Series: ASM Failure Analysis Case Histories
Volume: 2
Publisher: ASM International
Published: 01 December 1993

... the thrust vector control system of the Space Shuttle solid rocket booster ( Fig. 1 ). The poppet valve assembly consists of an AM-350 bellows welded onto an AM-355 poppet that acts as the sealing surface. The valve is normally closed (shut off), so that in an inactive condition no hydrazine fuel is allowed...
