Applying the complex network theory, this paper studies the cascading failure invulnerability of airspace sector network at the system level, and proposes an optimization strategy to improve the failure resistance of airspace sector network cascade. First of all, the cascading failure model of sectors network is proposed, and the load and capacity of sectors network nodes are defined. The progress of cascading failure is analyzed, setting the critical threshold and sectors abnormal rate as the failure measurement indicators. Then, considering the operation characteristics of the control sector, two optimizing methods have been proposed:the adjacent load redistribution strategy based on the residual capacity of the nodes and the local load redistribution strategy. Based on the results of the simulation analysis, the local load redistribution strategy is proved to significantly boost the cascading failure invulnerability of sectors network.
