Problems solved by technology
[0002] In the current aircraft fuel tank delivery system, the fuel tank of each engine is usually composed of a fuel collection tank and multiple fuel delivery tanks arranged side by side on the side of the fuel collection tank; when supplying fuel, the fuel is transferred from the outer fuel delivery tank to the inner fuel delivery tank through the fuel delivery pump And finally transferred to the fuel collection tank, the fuel collection tank then delivers the fuel to the engine through the fuel supply pump, which often has problems such as complex structure and high weight cost, which affects the stability of fuel delivery and the safety performance of the aircraft

Embodiment Construction
[0017] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated.
[0018] like figure 1 As shown, the oil supply and delivery system in the fuel tank provided by the present invention is used for supplying oil to aircraft engines (which may be one or more). The oil supply and delivery system in the current oil tank can include the oil collection tank 1 and be arranged side by side at the oil collection tank 1 side (referring to figure 1 A plurality of fuel delivery tanks 2 in the arrangement shown in ). The oil supply and delivery system in the fuel tank of the present invention may also include an oil supply pump 11, a jet pump 21, and an oil supply cut-off valve 31 with an electric mechanism.
[0019] The oil supply pump 11 can b...

The invention relates to the field of aircraft fuel system design, and in particular to an oil supplying and conveying system in an oil tank. In the oil supplying and conveying system in the oil tank, the oil outlet port of an oil supply pump in an oil sump tank is divided into a first oil outlet pipeline and a second oil outlet pipeline. In addition, movable flow inlets of all jet pumps are connected to the second oil outlet pipeline, and therefore the oil supply pump can serve as an ejecting movable flow source of the jet pumps; and the jet pumps are controlled to pump fuel in an oil conveying tank into the oil sump tank, and then the fuel is then conveyed to an engine through the first oil outlet pipeline of the oil supply pump. The oil supplying and conveying system in the oil tank is simple in structure and high in stability, and the overall mass of the oil tank can be reduced.
