This paper presents a comparative analysis of aircraft acoustical performance based on the definition of a noise performance indicator called ENSA (equivalent number of standard aircraft). ENSA methodology is based on the choice of a standard aircraft, then ENSA’s values are obtained by comparing the generic aircraft’s performances with the standard aircraft’s performances. The performance evaluation is performed by analysing for each aircraft the equivalent number of standard aircrafts movements generating a noise level corresponding with one standard aircraft movement. This comparative analysis permits the evaluation of aircraft noise performance by comparing the ENSA values for different aircrafts.

Abstract

This paper presents a comparative analysis of aircraft acoustical performance based on the definition of a noise performance indicator called ENSA (equivalent number of standard aircraft). ENSA methodology is based on the choice of a standard aircraft, then ENSA’s values are obtained by comparing the generic aircraft’s performances with the standard aircraft’s performances. The performance evaluation is performed by analysing for each aircraft the equivalent number of standard aircrafts movements generating a noise level corresponding with one standard aircraft movement. This comparative analysis permits the evaluation of aircraft noise performance by comparing the ENSA values for different aircrafts.
