航路网络交叉处高密度交通形成的冲突是诱发管制员工作负荷的主要因素,合理的冲突解脱策略可以降低对保护空域的需求.针对典型2向交叉流结构,在分析横向侧移冲突解脱策略优势与不足的基础上,提出了更符合管制实际需求的基于2次航向改变的组合冲突解脱策略.首先建立了不受空域约束的组合策略数学模型.组合策略较横向侧移策略占用较少的机动缓冲空域.进一步建立了受空域约束的组合策略数学模型,通过仿真讨论了不同策略的空域资源可用率.初始偏置角与航迹交叉角存在复杂制约关系,其合理配置可缩小缓冲区范围,增加空域资源可用率.
Conflict of high-density traffic at the intersection of route network and network is the main factor inducing the workload of controller, and reasonable conflict resolution strategy can reduce the need of protecting airspace.According to the typical 2-way cross-flow structure, And based on the lack of control strategy, a combinatorial conflict resolution strategy based on two changes of heading is proposed, which is more in line with the actual control requirements.Firstly, a mathematical model of combinatorial strategy that is not subject to airspace constraints is established.The combined strategy is less maneuvering than the lateral strategy Buffer airspace.A mathematic model of a combination strategy constrained by airspace is further established and the availability of airspace resources of different strategies is discussed through simulation.The initial offset angle and the track crossing angle have a complex restriction relationship.The rational allocation can reduce the scope of the buffer zone, Increase the availability of airspace resources.
