Abstract

The braking system of the aircraft is an important subsystem of the aircraft's landing braking. Flapper-nozzle pressure servo valve is the key hydraulic component of the brake system. The goal of this paper is to establish the mathematical model of flapper-nozzle pressure servo valve, deduce the transfer function, and use the MATLAB/Simulink simulation platform to build a reliable and effective simulation model. It can support the parameter selection of the hydraulic components of the subsequent models of the brake system.
