ABSTRACT:
An apparatus is described for sealing segment joint crevices is a segmented, solid rocket motor comprising, one or more O-rings or gaskets and associated seating channels, said O-rings being adapted to be seated into the joint crevice outwardly, except the outermost O-ring which is adapted to seat inwardly into the joint crevice.
A method is described for seating said O-rings or gaskets comprising, applying a sequence of pressure evacuations, or of pressure excesses and one pressure evacuation, to the joint crevice between the pairs of O-rings through vent access ports, and then sealing off the vent ports.
