Abstract
An introduction of 5.5 m × 4 m anechoic wind tunnel in China Aerodynamics Research and Development Center (CARDC, in Mianyang) and some typical experimental results are presented. A C919 1:14 scaled aircraft model test shows that noise sources are mainly located at the landing gear, high-lift device, flap-wing joint points, slat-fuselage conjunction positions. And a 1:8 scaled high speed train model test shows that main noise sources are located at the first bogie and pantograph position.
