This paper mainly introduces a hybrid algorithm to solve vertical trajectory optimization problem during aircraft descent. According to the flap schedule of aircraft, the problem can be formulated as a multiple-phase optimal control problem. Pseudo-spectral method is used to discretize the continuous optimal control problem into nonlinear programming (NLP) problem. Then we adopt a hybrid method, namely...
4D trajectory generation is one the most fundamental functions in the airspace simulation system. Currently, most methods are based on partitioning of the flight. In this paper, a new 4D trajectory generation method is proposed based on historical radar data processing, which includes implementing the traffic flow theory to generate the initial state of each flight, and introducing the interacting...
With the increase of air traffic flow, aircraft conflicts and delays on hub airports have been complex and challenging in airport surface management for a long time. In this paper we propose a dynamic route optimizing model to decrease the conflicts on the taxiway and enhance the capacity of airport surface operation compared to the current operation mode. A ready-for-departing or just-arrived aircraft...
