摘要

介绍了在室外进行的螺浆飞机缩比模型的噪声测量试验

目的是验证改进的螺浆飞机声场模型

它可预测任意形状机身边界的表面声压分布。介绍了试验

噪声测量以及预测方法

预测和试验结果的比较表明得到了较满意的符合。

Abstract

An experimental research with a propeller aircraft scale model has been completed to obtain reasonably comprehensive data for validating its improved sound field model.Instead of the tests in anechoic windtunnel as abroad

the scale-model tests was accomplished in outdoor conditions.In the predicton of propeller noise in free field with the improved sound field model

the load data on the propeller blade surface were obtained from calculation of inverse problem.The measured results of sound pressure on the scale-model have been compared with that predicted by the improved sound field model in a reasonable agreement.
