AI Technical Summary

Problems solved by technology

At present, there are few researches on plasma high-speed flow control experimental technology in my country. This is mainly because tens of thousands of volts of high voltage need to be applied during plasma discharge, and plasma discharge experiments are carried out in all-steel high-speed wind tunnels. How to prevent high voltage from causing damage to personnel and experimental instruments, there is no good solution at present
