Description

Technical Field

[0001] The present application relates to the technical field of aircraft fuel recovery, and in particular to an aircraft fuel recycling method and system. Background Art

[0002] Aircraft maintenance requires regular drainage of water and sediment from the bottom of the wing fuel tanks. Fuel sediment drainage is a required subject in aircraft maintenance skills training. During this practical skills training, trainees are required to drain fuel sediment from the drain valve at the bottom of the tank. Each person drains between 100 and 500 milliliters of fuel per training session, so the training program generates a large amount of excess fuel. Conventional methods for handling this waste oil include collecting it as waste and regularly sending it to a designated company for waste liquid treatment. Alternatively, trainees can pour the fuel back into the aircraft's wing tanks through gravity refueling ports. However, if the aircraft's excess fuel is treated as waste liquid, the cost is high, and the aircraft also consumes more fuel. If the fuel is returned to the wing tanks, frequent wingtip access is required, and without adequate protective measures, there is a risk of falling from height. Furthermore, if the fuel is returned to the tanks without treatment, contamination is unavoidable. Summary of the Invention

[0078] On the other hand, an embodiment of the present invention further provides an aircraft fuel recycling method, which is implemented by the aircraft fuel recycling system as described above. The aircraft fuel recycling method includes the following steps:

[0079] S100, realizing aircraft fuel recycling through oil collecting port 1, oil storage tank 2, control box 3, oil pump 4, oil filter 5, oil pipe 6, and sensor 7.

[0082] S300: Based on the oil draining and sedimentation operation information, the docking adapter 9 is installed on the oil collection port 1, the docking adapter 9 is docked with the oil drain valve 81, the oil drain valve 81 is opened to collect oil, and the collected oil information is obtained through the sensor 7; the collected oil information includes oil level information, filtration information, and light warning information;

[0083] S400: Drain the oil from the oil storage tank 2 or replace the oil filter 5 according to the oil collection information.

[0084] As an optional implementation, refer to Figure 2 The embodiment of the present invention forms a fuel circulation recovery system through the process of "oil discharge, collection, storage, filtration, and oil return", achieving "zero loss and zero pollution" of fuel in the actual operation of fuel sedimentation discharge.

[0085] Fuel draining phase: Trainees perform fuel draining and settling operations according to the aircraft maintenance manual (including fuel draining and settling operation information), and the fuel is discharged from the fuel drain valve 81 at the bottom of the aircraft fuel tank.

[0086] Collection stage: Install the funnel 91 at the oil collection port 1 and place it below the oil drain valve 81, and drain the fuel into the oil collection port 1 to collect the oil.

[0087] During the storage phase, the pipeline connecting the oil collecting port 1 is inserted into the fuel storage tank 2, where the fuel discharged from the aircraft is stored. A low oil level sensor 712 and a high oil level sensor 711 are respectively installed at the bottom and top of the fuel storage tank 2 to detect the oil level and control the operation of the fuel pump 4.

[0088] Filtration: Before being pumped back into the aircraft's fuel tank, the oil passes through a high-efficiency oil filter to ensure fuel purity. A differential pressure sensor 72 is installed between the inlet and outlet of the oil filter to monitor fuel purity. When the differential pressure exceeds a set value, a prompt is issued to replace the oil filter 5.

[0089] Oil return stage: When the oil reaches the high oil level sensor 711, the oil pump 4 automatically starts and pumps the oil back to the aircraft fuel tank through the oil filter 5. The oil pump 4 can also be manually controlled to pump oil; when the oil returns to the low oil level sensor 712, the oil pump 4 stops working.

[0090] As an optional implementation, refer to Figure 3 The aircraft fuel recycling and recovery system of the present invention includes a fuel recycling and recovery loading vehicle, which is used to store excess fuel from trainees' fuel release. Once a certain amount of excess fuel is collected, it is recycled into the aircraft's wing tanks via the aircraft's gravity refueling ports. The loading vehicle functions as a fuel storage, fuel filtration, and fuel circulation system. The fuel storage system utilizes a closed structure, yet is easily disassembled for internal cleaning.

[0092] The control principle of the embodiment of the present invention is as follows: When the oil in the oil storage tank 2 reaches the high oil level sensor 711 located at the top, the controller in the control box 3 energizes the oil pump 4, and the oil is pumped back into the aircraft fuel tank. The valve 42 of the oil pump 4 can also be manually controlled to start. When the oil returns to the low oil level sensor 712 located at the bottom of the oil storage tank 2, the controller de-energizes the oil pump 4. The differential pressure sensor 72 is used to detect the pressure difference between the inlet and outlet of the oil filter 5 to monitor the flow resistance of the oil filter 5 and determine whether the oil filter 5 is dirty or clogged. When the pressure difference exceeds the set value, the controller will replace the oil filter 5 through the light and voice prompt module to achieve fuel purification.

[0093] This invention enables fuel recycling during aircraft fuel sedimentation training, avoiding excess fuel and thus saving the cost of treating it as industrial waste. Furthermore, a pump automatically returns the fuel to the aircraft's fuel tank, eliminating the safety risks associated with trainees pouring fuel back into the tank during high-altitude operations. Therefore, this invention has significant economic and environmental value, and improves production safety.

In addition, the memory may include a high-speed random access memory and may also include a non-transient memory, such as at least one disk storage device, a flash memory device, or other non-transient solid-state storage device.

Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.
