Abstract:

Aerial environment spectrum of aircraft structure is the important part of the service environment spectrum of airplane. In this paper, above all,the air polluter density are measured by air. Then, the horizontal area scale is approximately 200 km by the application of fuzzy set theory and the high extent is approximately 2 km. At last, the distributing law of polluter density with the height is studied by SPSS and the forecast model is gained. The forecast results are in better agreement with the measured results.
