[ABSTRACT]Inorder to studytheresponse characteristics of propellants to shock waves，atest method forthe shock wavesensitivityof propellnts was designed.Onthis basis，shock wavesensitivitytests were conductedonfour single base propelants，including3/1Z，4/7S，DF-12，andDF-14.Theresultsshowthat with the increaseofrestraintstrengthof the charge，the pressureaccumulationofcombustionreaction productsafter ignitionof the propelant promotes the transition fromcombustion to detonation reaction zone，resulting ina significant increase in shock wave sensitivity.When theloading density increases，theshock wavesensitivityofsinglebasepropellants issignificantlyimproved.Theobstructionandlossof energytransfer ofincident shock waves caused by loading gaps reduce the actual shock wave energy received bythe propellantbody.Meanwhile，thereleasedenergfromthecombustionreactionafterinitial ignition willbe sparsebythegaps and cannot accumulate into a detonation reaction.The shape of propelant has a significant impact on shock wave sensitivity， especially the high specific surface areaof the propelant particles plays adecisiverole in thecombustionrateafter impact ignition，promoting the transition from high-speed combustion to the chemical reaction zone of detonation.
