Izinto ezihlanganisiweyo ziye zaba yinto efanelekileyo yokwenza inqwelomoya ephantsi ngenxa yobunzima bayo, amandla aphezulu, ukuxhathisa ukubola kunye neplastiki. Kweli xesha loqoqosho oluphantsi olulandela ukusebenza kakuhle, ubomi bebhetri kunye nokukhuselwa kwendalo, ukusetyenziswa kwezinto ezidibeneyo akuchaphazeli kuphela ukusebenza kunye nokhuseleko lwenqwelomoya, kodwa kwakhona isitshixo sokukhuthaza uphuhliso lweshishini lonke.
I-carbon fiberimathiriyeli edibeneyo
Ngenxa yobunzima bayo, amandla aphezulu, ukuxhathisa kwe-corrosion kunye nezinye iimpawu, i-carbon fiber iye yaba yinto efanelekileyo yokwenziwa kweenqwelo-moya eziphantsi. amacandelo ezakhiwo kunye neenkqubo zokuqhubela phambili, i-accounting malunga ne-75-80%, ngelixa izicelo zangaphakathi ezifana nemigangatho kunye nezakhiwo zokuhlala zibandakanya i-12-14%, kunye neenkqubo zebhetri kunye nezixhobo ze-avionics ze-8-12%.
Ifayibhaizinto zeglasi edibeneyo
I-Fiberglass eyomeleziweyo yeplastiki (i-GFRP), kunye nokumelana nokunyuka kwe-corrosion, ukumelana nobushushu obuphezulu kunye nokuphantsi, ukumelana nemitha, i-flame retardant kunye neempawu ezichasayo, idlala indima ebalulekileyo ekwenziweni kweenqwelomoya ezisezantsi ezifana ne-drones.
Kwinkqubo yokuvelisa inqwelo-moya ephantsi, ilaphu le-fiberglass lisetyenziswa kakhulu ekwenzeni amacandelo abalulekileyo anjenge-airframes, amaphiko, kunye nomsila.Iimpawu zayo ezikhaphukhaphu zinceda ekuphuculeni ukuhamba kakuhle kwenqwelo-moya kwaye zibonelele ngamandla esakhiwo esomeleleyo kunye nokuzinza.
Kuba amacandelo afuna permeability amaza egqwesileyo, ezifana radomes kunye fairings, fibreglass composite materials are usually used.Ngokomzekelo, i-high-altitude long-range UAV and the US Air Force's RQ-4 “Global Hawk” uav use carbon fiber composite materials for their wings, umsila, i-injini compartment kunye ne-fuselage yangasemva, ngelixa i-fuselage ye-fayibha ecacileyo yenziwe i-fiberglass ecacileyo kunye ne-fiberglass ecacileyo yenziwe i-fiberglass ecacileyo kunye ne-fiberglass ecacileyo.
Ilaphu le-Fiberglass lingasetyenziselwa ukwenza i-aircraft fairings kunye neefestile, ezingagcini nje ukwandisa ukubonakala kunye nobuhle benqwelo-moya, kodwa kwandisa induduzo yokukhwela.Ngokufanayo, kwi-design satellite, i-glass fiber cloth ingasetyenziselwa ukwakha isakhiwo sangaphandle seepaneli zelanga kunye ne-eriyali, ngaloo ndlela iphucula ukubonakala kunye nokuthembeka kokusebenza kweesathelayithi.
Ifayibha yeAramidimathiriyeli edibeneyo
I-aramid ye-honeycomb yephepha le-honeycomb ye-core material eyenzelwe kunye nesakhiwo se-hexagonal ye-bionic ye-honeycomb yendalo yobusi ihlonishwa kakhulu ngenxa yamandla ayo athile abalaseleyo, ukuqina okuthe ngqo kunye nokuzinza kwesakhiwo.Ukongezelela, le nto iphinda ibe nesandi esilungileyo sokufakelwa kwesandi, ukufudumeza ubushushu kunye neempawu ze-flame retardant, kunye nomsi kunye netyhefu eyenziwa ngexesha lokutsha liphantsi kakhulu. Ezi mpawu zenza ukuba kuthathe indawo kwizicelo eziphezulu ze-aerospace kunye neendlela zokuthutha ezihamba ngesantya esiphezulu.
Nangona ixabiso le-aramid ye-honeycomb ye-honeycomb core material liphezulu, lihlala likhethwa njengeyona nto ilula kakhulu kwizixhobo eziphezulu ezifana neenqwelomoya, imijukujelwa, kunye neesathelayithi, ngakumbi ekwenziweni kwezinto eziyimfuneko ezifuna ukunyanzeliswa kwamaza e-broadband kunye nokuqina okuphezulu.
Izibonelelo ezilula
Njengesixhobo esibalulekileyo sokwakheka kwe-fuselage, iphepha le-aramid lidlala indima ebalulekileyo kwinqwelomoya ekumgangatho ophantsi yoqoqosho efana ne-eVTOL, ngakumbi njengomaleko wesangweji yobusi bekhabhoni.
Kwintsimi yeenqwelo zemoya ezingabonakaliyo, izinto ze-honeycomb ze-Nomex (iphepha le-aramid) lisetyenziswa ngokubanzi, lisetyenziswe kwigobolondo ye-fuselage, isikhumba sephiko kunye nomgca ohamba phambili kunye nezinye iindawo.
Okunyeisangweji izinto ezidibeneyo
Iinqwelo-moya ezisezantsi, ezifana neenqwelo ezihamba emoyeni ezingenabantu, ngaphezu kokusebenzisa izinto eziqinisiweyo ezifana ne-carbon fiber, i-glass fiber kunye ne-aramid fiber kwinkqubo yokuvelisa, izinto ze-sandwich zesakhiwo ezifana ne-honeycomb, ifilimu, iplastiki ye-foam kunye ne-foam glue nazo zisetyenziswa ngokubanzi.
Ekukhethweni kwezinto zesandwich, ezisetyenziswa ngokuqhelekileyo ziyi-sandwich ye-honeycomb (efana ne-honeycomb yephepha, i-honeycomb ye-Nomex, njl.), i-sandwich yeplanga (efana ne-birch, i-paulownia, i-pine, i-basswood, njl.) kunye ne-foam sandwich (njenge-polyurethane, i-polyvinyl chloride, i-polystyrene foam, njl.).
Isakhiwo se-sandwich ye-foam sisetyenziswe ngokubanzi kwisakhiwo se-airframes ye-UAV ngenxa yeempawu zayo ezingenamanzi kunye neempawu ezijikelezayo kunye neenzuzo zobuchwepheshe zokukwazi ukuzalisa imingxunya yesakhiwo sangaphakathi sephiko kunye nephiko lomsila ngokubanzi.
Xa uyila ii-UAVs ezinesantya esiphantsi, izakhiwo zesangweji zobusi zidla ngokusetyenziselwa iinxalenye ezineemfuno zamandla aphantsi, iimilo eziqhelekileyo, iindawo ezinkulu ezigobileyo kwaye kulula ukuzibeka, njengeendawo zokuzinzisa iphiko langaphambili, imiphezulu yokuqina komsila, iphiko lokuzinzisa imiphezulu, njl njl. Izakhiwo zesandwich ze-foam zikhethwayo.Izakhiwo ze-sandwich ezifuna amandla aphezulu, izakhiwo zesandwich zokhuni zinokuthi zikhethwe.Kuzo ezo ndawo zifuna zombini amandla aphezulu kunye nokuqina okuphezulu, njengesikhumba se-fuselage, i-T-beam, i-L-beam, njl. ifayibha eyomeleziweyo, imathiriyeli ye-matrix, umxholo wefayibha kunye ne-laminate, kunye nokuyila ii-engile zokubeka ezahlukeneyo, iileya kunye nolandelelwano lwe-layer, kunye nokunyanga ngamaqondo okushisa ahlukeneyo kunye noxinzelelo loxinzelelo.
