Sky Flight Science and Technology Center
The Sky Flight Science and Technology Center is an academy-level unincorporated scientific research unit. Relying on the construction of the Institute of Mechanics, it expands its connotation and extension on the basis of the original hypersonic science and technology center. It was established in April 2019 with the approval of the Chinese Academy of Sciences. The main purpose of the establishment is to realize the overall planning and optimization of the strength of the whole hospital in the field of space flight science and technology through the top-level design; to realize the major integration of resources and achievements by building a platform; and to realize the overall docking between our hospital and the outside through a unified interface.
