Izinto ezihlanganisiwe seziphenduke izinto ezilungele ukwakhiwa kwezindiza ezisezingeni eliphansi ngenxa yokukhanya kwazo, amandla aphezulu, ukumelana nokugqwala kanye nepulasitiki.Kule nkathi yomnotho osezingeni eliphansi ophishekela ukusebenza kahle, impilo yebhethri nokuvikelwa kwemvelo, ukusetshenziswa kwezinto eziyinhlanganisela akuthinti kuphela ukusebenza nokuphepha kwendiza, kodwa futhi kuyisihluthulelo sokukhuthaza ukuthuthukiswa kwemboni yonke.
I-carbon fiberimpahla eyinhlanganisela
Ngenxa yokungasindi kwayo, amandla aphezulu, ukumelana nokugqwala nezinye izici, i-carbon fibre isiphenduke into ekahle ekwenzeni indiza esezingeni eliphansi.Ayikwazi nje ukunciphisa isisindo sendiza, kodwa futhi ithuthukise ukusebenza nezinzuzo zezomnotho, futhi ibe esikhundleni esiphumelelayo sezinto zensimbi zendabuko.Ngaphezu kuka-90% wezinto eziyinhlanganisela ku-skycars yi-carbon fiber, kanti ingilazi esele iyi-fiber aircraft engu-10% ku-eV. izingxenye zesakhiwo kanye nezinhlelo ze-propulsion, ezibalelwa cishe ku-75-80%, kuyilapho izicelo zangaphakathi ezifana nemishayo nezakhiwo zezihlalo zibalelwa ku-12-14%, kanye nezinhlelo zebhethri ne-avionics akhawunti ye-8-12%.
I-Fiberingilazi eyinhlanganisela impahla
I-Fiberglass reinforced plastic (GFRP), enokumelana nokugqwala kwayo, ukumelana nokushisa okuphezulu nokuphansi, ukumelana nemisebe, izici ezivimbela ilangabi kanye nezici zokuguga, idlala indima ebalulekile ekwakhiweni kwezindiza ezinobude obuphansi njenge-drones.
Enqubweni yokukhiqiza indiza enobude obuphansi, indwangu ye-fiberglass isetshenziswa kakhulu ekwenzeni izingxenye ezibalulekile zesakhiwo njengamafreyimu omoya, amaphiko, nomsila.Izimpawu zayo ezingasindi zisiza ukuthuthukisa ukusebenza kahle kohambo lwendiza futhi zinikeze amandla aqinile esakhiwo nokuzinza.
Ezingxenyeni ezidinga ukufinyeleleka okuhle kakhulu kwegagasi, okufana nama-radome nama-fairings, ngokuvamile kusetshenziswa izinto ezihlanganisiwe ze-fiberglass. Isibonelo, i-UAV yobude obuphezulu yobude obuphezulu kanye ne-US Air Force's RQ-4 “Global Hawk” uav zisebenzisa i-carbon fibre composite materials amaphiko azo, umsila, indawo yenjini kanye ne-fuselage engemuva, kuyilapho isignali ehlanganisiwe ye-radome yenziwa i-radome ecacile ukuze kucace izinto ezibonakalayo ze-fiber composite.
Indwangu ye-Fiberglass ingasetshenziswa ukwenza ama-fairings ezindiza namafasitela, angagcini nje ngokuthuthukisa ukubukeka nobuhle bendiza, kodwa futhi athuthukise ukunethezeka kokugibela.Ngokufanayo, ekwakhiweni kwesathelayithi, indwangu yengilazi ye-fiber ingasetshenziselwa ukwakha isakhiwo sangaphandle samapaneli elanga nama-antenna, ngaleyo ndlela ithuthukise ukubukeka nokuthembeka kokusebenza kwamasathelayithi.
I-Aramid fiberimpahla eyinhlanganisela
I-aramid paper honeycomb core material eklanywe ngesakhiwo esiyi-hexagonal sekhekheba lezinyosi lemvelo le-bionic ihlonishwa kakhulu ngenxa yamandla ayo akhethekile akhethekile, ukuqina okukhethekile kanye nokuzinza kwesakhiwo.Ngaphezu kwalokho, le nto futhi inomsindo omuhle wokuvala, ukufakwa kokushisa kanye nezakhiwo ezivimbela ilangabi, futhi intuthu nobuthi obukhiqizwa ngesikhathi sokusha buphansi kakhulu. Lezi zici ziyenza ibambe indawo ekusetshenzisweni okuphezulu kwe-aerospace kanye nezindlela zokuthutha ezihamba ngesivinini esikhulu.
Nakuba izindleko ze-aramid paper honeycomb core material ziphezulu, ngokuvamile zikhethwa njengento ebalulekile engasindi yemishini ephezulu njengezindiza, imicibisholo, namasathelayithi, ikakhulukazi ekwenziweni kwezingxenye zesakhiwo ezidinga ukungena kwamagagasi e-broadband kanye nokuqina okuphezulu.
Izinzuzo ezingasindi
Njengento ebalulekile yesakhiwo se-fuselage, iphepha le-aramid lidlala indima ebalulekile ezindizeni ezongayo ezisezingeni eliphansi njenge-eVTOL, ikakhulukazi njengongqimba lwesemishi lekhekheba lezinyosi le-carbon fiber.
Emkhakheni wezimoto zasemoyeni ezingenamuntu, i-Nomex honeycomb (iphepha le-aramid) ibuye isetshenziswe kabanzi, isetshenziselwa igobolondo le-fuselage, isikhumba sephiko kanye nonqenqema oluholayo nezinye izingxenye.
Okunyesandwich izinto eziyinhlanganisela
Izindiza ezisezingeni eliphansi, njengezimoto zasemoyeni ezingenamuntu, ngaphezu kokusebenzisa izinto eziqinisiwe ezifana ne-carbon fibre, i-glass fibre kanye ne-aramid fiber ekukhiqizeni, izinto zokwakha isangweji ezifana nekhekheba lezinyosi, ifilimu, ipulasitiki eyigwebu kanye ne-foam glue nazo zisetshenziswa kabanzi.
Ekukhethweni kwezinto ze-sandwich, ezivame ukusetshenziswa yi-honeycomb sandwich (njenge-honeycomb yephepha, i-honeycomb ye-Nomex, njll.), isangweji lezinkuni (njenge-birch, i-paulownia, i-pine, i-basswood, njll.) kanye nesangweji le-foam (njenge-polyurethane, i-polyvinyl chloride, i-polystyrene foam, njll.).
Isakhiwo sesemishi legwebu sisetshenziswe kabanzi esakhiweni sama-airframes e-UAV ngenxa yezimpawu zawo zokungangeni kwamanzi nezintantayo kanye nezinzuzo zezobuchwepheshe zokukwazi ukugcwalisa imigodi yesakhiwo sangaphakathi sephiko nomsila wephiko lilonke.
Lapho uklama ama-UAV anesivinini esiphansi, izakhiwo zesemishi lezinyosi zivame ukusetshenziselwa izingxenye ezinezidingo zamandla aphansi, izimo ezivamile, izindawo ezinkulu ezigobile futhi kulula ukuzibeka, njengezindawo eziqinisa iphiko langaphambili, izindawo zokuzinzisa umsila oqondile, izindawo eziqinisa amaphiko, njll.Ezingxenyeni ezinobumo obuyinkimbinkimbi kanye nezindawo ezincane ezigobile, indawo engaphezulu ye-eleva, i-rudder, njll. Kukhethwa izakhiwo ze-sandwich ze-foam ezidinga amandla aphezulu, izakhiwo ze-sandwich zokhuni zingase zikhethwe.Kulezo zingxenye ezidinga kokubili amandla aphezulu nokuqina okuphezulu, njengesikhumba se-fuselage, i-T-beam, i-L-beam, njll., isakhiwo se-laminate sivame ukusetshenziswa.Ukwenziwa kwalezi zingxenye kudinga ukuguqulwa kwangaphambili, futhi ngokusho kwezidingo ezidingekayo zendiza, ukuqina okuqinile, ukuqina okuqinile nokugoqa okufanelekile i-fiber eqinisiwe, i-matrix material, i-fiber content kanye ne-laminate, futhi idizayine ama-engeli ahlukene okubeka, izendlalelo nokulandelana kwezingqimba, futhi zelaphe ngamazinga okushisa ahlukene kanye nezingcindezi zokucindezela.
