Abstract: |
This paper expatiates spilth’s harm to SRM flexible nozzle during SRM test and sorts, as well as the reason that spilth is sorted and made. Based on a lot of practice, the methods for preventing, checking and eliminating spilth in thrust vector test of SRM flexible nozzle are presented. Some specific advices are given to design, craftwork, assembly and test of SRM flexible nozzle. |
