Blog iyi idachokera pa kuyankhulana kwanga ndi Stefano Corvaglia, injiniya wazinthu, wotsogolera wa R&D ndi woyang'anira katundu wanzeru wa dipatimenti yokonza ndege ya Leonardo (Grottaglie, Pomigliano, Foggia, Nola Production station, kum'mwera kwa Italy), komanso kuyankhulana ndi Dr. Silvio Pappadà, kafukufuku injiniya ndi mutu.Pulojekiti ya mgwirizano pakati pa CETMA (Brindisi, Italy) ndi Leonardo.
Leonardo (Rome, Italy) ndi m'modzi mwa osewera akuluakulu padziko lonse lapansi pazamlengalenga, chitetezo ndi chitetezo, ndi chiwongola dzanja cha 13.8 biliyoni ya euro ndi antchito oposa 40,000 padziko lonse lapansi.Kampaniyi imapereka mayankho athunthu a mpweya, nthaka, nyanja, malo, maukonde ndi chitetezo, ndi machitidwe osayendetsedwa padziko lonse lapansi.Ndalama za R&D za Leonardo ndi pafupifupi ma euro 1.5 biliyoni (11% ya ndalama za 2019), omwe ali wachiwiri ku Europe komanso wachinayi padziko lonse lapansi potengera ndalama zofufuzira muzamlengalenga ndi chitetezo.

Leonardo, kudzera mu dipatimenti yake yoyendetsa ndege, amapereka mapulogalamu akuluakulu a ndege zapadziko lonse lapansi kupanga ndi kusonkhanitsa zigawo zazikulu zamagulu ndi zida zachikhalidwe, kuphatikizapo fuselage ndi mchira.

Pankhani ya zida zophatikizika, Leonardo's Aerospace Structure Division imapanga "migolo yachidutswa chimodzi" ya Boeing 787 chapakati fuselage zigawo 44 ndi 46 pa Grottaglie chomera ndi yopingasa stabilizer pa Foggia chomera ake, owerengera pafupifupi 14% ya 787 fuselage.%.Kupanga zinthu zina zophatikizika kumaphatikizapo kupanga ndi kusonkhanitsa mapiko akumbuyo a ATR ndi Airbus A220 ndege zamalonda pa Foggia Plant yake.Foggia imapanganso zigawo zamagulu a Boeing 767 ndi mapulogalamu ankhondo, kuphatikizapo Joint Strike Fighter F-35, Eurofighter Typhoon fighter, C-27J ndege zonyamula asilikali, ndi Falco Xplorer, membala waposachedwa wa banja la Falco lopangidwa ndi ndege zopanda anthu. ndi Leonardo.
"Pamodzi ndi CETMA, tikuchita zinthu zambiri, monga ma thermoplastic composites ndi resin transfer molding (RTM)," adatero Corvaglia."Cholinga chathu ndikukonzekera ntchito za R&D kuti zipangidwe munthawi yochepa kwambiri.Mu dipatimenti yathu (R&D ndi IP management), timafunafunanso matekinoloje osokonekera okhala ndi TRL yotsika (tekinoloje yokonzeka mulingo-ie, TRL yotsika ndiyotsika komanso yotalikirapo kupanga), koma tikuyembekeza kukhala opikisana kwambiri ndikupereka thandizo kwa makasitomala padziko lonse lapansi. dziko.”
Pappadà anawonjezera kuti: "Kuyambira pamene tikugwira ntchito limodzi, takhala tikugwira ntchito mwakhama kuti tichepetse ndalama komanso kuwononga chilengedwe.Tapeza kuti ma thermoplastic composites (TPC) achepetsedwa poyerekeza ndi zida za thermoset. "
Corvaglia ananena kuti: “Tinapanga matekinoloje amenewa limodzi ndi gulu la Silvio ndipo tinapanga ma batire amtundu wina woti tiziunika momwe akupangidwira.”
"CCM ndi chitsanzo chabwino pakuchita nawo limodzi," adatero Pappadà."Leonardo wazindikira zigawo zina zopangidwa ndi zida zophatikizika za thermoset.Pamodzi tinafufuza zamakono zoperekera zigawozi mu TPC, poyang'ana malo omwe ali ndi magawo ambiri pa ndege, monga mapangidwe a splicing ndi mawonekedwe osavuta a geometric.Zokwanira."
