within the motor case, and has a threaded inner circumference which permits the nozzle assembly to be attached thereto. The materials of the boss are selected to permit a service temperature of up to 3,200 degrees F.
