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 2-3 months. Weight savings for the boss are about 20-40%. A composite polar boss which attaches closures 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 closure to be attached thereto. The materials of the boss are selected to permit a service temperature of 350 degrees F.
