Abstract: |
In order to achieve the long-term storage of divert and attitude control propulsion system, the feasibility research on application of fully-welded high-pressure pipeline is presented in this paper. The technologies of dissimilar metals welding, all position welding and general assembly, which is necessary for the fully-welded structure in divert and attitude control system, are analyzed. And the relevant prototypes have been made to prove the feasibility. |
