Webof four solid rocket motor sections mated together using equally spaced pins. The segments are assembled using a series of field joints and factory joints (Figure-l). The field joint differs by incorporating a capture feature with an additional O-ring in the tang. This was developed for safety purposes as a result of the Challenger accident. WebThe revised field joint was introduced with the return-to-flight mission, STS−26 in September 1988, and there were no further problems with the solid rocket boosters. Subsequently, the field joint mating pins were lengthened and a retaining band added to improve the shear strength of the pins and increase metal part’s joint margin of safety.
