全任务飞行模拟机TCAS系统设计与实现

Design and Implementation of TCAS for Full Flight Simulator

提供了一种交通警戒及仿真系统(TCAS)在全任务模拟机中的设计方法。TCAS系统模型完全依据载机信号交联方式进行设计,充分考虑来自载机大气数据、导航、液压、近地告警等系统输出对TCAS系统工作模式、自动灵敏度选择及告警输出抑制的影响。入侵飞机的模型除常规空间运动算法还设计应答机类型,二者共同决定了载机能够提供的TCAS交通警告(TA)及决策建议(RA)范围,并且清晰定义了触发交通及决策的条件。为营造逼真交通场景,系统采用IData绘图软件绘制VSI显示页面,提供语音告警,优化可视范围内的入侵飞机参数并输出给视景系统进行显示。仿真模型已多次在高等级训练模拟器及工程模拟器得到验证。

Design methods for TCAS were provided.TCAS system’s model was designed completely depending on onboard part’s signal linkage mode,completely considering the affect on TCAS’s working mode,auto-sensibility selection and warning output restraining caused by output from onboard part’s ADS,navigation,hydraulic,GPWS and so on system.For intruding aircraft mode,except the conventional spatial motion algorism,the transponder type was designed,both of them jointly decided the onboard part to provide TCAS’s TA and RA range,clearly defined conditions to trigger TA and RA.In order to create realistic traffic scenario,VSI display page made by IData software was to provide voice warning,and the optimized parameters of intruding aircraft in visible range were sent to visual system to display.Simulated model has been verified on high-level training simulator and engineering simulator for many times.
