EXPERIMENTAL STUDY ON SINGLEIGNITION OF MULTI-COMPONENTFUEL MIXTURE

In order to increase the explosion power of multi-component fuel mixture, a field experimental study is carried out on single ignition of a few dosage of ternary solid fuel mixture with unconfined volume dispersion, with optical and electrical testing methods. An optimized fuel mixture ratio is obtained for the test bomb. Experimental results show that the cloud dispersion effect of multi-component solid fuel mixture is better than trinitrotoluene's of the same mass. Overpressure within the explosion field of solid fuel mixture firstly decreases, then increases, and then decreases again with increase of distance, and the distribution of the overpressure field is similar. Explosion power of solid fuel mixture can be enhanced with a suitable increase of bomb density.
