The invention relates to the ventilation tank residual fuel drainage technology of aircraft fuel systems, in particular to a ventilation tank residual fuel drainage system of a reversed wing fuel system of a large aircraft. The system aims to solve the problems that the fuel drainage efficiency of the residual fuel drainage system is low, and the residual fuel drainage system is not convenient to use. In the residual fuel drainage system, a scavenge fuel ejector pump is arranged in the ventilation tank, an electric fuel feed pump in a main fuel tank servers as a dynamic flow source of the scavenge fuel ejector pump, residual fuel in the ventilation tank is drained into the main fuel tank, and in addition, residual fuel in the ventilation tank can be further drained clean through a sediment releasing valve on the bottom of the ventilation tank. The structure is simple, the fuel drainage efficiency is high, operation is convenient, and fuel can be prevented from being sprayed to the bodies of ground maintenance personnel and polluting the ambient environment.
