| Abstract: | In order to find the reason which affects the pressure-establishment stability of the re- lief valve and obtain the stable pressure-establishment process at outlet of the relief valve, the starting characteristics of a pneumatic system used in some propulsion system were researched by means of system simulation method and relevant tests. The result shows that the pressure stability behind the re- lief valve depends on the diameter of the pipe behind this valve and damping area inside this valve. |
