Njengoko imveliso yeenqwelo-moya ezilula isanda, ifikelela kwimveliso yonyaka yeenqwelo-moya ezingaphezu kwama-5,000 kunye nokungena kwemali yeenqwelo-moya zombane ezisuka ngokuthe nkqo kunye nokufika (eVTOL) ezingaphezulu kweebhiliyoni ezili-10 zeerandi zaseMelika, oko kwabonisa ukuba ishishini leenqwelo-moya lingena kwixesha lotshintsho. Ibhetri yintsika yolu tshintsho, kwaye ukhuseleko lwayo, ubunzima kunye nokuthembeka kwayo kuya kumisela ngokuthe ngqo ukuba isizukulwana esilandelayo seenqwelo-moya sisebenza njani. Ukuwelda kweendawo zemveli kusetyenziswa kakhulu, kodwa akunakuhlangabezana neemfuno ezingqongqo zoshishino lweenqwelo-moya oluphambili lwangoku. Kodwa iteknoloji yokuwelda ye-transistor iyichaza ngokutsha le ndawo.
Iipakethi zeebhetri zenqwelo-moya zinemfuno ephezulu kakhulu yokudibanisa umgangatho. I-aluminium yechungechunge ezintandathu (esetyenziselwa ukunciphisa ubunzima), intsimbi efakwe i-nickel (esetyenziselwa ukuphucula ukumelana nokugqwala) kunye nezixhobo ezidityanisiweyo zekopolo-aluminium zibalaseleyo. Nangona kunjalo, izixhobo zendabuko zokudibanisa amabala azinakwanelisa iimfuno zezinto ezingentla. Ukusasazwa kwamandla okudibanisa okungalinganiyo kulula ukubangela imifantu ye-splash. Emva kokudibanisa, iziphumo zokuhlolwa kwe-X-ray zibonisa ukuba ukuya kuthi ga kwi-30% yee-welds azifanelekanga. Indawo yayo echaphazeleka bubushushu (HAZ) idlula umda ongqongqo we-0.2 mm, oya konakalisa ukwakheka kweekhemikhali zebhetri kwaye ukhawulezise ukubola kwebhetri. Okubi nangakumbi, izixhobo zendabuko zokudibanisa amabala azinazo iindlela zokulandelela uxinzelelo lwe-welding ngexesha langempela, nto leyo eyenza ukuba ukujonga inkqubo kunye nedatha yokudibanisa ingabikho. Kwayeukuwelda kwe-transistorizixhobo zisombulula ngokupheleleyo eli nqanaba lentlungu ngokujonga nokurekhoda idatha yoxinzelelo lwejoyinti nganye yesolder ngexesha langempela.
Isitayile se-elektronikiumatshini wokuwelda we-transistorIsombulula la manqaku entlungu ngokulawula i-microsecond kunye nokuvelisa i-welding echanekileyo. I-inverter yayo ye-20k Hz–200kHz high frequency inokwenza i-waveform yangoku ecwangcisiweyo (i-DC, i-pulse okanye i-ramp), ngaloo ndlela ifezekise ukuchaneka kwe-welding kwe-0.05mm. Oku kunokunyusa ukuchaneka kwebhetri, okubaluleke kakhulu kukhuseleko lweenqwelo moya.
Umbane we-transistor welding usebenzisa i-IGBT kunye nezinye ii-transistors ezitshintsha ngesantya esiphezulu, ezinokukhupha i-direct current ezizinzileyo kakhulu, kwaye zixhomekeke kwitekhnoloji ye-inverter ye-frequency ephezulu (efana ne-20kHz) ukuze zenze ulawulo oluchanekileyo lwenkqubo ye-current waveform. Ingundoqo yayo ikwinkqubo yokucinezela iziphene ze-welding ngokusebenzisa ulandelelwano olupheleleyo lwenkqubo "ye-scending slope-smooth welding-smooth downside slope". Kwangaxeshanye, i-microprocessor eyakhelwe ngaphakathi kombane ijonga i-current kunye ne-voltage ngexesha langempela kwi-microsecond frequency, kwaye i-welding current "itshixiwe" ngokuqinileyo kwixabiso elimiselweyo ngokulungelelanisa ngokuguquguqukayo imeko ye-IGBT switch. Ingamelana ngempumelelo nokuphazamiseka okubangelwa lutshintsho oluguquguqukayo lokumelana kwinkqubo ye-welding, ngokusisiseko iphephe ukutshiza okugqithisileyo okubangelwa kukutshintsha ngesiquphe kwe-current, kwaye iqinisekise uzinzo olugqithisileyo lokufakwa kobushushu.
Olu phononongo lubonisa iingenelo zalo. I-Al-Ni steel joint enobukhulu obuyi-0.3mm ifikelela kwi-85% yamandla esiseko sesinyithi phantsi komgangatho we-ASTM E8, kwaye inokumelana nokungcangcazela okukhulu. Ukusebenza kwayo kakuhle kwamandla kuphezulu njenge-92%. Xa kuthelekiswa noomatshini bokuwelda bendabuko, ukusetyenziswa kwamandla kuncitshiswa nge-40%, kwaye umgca ngamnye wemveliso ophakathi unokonga i-12,000 yeedola minyaka le. Ukuthobela i-DO-160G esele ifakwe ngaphambili kunokuphucula isantya sokuqinisekiswa nge-30% kwaye kuxhaswa sisiqinisekiso sobugcisa se-EASA.
Kwabavelisi bezixhobo zokuqala zeenqwelo moya, abavelisi beebhetri kunye neelabhoratri ze-R&D, uStyler'sumatshini wokuwelda we-transistoridlula umda wezixhobo zokuwelda. Njengekhaka lokuthobela imithetho, iguqula imiqobo yolawulo ibe ziingenelo zokukhuphisana. Ukuwelda ngakunye kuba yindawo yedatha elandelekayo nefumaneka lula, ehambelana nemigangatho ye-ISO3834 kunye ne-RTCA DO-160.
Ukuwelda ngokuchanekileyo akusekho ndlela, kodwa kusisiseko sokutshintsha kweenqwelo-moya ezisuka ngokuthe nkqo kunye nokufika (eVTOL) ukusuka kwiprototype ukuya kwizithuthi zabakhweli. UStyler umema abavelisi ukuba bafumane ukuchaneka kwe-millimeter ngokuboniswa bukhoma. Fumanisa indlela itekhnoloji yethu yokuwelda ibhetri eguqula ngayo umngcipheko ube kukuthembeka. Nxibelelana nathi ukuze ufumane iinkcukacha ezithe vetshe kwaye uchaze kwakhona imigangatho yakho yokuwelda yeenqwelo-moya, ukuze yonke i-welding izalelwe ukubhabha esibhakabhakeni esiluhlaza okwesibhakabhaka.
("Isiza") senzelwe iinjongo zolwazi ngokubanzi kuphela. Lonke ulwazi olukwisiza lunikezelwa ngokunyaniseka, nangona kunjalo, asiwenzi siqinisekiso salo naluphi na uhlobo, olucacileyo okanye olungachazwanga, malunga nokuchaneka, ukwanela, ukuthembeka, ukuthembeka, ukufumaneka okanye ukuphelela kwalo naluphi na ulwazi olukwisiza.
