Abrasion of on-ff valve side for fuel system

摘要

Transmission on-off valve is an important component in the aircraft fuel system. It is directly related to the fuel supply security during the flight. Erosive wear is the main form of transmission on-off valve failure. it is said that Mathematical modeling of the dynamic characteristics of hydro-mechanical shut-off valves in typical aircraft fuel system, and the failure to model caused by Erosive wear.
