Study on the Combustion Mechanism and Models of Gunpowder Composite Welding Rod

Abstract:

The physical model of the flame of gunpowder composite welding rod (GCWR) is built based on the flame topography and the combustion mechanism of thermite. The chemical reactions in different flame regions are fixed with the physical model, combustion characteristics of thermite and gunpowder combustion theory. The combustion mathematic model on the relationship of combustion velocity of GCWR with thermite content is fixed with the concept of unit volume combustion heat. At last, the results of the test indicate that the rates of combustion obtained by theoretical arithmetic and test are similar.
