民机飞行管理系统建模与仿真实现

飞行管理系统的建模与仿真在民机飞行模拟器的研制中具有重要意义。研究了飞行管理计算机系统(FMCS)的建模。FMCS的功能通过飞行管理计算机(FMC)和控制显示组件(CDU)实现。基于Visual C 编译环境开发了CDU操作界面,可进行数据输入与飞机状态监控。建立了FMC的导航数据库和性能数据库,规划了飞机水平飞行轨迹,完成了侧向飞行控制。最后基于飞行手册给出的飞行剖面数据设计了次优垂直轨迹。仿真结果表明,水平轨迹规划算法切实有效。

Modeling and Simulation of the Civil Flight Management System

Modeling and simulation of the civil flight management system are very important in a civil flight simulator.The flight management computer system(FMCS) was studied.The function of FMCS was completed by the flight management computer(FMC) and the control display unit(CDU).The display interface of CDU was developed based on Visual C programming environment.The initial data could be input and airplane state could be monitored through CDU.The navigation database and performance database were designed.Airplane horizontal trajectory was planed to control the lateral flight.The suboptimal vertical trajectory was designed based on flight data given by the flight manual.The result shows that the lateral algorithm is right.
