The cooperative attack of clustered aircraft can increase the overall combat effectiveness, however, the dense flight of aircraft faces the flight safety problem caused by the wing wake vortex. Aiming at the aerodynamic coupling effect of the wake vortex in the process of cluster cooperative attack, which can cause the flight safety problem caused by the neighboring aircraft generating too large induced rolling moment, a cooperative attack strategy under the effect of wing wake vortex that can meet the safety constraints of the flight of the aircraft cluster is proposed. A dangerous area model of the wing wake vortex effect during the dense flight of aircraft clusters is established, and the induced speed of the wake vortex and its resulting induced roll moment law are analyzed, on which a wake vortex dangerous area avoidance maneuver strategy based on an improved artificial potential field repulsive function is designed. Based on the consistency error variable of the estimated attack time, the distributed time cooperative guidance law is designed, which ensures that the attack time of all the aircraft can reach the consistency within a finite time, and give a stability proof for the attack time error of the system based on the Lyapunov stability theory. The simulation results show that the proposed cooperative attack strategy considering the flight safety constraints of the wake vortex effect can effectively reduce the influence of the wake vortex interference during the dense flight of the vehicles, which not only ensures the safety of the flight of the aircraft cluster, but also ensures the temporal and spatial consistency of the cooperative attack of the cluster.
