The important specific properties of thechannel are the large test section (2. 0 m in height, 2. 2 m in width and 10. 5 m in length) , themaximum speed of more than 15 m/s, the low turbulence level, the low background noise of the wholefacility, together with the new noise measurement system. So large scale models can be tested withonly minor wall effects and at high Renolds numbers, and the pretentious acoustical measurements canbe performed. This paper describes the features of the new channel and the first test resultsobtained during extensive calibration and validation.展开更多
