为研究机场跑道、滑行道结构、机型比例对航空器起降间隔的影响,在分析跑道、滑行道运行方式基础上,细化航空器起飞、着陆占用跑道滑跑、滑行过程,定义航空器元胞尺寸和速度位置演化规则,构造航空器滑行元胞自动机模型。计算机数值模拟得到滑行道位置、机型比例、机型组合改变时,起降间隔、间隔标准差的变化趋势。仿真结果表明:滑行道距离跑道头越近,起飞间隔越小;滑行道接近着陆航空器减速滑跑结束位置时,着陆间隔最小;滑行道距跑道头450~800 m时,平均间隔最小为135 s,800~900 m时,间隔标准差最小为20.9;与全中型机相比,全小型机时平均间隔减少17.8%,间隔标准差减少42.3%。该模型能量化机型、滑行道位置等关键因素对起降间隔的影响,能为提高机场吞吐量提供技术支持。
In order to study the influence of airport runway, taxiway structure and aircraft model on the aircraft takeoff and landing interval, the paper analyzes the runway and taxiway operation mode, and elaborates aircraft take-off, landing occupancy runway sliding and taxiing process, defines the aircraft cell size And the evolution rule of velocity location, the cellular automaton model of aircraft taxiing is constructed. Computer numerical simulation taxiway position, model ratio, model combinations change, taking off and landing interval, interval standard deviation trends. The simulation results show that the shorter the taxiway is from the runway head, the smaller the take-off interval. When the taxiway approaches the landing position of the landing aircraft, the landing interval is the minimum. When the taxiway is 450 ~ 800 m from the runway, the average interval is 135 s , 800 ~ 900 m, the minimum standard deviation is 20.9; Compared with the mid-size machine, the average size of the full-size machine is reduced by 17.8% and the standard deviation of the interval is reduced by 42.3%. The model can quantify the influence of the key factors such as the type of taxiway and taxiway on the takeoff and landing interval and provide technical support for improving airport throughput.
