Abstract: In this paper,a method for converting the ground test results to the vacuum parameters of the rocket engines is presented.This method is featured by transforming directly from ground test results to vacnum performance parameters. And therefor, it will save the enormous cost of the vacuum simulation tests. This method is compared with the test results on one vacnum test stand-GS-1.The valia-tion of this methocdis confirmed
