The application provides a kind of override architecture of cut-off valve and its installation method and operation method, even if the control solenoid fails and is invalid, it can make the gas path normally on-off, the fuel path normally on-off, so as to normally supply oil to fuel tank or stop. The override architecture of cut-off valve comprises: a manual override device, which is arranged away from the control solenoid and the cut-off valve in the original machine pressure pipeline; a transmission assembly, the input end of which is connected to the manual override device, and the output end of which is connected to the original machine pressure pipeline, which can transmit the movement of the manual override device to the original machine pressure pipeline; an elastic sealing assembly in the pipe, which is connected to the output end of the transmission assembly, and blocks the gas inlet of the original machine pressure pipeline to form a normally closed sealing structure, when the manual override device works, the gas path is conducted, and the fuel path is conducted, when the manual override device stops working, the gas path is disconnected, and the fuel path is disconnected.

The application discloses a fuel supply system of a small large-maneuvering flying-wing type unmanned aerial vehicle and a working method thereof, and relates to the technical field of unmanned aerial vehicles. The system comprises an airborne fuel system (23) and a ground fueling system (26), wherein the ground fueling system (26) is used for realizing fueling and oil pumping of the airborne fuel system (23); the airborne fuel system (23) comprises a hard fuel tank (4), a single-layer vacuum soft fuel tank and a double-layer pressurized vacuum soft fuel tank, the single-layer vacuum soft fuel tank and the double-layer pressurized vacuum soft fuel tank are communicated with the hard fuel tank (4), and the hard fuel tank is communicated with an engine (18) of the unmanned aerial vehicle. The application adopts a combined and optimized layout of multiple soft fuel tanks and a hard fuel tank, improves total fuel loading capacity, has the advantages that the vacuum soft fuel tank has less residual oil and the hard fuel tank can monitor residual oil quantity, and adopts sequential fuel supply controlled by air pressure in a fuel supply process, so that the structure is simple and reliable, and the center of gravity is less deviated.

The present disclosure relates to a method for servicing an aircraft (300) by a ground service unit (200). The method comprises reading (510) a wireless parameter signal from a transponder (325) at the aircraft (300), decoding (520) the wireless parameter signal to derive at least one aircraft parameter of a water supply system (310) and / or a waste system (312) of the aircraft (300), moving (530) a servicing equipment interface (222) to a service panel (320) of the aircraft (300), connecting (540) the servicing equipment interface (222) to a coupling (321, 327) at the service panel (320), servicing (550) the aircraft (300) via the servicing equipment interface (222) corresponding to the at least one aircraft parameter, and writing (560) a service parameter into the transponder (325) at the aircraft (300).

The utility model discloses a novel winding protection device for a refueling rubber tube of a tank type aircraft refueling truck, which comprises a first mounting seat, a refueling rubber tube and a second mounting seat, and a group of screw holes are respectively formed in the front parts and the rear parts of the corresponding ends of the first mounting seat and the second mounting seat; supporting devices are fixedly mounted at the corresponding ends of the first mounting base and the second mounting base correspondingly, a limiting device is slidably mounted at the corresponding ends of the first mounting base and the second mounting base jointly, and the refueling rubber pipe is mounted at the front end of the limiting device in a penetrating mode. According to the novel winding protection device for the refueling rubber pipe of the tank type aircraft refueling vehicle, when the refueling rubber pipe is recycled, the refueling rubber pipe can be limited through the two second limiting rollers and the two first limiting rollers, shaking of the refueling rubber pipe is avoided, the limiting rollers can rotate along with winding of the refueling rubber pipe, and therefore the refueling rubber pipe is prevented from being wound. And the abrasion between the oiling rubber pipe and the limiting roller is reduced.

An aircraft fueling adapter incorporating an aircraft fueling adapter flow meter is disclosed for improving accuracy of fueling protocols by providing an additional independent flow data point in mass units and / or volume units in the fueling process that can be compared against existing fuel flow readings.
