Abstract
Asearlyasthe1960s,theUnitedStatesandtheSovietUnionhadbegunresearchonHall
thrusters.Today,Hallthrustersarewidelyusedinthefieldsofnorth-southpositionmaintenance,
atmosphericresistancecompensation,orbitaltransfer(orbitaltransfer)andsoon.Inrecent
years,thedevelopmentofsatellitesinChinahasgraduallyshiftedtominiaturizationandlow
cost,andtheresearchanduseofHallthrustershavegraduallyincreased.Thestorageandsupply
systemplaysaroleinstabilizingtheoutputflowofthethruster.Aftertheworkingmediumis

dischargeisalsooneoftheimportantresearchdirections.
Inthisthesis,thetransportcharacteristicsoftheworkingfluidintheHallthrusterstorage

chamberisanalyzed.Firstly,themodelofxenonandkryptongasstorageandsupplysystemis
constructedbyusingAmesimsimulationsoftware.Theinfluenceofdifferentsystemparameters,
pipelineparametersandtanksettingsontheflowofworkingfluidsisanalyzed,andtheoutput
characteristicsofthestorageandsupplysystemwithdifferentworkingfluidsarecompared.
Theeffectsofstructuralparameters,pipelineparametersandtankinputsettingsonthefinal
outputflowrateofthestoragesystemwereobserved.Forexample,accordingtothe
