    Abstract
  • Byusingthephotoelectric method,thesteady-statedetonationvelocitiesandthecorrespondingwaveshapesweremeasuredfortheJBO- 9021ratestickswiththediametersof10,15and 30mm,respectively,andintheJBO-9021ratesticksthemassfractionsofTATB,HMXandF2314 were80%,15%and5%,respectively,atroomtemperature.Ananalyticexpressionwasfittedtothe wavefrontdata.Andbasedontheanalyticexpression,therelationwasobtainedbetweenthenormal velocityofthewavefrontanditslocalcurvature.Theinvestigatedresultdisplaysthatthesteady-state detonationvelocityoftheJBO-9021explosiveincreaseswiththeincreaseofthediameteroftheJBO- 9021ratestick.ThedetonationwaveoftheJBO-9021explosiveisfatterthanthatoftheJB-9014explosiveinwhichthemassfractionsofTATBandF2314are95% and5%,respectively.Consequently, thenonidealspreadcharacteristicsofthedetonationwavesweaken.
