Experimental Studies Of The Testing Of Pyrotechnic Deflagration Velocity By Optical Fiber

A new method of testing of deflagration velocity of pyrotechnic composition mainly contain Al/KClO4 by optical fiber is presented. The diversification process of the velocity is observed in this experiment, also including the relative power of pyrotechnic flash on the different steps of the deflagration. Under low pressure, the deflagration velocity is reduced with the increasing of the loading density, and is increased under high pressure.
