Ariko, nigute iki gicuruzwa gishya kigereranya na CCM Xperion (ubu ni XELIS, Markdorf, Ubudage) yakoresheje imyaka irenga icumi?Pappadà yagize ati: “Twashyizeho uburyo bwo gusesengura no kubara bushobora guhanura inenge nk'ubusa.”Ati: “Twakoranye na Leonardo na kaminuza ya Salento (Lecce, mu Butaliyani) kugira ngo dusobanukirwe ibipimo n'ingaruka zabyo ku bwiza.Dukoresha ubu buryo kugirango dutezimbere CCM nshya, aho dushobora kugira umubyimba muremure ariko nanone dushobora kugera kubwiza buhanitse.Hamwe nizi ngero, ntidushobora gusa guhindura ubushyuhe nigitutu, ariko kandi tunashobora gukoresha uburyo bwabo bwo gusaba.Urashobora guteza imbere tekinike nyinshi zo gukwirakwiza ubushyuhe hamwe nigitutu.Icyakora, tugomba gusobanukirwa n'ingaruka z'ibi bintu ku miterere ya mashini no gukura kw'imiterere y'inzego zose. ”
Pappadà yakomeje agira ati: “Ikoranabuhanga ryacu rirahinduka.Mu buryo nk'ubwo, CCM yatejwe imbere hashize imyaka 20, ariko nta makuru abivugaho kubera ko amasosiyete make ayakoresha adahuje ubumenyi n'ubuhanga.Tugomba rero guhera ku ntangiriro, gusa Dushingiye ku myumvire yacu y'ibikoresho hamwe no gutunganya. ”
Corvaglia yagize ati: "Ubu turi kunyura muri gahunda z'imbere no gukorana n'abakiriya kugira ngo dushakishe ibice by'ikoranabuhanga rishya."Ati: “Ibi bice birashobora gukenera gusubirwamo no gusabwa mbere yuko umusaruro utangira.”Kubera iki?Ati: “Intego ni ugukora indege yoroshye bishoboka, ariko ku giciro cyo gupiganwa.Kubwibyo, tugomba nanone guhuza ubunini.Icyakora, dushobora gusanga igice kimwe gishobora kugabanya ibiro, cyangwa kumenya ibice byinshi bifite imiterere isa, bishobora kuzigama amafaranga menshi. ”
Yashimangiye ko kugeza ubu, iryo koranabuhanga ryabaye mu maboko y’abantu bake.Yakomeje agira ati: "Ariko twateje imbere ubundi buryo bwo gukoresha ikoranabuhanga kugira ngo twongere ibyo bikorwa twongeyeho uburyo bwo gutangaza amakuru.Dushyiramo laminate iringaniye hanyuma tugakuramo igice cyayo, twiteguye gukoresha.Turi muburyo bwo guhindura ibice no guteza imbere ibice bisa cyangwa byanditse.Icyiciro cya CCM. ”
Pappadà ati: "Ubu dufite umurongo wa CCM woroshye cyane muri CETMA."Ati: “Hano dushobora gukoresha imikazo itandukanye nkuko bikenewe kugirango tugere ku miterere igoye.Umurongo wibicuruzwa tuzatezimbere hamwe na Leonardo tuzibanda cyane kubujuje ibice byihariye bisabwa.Twizera ko imirongo itandukanye ya CCM ishobora gukoreshwa kumurongo ugororotse na L-shusho aho kuba imiterere igoye.Muri ubu buryo, ugereranije n’imashini nini zikoreshwa muri iki gihe kugira ngo habeho ibice bigoye bya geometrike ya TPC, dushobora gutuma igiciro cy’ibikoresho gikomeza kuba gito. ”
CETMA ikoresha CCM kugirango ikore imigozi hamwe na paneli biva muri karuboni fibre / PEKK kaseti imwe, hanyuma ikoresha induction yo gusudira yiyi keel bundle yerekanwe kugirango ibahuze mumushinga wa Clean Sky 2 KEELBEMAN ucungwa na EURECAT.Inkomoko | ”Icyerekezo cyo gusudira ibiti bya termoplastique kiragaragara.”
Pappadà yagize ati: "Gusudira induction birashimishije cyane kubikoresho byinshi, kubera ko ubushyuhe bushobora guhinduka no kugenzurwa neza, ubushyuhe bwihuse kandi kugenzura neza."Ati: "Hamwe na Leonardo, twateje imbere gusudira induction kugirango twinjire mu bice bya TPC.Ariko ubu turimo gutekereza gukoresha gusudira induction kugirango duhuze (ISC) ya kaseti ya TPC.Kugira ngo ibyo bishoboke, twateguye kaseti nshya ya karubone, Irashobora gushyuha vuba cyane no gusudira induction ukoresheje imashini idasanzwe.Kaseti ikoresha ibikoresho fatizo kimwe na kaseti yubucuruzi, ariko ifite imyubakire itandukanye kugirango itezimbere ubushyuhe bwa electronique.Mugihe tunonosora imiterere yubukanishi, turimo gutekereza kandi kuburyo bwo kugerageza kuzuza ibisabwa bitandukanye, nkuburyo bwo kubikemura neza kandi neza binyuze mumashanyarazi. ”
Yagaragaje ko bigoye kugera kuri ISC hamwe na kaseti ya TPC n'umusaruro mwiza.Ati: "Kugirango uyikoreshe mu nganda, ugomba gushyushya no gukonja vuba kandi ugashyiraho igitutu muburyo bugenzurwa cyane.Ku bw'ivyo, twarafashe ingingo yo gukoresha gusudira induction kugira ngo dushushe agace gato aho ibintu bihurira, hamwe na Laminates isigaye ikonja. ”Pappadà avuga ko TRL yo gusudira induction ikoreshwa mu guterana iri hejuru.“
Kwishyira hamwe kurubuga ukoresheje gushyushya induction bisa nkaho bitesha umutwe-ubungubu, ntayindi OEM cyangwa abatanga urwego babikora kumugaragaro.Corvaglia yagize ati: "Yego, iyi ishobora kuba ikoranabuhanga rihungabanya."Ati: “Twasabye patenti ku mashini n'ibikoresho.Intego yacu nigicuruzwa cyagereranywa nibikoresho bya thermoset.Abantu benshi bagerageza gukoresha TPC kuri AFP (Automatic Fiber Placement), ariko intambwe ya kabiri igomba guhuzwa.Kubijyanye na geometrie, Iyi ni imbogamizi nini mubijyanye nigiciro, igihe cyinzira nubunini bwigice.Mubyukuri, dushobora guhindura uburyo dukora ibice byo mu kirere. ”
Usibye thermoplastique, Leonardo akomeje gukora ubushakashatsi ku ikoranabuhanga rya RTM.Ati: "Aka ni akandi gace dukorana na CETMA, kandi iterambere rishya rishingiye ku ikoranabuhanga rya kera (SQRTM muri uru rubanza) ryatanzwe.Impapuro zujuje ibyangombwa bisubirwamo byakozwe mbere na Radius Engineering (Salt Lake City, Utah, USA) (SQRTM).Corvaglia yagize ati: “Ni ngombwa kugira uburyo bwa autoclave (OOA) butuma dukoresha ibikoresho bimaze kuzuzwa.Ati: “Ibi kandi bidufasha gukoresha progaramu ya progaramu ifite imiterere izwi neza.Twifashishije ubwo buhanga mugushushanya, kwerekana no gusaba ipatanti yama kadirishya yindege.“
Nubwo COVID-19, CETMA iracyatunganya gahunda ya Leonardo, hano herekanwa imikoreshereze ya SQRTM kugirango ikore idirishya ryindege kugirango igere kubice bitagira inenge kandi byihute mbere yo gukora ugereranije nubuhanga gakondo bwa RTM.Kubwibyo, Leonardo arashobora gusimbuza ibyuma bigoye hamwe nibice bya mesh bitarinze gutunganywa.Inkomoko |CETMA, Leonardo.
Pappadà yerekanye ati: “Ubu ni n'ikoranabuhanga rya kera, ariko iyo ugiye kuri interineti, ntushobora kubona amakuru ajyanye n'ikoranabuhanga.”Na none kandi, dukoresha uburyo bwo gusesengura kugirango tumenye kandi tunoze ibipimo byimikorere.Hamwe nikoranabuhanga, turashobora kubona resin nziza yo gukwirakwiza-ntahantu humye cyangwa gukusanya resin-kandi hafi ya zeru.Kuberako dushobora kugenzura ibirimo fibre, dushobora kubyara ibintu byinshi byubatswe, kandi tekinoroji irashobora gukoreshwa mugukora imiterere igoye.Dukoresha ibikoresho bimwe byujuje ibyangombwa byo gukiza autoclave, ariko dukoreshe uburyo bwa OOA, ariko urashobora kandi gufata icyemezo cyo gukoresha imiti yihuta yo gukiza kugirango ugabanye igihe cyizuba kugeza kuminota mike.“
Corvaglia yagize ati: "Ndetse na prereg iriho ubu, twagabanije igihe cyo gukira.""Kurugero, ugereranije na autoclave isanzwe yamasaha 8-10, kubice nkibikoresho byamadirishya, SQRTM irashobora gukoreshwa mumasaha 3-4.Ubushyuhe nigitutu bikoreshwa mubice, kandi ubushyuhe bwo kuba buke.Byongeye kandi, gushyushya amazi ya resin muri autoclave byihuta kuruta ikirere, kandi ubwiza bwibice nabwo ni bwiza, bukaba bugira akamaro cyane cyane kumiterere.Nta rework, hafi ya zeru nubuziranenge bwubuso buhebuje, kuko igikoresho kiri muri Igenzura, ntabwo umufuka wa vacuum.
Leonardo akoresha ikoranabuhanga ritandukanye mu guhanga udushya.Bitewe niterambere ryihuse ryikoranabuhanga, ryizera ko ishoramari ryibyago byinshi R&D (TRL yo hasi) ari ngombwa mugutezimbere tekinolojiya mishya ikenewe kubicuruzwa bizaza, birenze ubushobozi bwiterambere ryiyongera (mugihe gito) ibicuruzwa bihari bimaze gutunga .Igishushanyo mbonera cya Leonardo 2030 R&D gikomatanya guhuza ingamba zigihe gito nigihe kirekire, nicyerekezo gihuriweho nisosiyete irambye kandi irushanwa.
Muri gahunda, izashyira ahagaragara Leonardo Labs, umuyoboro mpuzamahanga wa laboratoire ya R&D igamije R&D no guhanga udushya.Muri 2020, isosiyete izashaka gufungura laboratoire esheshatu za mbere za Leonardo muri Milan, Turin, Genoa, Roma, Naples na Taranto, kandi irimo gushaka abashakashatsi 68 (Leonardo Research Fellows) bafite ubumenyi mu bice bikurikira): Sisitemu 36 y’ubwenge yigenga kuri imyanya yubwenge yubukorikori, isesengura ryamakuru 15 manini, 6 ikora mudasobwa ikora cyane, amashanyarazi 4 yindege yamashanyarazi, ibikoresho 5 nuburyo, na tekinoroji ya kwant 2.Laboratoire ya Leonardo izagira uruhare mu guhanga udushya no gushyiraho ikoranabuhanga rya Leonardo.
