Shenzhou 16 went to heaven. The reporter learned from Nanjing University of Aeronautics and Astronautics that the teachers and students of China Southern Airlines have been helping and contributing to the wisdom and strength of China Southern Airlines during the dream-seeking journey of Shenzhou series spacecraft.
Underwater manipulator helps to complete the extravehicular task. Entrusted by the Astronaut Center and Shanghai Aerospace Systems Engineering Research Institute, the research team of China Southern Airlines participated in the development of "underwater manipulator and its intelligent control system". The system realistically simulates the conditions of manipulator transfer and fixed-point operation in the extravehicular activities of the space station, which is an important guarantee for engineering experiment verification and astronaut training in extravehicular activities.
Under the guidance of the overall unit of the Astronaut Center, the joint research group of Shanghai Aerospace Systems Engineering Research Institute innovatively developed the first domestic10m underwater manipulator with large workspace, high reliability and high safety through technical approach simulation verification, overall scheme design, engineering implementation, debugging and trial operation.
Among them, the research team carried out academic research and engineering development of underwater manipulator control system, man-machine interaction system and power supply and distribution support system for the training task of neutral floating box astronauts in simulated weightlessness environment.
As the core command center of the whole system, the contents developed by the research group have broken through the underwater path planning technology based on multi-sensor fusion and optimization algorithm, the man-machine interaction control technology of underwater manipulator, the detection and prediction technology of virtual double-body large-scale space collision, and the underwater safety monitoring technology, effectively ensuring the reliable and efficient operation of the whole system, which is a breakthrough in the application of underwater robot control technology in manned space simulated weightlessness training.
Various technologies are used to protect the flight of Shenzhou. In addition to helping the successful completion of the extravehicular mission, China Southern Airlines also contributed to ensuring the flight of Shenzhou. The research team of China Southern Airlines undertook the research on welding deformation control of a new generation of manned rocket tanks, which broke through the precise shape control technology in the welding process of aerospace aluminum alloy large-scale complex structures and helped the development of a new generation of manned launch vehicles.
The research team of China Southern Airlines has been devoted to the research of parachute aerodynamic deceleration technology for a long time, which has provided strong technical support for the optimal design of parachute system in shenzhou spaceship and important guidance for the evaluation method of large parachute optimization test in shenzhou spaceship.
In the early days of shenzhou spaceship launch, the scientific research team of China Southern Airlines spent several years tackling key problems and designed a "shock absorption jacket" to allow the rocket to be safely transported to the launch site. Precision laser welding and high-efficiency additive manufacturing technology of spacecraft heat-resistant load-bearing structure have been developed and applied to the research and development and production of cargo spacecraft and manned spacecraft in China's manned space mission.
Paying attention to people who care about the environment and ensuring the "Tiangong" to survey the sky, the research team of China Southern Airlines also carried out research on intelligent grid-connected control and protection technology of spacecraft for manned space missions such as the space station. In the process of space flight, astronauts face special environments such as weightlessness, sub-magnetic field, noise and radiation, and the health status of astronauts has a great influence on the completion of space missions. The research team of China Southern Airlines focuses on the special space environment and pays attention to the brain function and visual health of astronauts.
The whole machine characteristic test system of space station indexing mechanism developed by the scientific research team of China Southern Airlines has solved the problem of mechanical load simulation and test of indexing mechanism products in the ground environment, and played an important role in the design and verification of the working boundary of indexing mechanism products.
In order to reduce the vibration and impact during spacecraft docking, the research team of China Southern Airlines developed a set of high and low temperature test system for electromagnetic dampers to test whether the damping characteristics of electromagnetic dampers meet the design requirements in space environment, which has been applied to many Shenzhou series spacecraft missions.
In addition, the research team of China Southern Airlines also participated in a number of scientific research projects, such as dynamic control of on-orbit self-assembly of space structure, fatigue evaluation and test verification of space station extension mechanism, design of flexible solar wing of space station, high-power power power supply system of space station, in-situ multi-robot collaborative assembly technology of complex structure of core cabin, space-grade lightweight nano-vacuum insulation panel, space on-orbit robot, new space weak impact docking mechanism and its compliance control technology.
