After more than half a century of study on the aeroacoustics theory and the aircraft/engine noise control technology, further reduction of the aircraft noise encounters technical bottlenecks. Turbulence broadband noise has become a difficulty and the focus of the current aerodynamic noise control due to the complexity of its physical mechanism, the unavoidability during the flow process, and the universality in the airplane/engine flow field. In order to achieve the dream of ultra-quiet flight in the future, "learning from nature" which is the core of the noise control using bionic methods, has received unprecedented attention and been investigated extensively. Learning from nature can help to provide new aerodynamic noise control ideas and becomes a new vibrant aerodynamic noise control field. This paper addresses the aircraft/engine turbulence broadband noise control. Firstly, the history of the aerodynamic noise control with bionic methods is reviewed. Then a detailed introduction is presented for the current research situation of airfoil/blade trailing edge and leading edge noise reduction with bionic technologies. Finally, the main problems and future development directions of aerodynamic noise control with bionic methods are analyzed.
