Description

Technical Field

[0001] The invention relates to the technical field of semi-enclosed explosive devices, in particular to a semi-enclosed explosive device used for testing the inner bore material of a gun barrel. Background Art

[0002] A semi-closed exploder is a device used in the fields of mechanics, chemical engineering and materials science. It is mainly used to handle high-pressure and high-temperature reactions, especially in cases involving combustion or explosion. Unlike a fully closed reactor, a semi-closed exploder allows a certain amount of gas or liquid to flow, but at the same time can maintain high pressure or temperature in the reaction environment, making the reaction controllable and improving efficiency.

[0003] The existing semi-enclosed explosive device is mainly used to test the performance of gunpowder primer, plasma diagnosis, and as a plasma generator, or burning rate test, pressure-temperature-time change calculation method, for rocket solid propellant velocity measurement, the main structure is as follows Figure 1 As shown, its working principle is: the rear end of the semi-closed explosive device is electrically ignited, and the gunpowder 102 burns in the space container 101. When the air pressure reaches a certain level, it breaks through the pressure control sheet 302, and the gas is discharged to obtain the performance of gunpowder combustion. The plasma generator also has the same working principle. The prior art is mainly a semi-closed explosive device or a closed explosive device with a fixed volume, which is used to test the relevant performance of gunpowder. There is no method for analyzing and testing the performance of the metal material in the inner chamber of the artillery. The main problem is to test and analyze the performance of the gunpowder material or related propellant, such as the burning rate and temperature.

[0004] The traditional gun squeeze test equipment has a relatively simple structure, such as Figure 2 As shown in the figure, its pneumatic launch simulates the process of projectile squeezing in, and it is difficult to control multiple variables at the same time or simulate the complex gas flow and chemical reaction process, and it is difficult to fully simulate the real environmental conditions when the artillery is fired, such as instantaneous high temperature, high pressure, gas flow rate and chemical reaction. This will cause the test results to deviate from the performance under actual use conditions.

[0005] In the prior art, the sealing and structural design of the equipment may cause wear or deformation after a long period of time or multiple tests, resulting in reduced sealing effect and unstable internal pressure, which in turn affects the repeatability of the test. Some test equipment has difficulty maintaining consistent test conditions when performing multiple tests, resulting in large differences between different test results. This affects the reliability and comparability of the test data. In addition, the needs of modularization and rapid replacement are not fully considered in the design of the equipment, and the internal structure may be too complex or integrated, resulting in a lot of time required to disassemble, replace and reinstall materials after each test. Especially when a large number of tests are required, the time cost is increased.

[0006] In view of the above problems, the present invention proposes a semi-enclosed explosive device for testing the inner bore material of a gun barrel. Summary of the invention
