Panyaya yezvigadzirwa zvakaumbwa, Leonardo's Aerospace Structure Division inogadzira "madhiramu-chimwe" eBoeing 787 central fuselage zvikamu 44 uye 46 paGrottaglie chirimwa uye zvakachinjika zvinodzikamisa paFoggia plant, inoverengera ingangoita 14% ye787 fuselage.%.Kugadzirwa kwezvimwe zvakaumbwa zvigadzirwa zvinosanganisira kugadzira uye kuunganidza bapiro rekumashure reATR uye Airbus A220 ndege yekutengeserana paFoggia Plant yayo.Foggia inogadzirawo zvikamu zvakaumbwa zveBoeing 767 uye zvirongwa zvemauto, zvinosanganisira Joint Strike Fighter F-35, Eurofighter Typhoon fighter, C-27J mauto ekufambisa ndege, uye Falco Xplorer, ichangoburwa nhengo yemhuri yeFalco isina munhu inogadzirwa. naLeonardo.
"Pamwe chete neCETMA, tiri kuita zvinhu zvakawanda, senge thermoplastic composites uye resin transfer molding (RTM)," akadaro Corvaglia.“Chinangwa chedu kugadzirira zviitwa zveR&D kuti zvigadzirwe munguva pfupi pfupi.Mudhipatimendi redu (R&D uye IP manejimendi), isu tinotsvagawo zvinokanganisa matekinoroji ane yakaderera TRL (tekinoroji yekugadzirira nhanho-kureva, Iyo yakaderera TRL iri kusimuka uye iri kure nekugadzirwa), asi isu tinotarisira kuve nemakwikwi uye nekupa rubatsiro kune vatengi vakatenderedza. nyika.”
Pappadà akawedzera kuti: “Kubva pakuedza kwedu pamwe chete, tanga tichishanda nesimba kuti tideredze mitengo uye kukanganisa kwezvakatipoteredza.Takaona kuti thermoplastic composites (TPC) yakaderedzwa kana ichienzaniswa neye thermoset zvinhu.
Corvaglia akataura kuti: "Takagadzira matekinoroji aya pamwe chete nechikwata chaSilvio uye takagadzira otomatiki mabhatiri prototypes kuti tiongorore mukugadzirwa kwawo."
"CCM muenzaniso wakanaka wekuedza kwedu pamwe chete," akadaro Pappadà."Leonardo akaona zvimwe zvinhu zvakagadzirwa ne thermoset composite zvinhu.Pamwe chete takaongorora tekinoroji yekupa zvikamu izvi muTPC, tichitarisa kune nzvimbo dzine nhamba huru yezvikamu mundege, senge splicing zvimiro uye nyore geometric maumbirwo.Zvakarurama.”
