Analysis on the Precooler Outlet Compensation Pipe Rupture of Civil Aircraft
摘要
This paper focused on the rupture problem of precooler outlet compensation pipe of civil aircraft, the design concerning was discussed. Based on the design proposal, aging mechanical from two aspects of temperature and high velocity sand dust flow were calculated and tested. Root cause of pipe rupture is identified and the result shows silicon rubber could not suffer high temperature up to 250 ℃ and velocity up to 150 m/s.
