摘要
基于不同的高等级模拟机空中交通警告与防撞系统(Traffic Alert and Collision Avoidance System,TCAS)冲突训练科目,抽象出飞行过程中十种典型入侵飞机模型,模拟空中可能出现的交通冲突,建立入侵飞机方位、高度、速度等参数的通用仿真计算算法,实现入侵飞机的动态模拟,并解算入侵飞机经纬度、绝对高度等信息用于视景系统显示。建立应答机仿真模型,模拟通过应答机询问获取入侵飞机识别码及高度信息的过程,然后根据获取的入侵飞机的位置、高度等参数,推测最接近点(Closest Point of Approach,CPA)及到达最接近点的时间,结合本机当前飞行高度及TCAS灵敏度,实现入侵目标威胁等级判断。当出现决策建议(Resolution Advisory,RA)级别冲突时,解脱决策算法给出解脱建议,最终输出入侵目标的信息和冲突解脱决策到指示记录系统仿真界面,实现交通信息提示和解脱建议的显示。经验证,仿真模型正确模拟机载TCAS系统工作逻辑,入侵目标的仿真计算可有效模拟空中出现的交通冲突、威胁等级判断及解脱建议算法,可满足模拟训练要求。
Based on different conflict training subjects of traffic alert and collision avoidance system(TCAS) of high level flight simulator, ten typical invading aircraft models during flight are abstracted to simulate possible traffic conflicts, and a general simulation calculation algorithm for intrusion bearing, position, altitude, speed and other parameters is utilized to realize the dynamic simulation of the intruders. Information such as the latitude, longitude, and absolute altitude of the intruder is calculated and used for visual system to display intruder aircraft in scene. Transponder’ simulation model is established to simulate the querying process getting the identification code and altitude of the intruders. Closest point of approach(CPA) and CPA time are calculated according to the position, altitude and other parameters of intruder, intruders threat level is judged considered on intruder’s altitude and TCAS sensitivity. When a resolution advisory(RA) level conflict occurs, the simulated resolution algorithm gives resolution advisory. Finally, the intruder information and TA/RA are outputted to simulation interface of indication system for displaying the traffic information and vertical resolution advisory. It is verified that the simulation model can simulate the working logic of airborne TCAS system, and the simulation of the intruder aircraft can effectively simulate the traffic conflicts which may occur in the air, the threat level judgment and the resolution advisory algorithm, which can meet the simulation training requirements.
