Research and modelling on performance database of flight management system

In order to investigate and exploit advanced flight management system with complete functions, provide applicable and reliable performance data for optimal trajectory search, data structure requirements of performance database of flight management system are presented, including the structure of aerodynamic data ,engine performance data and operation data. The whole authentic performance data is acquired by integrating the performance data of flight simulator in the second phase of 985 projects and the flight manual. Based on the former performance data, combining the thrust method, particle swarm optimization algorithm and the energy-state method, the performance data is transferred into equal energy-height curves which can be more applicable for optimal trajectory search. Based on the processed performance data, the performance model is built on the basis of Microsoft Visual C++ and MATLAB/SIMULINK. The running results of the flight management system program indicate the method used to exploit performance database of flight simulator prototype system is effective and feasible.
