Abstract

Asearlyasthe1960s,theUnitedStatesandtheSovietUnionhadbegunresearchonHall

thrusters.Today,Hallthrustersarewidelyusedinthefieldsofnorth-southpositionmaintenance,

atmosphericresistancecompensation,orbitaltransfer(orbitaltransfer)andsoon.Inrecent

years,thedevelopmentofsatellitesinChinahasgraduallyshiftedtominiaturizationandlow

cost,andtheresearchanduseofHallthrustershavegraduallyincreased.Thestorageandsupply

systemplaysaroleinstabilizingtheoutputflowofthethruster.Aftertheworkingmediumis

Inthisthesis,thetransportcharacteristicsoftheworkingfluidintheHallthrusterstorage

chamberisanalyzed.Firstly,themodelofxenonandkryptongasstorageandsupplysystemis

constructedbyusingAmesimsimulationsoftware.Theinfluenceofdifferentsystemparameters,

pipelineparametersandtanksettingsontheflowofworkingfluidsisanalyzed,andtheoutput

characteristicsofthestorageandsupplysystemwithdifferentworkingfluidsarecompared.

Theeffectsofstructuralparameters,pipelineparametersandtankinputsettingsonthefinal

outputflowrateofthestoragesystemwereobserved.Forexample,accordingtothe
