Laser propulsion principle of laser propulsion

Laser propulsion is a new concept propulsion technology that uses long-distance high-energy laser to heat the gas working medium, causing the thermal expansion of the gas to generate thrust and propel the aircraft forward. It has the advantages of high specific impulse, large payload ratio, and low launch cost. , can be widely used in fields such as micro-satellite low-Earth orbit launch, earth orbit debris clearance, micro-satellite attitude and orbit control. When applied to satellite low-Earth orbit launches, the launch cost can be reduced to a few hundred dollars per kilogram, which is far lower than the current launch cost of tens of thousands of dollars per kilogram for chemical rockets. Therefore, it has attracted widespread attention from various countries.

According to reports, the laboratory currently has a scientific and technological innovation team composed of academicians of the Chinese Academy of Sciences, leading scientific and technological talents, and young and middle-aged academic experts. It mainly conducts basic research on laser propulsion application, plasma flow control and propulsion technology, and propulsion technology. Research on flow field testing and diagnostic technology. The establishment of the laboratory will effectively promote the basic theoretical research, cutting-edge technological innovation and scientific research results promotion of new technologies for my country's aerospace flight, and provide an important guarantee for the innovative development of new technologies for my country's aerospace flight.
