The State Key Laboratory of High-Temperatue Gas Dynamics (LHD), Chinese Academy of Sciences (CAS), is devoted to the research of high-temperature gas dynamics in the context of hypersonic technologies. LHD was founded based on the Department of Gas Dynamics established by Professor Qian Xuesen and Professor Guo Yonghuai in the late 1950s. Currently, led by Academician Yu Hongru 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.
Research Vision
According to the scientific visions advocated by Professor Qian Xuesen, the laboratory intends to build up a research and education base with sustainable innovation abilities and international research capabilities in the field of high-temperature gas dynamics by focusing on the key strategic demands of aerospace and other fields closely related to the national economy. The fundamentals of gas dynamics under hypersonic conditions are studied to promote and support national research in hypersonics by developing new methods, new concepts and new techniques.
LHD researches four fundamental topics in high-temperature gas dynamics.
