| Abstract: | Aircraft noise level is one of the aircraft airworthiness certification requirements.The calculation of noise flight path of civil transport jet aircrafts is an important step in the aircraft noise certification.This paper discusses civil transport airplane noise flight path and its simulation.The noise flight path is briefly introduced first,the definition of aircraft noise flight path is described,and an analysis of calculation cases is then given following addressing the calculation model of aircraft noise flight.Finally,some advices and further jobs about the noise flight path are proposed. |
