Trajectory Optimization of Aircraft for A Continuous Descent Continuous Procedure

In this paper, a Continuous Descent Continuous(CDO) trajectory optimization problem is considered. In this problem, the optimal trajectory of a CDO procedure is designed. First, the CDO trajectory optimization problem is formulated as multiple phase optimal control problems. Then, a trajectory optimization results for a CDO is given based on the pseudo spectral method, which guarantee the delay time costs, noise costs and fuel consumption minimum. Last, Simulations results and analysis are considered to verify effectiveness of the method.
