Embodiment Construction
[0036] 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.
[0037] Such as Figure 1 to Figure 3 As shown, the verification device of the present invention is mainly used for verification experiments on the aircraft zero-load overload fuel supply pressurization system.
[0038] In the aircraft zero-load overload fuel supply pressurization system aimed at by the present invention, the pressurized oil tank 9 is pressurized through a separately provided high-pressure gas cylinder 10 . Specifically, such as figure 2 As shown, the interior of the accumulator fuel tank 10 is divided into an air chamber 92 and a fuel chamber 93 by an elastic diaphragm 91 . Wherein, the air chamber 92 has a pressurization adapter pipe 94 communicati...

The invention relates to the technical field of airplane oil supply pressurization systems, in particular to an airplane zero and negative overload oil supply pressurization system verifying device and a usage method thereof, and the verification test requirements of an airplane zero and negative overload oil supply pressurization system can be met. The verifying device comprises an oil tank which is communicated with a fuel oil cavity in a pressure accumulation oil tank through an oil filling pipeline and an oil returning pipeline; the oil filling pipeline is provided with an electric switch and a flowmeter, the oil returning pipeline is provided with an electric switch, a flowmeter and a pressure sensor, and the electric switches, the flowmeters and the pressure sensor are all connected with an industrial personal computer. According to the verifying device and the usage method thereof, the airplane zero and negative overload oil supply pressurization system oil supply can be simulated; meanwhile, the needed data such as the flow and the pressure in oil supply can be acquired through devices such as the flowmeters and the pressure sensor, and therefore the verification test requirements of the airplane zero and negative overload oil supply pressurization system can be met.
Description
technical field [0001] The invention relates to the technical field of an aircraft fuel supply pressurization system, and relates to a verification device for an aircraft zero-load overload fuel supply pressurization system and a method for using the same. Background technique [0002] In the field of aircraft design, according to the needs of tasks and functions, it is necessary to design an aircraft zero-load overload fuel supply system to ensure that the fuel system can continuously and effectively supply fuel according to the flow and pressure requirements when the aircraft is in a zero-load overload state. Among them, the pressure accumulator fuel tank is one of the main devices to meet the zero-load and overload fuel supply of the aircraft, and the pressurized gas mainly comes from the engine bleed gas. However, in some cases, the engine bleed air gas may not be able to meet the pressurized gas requirements for fuel supply to the accumulator fuel tank, so that the fuel...
