[0002] The aircraft engine is the heart of the aircraft, and the engine ignition system is one of the important parts of the aircraft engine. It is an ignition source system for the main combustion chamber and the afterburner, which is composed of an ignition device, an ignition cable, and an ignition nozzle. After the ignition device converts the direct current or alternating current on the aircraft into high voltage electricity, it releases sparks through the ignition cable and nozzle and ensures that the sparks have enough energy to directly ignite the mixture of air and fuel in the engine combustion chamber. Understanding the basic working parameters of the ignition device can reliably control the entire ignition process.

[0003] At present, the matching ignition nozzle can only meet the inspection of ignition process parameters under the basic working specifications of the ignition device, and the acceptance and delivery of the ignition device also requires basic parameter inspections such as open circuit, high altitude, output voltage, and working capacity. Since each ignition nozzle has its fixed ignition voltage, it cannot meet the inspection of various basic parameters of the ignition device. Therefore, it is necessary to develop an ignition device performance test equipment to solve the problem. Summary of the invention

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0021] Example 1 like Figures 1 to 3 As shown, an ignition device performance test device includes a mounting platform 4; Two groups of test electrode assemblies are relatively arranged on the mounting platform 4, and the test electrode assemblies include a support rod 5 arranged on the mounting platform 4 and an electrode unit arranged on the support rod 5. The support rod 5 is arranged perpendicular to the mounting platform 4 in the vertical direction. The electrode unit includes a mounting rod 6 and a spherical electrode 8 arranged at one end of the mounting rod 6 and coaxial with the mounting rod 6. The mounting rod 6 is horizontally arranged on the support rod 5 and is slidably connected between the support rods 5, so that the mounting rod 6 can slide in the horizontal direction along its axis, and the mounting rods 6 of the two groups of test electrode assemblies can always be located on the same straight line. The spherical electrodes 8 in the two groups of test electrodes are located between the support rods 5 and are arranged at relative intervals; A drainage assembly is disposed on the mounting platform 4 , and the drainage assembly includes a drainage needle 13 that can extend between the two spherical electrodes 8 .

[0022] The present invention arranges two spherical electrodes 8 relatively to each other, and arranges the mounting rod 6 horizontally on the support rod 5 and is slidably connected with the support rod 5, so that the mounting rod 6 can slide in the horizontal direction along its axis, change the gap between the two electrodes, and arrange a drainage needle 13 in the gap to realize the test inspection of the output voltage and working capacity of different models of ignition devices.

[0023] In some embodiments, reference Figure 1 and Figure 2 A support 7 is provided between the mounting rod 6 and the spherical electrode 8. One end of the support 7 is used to support the spherical electrode 8, and the other end is fixed to the mounting rod 6. The support 7 makes the spherical electrode 8 more firmly installed, which can improve the accuracy of the test.

[0024] like Figure 2 and Figure 3 As shown, a first mounting hole 14 is provided on the support rod 5, and a second mounting hole 14 is provided on the mounting platform 4. The mounting rod 6 is cooperatively arranged in the first mounting hole 14, and the support rod 5 is cooperatively arranged in the second mounting hole 14. Further, the first mounting hole 14 and the second mounting hole 14 are waist-shaped holes. The waist-shaped first mounting hole 14 and the second mounting hole 14 can limit the rotation of the mounting rod 6 and the support rod 5 along their corresponding axes, thereby preventing the mounting rod 6 and the support rod 5 from rotating at their own angles due to misoperation when adjusting the mounting rod 6 and the support rod 5, so that the two spherical electrodes 8 cannot be on the same axis.

[0025] A fourth mounting hole 14 is provided on the support rod 5 along its longitudinal direction, and the fourth mounting hole 14 is communicated with the first mounting hole 14. A locking piece 10 for fixing the mounting rod 6 is provided in the fourth mounting hole 14. When the mounting rod 6 slides to a fixed position in the first mounting hole 14, the mounting rod 6 is fixed by inserting the locking piece 10 into the fourth mounting hole 14, which helps to improve the test accuracy.

[0026] In some embodiments, the locking member 10 is a screw, and the screw is threadedly connected to the fourth mounting hole 14 .

[0027] Example 2 like Figure 1 and Figure 2 As shown, the drainage assembly includes a positioning rod 12, and a third mounting hole 14 is provided on the mounting platform 4. The positioning rod 12 is cooperatively arranged in the third mounting hole 14. The third mounting hole 14 can limit the rotation of the positioning rod 12 along its axis and make the drainage needle 13 located in the plane where the axis of the support rod 5 is located.

[0028] In some embodiments, the third mounting hole 14 is a waist-shaped hole, and the waist-shaped third mounting hole 14 can limit the rotation of the positioning rod 12 along its corresponding axis, so that the drainage needle 13 is always on the same axis as the two spherical electrodes 8.

[0029] The insulating connection between the mounting platform 4 and the support rod 5 or the use of insulating material for the mounting platform 4 can effectively prevent the conductive installation platform 4 from affecting the test results.

[0030] like Figure 1 As shown, one end of the support rod 5 connected to the mounting platform 4 is provided with a connecting rod 1 for connecting to the ignition device. After the ignition device is energized, the current passes through the connecting rod 1, the support rod 5, and the mounting rod 6, and is finally gathered on the spherical electrode 8. When the charge gathered on the spherical electrode 8 reaches the breakdown voltage, an electric spark is generated between the two spherical electrodes 8 at different gaps through the drainage needle 13, thereby realizing the regulated output of the ignition device.

[0031] A method for testing the performance of an ignition device, using the above-mentioned ignition device performance testing equipment to test the ignition device, comprises the following steps: The distance between the two spherical electrodes 8 is adjusted through the mounting rod 6 and the first mounting hole 14 so that the breakdown voltage of the two electrodes meets the requirements of the test ignition voltage; The two spherical electrodes 8 are respectively connected to the output ends of the ignition device, and electric sparks are generated between the two spherical electrodes 8 at different gaps through the drainage needle 13 to achieve the regulated output of the ignition device.

[0032] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. used to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship commonly placed when the product of the invention is used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] In addition, if the terms "horizontal" or "vertical" appear in the description of the present invention, it does not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0034] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
