The impact wave pressure testing technology study of underwater shooting device

摘要

when shooting underwater, the media water around the underwater shooting device fell under the application of powder combustion gas with high temperature, high speed and high pressure, producing pressure wave. Underwater shooting is much more complicated than shooting ashore. in particular, the pulsation of pressure wave is much more prominence because of the greater intensity and inertia of water. The peak and the specific impulse of pressure wave will badly impact the environment and the operator when exceed a certain value. To avoid this phenomenon, the ways and means of testing and experimentation should be used to study this problem. This thesis introduced the make up and principle of this testing system, and elicits a corresponding conclusion via analysis of testing instance and measured data.
