Peiqing Liu received his D.Eng. from Tsinghua University in 1995, and is currently a Professor at the School of Aeronautic Science and Engineering, Beihang University. Since 1997, he has worked at the Institute of Fluid mechanics at Beijing University of Aeronautics and Astronautics. He has been engaged in aerodynamics, hydrodynamic experiments and numerical simulation for many years and has been involved in NSFC key projects, general projects, national defense pre-research and national defense foundation research on complex flows (vortex separation and control, high-speed laminar flow control technology, etc.). His main interests include modern aircraft vortex separation and control technology, high-speed, laminar flow control technology; efficient, lightweight propeller design and optimization technologies; and large aircraft aerodynamic characteristics, ground effect and ditching. He has published more than 200 papers in national and international journals and 8 books, and he holds 19 national invention patents.
