| Abstract: | By analyzing the principle of P2 pressure measurement device for the aeroengine ,its nonlinear model was established based on dynamic mechanical equation and dynamic flow equation. The dynamic linear model was established using steady-state linear method. The calculation method for designing the key element parameters in P2 pressure measurement device was presented according to steady-state balance relation. The simulation model of P2 pressure measurement devices was established based on Simulink, and validated by performance simulation. |
