  • 摘要:

    航空器连续爬升剖面的准确预测可以提高冲突探测的可靠性和离场排序的精确性。基于推力设置信息,提出航空器推力意图的建模方法。利用航空器的全能量方程,考虑风速向量与温度信息,提出考虑推力意图的航空器连续爬升垂直剖面的预测方法。利用快速存取记录器(QAR)数据,进行多案例的对比分析,以QAR每一数据帧为采样点,重点对预测剖面的真空速、高度和燃油流量等进行误差分析。考察不同预测方法,对比到达爬升顶点(TOC)的时间和距离的误差。结果表明:采用所提预测方法可以将到达TOC时间平均绝对误差控制在1 min内;与不考虑推力意图的预测方法相比,可以降低到达TOC时间平均绝对误差约52%。
