单次飞行事件噪声等值线计算新方法的研究
The Study on New Method of Single Flight Contour Calculation
摘要
Abstract
To overcome the defects of stationing needs and the bothersome interpolation in current noise contour calculation for single flight event, a sub-function mathematical model is proposed.In this model, the aircraft noise contour of different flight path subsection is expressed as several sub-functions.This model has such advantages that stationing is not necessary and it is easy for programming and designing in the process of noise contours calculation.Using a certain type aircraft flight data, the noise contour is computed based on the sub-function model.And the result of computation is compared with that using the current noise contour calculation method.The relative difference between them is less than 1％.Thus, the validity of the new model is proved.This new model is worth promoting in evaluation of aircraft noise.关键词
