摘要
航空仿真仪表是飞行模拟驾驶舱的重要组成部分。常规航空仪表改装方法开发难度大、维护成本高。研发一种能数据交换、对航空仪表外观、仪表显示和人的操作模拟的航空仪表仿真方法,对于提高航空仪表仿真系统集成度和改进其逼真度,具有重要意义。通过三维数模设计和加工实现航空仪表外形仿真,基于GLFW框架进行仪表图形化仿真,基于AVR单片机设计了硬件电路,实现了信号实时检测和指示灯的驱动。采用ASCII码报文实现仿真仪表面板硬件与仪表仿真程序的数据交换。经直升机飞行训练器装机实验测试,仿真航空仪表的外观、指示和操作响应与机载航空仪表接近,达到设计要求,有效提升了仿真度,降低了研制成本,对于研制飞行模拟训练设备具有重要意义。
Aviation simulation instrument is an important part of flight simulator. Conventional aviation instrument refitting method is difficult to develop and high maintenance cost. A simulation method is developed, which can exchange data and simulate the aviation instrument in appearance, display and operation. There are great significance for improving the integration and fidelity of aviation instrument simulation system. Digital design and CNC are used to make the aviation instruments panel and bezel; GLFW framework is used to render the graphical aviation instruments; hardware circuit is designed based on AVR MCU to realize real-time signal detection and lamp driving; ASCII code message is used for data exchange between simulation instrument panel and instrument simulation program. Through the test of helicopter flight trainer installation, the appearance, indication and operation response of the simulation aviation instrument is close to that of the airborne aviation instrument, which meets the design requirements, effectively improves the simulation standard and reduces the development cost. It is of great significance for the development of flight simulation training equipment.
