Technical Field

[0001] This invention belongs to the technical field of aero-engine ignition systems, specifically relating to an ignition device performance testing equipment and its performance testing method. Background Technology

[0002] The aircraft engine is the heart of an aircraft, and the engine ignition system is one of its most important components. It's an ignition source system for the main combustion chamber and afterburner, consisting of an ignition device, ignition cable, and ignition probe. The ignition device converts the aircraft's direct current (DC) or alternating current (AC) into high-voltage electricity, which is then released through the ignition cable and probe, ensuring sufficient energy to directly ignite the air-fuel mixture in the engine's combustion chamber. Understanding the basic operating parameters of the ignition device allows for reliable control of the entire ignition process.

[0003] Currently, the matching ignition nozzles can only meet the basic operating specifications of the ignition device for checking the ignition process parameters. However, the acceptance and delivery of the ignition device also requires checks on basic parameters such as open circuit, high altitude, output voltage, and working capacity. Since each ignition nozzle has its fixed ignition voltage, it cannot meet the requirements for checking all the basic parameters of the ignition device. Therefore, it is necessary to develop a performance testing device for the ignition device to solve this problem. Summary of the Invention

[0012] In some embodiments, the drainage assembly comprises a positioning rod, the mounting platform is provided with a third mounting hole, the positioning rod is fitted in the third mounting hole, the third mounting hole can limit rotation of the positioning rod along its axis and make the drainage needle located in a plane in which the axis of the support rod is located.

[0013] In some embodiments, the third mounting hole is a waist-shaped hole.

[0014] In some embodiments, the mounting platform is connected to the support rod in an insulating manner or the mounting platform is made of an insulating material.

[0015] In some embodiments, the end of the support rod connected to the mounting platform is provided with a connecting rod for connecting to the ignition device.
