Abstract
In order to suppress the overtemperature phenomenon of airborne cooling system under transient conditions and protect sensitive airborne equipment,variable architecture and control strate-gy are adopted to realize the rapid reconstruction of the architecture under transient temperature rise conditions and suppress the system overtemperature phenomenon.The transient over-temperature per-formance of the system before and after the suppression design was compared by calculation,a new experimental scheme was explored,and the real overtemperature suppression ability was tested and verified.The results show that the method of rapid architecture reconstruction can significantly re-strain the overtemperature phenomenon of airborne cooling system under transient conditions and protect sensitive airborne equipment.At the same time,a verification and test technology of overtem-perature suppression ability of airborne equipment is proposed.
