| Abstract: | In this paper,the reason and machenics of pressure surge are researched iniatially.A simple model of aircraft fuel pipelines is established,and then quantitative analysis of pressure surge caused by valve shut-off time and the pump's start-stop is especially made.Based on the analysis result,some concrete measures of controlling pressure surge are proposed. |
