【摘要】 本文针对飞行管理计算机的水平导航功能展开了如下几方面的研究:首先根据飞行管理计算机水平导航系统的功能确定出了水平导航系统与飞行模拟器其它系统进行通讯的所有输入输出接口。然后分析水平导航功能的输入输出接口间的内部联系,并将输入输出接口按功能及内部联系进行模块划分,建立了水平导航系统的八个子模块,即导航台数据库管理子模块,FMC速度计算子模块,FMC位置计算子模块,导航台调谐管理子模块,无线电位置计算子模块,高度特性点计算子模块,水平制导子模块,航路管理子模块等。这八个子模块既相互独立又相互联系。接着分别对八个子模块的功能实现算法进行了深入研究,并给出了具体的实现算法。特别地,针对飞行管理计算机的侧向制导子模块,本文以飞机的动力学和运动学为基础,建立了飞机的侧向偏移数学模型,并结合状态反馈法和重定义输出变量法,确定出了飞机的侧向偏移控制律,完成了控制律收敛性的证明,给出了侧向航迹偏移和侧向航迹误差角的计算方法,最后还结合De Havilland Aircraft of Canada Ltd公司制造的单引擎、高翅、七座的金属飞机模型对飞行管理计算机的侧向制导功能进行了数字仿真。最后用C++语言,结合动态链接库技术,对飞行管理计算机的水平导航功能进行了总体程序设计,并完成了程序单功能测试和综合功能测试。更多还原

【Abstract】 Research on lateral navigation of flight management computer is done in this paper.First, according to the function of flight managent computer, all the input-output ports of lateral navigation system are analysed, through which to communicate with other systems of simulator.And then the internal relationship between all the input-output ports is researched, and they are divided into eight sub-models, which not only interrelate with each other, but also are independent, according to their functions and their internal relationship. The eight sub-models are database management of station model, FMC speed calculation model, FMC position calculation model, station tune and management model, radio position of aircraft calculation model, altitude property points calculation model, lateral control and guide model, route way management model.Further more, according to their functions, deep study of the arithmetic for all of the eight sub-models is done and their detailed arithmetics are presented also. Specially, aiming at the problem of aircraft’s lateral control and guide, based on aircraft’kinematics and dynamics equation, aircraft’s lateral excursion mathematic model is built up, and based on state feedback and redefinition output variable its control law is also proposed. Not only the astringency of the control law is finished to be proved and the detailed arithmetic for trajectory error and trajectory angle error is expressed, but a digital simulation is done also, combining a single engine, high- wing, seven seats, metal aircraft which was manufactured by De Havilland Aircraft of Canada Ltd.Finally, by using language C++ and combining the dynamic linkable library technology, the global lateral navigation system is programmed. And single function test and integrate function test for the lateral navigation program are also done.更多还原
