| Abstract: | In order to lighten the weight of latch valve used in spacecraft propulsion system,the research is done on new nano Nd-Fe-B magnet by using theoretical,numerical and experimental methods.The result shows that the new nano Nd-Fe-B magnet has better performance than the old one.The latch characteristic of the latch valve made by the new magnet material has great superiority.Therefore,the latching valve can be more compacted and lighter. |
