Abstract: IntheMarsentrydeceleratelandingprogram，theparachuteisakeyinstrumentoftheaerodynamicdeceleratorsystem.BecauseoftheparticularityoftheMarsatmosphere，theparachuteusedfortheMarsmissondeploysunderthesupersonic，lowdensity，lowdynamicpressureconditions.SotheconstructionandsizingoftheMarsparachuteismuchimportant.TheMarsparachutetechnologywasinvestigatedandanalyzedbyfourtypesofparachute，consideringthediskbandarearatioandporosityofthecanopymaterial.Todeterminethedragandstaticstabilityofthevarioustypesofdisk-gap-bandparachutemodel，theMarsparachutetransoniccharacteristicstestinChinawasfirstlyconducted.Thefronttrussandwindtunnelbalancewasusedtomeasuretheaxisforceontheparachutemodel，andthephotographywasusedtoobservetheangleofattackoftheparachute.Thetestresultsshowthat，thetransonicdragcoefficientofthedisk-gap-bandparachuteaccordswiththetheoreticaloneandcansatisfytheMarsmissionrequirements.Itisalsoobservedthatthereductionofstabilityofthedisk-gap-bandparachuteisaccompaniedbytheincreasingofthedragperformance.
