Abstract

Abstract

Tovalidatethefeasibilityofhigh-speedignitionbydetonationandfindouttheignition mechanism,anexperimentalsystemwasdevelopedfortheinvestigationofdetonationignitionwithan in-lineexplosiveinitiator.Thepressurechangesinthetestfacilitiesafterignitionatspecificcharges weremeasuredbythissystem.Theignitiondelaytimewasachieved0.3msbytheignitionmethod. Thecharacteristicsofpowderburningandtheattentionsinpracticalapplicationswereobtainedbythe wayofignition,suchasthestructurestrengthofthetestfacilitiesclosetotheexplosionspot,theattenuationcourseofdetonationwaveandsoon. Themechanismofthehigh-speedignitionbydetonationwasanalyzed. Theinvestigatedresultscanprovidehelpforapplyingtheignitionbydetonationto engineering.
