    Abstract
  • Aiming at the conflict resolution problem among several aircrafts under fixation airway, the flight strategy of changing course was proposed, and the optimal conflict resolution models under free flight and fixation airway were compared. Aircraft performance and airway space were taken as constraint conditions, the conflict resolution time was taken as objective function, optimal control theory and differential equation were used, and the total conflict resolution times under different initial conditions were computed. Computation result shows that while the resolution endpoint of aircraft changes from (80, 0) to (65, 0), the total conflict resolution time reduces 32 s. While the resolution speed of aircraft decreases from 833 km·h-1 to 759 km·h-1, the total conflict resolution time increases 12 s. While the initial position of aircraft increaes from (20, 0) to (29, 0), the total conflict resolution time only increases 2 s. The resolution endpoint and resolution speed of aircraft have great influence on the conflict resolution time, but the initial position of aircraft has little influence on the conflict resolution time.
