Njengoba ukukhiqizwa kwezindiza ezilula kwanda, kufinyelela umkhiqizo waminyaka yonke wezindiza ezingaphezu kuka-5,000 kanye nokungena kwemali yezindiza ezisuka phezulu nezifikayo zikagesi (eVTOL) ezingaphezu kwezigidigidi eziyi-10 zamaRandi aseMelika, kwabonisa ukuthi imboni yezindiza yayingena enkathini yoguquko. Iphakethe lebhethri liyisisekelo salolu shintsho, futhi ukuphepha kwalo, isisindo kanye nokuthembeka kwalo kuzonquma ngqo ukuthi kungenzeka yini isizukulwane esilandelayo sezindiza. Ukushisela kwendabuko kwezindawo ezikude kusetshenziswa kabanzi, kodwa akunakuhlangabezana nezidingo eziqinile zemboni yezindiza ethuthukisiwe yamanje. Kodwa ubuchwepheshe bokushisela be-transistor buchaza kabusha le nsimu.
Amaphakethe ebhethri ebanga lendiza anezidingo eziphezulu kakhulu zokushisela ngekhwalithi. I-aluminium enezinhla eziyisithupha (esetshenziselwa ukunciphisa isisindo), insimbi efakwe i-nickel (esetshenziselwa ukuthuthukisa ukumelana nokugqwala) kanye nezinto ezihlanganisiwe zethusi-aluminium zivamile. Kodwa-ke, imishini yokushisela yendabuko ayikwazi ukuhlangabezana nezidingo zezinto ezingenhla. Ukusatshalaliswa kwamandla okushisela okungalingani kulula ukubangela imifantu eqhekekayo. Ngemuva kokushisela, imiphumela yokuhlolwa kwe-X-ray ikhombisa ukuthi ama-weld afinyelela ku-30% awafaneleki. Indawo yayo ethintekile ekushiseni (i-HAZ) idlula umkhawulo oqinile ongu-0.2 mm, okuzolimaza ukwakheka kwamakhemikhali ebhethri futhi kusheshise ukubola kwebhethri. Okubi nakakhulu, imishini yokushisela yendabuko yokushisela ayinakho ukulandeleka kwesikhathi sangempela kwamapharamitha okucindezela ukushisela, okwenza ukuqapha inqubo kanye nedatha yokushisela ingabi khona. Futhiukushisela kwe-transistorimishini ixazulula ngokuphelele leli phuzu lobuhlungu ngokuqapha nokurekhoda idatha yokucindezela kwejoyinti ngalinye le-solder ngesikhathi sangempela.
Isitayela se-Electronic'umshini wokushisela we-transistorIxazulula la maphuzu obuhlungu ngokulawula i-microsecond kanye nobuchwepheshe bokushisela ngokunemba. I-inverter yayo yemvamisa ephezulu engu-20k Hz–200kHz ingenza i-waveform yamanje ehlelekile (i-DC, i-pulse noma i-ramp), ngaleyo ndlela ifinyelele ukunemba kokushisela okungu-0.05mm. Okungakhulisa ukunemba kwebhethri, okubaluleke kakhulu ekuphepheni kwezindiza.
Ukunikezwa kwamandla okushisela i-transistor kusebenzisa i-IGBT kanye namanye ama-transistor ashintsha ngesivinini esikhulu, angakhipha ugesi oqondile ozinzile kakhulu, futhi athembele kubuchwepheshe be-inverter obunemvamisa ephezulu (njenge-20kHz) ukuze kufezwe ukulawulwa okunembile kokuhlela kwesimo segagasi lamanje. Ingqikithi yayo itholakala ekucindezelweni okuhlelekile kokukhubazeka kokushisela ngokusebenzisa ukulandelana kwenqubo ephelele "yokwehla kancane kancane kokwehla kancane kancane kokwehla kancane kancane". Ngesikhathi esifanayo, i-microprocessor eyakhelwe ngaphakathi kokunikezwa kwamandla iqapha ugesi kanye ne-voltage ngesikhathi sangempela ku-microsecond frequency, futhi ugesi wamanje "uvaliwe" ngokuqinile ngenani elibekiwe ngokulungisa ngokuguquguqukayo isimo sokushintsha kwe-IGBT. Ingamelana ngempumelelo nokuphazamiseka okubangelwa ushintsho oluguquguqukayo lokumelana enqubweni yokushisela, igweme ngokuyisisekelo ukuchitheka ngokweqile okubangelwa ushintsho oluzumayo lwamanje, futhi iqinisekise ukuzinza okukhulu kokufakwa kokushisa.
Ucwaningo lwecala luqokomisa izinzuzo zalo. I-Al-Ni steel joint engu-0.3mm ubukhulu ifinyelela ku-85% wamandla ensimbi eyisisekelo ngaphansi kwezinga le-ASTM E8, futhi ingamelana nokudlidliza okukhulu. Ukusebenza kahle kwamandla ayo kuphezulu njengo-92%. Uma kuqhathaniswa nemishini yokushisela yendabuko, ukusetshenziswa kwamandla kuncishiswa ngo-40%, futhi umugqa ngamunye wokukhiqiza ophakathi nendawo ungonga amadola ayi-12,000 njalo ngonyaka. Ukuhambisana ne-DO-160G okufakwe ngaphambilini kungathuthukisa isivinini sokuqinisekiswa ngo-30% futhi kusekelwa isitifiketi sobuchwepheshe se-EASA.
Kwabakhiqizi bemishini yokuqala yezindiza, abakhiqizi bamabhethri kanye namalebhu e-R&D, i-Styler'sumshini wokushisela we-transistoridlula ububanzi bamathuluzi okushisela. Njengesivikelo sokuthobela imithetho, iguqula izithiyo zomthetho zibe izinzuzo zokuncintisana. Ukushisela ngakunye kuba iphuzu ledatha elilandelekayo nelitholakala kalula, elihambisana nezindinganiso ze-ISO3834 kanye ne-RTCA DO-160.
Ukushisela okunembile akuseyona inketho, kodwa kuyisisekelo sokushintsha kwezindiza ezisuka phezulu kanye nezokufika (eVTOL) zikagesi kusuka kumodeli kuya kubagibeli. UStyler umema abakhiqizi ukuthi babone ukunemba kwe-millimeter ngokuboniswa bukhoma. Thola ukuthi ubuchwepheshe bethu bokushisela ibhethri buguqula kanjani ingozi ibe ukuthembeka. Xhumana nathi ukuze uthole imininingwane eyengeziwe futhi uchaze kabusha amazinga akho okushisela ezindiza, ukuze konke ukushisela kuzelwe ukundiza esibhakabhakeni esiluhlaza okwesibhakabhaka.

Lonke ulwazi olukuSayithi lunikezwa ngokwethembeka, nokho, asenzi simemezelo noma iwaranti yanoma yiluphi uhlobo, olucacile noma olucashile, mayelana nokunemba, ukufaneleka, ubuqiniso, ukuthembeka, ukutholakala noma ukuphelela kwanoma yiluphi ulwazi olukuSayithi.
