摘　　要：为了减少飞机噪声排放对机场周围居民区的影响,研究了典型的进离场飞行程序。结合民用航空器运动模型和性能模型,建立了航迹模型。在研究飞行程序噪声评估方法的基础上,选取了合理的飞行程序噪声评价指标,提出了基于航迹分段模型的飞行程序噪声评估方法。以西安咸阳国际机场的进离场程序为例,选取B737—300机型进行仿真验证,绘制出了噪声等值线图。结果表明,该方法具有可行性,能够提高飞行程序噪声评估的效率,具有一定的参考价值。In order to reduce aircraft noise emissions on the impact of residential areas around airports, the typi- cal approach and departure flight procedures are studied. Combined civil aircraft motion model and performance model, trajectory model is established. With noise evaluation methods of flight procedures studied, appropriate noise evaluation index of flight procedures is selected. Noise evaluation methods of night procedures based on traj- ectory segmentation model are proposed. Approach and departure procedures of Xian International Airport is chose for an example. B737-300 is selected for simulation with drawing out the noise contour maps. The results show that this method is feasible and can improve the efficiency of the noise evaluation. The method is of valuable refer- ence.
