Problems solved by technology

[0006] At present, some multi-line linear pyrotechnic devices in my country require that the asynchronous time should not exceed 1000ns. The test error of the current off-through paper target (same output terminal) is in the range of 5ns to 350ns, which affects the synchronization test of linear pyrotechnic devices. accuracy

Embodiment Construction

[0042] The present invention will be further elaborated below in conjunction with embodiment.

[0043]As shown in Fig. 1 (a) and Fig. 1 (b), a nanosecond-level ionization signal receiver for testing the working time of a multi-route linear pyrotechnic device of the present invention includes a phenolic plastic 1 and a pressure injection on the phenolic plastic 1 2N enameled wires 2, N is greater than or equal to 1, every two enameled wires 2 form a group, the distance between the two enameled wires 2 in each group is the same, 1.15cm to 1.20cm, one end is covered in phenolic plastic 1 and the end surface is connected with phenolic plastic The end face of 1 is flush, and receives the ionization signal generated when the linear pyrotechnic device is working, and the other end protrudes out of the phenolic plastic 1 as a pole pin output; the enameled wires 2 between each group are mutually backed up.

[0044] In order to ensure the test accuracy, the position accuracy of the 2N e...

Abstract

The invention relates to an ionization signal receiver, a preparation tool, a method and a pyrotechnic device testing system. The ionization signal receiver includes phenolic plastic and 2N enameled wires injected on the phenolic plastic, N is greater than or equal to 1, and every two enameled wires form a group , the distance between the two enameled wires in each group is the same, one end is wrapped in the phenolic plastic and the end face is flush with the phenolic plastic end face, to receive the ionization signal generated when the linear pyrotechnic device is working, and the other end extends out of the phenolic plastic as a pole needle output ; The enameled wires between each group are backups for each other. The preparation tooling and the preparation method ensure that the distance between two enameled wires of the same group of ionization signal receivers is 1.15 cm to 1.20 cm, and finally improve the test accuracy of the working time synchronization of the multi-line linear pyrotechnic device.

Description

technical field [0001] The invention relates to an ionization signal receiver, a preparation tool, a method and a pyrotechnic device testing system, which is suitable for testing the working time and high synchronization of multi-line pyrotechnic devices, and belongs to the technical field of pyrotechnic testing. Background technique [0002] The working time synchronization is one of the important indicators of the characteristics and functions of the pyrotechnic device. The working time of the linear pyrotechnic device is the time it takes for the detonation wave to propagate from one end of the detonating cord to the other end. Synchronization refers to the two-way or two-way When the above detonating cords receive the same amount of stimulation at the same time, the consistency of the working time of each detonating cord of the pyrotechnic device. [0003] The working time test of pyrotechnic devices in my country is now mainly tested with manual break-through paper targ...
