The Key Laboratory of High Temperatuer Gas Dynamics (LHD),Chinese Academy of Sciences(CAS),is devoted to research in the field of high temperature gas dynamics with the main background in hypersonic technologies. LHD was founded on the basis of the institute’s earlier gas dynamics division established by Professor Hsue-Shen Tsien and Proessor Yung-Huai Kuo in the late 1950s.Now under the leadership of Academician Hong-Ru Yu and guided by the vision of engineering science, LHD has developed into an open research base dedicated to innovative theoretical research, wind tunnel experiments and numerical simulations on high temperature gas dynamics. In the present. Professor Zonglin Jiang is the director of the laboratory and Professor Erjie Cui is the chairman of the academic committee.

 Research Vision

According to the scientific visions advocated by Professor Hsue-Shen Tsien. The laboratory targets at key strategic demands of aerospace and other closely related national economy fields. To build up a research and education base with sustainable innovation abilities and international-level research capabilities in the field of high temperature gas dynamics. The fundamentals of gas dynamics under hypersonic conditions are investigated to promote and support out national research in hypersonics by developing new methods new concepts and new techniques.

Researches on four fundamental topics in high temperature gas dynamics are carried out in the key laboratory of high-temperature gas dynamics.
