The Aerodynamics, Acoustics and Noise control Technology Centre (AANTC), led by Dr Zhang, Xin, conducts fundamental research in aerodynamics and aeroacoustics, with applications in aircraft, propulsion, and sports industry. The Centre develops and applies advanced numerical simulation methods, advanced anechoic wind tunnels, fluid-acoustic facilities, and acoustic chambers. It designs and operates its own purpose-built anechoic wind tunnels, fluid-acoustic tubes, meta-acoustic material test platforms, anechoic chambers and senor suites. The Center also develops and uses several software suites for aerodynamic simulation, noise prediction, and performance analysis. One of the Centre’s key research areas is the aerodynamics and acoustics of flying systems in low-altitude airspace. The Centre conducts world-leading research in aerodynamic and acoustic testing, flight safety, noise impact, low-noise design, sound transmission, and route planning in low-altitude airspace. It provides technological solutions for the industry. The Centre also conducts research and development in sports science and technology. It develops its own aerodynamic test platforms, sensors and performance analysis software for cycling, windsurfing and sailing, and works closely with national and international sports teams.
Unmanned air mobility (UAM) or drones can be widely applied to various scenarios such as photography, entertainment, security, logistics and delivery, civil engineering inspection, infrastructure maintenance. The high efficiency, high flexibility and low-cost properties make it promising transportation means for the modern smart cities. The development of the drone for the passengers and cargo in a city is a potential solution to reduce the traffic jam. However, the widening application of drones in populated cities can cause noise pollution. In AANTC, the drone noise properties are investigated using combined methodologies of numerical simulation, experimental analysis and theoretical analysis. The drone noise impact on the environment is evaluated, and the strategies to reduce the noise impact to are being explored for the purpose of low-noise, low-emission and high-efficiency drone applications. The target requires multi-disciplinary studies such as aerodynamics and aeroacoustics, operation research and intelligent transportations.
