Hot Ball and Socket Thrust Vector Control

摘要

Two 7-in. throat diameter hot ball and socket TVC nozzles were designed, fabricated and assembled by CSD for test on the AFRPL SLSH test motor. The first, tested 8 February 1979, experienced an average pressure of 1355 psia over a 60 sec duration with a 90% solids 21% aluminum HTPB propellant. Failure of the 3D C-C exit cone and loss of TVC occurred at 18.7 sec. Up to the time of failure, 16-deg of TVC travel was accomplished. The ball/throat survived the remainder of the firing duration.
