Severe weather is the main cause for the delay of transport aircraft,rerouting strategy is an effective way to reduce delays,multi-aircraft path planning is the key point for rerouting.For many flights delay caused by severe weather,this paper presents artificial potential field method for multi-aircraft rerouting path planning.Traditional artificial potential field model is established according to the aircraft by gravity force and repulsion force,and different rotation control force between aircraft and aircraft,aircraft and severe weather is introduced to avoid local minimum value during rerouting.Simulation result shows that the path planned by improved artificial potential field method is shorter and smoother,and no large angle turning and repeated shocks,and the computational efficiency is improved by 33%.
