【摘要】 飞行模拟器是典型的人在回路的仿真系统,是采用地面模拟设备模拟飞机在空中飞行的重要装置,它已经成为当今国际航空界普遍采用的训练飞行员的最有效的手段。航空仪表系统作为飞行模拟器中的重要组成部分,提供给飞行员关于飞机状态和飞行特性等相关信息。它影响着飞行模拟器的逼真性,是决定飞行模拟器仿真度和先进程度的重要技术指标之一。本着提高国内飞行模拟器系统的研制水平,推动飞行事业发展的目的,由中国民航系统专题立项,哈尔滨工业大学和中国民航学院确定了联合研制开发飞行模拟器系统的课题方向。本文是该课题方向的子课题,对飞行模拟器仪表系统开发的相关技术进行研究。计算机技术以及相应电子技术的高速发展,以及高度集成机载电子设备信息的多功能虚拟仪表系统出现,改变了以往飞机座舱中仪器仪表纷繁复杂的布局,使得飞行员能快速获得飞行信息,从而更加有效地操纵和管理整个飞行系统。本文侧重于对开发虚拟航空仪表系统软件的研究。通过对整个虚拟航空仪表系统的需求分析,找到作为飞行模拟器虚拟航空仪表系统的自身特点,明确虚拟航空仪表系统和整个飞行模拟器及其它子系统之间的数据关系,结合航空仪表系统的实际应用确定虚拟航空仪表系统的功能要求和性能要求,确定虚拟航空仪表系统开发的整体方案和流程,最终开发整个飞行模拟器虚拟航空仪表系统。开发工作主要集中于在PC机上通过专业航空仪表开发软件VAPS Designer进行虚拟仪表的外形设计;通过增强转换网络模块ATN设计内部逻辑程序;采用C编程语言实现虚拟航空仪表系统内部的通讯及应用VC++进行虚拟仪表与外部通讯接口程序的开发;网络通讯采用UDP/IP通讯形式。配合其他子系统共同搭建飞行模拟器演示系统;通过整个系统的联调测试虚拟航空仪表系统的各项功能和性能指标;通过通讯仿真检测虚拟航空仪表系统的响应时间及网络延迟等。本文总体是对飞行模拟器仪表系统实现方法的初步探索,为飞行模拟器虚拟航空仪表系统的进一步开发打下基础的作用。涉及到虚拟仪表系统开发流程中一些相关技术问题,对其它同类仪表系统的开发也有一定借鉴意义。更多还原

【Abstract】 Flight simulator is a typical human-in-the-loop simulation system and an important device for simulating the flight’s flying using ground device. As an effective method for flight training, it has been widely used in today’s international aviation industry while the aircraft Instrument System which is used to display the airplane data condition and flight parameter is an important component of the flight simulator. Therefore it can influence the fidelity and variety of flight training, and is one of the important criteria for determining whether a flight simulator is advanced.For the purpose of improving the development level of the traditional flight simulator, and the quest for pushing our country’s aviation forward, the CAAC decided to embark into the research direction of developing the simulator, and entrust both the Harbin Institute of Technology and Civil Aviation University of China to complete it. This paper is a part of this research direction. Some techniques related with the development of the Virtual Aircraft Instrument System in flight simulator have been studied here. It also researches on some methods to successfully complete the system and ensures efficient system operation and hand over at the right time.The fast development of computer science and electron technology make the appearance of Virtual Aircraft Instrument System that highly integrates the digital information from airborne devices possible and the cockpit layout could be easily changed while the pilot can get flight information more quickly and control the aircraft more efficiently. This paper lays much emphasis on the research and development of the Virtual Aircraft Instrument System software. It has conducted an analysis of the Virtual Aircraft Instrument System, finds out the characteristics of the system in flight simulator, and makes clear the data relationship between the Virtual Aircraft Instrument System and other subsystems in flight simulator,including the function request as well as performance request for the system.With professional software VAPS design the appearance of Virtual Aircraft Instrument uses ATN (Augment Transition Network model) to develop the更多还原
