Isistimu ephethe i-rotor-simulator yayisetshenziswa ngenkathi ibekwe ezindaweni ezihlukahlukene. Ukuhlolwa okwalandela kwaqedwa ukuze kuboniswe amandla ama-foil thrust bearings amancane. Ukuhlobana okuhle phakathi kokulinganisa nokuhlaziya kuyabonwa. Izikhathi ezimfushane kakhulu zokusheshisa i-rotor ukusuka ekuphumuleni kuye kwisivinini esiphezulu nazo zikalwa. Isifanisi sokuhlola esihambisanayo sisetshenziswe ukuqongelela imijikelezo yokuqala yokuma engaphezu kuka-1000 ukuze kuboniswe impilo yokuthwala nokumboza. Ngokusekelwe kulokhu kuhlolwa okuyimpumelelo, kulindeleke ukuthi umgomo wokuthuthukisa ama-turbocharger angenawo uwoyela kanye nezinjini ezincane ze-turbojet ezisebenza ngesivinini esinempilo ende izofezwa.
Izidingo zokusebenza okuphezulu, ama-bearings wempilo ende yalesi sigaba esisha semishini zinzima. Amabheringi ajwayelekile aginqikayo abhekene nenselelo enkulu ngenxa yesivinini namandla omthwalo odingekayo. Ukwengeza, ngaphandle uma uketshezi lwenqubo lungasetshenziswa njengento yokuthambisa, uhlelo lokuthambisa lwangaphandle luyocishe luqiniseke.
Ukuqeda ama-bearings agcotshwe uwoyela kanye nesistimu yokuhlinzeka ehambisanayo kuzokwenza lula uhlelo lwe-rotor, kunciphise isisindo sohlelo, futhi kuthuthukise ukusebenza kodwa kuzokhuphula izinga lokushisa langaphakathi legumbi elithwala uwoyela, okuzogcina kudinga ama-bearings akwazi ukusebenza emazingeni okushisa afinyelela ku-650 ° C futhi ngesivinini esikhulu futhi imithwalo. Ngaphandle kokusinda emazingeni okushisa adlulele kanye nesivinini, ama-bearings angenawo uwoyela azodinga futhi ukubhekana nezimo zokushaqeka nokudlidliza ezitholakala ezinhlelweni zeselula.
Ukuba nokwenzeka kokufaka ama-foil bearings athobelayo ezinjinini ezincane ze-turbojet kuboniswe ngaphansi kwezimo ezihlukahlukene zokushisa, ukushaqeka, umthwalo, kanye nesivinini. Ukuhlola ukuya ku-150,000 rpm, emazingeni okushisa angaphezu kuka-260°C, ngaphansi kokulayisha ukushaqeka ku-90g kanye nokuma kwe-rotor okuhlanganisa i-90 deg pitch and roll, konke kwaqedwa ngempumelelo. Ngaphansi kwazo zonke izimo ezihloliwe, i-foil ephethe i-rotor esekelwe yahlala izinzile, ukudlidliza kwakuphansi, futhi amazinga okushisa okuthwala ayezinzile. Sekukonke, lolu hlelo lunikeze isizinda esidingekayo ukuze kwakhiwe i-turbojet engenawo uwoyela ngokuphelele noma injini ye-turbofan esebenza kahle kakhulu.
