[0002] Because infrared radiation characteristic testing of military aero-engines requires dedicated testing sites and corresponding experimental testing technologies, the aero-engine test stand needs to be moved to a dedicated testing site. However, traditional aero-engine test stands are bulky, have complex equipment piping, are difficult to disassemble and move, and rely on external power supply. When the external power supply is insufficient, testing cannot be carried out, and infrared characteristic testing of military aero-engines cannot be conducted in the field. Therefore, there is an urgent need for a mobile ground test integrated support equipment that integrates fuel supply, lubricating oil supply, hydraulic oil supply, three-phase AC power supply, and high-pressure gas source.

Gas boosting system 2 is connected to fuel system 1, hydraulic system 3 and lubricating oil system 4 respectively. Fuel system 1 is connected to the engine under test and the starter under test respectively, and is used to supply oil to the engine under test and the starter under test. Lubricating oil system 4 is connected to the engine under test and the starter under test respectively, and is used for opening and sealing the engine under test and the starter under test.

[0049] Example 2

[0050] like Figure 3As shown, preferably, the fuel system 1 comprises a fuel tank 11, a first manual valve 12, a first explosion-proof solenoid valve 13, a first pressure sensor 14, a coarse filter 15, an oil-gas separator 16, a fuel pump 17, a fine filter 18, a precision filter 19, a first electronic pressure regulating valve 110, a flow meter 111, a first temperature sensor 112, and a second explosion-proof solenoid valve 113. The gas input end of the fuel tank 11 is connected to the gas booster system 2, and the liquid output end of the fuel tank 11 is sequentially connected via pipes to the first manual valve 12, the first explosion-proof solenoid valve 13, the first pressure sensor 14, the coarse filter 15, the first pressure sensor 14, the oil-gas separator 16, the fuel pump 17, the first pressure sensor 14, the fine filter 18, the first pressure sensor 14, the precision filter 19, the first pressure sensor 14, the first electronic pressure regulating valve 110, the flow meter 111, and the first pressure sensor 14. After the first temperature sensor 112, the system is divided into three paths. The oil pump 17 is connected in parallel with the second explosion-proof solenoid valve 113. The upper path connects to the engine under test via the first explosion-proof solenoid valve 13, the first pressure sensor 14, the flow meter 111, and the first manual valve 12, supplying oil to the engine under test. The middle path connects to the starter motor under test via the first explosion-proof solenoid valve 13, the first pressure sensor 14, the flow meter 111, and the first manual valve 12, supplying oil to the starter motor under test. The lower path connects to the fuel return port of the fuel tank 11 via the first explosion-proof solenoid valve 13, the oil pump 17, the first pressure sensor 14, the precision filter 19, the first pressure sensor 14, and the first manual valve 12. The first explosion-proof solenoid valve 13, the oil pump 17, the first electronic pressure regulating valve 110, the first pressure sensor 14, the flow meter 111, the first temperature sensor 112, and the second explosion-proof solenoid valve 113 are electrically connected to the control system 7.

[0051] The first manual valve 12, the first explosion-proof solenoid valve 13, the first pressure sensor 14, the oil pump 17, the precision filter 19, and the flow meter 111 are two or more.

[0052] The fuel tank 11 contains fuel oil.

[0053] Preferably, the coarse filter 15 has an accuracy of 20-40 μm, the fine filter 18 has an accuracy of 12-16 μm, and the precision filter 19 has an accuracy of 5-7 μm.

[0054] like Figure 4As shown, preferably, the oil tank 11 consists of an oil supply port 1101, an oil filling port 1102, an oil return port 1103, a pressure port 1104, a second oil level gauge 1105, a second safety valve 1106, an oil level indicator 1107, an oil drain port 1108, a drain outlet 1109, and an oil tank base 1110. The oil supply port 1101, oil filling port 1102, oil return port 1103, pressure port 1104, second oil level gauge 1105, and second safety valve 1106 are all located on the top of the oil tank 11. The oil level indicator... 1107 is located on the side of the fuel tank 11, the drain port 1108 and the filler port 1109 are located at the bottom of the side of the fuel tank 11, the fuel tank seat 1110 is located at the bottom of the fuel tank 11, the fuel tank 11 is filled by gravity through the filler port 1102, the fuel supply port 1101 is connected to the engine under test and the starter under test respectively to supply fuel to the engine under test and the starter under test, the pressurization port 1104 is connected to the gas pressurization system 2 to pressurize and release the fuel in the fuel tank 11, and the second fuel level gauge 1105 is electrically connected to the control system 7.

[0055] The fuel tank 11 is filled by gravity through the filler port 1102, and fuel is supplied to the engine and starter through the fuel supply port 1101. The gas pressurization system 2 pressurizes and releases the fuel in the fuel tank 11 through the pressurization port 1104. The second safety valve 1106 is set with a safety pressure limit value. When the pressure in the fuel tank 11 exceeds the limit value, the second safety valve 1106 automatically releases pressure to prevent the fuel tank 11 from being overpressurized. The fuel level indicator 1107 is used to display the amount of fuel in the fuel tank 11. The second fuel level gauge 1105 is used to remotely measure the amount of fuel remaining in the fuel tank. The drain port 1108 is used to drain the fuel in the fuel tank. The vent port 1109 is used to drain the sediment and impurities in the fuel tank.

[0056] The fuel system 1 can supply fuel using both pressure and pump methods to ensure reliable fuel supply. After the fuel truck adds fuel to the fuel tank 11, the fuel filler port 1102 of the fuel tank 11 is closed. The gas pressurization system 2 is used to pressurize the fuel in the fuel tank 11. When the required pressure is reached, the pressurization stops, and fuel supply can begin. When the pressure is lower than the required pressure, the gas pressurization system 2 will automatically pressurize the fuel tank 11 to ensure stable fuel supply pressure. After the fuel enters the fuel supply pipe from the fuel supply port 1101 of the fuel tank 11, it passes through the first manual valve 12, the first explosion-proof solenoid valve 13, the first pressure sensor 14, the 20-40μm coarse filter 15, the first pressure sensor 14, and the oil-gas separator 16 before entering the fuel pump 17 for fuel pump supply. If the fuel pump 17 malfunctions, the first explosion-proof solenoid valve 13 and the second explosion-proof solenoid valve 113 are opened to supply fuel by pressure. After fuel pump 17, the fuel passes through first pressure sensor 14, 12-16μm fine filter 18, first pressure sensor 14, 5-7μm precision filter 19, and first pressure sensor 14 before entering first electronic pressure regulating valve 110. After adjusting the fuel supply pressure to the specified pressure, it passes through flow meter 111, first explosion-proof solenoid valve 13, first pressure sensor 14, and first temperature sensor 112, then splits into three paths: the upper path is the fuel supply line of the engine under test, passing through first explosion-proof solenoid valve 13, first pressure sensor 14, and first temperature sensor 112. The oil supply line is connected to the test engine via the device 14, flow meter 111, and first manual valve 12; the middle line is the oil supply line for the test starter, which supplies oil to the test starter via the first explosion-proof solenoid valve 13, first pressure sensor 14, flow meter 111, and first manual valve 12; the lower line is the return line, which returns to the oil tank 11 via the first explosion-proof solenoid valve 13, oil pump 17, first pressure sensor 14, 5-7μm precision filter 19, first pressure sensor 14, first manual valve 12, and return port 1103.

[0057] This system employs a three-stage filtration system: a 20-40μm coarse filter 15, a 12-16μm fine filter 18, and a 5-7μm precision filter 19, to filter impurities in the fuel and provide the engine and starter with fuel that meets the requirements. A first explosion-proof solenoid valve 13 controls the timing of fuel injection. A first pressure sensor 14 measures the fuel injection pressure; the first pressure sensors 14 at both ends of the filter can measure the pressure loss of the fuel after passing through the filter, determine the filter's clogging status, and thus determine when to clean the filter. An oil-gas separator 16 separates air from the fuel to ensure stable engine operation. A first electronic pressure regulating valve 110 is an electronically controlled pressure regulating device used to adjust the fuel injection pressure to meet test run requirements. A first temperature sensor 112 monitors the fuel injection temperature.

The first safety valve 23 and the manual master valve 24 are installed on the connecting pipeline between the high-pressure gas tank 22 and the air filter 25. The connecting pipeline after the air filter 25 is divided into three paths. The air filter 25 is connected to the fuel system 1, the hydraulic system 3, and the lubricating oil system 4 after passing through the second electronic pressure regulating valve 26, the third explosion-proof solenoid valve 27, the second pressure sensor 28, the second manual valve 29, and the vent valve 210, respectively. The air compressor 21, the second electronic pressure regulating valve 26, the third explosion-proof solenoid valve 27, and the second pressure sensor 28 are electrically connected to the control system 7.

[0060] The gas booster system 2 is used to provide high-pressure air to each oil tank or reservoir of the fuel system 1, hydraulic system 3 and lubricating oil system 4, ensuring that each system can provide the engine with fuel, lubricating oil and hydraulic oil at a stable pressure.

[0061] When the air compressor 21 starts working, it first fills the high-pressure air tank 22 with air. Then, the compressed air is divided into three paths after passing through the manual master valve 24 and the air filter 25. The gas pressure is adjusted to a suitable pressure by the second electronic pressure regulating valve 26. Then, the high-pressure air is provided to each oil tank or oil container of the fuel system 1, hydraulic system 3 and lubricating oil system 4 by the third explosion-proof solenoid valve 27 and the second manual valve 29.

[0062] The first safety valve 23 is set with a safety pressure limit value. When the pressure in the pipe exceeds this limit value, the first safety valve 23 will automatically release pressure. The second electronic pressure regulating valve 26 is an electronic device for controlling the upper limit pressure of the gas, used to ensure that the gas supply pressure meets the requirements. The second pressure sensor 28 is used to measure the pressure of the boosted air and provide data for the pressure regulation of the second electronic pressure regulating valve 26. The vent valve 210 is used to vent the various oil tanks or reservoirs of the fuel system 1, hydraulic system 3 and lubricating oil system 4 after the aircraft engine test is completed.
