China News Service, Harbin, June 17 (Reporter Yifu Shi) Harbin Institute of Technology announced on the 17th that after the Tianhe core module was launched into orbit, the first rendezvous and docking mission with the manned spacecraft was supported by many technologies. The docking and launch.
Space rendezvous and docking is an indispensable operation of modern spacecraft during long-term orbit operation, and is one of the three basic technologies for manned space activities.
Space docking mechanism is a system that realizes the on-orbit mechanical connection between spacecraft, and establishes a combination of spacecraft joint flight and safe separation.
Behind this, there is always technical support from the team of Professor Wang Langping, School of Materials, Harbin Institute of Technology.
Professor Wang Langping’s team used ion implantation and deposition technology to achieve the preparation of the hardness and composition double gradient transition composite surface strengthening layer, and achieved high wear resistance, self-lubrication and cold welding resistance in the space environment, thus conquering the core of the space docking mechanism The surface strengthening problem of parts, and the development of ion implantation and deposition industrial equipment, which provides equipment conditions for the surface strengthening of more than 50 core parts on the space docking mechanism, realizes the independent control of key technologies, and guarantees the Shenzhou-8 to Shenzhou Reliable docking between the 12th spacecraft and the target aircraft.
The series of ground test equipment for space docking mechanism developed by Professor Zhao Jie’s team from the School of Mechanical and Electrical Engineering of Harbin Institute of Technology has played an irreplaceable role in the process of docking mechanism prototype development, finalization assessment, and pre-launch verification. The mission of space docking is foolproof.
The core cabin space manipulator is the key equipment of the Chinese space station. It will undertake core tasks such as astronaut out of the cabin, space station construction, use and maintenance in the future, and provide key equipment guarantees for China's long-term space residence and on-orbit services.
A series of multi-dimensional, high-fidelity zero-gravity assembly and test equipment developed by Professor Qi Naiming's team from the School of Astronautics of Harbin Institute of Technology has successfully completed the overall assembly of the core module manipulator and the ground tests at various stages.
In addition, the team of Professor Huang Yudong from the School of Chemical Engineering and Chemistry of Harbin Institute of Technology has completed the development of key technologies for the nozzle diffusion section of the escape system of the Shenzhou series spacecraft No. 12.
Aiming at the uneven bonding of the fiber and resin interface in the composite material of the nozzle diffusion section, the team invented a new process and new equipment for interfacial impregnation and strengthening during the composite process of phenolic resin and reinforcement, forming a general technology for solid rocket motor nozzle molding .
Using this technology can reduce the dispersion coefficient of the interlayer shear strength of the composite material, greatly improve the quality reliability and safety of the engine nozzle, and lay a solid foundation for ensuring the safety of the astronauts. (Finish)
