基于改进动态窗口法的低噪声离场航迹规划研究OA

With the rapid development of civil aviation industry,green aviation has gradually become the focus of people's attention.Taking into account factors such as aircraft performance,noise impact,and atmospheric environ-ment in the terminal area,an optimization plan for aircraft departure trajectory has been proposed.Aiming at the problem that traditional Dynamic Window Approach(DWA)cannot effectively solve in aircraft departure trajecto-ry planning,an improved Dynamic Window Approach combined with aircraft performance is proposed.The aircraft departure performance constraints are constructed based on the requirements of Base of Aircraft Data(BADA)and Continuous Climb Operations(CCO).At the same time,the noise impact of aircraft departure is considered.The smaller the noise impact,the better the trajectory.Secondly,under the same research environment,the methods with different index weights based on the duration and area of influence are analyzed,and the methods with the smallest comprehensive impact are selected.Finally,based on the selected method,the performance parameters such as thrust,speed,and path angle of the departing aircraft are analyzed.The simulation experiment results show that the trajectory under the improved dynamic window method can meet the requirements of aircraft departure per-formance.
