未来航空运输需求预测表明，噪音等环境问题将进一步加剧，超出目前的水平。尽管可以使用集成噪声模型和联邦航空管理局的航空环境设计工具等工具进行详细的机场噪声建模，但由于用户可用的输入数量和模型的一般保真度水平，这些软件需要相对较长的设置和运行时间。需要一种快速、灵活且更简化的方法，将输入变量减少到关键的几个变量，并可以在几分钟内提供结果，以评估与新技术或预测需求变化相关的车队级指标。当前的低保真度方法仅计算由于整个机队组成的变化而导致的等高线面积的变化。这些方法无法解释轮廓的形状。本文提出了一种利用详细模型保真度的快速机场噪声计算模型。通过表演...
Future air transportation demand forecasts suggest that environmental concerns such as noise will be exacerbated beyond their current level. Although detailed airport noise modeling with tools such as the integrated noise model and the Federal Aviation Administration’s Aviation Environmental Design Tool are available, these software require relatively long setup and run times due to the number of inputs available to the user and the general fidelity level of the models. A rapid, flexible, and more simplified method that reduces the input variables to a critical few and can provide results in minutes is desired to evaluate fleet-level metrics with respect to new technologies or forecasted changes in demand. Current lower-fidelity methods only calculate a change in contour area due to changes within the overall fleet composition. These methods cannot account for the shape of the contour. This paper presents a rapid airport noise computation model that leverages the fidelity of detailed models. By performing...
