民航飞机平视指引系统仿真平台的设计与实现
|
摘要
针对民航飞机平视指引系统(HGS)的设备研制及该设备在飞机上加/改装的技术验证问题,设计了HGS系统半实物仿真平台。通过对全飞行阶段HGS工作模式和数据接口的分析,建立了HGS系统交联激励仿真模型,设计了基于真实航电总线的HGS系统仿真器和飞行参数激励器,实现飞机起飞、爬升、巡航、下降、进近、着陆的全过程动态仿真,完成了系统的集成测试。数据分析结果表明:所设计的仿真器满足HGS系统仿真验证的需求。
In view of the development of the head-up guidance(HGS) equipment for civil aviation aircraft and the technical verification of its modification on aircraft, a hardware-in-the-loop simulation platform for HGS system is designed. Through the analysis of the HGS working mode and data interface in the whole flight phase, the simulation model of the HGS system cross-link excitation is established, and the HGS system simulator and flight parameter exciter based on real avionics bus are designed. The dynamic simulation of the whole process of the takeoff, climbing, cruising, descending, approaching and landing is realized, and the integrated test of the system is completed. Data analysis results show that the designed simulator meets the requirements of the HGS system simulation and verification.
