The&32;general&32;contract&32;project&32;of&32;the&32;environment-simulation&32;wind&32;tunnel&32;and&32;the&32;wind&32;tunnel&32;of&32;aerodynamics&32;and&32;acoustics&32;of&32;China&32;Automotive&32;Engineering&32;Research&32;Institute&32;Co,&32;Ltd.
This is a full-size environment-simulation automotive wind tunnel, and also a full-size automotive wind tunnel of aerodynamics and acoustics. For the environment-simulation automotive wind tunnel, the maximum wind speed may reach up to 200 km per hour, with a temperature from -40℃ to 60 ℃ , and relative humidity from 5% to 95%; and for the automotive wind tunnel of aerodynamics and acoustics, the maximum wind speed may reach up to 250km, with a background noise of 58 Db (A) @ 140 km per hour.
