| Abstract:Hypersonic aircraft represents a crucial focus in equipment development, owing to their exceptional high-speed penetra?
tion and swift strike capabilities. However, stringent requirements for thermal management and power supply are imposed by hypersonic
flight conditions. A comprehensive review of technologies concerning thermal protection, fuel thermal management and inlet air precooling
is conducted. Thermal management significantly impacts the performance and function of hypersonic engines, but its current technical
maturity level in this field is relatively low. The integration of airframe and engine is identified as one of the important approaches for
addressing these challenges. A literature review was conducted to compare the generation and utilization technologies of power supply with
traditional aircraft. Key technologies of primary power supply methods in existing hypersonic engines are outlined, including the fuel vapor
turbine. The future developmental trends in power and thermal management are summarized, such as thermoelectric conversion, providing
a reference for the development of integrated power and thermal management technologies for hypersonic engines. |
