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 purpose of the field-joint is to hold the four segments of the Solid Rocket Motor (SRM) together. It also functioned to seal hot gases of the burning propellant within the steel …
In 1988–1989, NASA was planning on replacing the post-Challenger SRBs with a new Advanced Solid Rocket Motor (ASRM) to be built by Aerojet at a new facility, designed by subcontractor, RUST International, on the location of a cancelled Tennessee Valley Authority nuclear power plant, at Yellow Creek, Mississippi (Yellow Creek Nuclear Plant). The ASRM would be slightly wider (the booster's diameter would be increased from 146 inches t… WebFeb 1, 1996 · Faulty O-rings, normally flexible and pliable, but frozen stiff by the cold weather, were identified as the reason for the Challenger explosion, which resulted in the loss of …
