The Study on Detonation Front Shape of a Charge Shot by High-Speed Photography

In order to obtain the detonation front shape and spreading process of detonation wave, Rotating mirror multi-streak technique was used to shoot the detonation process of charge initiated from three points by high-speed photography technique. The record negative was read and these data were analyzed. The time differences of zero-time points and t-y coordinate curve were educed, and the chart of detonation wave shape was drew. The result provides a gist for warhead design. A method for analyzing and studying wave shape is offered.
