Abstract

High-speed camera technique is widely applied to study various explosion processes and principle. As one of the applications, a MEMRECAM HX-7 high speed camera is combined with a HX-3 high speed camera to simultaneously test the explosion process of an analog smoke projectile filled with carbon-based smoke agent. The MEMRECAM HX-7 high speed camera is used to monitor the forming process of the original smoke cloud, which highest resolution is 5 mega pixels, the maximum speed reaches 200 thousands fps, the photographic speed reaches 2000 fps when the resolution is 1920×1080. In comparison, the MEMRECAM HX-3 high speed camera is used to record the breaking process of the projectile’s shell, which has a higher photographic speed and sensitivity, the maximum speed reaches 1.3 million fps, the photographic speed reaches 50000 fps when the resolution is 448×328. By the experimental results, the explosion process of the smoke projectile may be simultaneously recorded by the two high speed cameras at 50000fps and 2000fps. By the analysis on sequence images, the expansion and breaking process of the projectile’s shell has been observed while the explosion forming process of the original smoke cloud is clearly observed.
