大型民用运输机噪声航迹及其仿真研究

A Large Civil Transport Airplane Noise Flight Path and its Simulation

噪声是民机型号适航合格取证的一项重要指标,噪声航迹是噪声合格审定的重要环节。本文讨论大型客机噪声合格审定基准噪声航迹及其计算。首先明确当前噪声航迹的定义,接着提出一种满足当前适航条例的民用运输机噪声航迹计算模型,最后给出算例分析,并指出未来研究的方向。

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.
