航空安全一直以来备受社会各界关注,其中安全间隔对于航路运行有非常重要的意义。为了合理分配航路间隔,减少航路拥堵,基于实际运行情况,将连续的飞机流作为研究目标,从宏观和微观角度建立了纵向间隔的计算模型,根据飞机流的跟驰效应,得出航路运行间隔的动态变化范围。在此基础上,提出了快速地对航空器进行间隔调整的方案。最后,以西安管制区的运行数据为例进行仿真,验证了模型的合理性,并分析了各因素对飞行流间隔的影响,调整方案可以较快地完成航路间隔的重新分配,为运行提供更准确的引导。

英文摘要：

The given paper is inclined to make a study of the longitudinal interval for the airplanes to keep away at the same height both from the macro-and micro point of view. In order to properly allocate the flying route interval and reduce the flying congestion in addition to the risk of flying contact,this paper takes the continuous flow safety of the airplanes as its study focus on account of the actual operation situation,for it can present the calculation model for the longitudinal separation from the micro and macro perspectives of the aircraft flow. In so doing,we have to work out the dynamic range of the route interval properly. As to the macro interval model,it should be established based on the number of aircraft and their speed distribution. The safety interval tends to be fluctuated in a greater range of different parameters. On the other hand,the micro interval model should be made more reasonable with its interval assessment by introducing the airplane to a proper position. Based on these models,the paper has also brought about the concept of the fast interval adjustment on the aircraft scheme. And,finally,we would like to take the operation data of Xi＇an air-control area as a case study sample for our simulation model. And,in this point,the results of our simulated study prove to be consistent with the situation in-situ. When the model was put into the qualification test,it has been proved rational.And,then,the model has been used to analyze the effects of various factors on the flight flow interval. Since the adjustment scheme can help to redistribute the route intervals promptly and efficiently,it can provide more accurate guide for the practical flying operations. Thus,the innovative scheme of the paper lies in taking a group of airplanes as a collective flying action,which sounds more reasonable for the assessment of the real route interval and totally different from most of its previous predecessors on the interval of the adjacent airplane. Solving the problem of the continuous intervals in the tw
