Based on the flight test project of weightlessness test, this paper summarizes the refit and test of the weightlessness test aircraft fuel system. It focuses on the possible problems of the aircraft fuel system under the conditions of weightlessness, the selection of weightlessness test aircraft, the modification of the fuel system, the flight test method, the flight test And the result. After comparative analysis, the results show that the fuel system modification and test method adopted in the flight test of weightlessness test aircraft is reasonable and has certain engineering practical value.
