Abstract:

To alleviate the effects of aircraft noise effectively and choose the aircraft type which has lower noise, according to characteristics of a domestic airport noise monitoring data, this paper selected The Grey Relational Analysis of B-Mode that both has proximity and similarity to analyze the same flight with six kinds of aircraft’s noise monitoring data at the airport in a month. Moreover, according to the need of the research problem, it designed dimensionless processing method which optimized the noise monitoring data weight, improved The Grey Relational Analysis of B-Mode and calculated the each aircraft noise date and the optimal noise data’s correlation, then selected the needed low noise model. The results showed that the improved Grey Relational Analysis of B-Mode was suitable for the selection of low noise aircraft, and the analysis results were consistent with the actual, besides, the B733 models could mostly satisfy the conditions of low noise at the airport.
