| 摘 要： | 本文使用Ｙ１２飞机的１／３缩比模型桨进行了螺桨地面噪声试验，使用圆柱型缩比座舱模型测量了舱内声压。试验中发现时间平均增强法是去除地面湍流影响的有效方法，利用舱内传声器阵可以测量舱内声场分布，经改进，使用户外螺桨模型噪声试验来作为螺桨噪声预测结果的验证手段是可行的。

| Abstract: | Propeller ground noise test for the 1/3 scale model propeller of Y-12 aircraft has been taked. The sound pressure in cabin be measured by using cylindric scale cabin model. Time -average strengthen method is effective method for eliminating influence of ground turbulent flow. Sound field distribution on cabin may be measured by using microphone array. Improved, it is practicable that Dutdoor propeller model noise test be used to test and verify the prdiction result of propeller noise. |
