Research on the strong transient process of the secondary air system in the Aero-engine based on the network method

Abstract A coupled model of engine mainstream way with secondary air system was established based on the network method. The change rule performance, parameters and axial force simulated when aero-engine sunk in shaft failure. dynamic could be forecast accurately analysis transient algorithm, also calculated. So simulation data can provided for engineering design, it help designer improve design. Moreover, its modular character allows integration further detailed air-system unites establishment more complex network. resultant tool is prospect studying characteristics mechanism Aero-engine system.
