摘要
为揭示复杂低空混合飞行态势中蕴含的安全特性,本文从复杂低空环境特点、航空器个体异质行为特征出发,构建了低空飞行行为模型;运用Agent技术,Net Logo平台构建了复杂低空混合飞行态势仿真环境,仿真分析了飞行量、平均速度、飞行冲突等特性参数之间的相互关系及其影响规律.研究结果表明:飞行冲突随飞行量增加呈先缓慢增加,后急剧增加的趋势,随平均速度急速递增趋势,当飞行量达到80架次、平均速度约300 km/h时,低空飞行态势安全性和效率均较高;通航活动的混合比例和冲突探测距离对复杂低空飞行态势安全性具有明显影响,当混合比为3:2:4:1,冲突探测距离为4 km时,可显著提高飞行态势的安全性和稳定性.
In order to reveal the safety characteristics contained in mixed flight situation in complex lowaltitude airspace, in this paper, based on the environment characteristics of complex low-altitude airspace and aircraft individual heterogeneous behavior feature, low-altitude flight behavior models are built; and the complex low-altitude airspace mixed flight situation simulation environment is built using Agent technology and Net Logo tool, and then the relationship and influence rules of characteristics parameters such as flight volume, average speed, and flight conflict etc. are revealed. The research result shows that： with the increase of flight volume, flight conflict increases slowly and then increases sharply, meanwhile it has sharp increasing trend with the increase of average speed, the safety and efficiency of low-altitude flight situation will be higher when flight volume reaches 80 and average speed is about 300 km/h; the hybrid ratio of different types of aircraft and the distance of conflict detection are greatly impact on the flight safety, and the flight situation can be improved by setting the hybrid ratio 3：2：4：1, conflict detection distance 4 km.
