基于Matlab/Simulink的民机空调系统文氏管流量精度仿真分析

Civil Aircraft ACS Venturi flow Simulation and Error Analysis using Matlab/Simulink

文氏管是测量民用飞机空调系统组件进口流量的重要部件,其精度指标直接影响到组件进口流量的控制。本文通过Matlab/Simulink仿真的方式分析温度压力测量位置的不同对于文氏管流量计算精度的影响。

Venturi is an important equipment used to estimate the ACS inlet airflow on the civil aircraft. This paper compares the estimated airflow sensing errors resulted from using different sensing positions to obtain temperature and pressure sensor signals based on Matlab/Simulink.
