Flight Path Optimization And Conflict Resolution Based On The Flight Performance

With the rapid development of China’s economy. Because of civil aviation is fast, flexible,international, safe and comfortable, people will choose the aircraft as their traffic tools more and more.So the air traffic is becoming more and more crowded, so how to reduce flight cost and ensure flightsafety with the increase number of the aircraft in the same controlled airspace is very important toairlines.The study is mainly based on computing the flight performance. The original data (atmosphericcharacteristics, aerodynamic characteristics and engine characteristics, etc) of aircraft flightperformance and the equations of motion of mass are firstly introduced. Then, the methods ofcalculation of aircraft flight’s performance are introduced. At the same time, codes are developed tocalculate flight’s performance for varieties of aircraft. According to the software’s results, we couldfind out the economic flight profiles. Besides, the theory of optimal control is used to derive theoptimization equation of aircraft’s longitudinal flight profile. The global optimization has beenachieved with a particle swarm optimization algorithm, and has realized the goal of an optimal costtrajectory.From the aspect of conflict detection and resolution, this paper firstly introduces the relatedconcept of conflict detection and resolution. Then, according to the requirements of conflict resolution,the methods of changing course and adjusting speed are used to resolve the conflict. Meanwhile, thecost of conflict resolution is calculated. At last, considering the requirements of conflict resolution, theflight profile is optimized to a further level and quasi-optimal results of safe and economical flight areobtained in the paper.
