Research on energy release characteristics of shaped charge particle jets of Ni/Al reaction material
To study the energy release law of Ni/Al reactive material focused particle flow at different positions,three types of nickel aluminum molar ratios of 2∶1,1∶1,and 1∶2 reactive material drug masks were prepared using cold pressing technology.The damage and overpressure of Ni/Al reactive material focused particle flow on the interval target in the sealed tank were tested using a continuous sealed tank overpressure testing system,and its energy release behavior was explored.The results show that with the increase of Al content,the destructive effect of the concentrated energy particle flow on the spaced target plate first decreases and then increases.In the front sealed tank,the concentrated energy particle flow with a nickel aluminum molar ratio of 1∶1 releases the most energy and has the highest chemical reaction efficiency,which is 57.4% .In the rear sealed tank,the highest energy release and total energy release are achieved when the nickel aluminum molar ratio is 2∶1,with a total energy release of 23.12 kJ.
