某型飞机燃油系统交输供油功能实时仿真

使用Simulink对某型飞机燃油系统各部件建立了数学模型。模拟了当一侧油箱故障时的单油箱供油给双发的工作模式。给出了在该模式下油位高度变化等燃油系统关键数据。利用Stateflow模拟了燃油控制系统Central Core System(CCS)的控制功能,并基于MATLAB Real-Time Workshop(RTW)以及VxWorks实时操作系统建立了对此功能的半物理实时仿真系统。完成了对此供油功能的地面闭环测试,为飞机燃油系统建模与控制提供了参考。

Real-Time Simulation of the Cross-Feed Function of One Aircraft Fuel System

In this paper, the mathematic model of varies components of aircraft fuel system were built using Simulink, and the cross-feed mode, which supplies fuel from one tank to both engines when one of the two main tanks malfunctioned was simulated. Certain key data such as fuel height were presented in this mode. Function of Central Core System(CCS) was simulated with Stateflow, and based on MATLAB Real-Time Workshop(RTW) with VxWorks,an outstanding Real-Time Operate System, the Semi-Physical simulation of this function of fuel system was done. Such test has certain reference value for modeling and controlling of aircraft fuel system.
