Abstract

This work presents a method to select parameters and use them in an index to identify the degradation level of an aeronautic valve of the type PRSOV (Pressure Regulator and Shutoff Valve), a valve of the bleed air system of aircrafts. This index function is to be used as an input to the valve controller reconfiguration as the valve presents degradation while ages. The monitoring of degradation rates can provide information to modify the controller parameters in order to increase the valve useful life, to allow maintenance services planning or even to prevent the system performance being meaningfully impacted by the valve aging. The sorts of degradation considered were: friction increase, charging orifice obstruction and venting orifice obstruction. The study was made based on the valve mathematical model, in which was possible to vary those degradations levels and verify how each one influences the model response. The hysteresis graphic morphology was analyzed and also the sensibility and robustness after disturbances in the inlet air pressure with the system in closed loop, where the objective was to identify a monitoring that could be realized with the aircraft in air. The results allowed the identification of the most recommended parameters to monitor and the evaluation of the valve degradation through them.
