Laser weapon is thought to be a sign of next generation fighter plane. The heat produced by laser during working cycle has reached a level as high as 106W

while electric-photovoltaic conversion of laser weapon was only 10%-20%. A bulky cooling equipment will be needed to clear the heat off

which can’t meet the strict standard of bulk and weight on plane. This topic discussed several projects to solve the problem

such as phase change energy storage technology

loop heat pipe technology and enhanced heat transfer technology. It is concluded that the application of phase change storage technology can effectively deal with the impact of high power laser heat flux on airborne thermal management system

and it is an inevitable trend of the development of aircraft thermal management system.
