Iyo simulator rotor-bearing system yaishandiswa ichiiswa munzvimbo dzakasiyana siyana.Kuyedzwa kwakatevera kwakapedzwa kuratidza kugona kwemaminiature thrust foil bearings zvakare.Kuwirirana kwakanaka pakati pekuyera nekuongorora kunoonekwa.Yakanyanya kupfupika rotor kukwidziridza nguva kubva pakuzorora kusvika kune yakanyanya kumhanya yakayerwa zvakare.A parallel test simulator yakashandiswa kuunganidza anopfuura 1000 ekutanga-yekumira matenderedzwa kuratidza hupenyu hwekubereka uye kupfeka.Zvichienderana nekuyedzwa kwakabudirira uku, zvinotarisirwa kuti chinangwa chekugadzira oiri isina turbocharger uye diki turbojet injini dzinoshanda nekumhanya kwakanyanya nehupenyu hurefu huchawanikwa.
Zvinodiwa zvekushanda kwepamusoro, hupenyu hurefu hurefu hweiyi kirasi itsva yemichina yakaoma.Yakajairika rolling element mabearings anopikiswa zvakanyanya nekumhanya uye mutoro unodiwa.Pamusoro pezvo, kunze kwekunge iyo nzira yemvura inogona kushandiswa semafuta, yekunze lubrication system ichaita senge.
Kubvisa mabhengi ane mafuta ane mafuta uye anosanganisirwa ekupa system anorerutsa rotor system, kuderedza huremu hwehurongwa, uye kuwedzera mashandiro asi kuchawedzera tembiricha yemukati inotakura tembiricha, izvo zvinozoda mabearings anokwanisa kushanda patembiricha inosvika 650 ° C uye nekumhanya kwakanyanya uye mitoro.Kunze kwekupukunyuka tembiricha yakanyanyisa uye nekumhanya, mabheji asina mafuta anozodawo kugashira kuvhunduka uye vibration mamiriro anowanikwa mune nharembozha.
Iko kugona kwekushandisa inowirirana foil fani kune diki turbojet injini kwakaratidzwa pasi pehupamhi hwekupisa, kuvhunduka, mutoro, uye kumhanya mamiriro.Miedzo kusvika ku150,000 rpm, pakutakura tembiricha pamusoro pe260 ° C, pasi pekuvhunduka kurodha kusvika ku90g uye marotor orientations kusanganisira 90 deg pitch uye roll, zvese zvakapedzwa zvakabudirira.Pasi pemamiriro ese akaedzwa, iyo foil inotsigirwa rotor yakaramba yakagadzikana, vibrations yaive yakaderera, uye kubereka tembiricha kwakagadzikana.Pakazere, chirongwa ichi chakapa kumashure kunodiwa kugadzira mafuta-isina turbojet kana yakakwira turbofan injini.
