In this study,the characteristics of the aerodynamic noise generated from aircraft landing gear scaled model with 5% scaled model which have two wheels are investigated.Aerodynamic noise is measured with low-noise wind tunnel at Re = 1.7×10^5 based on the tire diameter and flow speed.Comparison of the results of the small scaled model and that of JAXA 40% scaled model are carried out.The aerodynamic noise characteristics which depend on effect of model scale and model shape from far field sound measurements at downward of the airframe are showed.
