Hydrogen power is one of the important forms to promote the realization of the "double caibon" goal in aviation field. The manufacturing ,testing and qualification of hydrogen power will provide important support for the realization of the "double caibon" goal in aviation field. In this paper, the development background of hydrogen energy power at home and abroad is analyzed in combination with the "double caibon" goal in aviation field,and the forward planning of hydrogen energy power and the latest progress of the overall flight test of hydrogen energy power are systematically reviewed. The key technologies of hydrogen power flight test are analyzed in detail, and the technology of adapting to aeroengine flight platform is analyzed emphatically. It covers hydrogen storage and transportation, adaptation of hydrogen powered flight platforms, special measurement technologies, safety protection and control technologies, flight test supporting facilities, flight test verification and evaluation technologies, and airworthiness compliance studies. The aim is to provide reference for the research on hydrogen power demonstration, hydrogen power product evaluation, safe operation of hydrogen power, aviation technology innovation, low carbon and high quality development of aviation.
