We are honored to welcome Mr. Richard Liu (刘强东), the founder of JINGDONG, to our Aerodynamics and Acoustics Facility. Prof. ZHANG Xin and Prof. ZHOU Peng presented a series of assessments to illustrate how drones can function effectively while reducing their acoustic impact. For example, LAE noise assessment, route planning, wind safety, low noise design, drone testing in an anechoic chamber, and an outdoor drone noise assessment system.
