Description

Technical Field

[0001] The invention mainly relates to the technical field of aircraft maintenance, and in particular to an aircraft signal gun simulation device and a testing method. Background Art

[0002] like Figure 1 As shown in the figure, during the aircraft maintenance process, it is necessary to conduct a power-on test on the signal gun of a large aircraft to ensure that the aircraft can accurately transmit signals in combat. Therefore, ensuring that the lines and signal guns are intact is important for ensuring aircraft safety. However, after each power-on, the signal gun needs to be disassembled to confirm which electric detonator is ignited, and then compared with the on-board switch to see if it is correctly ignited. For military armament support, the operation is too cumbersome, the safety factor is low, and the test cost is too high.

[0003] Specifically, the existing operation method process is as follows Figure 3 As shown: one person in the cabin and one person near the signal gun. After the aircraft is powered on, the crew turns on the power supply, turns on the main switch of the signal gun, and presses the corresponding switch on the signal gun control box (such as Figure 2 As shown, after the person at the signal gun smells gunpowder or hears a clear firing sound, he confirms that the firing pin is fired and contacts the personnel on board to disconnect the power supply. The person at the signal gun removes the signal gun and checks the fired electric detonator and compares it with the switch on the control box pressed on board. If the two are consistent, it means that the power supply is intact. If they are inconsistent, it is a fault. Refill the electric detonator and reinstall the signal gun. A total of 15 times of disassembly and assembly without faults are performed. Repeat all the previous power-on processes until all combinations are powered on. Disconnect the power supply on board, empty all the electric detonators in the signal gun, and install the signal gun.

[0004] The above operation process has the following disadvantages:

[0005] 1. During the power-on test of the signal gun, it is impossible to accurately confirm which signal flare's detonator has been punctured. There is only the sound and smell of gunpowder, but no other obvious features to determine which detonator in the red, yellow, green, or white signal flares has been activated. The signal gun needs to be removed to see which detonator has been activated, and repeated measurements cannot be performed.

[0006] 2. It is not easy to repeatedly measure the four signals of red, yellow, green and white. If you want to achieve repeated measurement, you must repeatedly disassemble and assemble. According to the mathematical combination, there are a total of There are so many combinations, 15 in total, which means that each signal gun group uses 32 electric detonators each time it is powered on. The other three signal guns probably need nearly 100 detonators each time they are powered on, plus inspection and inspection, acceptance at the flight test station, inspection and inspection at the flight test station, and acceptance by the troops, a total of 5 times, the total cost is high if there is no malfunction.

[0007] 3. Multiple measurements mean that the signal gun needs to be disassembled and assembled multiple times to load the electric detonator. The work is cumbersome and cannot be completed in one test, which increases labor costs. Replacing gunpowder will increase risks.

[0008] 4. Repeated use of gunpowder detonators pollutes the environment. Summary of the invention

[0009] In view of the technical problems existing in the prior art, the present invention provides an aircraft signal gun simulation device and a testing method which are low in cost and easy to operate.

[0010] In order to solve the above technical problems, the technical solution proposed by the present invention is:

[0020] Preferably, the aircraft signal gun simulation device is removed, the signal gun is installed, and electric detonators are loaded into the signal gun. The power is turned on once. If the electric detonators can be normally ignited, it means that the actual gunpowder is energized and intact. The onboard power is disconnected, all the signal gun detonators are cleared, and the whole machine is powered on.

The electric detonator can be judged by the lighting situation, and then the integrity of the on-board line can be judged by pressing the button.

[0036] The present invention converts the sound signal into a light signal, and can easily identify which flare is triggered without disassembly or assembly.

[0037] The present invention adopts an equivalent substitution method, using a corresponding light bulb to replace the corresponding electric detonator, and the whole process does not require disassembly and assembly, and all combinations are Just press it randomly to solve all power-on projects at one time; you only need to install the detonator for a final test after the power-on is completed, which saves costs.
