飞机燃油系统管路冲击压力问题的研究

Study of impactive pressure in pipes of aircraft fuel system

伴随计算机仿真技术的应用,管道冲击压力分析的方法和手段越来越丰富,使得在冲击压力计算方面更加方便和直观。对飞机燃油系统有压管道冲击压力(在民用水利系统称为水击)产生的原因及造成的危害进行了初步分析,介绍了几种冲击压力的分析计算方法,并指出某型飞机燃油系统管道可能出现的冲击压力及产生的故障,提出了防止冲击压力发生的措施。

This paper makes a preliminary analysis of the reasons and dangers of impactive pressure in compressive pipes of aircraft fuel system, and introduces several analytical computing methods. The possible impactive pressure and its malfunction, and the measures of avoiding impactive pressure are presented. With the application of computer simulation technology, there are more and more methods to analyze impactive pres- sure in pipes, so that the numerical simulation of impactive pressure is getting more convenient and intuitive.
