With the demand for higher speeds and longer endurance of future near-space hypersonic vehicles,multiscale coupling thermal effects are becoming increasingly important,which can significantly affect hypersonic flight safety.Given the thermal phenomena involved in high-temperature surfaces and structures and cabin instruments/components of hypersonic vehicles,research progress on the prediction methods of multiscale coupling thermal effects was reviewed in this paper.Considering the design requirements of refinement and low redundancy of future vehicles,focused follow-up research was further proposed.The coupling thermal effects need to be extended from the presentative"macroscopic variables"to the intrinsic"hidden variables"affecting macroscopic performance.Cross-scale correlation must realize the coordination of"downscaling"and"upscaling".Meanwhile,basic mathematical models and adaptive methods must be developed to weaken or eliminate artificial boundaries and human experience.This work would provide a reference for the precise prediction and effective protection of aircraft thermal behaviors.
