Problems solved by technology

[0004] But it has the following deficiencies: (1) the camera B door method and the drum photography method can only achieve the visual capture and image-based analysis of the muzzle smoke, but cannot do the quantitative analysis of the smoke; (2) This method has relatively high requirements for the test environment, and the intensity of light has a greater impact on the experiment; (3) The smoke is fused with the air during the diffusion process, which has an impact on the concentration and purity of the smoke

Abstract

The invention discloses a portable muzzle smoke testing device. The device comprises a smoke collecting box [1] for collecting muzzle smoke and a bullet collector [2] for collecting bullets, wherein the bullet collector [2] comprises a bullet collecting box [21] and a bullet collecting box cover plate [22] hinged with the bullet collecting box [21], and the bullet collecting box [21] is filled with a damping material [23]; the smoke collecting box [1] comprises a box body [11], a sealing assembly [12], an exhaust device [13], a pressure relief device [14], a high compactness plate [15], a fixing plate [16], an upper leans seat assembly [17] and a lower lens seat assembly [18]; the sealing assembly [12] is fixedly connected with the front end of the box body [11] in a closed manner, the high compactness plate [15] is pressed against the back end of the box body [11] through the fixing plate [16], and the exhaust device [13] and the pressure relief device [14] are fixed on the side surface of the box body [11] and communicated with the inside of the box body. The smoke testing device can perform quantitative analysis on muzzle smoke, has the low requirement for test light rays and can obtain accurate results.

Description

technical field [0001] The invention belongs to the technical field of automatic weapon testing equipment, in particular to a portable muzzle smoke testing device with good sealing performance, high experimental efficiency and good safety. Background technique [0002] Muzzle smoke is one of the important emission traces in the process of gun shooting, and its size can reflect the completeness of gunpowder combustion and energy utilization. Therefore, it is of great significance to quantitatively test muzzle smoke. Because muzzle smoke is a substance with uncertainty in time and space, it has the characteristics of short generation time, fast diffusion, and difficulty in capturing, which brings great difficulties to the detection of muzzle smoke. [0003] The article "Research on Muzzle Flame Test Method" (Kong Deren, Meng Yingjun, Li Yongxin, Zhang Yue, Journal of Testing Technology, 1998) describes the use of camera B door method and drum photography method to capture and ...
