Ua lilo nā mea hui i mea kūpono no ka hana ʻana i nā mokulele haʻahaʻa ma muli o ko lākou māmā, ikaika kiʻekiʻe, kūpaʻa i ka pala a me ka plasticity. I kēia au o ka hoʻokele waiwai haʻahaʻa e alualu ana i ka pono, ke ola pākaukau a me ka palekana o ke kaiapuni, ʻo ka hoʻohana ʻana i nā mea hui ʻaʻole wale e pili i ka hana a me ka palekana o nā mokulele, akā ʻo ia ke kī i ka hoʻolaha ʻana i ka hoʻomohala ʻana o ka ʻoihana holoʻokoʻa.
ʻO ke kaula kalaponamea i hui pū ʻia
Ma muli o kona māmā, ikaika kiʻekiʻe, kūpaʻa i ka palaho a me nā ʻano ʻē aʻe, ua lilo ka fiber kalapona i mea kūpono no ka hana ʻana i nā mokulele haʻahaʻa. ʻAʻole hiki ke hōʻemi wale i ke kaumaha o nā mokulele, akā hoʻomaikaʻi pū i ka hana a me nā pono waiwai, a lilo i mea pani kūpono no nā mea metala kuʻuna. ʻOi aku ma mua o 90% o nā mea i hui pū ʻia i loko o nā skycars he fiber kalapona, a ʻo ke koena ma kahi o 10% he fiber aniani. I loko o nā mokulele eVTOL, hoʻohana nui ʻia ka fiber kalapona i nā ʻāpana kūkulu a me nā ʻōnaehana propulsion, e helu ana ma kahi o 75-80%, ʻoiai nā noi kūloko e like me nā kaola a me nā hale noho no 12-14%, a ʻo nā ʻōnaehana pila a me nā lako avionics no 8-12%.
ʻO ke olonāmea i hui pū ʻia me ke aniani
ʻO ka palaki i hoʻoikaika ʻia e ka Fiberglass (GFRP), me kona kūpaʻa i ka pala, ke kūpaʻa wela kiʻekiʻe a me ka haʻahaʻa, ke kūpaʻa i ka radiation, ka pale ahi a me nā ʻano anti-aging, he kuleana koʻikoʻi ia i ka hana ʻana i nā mokulele haʻahaʻa e like me nā drones. ʻO ka hoʻohana ʻana i kēia mea e kōkua i ka hōʻemi ʻana i ke kaumaha o ka mokulele, hoʻonui i ka ukana, mālama i ka ikehu, a hoʻokō i kahi hoʻolālā waho nani. No laila, ua lilo ʻo GFRP i hoʻokahi o nā mea nui i ka hoʻokele waiwai haʻahaʻa.
I ke kaʻina hana o nā mokulele haʻahaʻa, hoʻohana nui ʻia ka lole fiberglass i ka hana ʻana i nā ʻāpana kūkulu koʻikoʻi e like me nā mokulele, nā ʻēheu, a me nā huelo. Kōkua kona mau ʻano māmā i ka hoʻomaikaʻi ʻana i ka pono holo o ka mokulele a hāʻawi i ka ikaika kūkulu ikaika a me ke kūpaʻa.
No nā ʻāpana e pono ai ka permeability nalu maikaʻi loa, e like me nā radomes a me nā fairings, hoʻohana pinepine ʻia nā mea composite fiberglass. No ka laʻana, hoʻohana ka UAV lōʻihi kiʻekiʻe a me ka uav RQ-4 "Global Hawk" o ka US Air Force i nā mea composite carbon fiber no ko lākou mau ʻēheu, huelo, ʻāpana mīkini a me ka fuselage hope, ʻoiai ʻo ka radome a me ka fairing i hana ʻia me nā mea composite fiberglass e hōʻoia i ka hoʻoili hōʻailona maopopo.
Hiki ke hoʻohana ʻia ka lole fiberglass e hana i nā fairings a me nā puka makani mokulele, ʻaʻole wale ia e hoʻonui i ke ʻano a me ka nani o ka mokulele, akā e hoʻonui pū i ka ʻoluʻolu o ka holo. Pēlā nō, i ka hoʻolālā ukali, hiki ke hoʻohana ʻia ka lole fiber aniani e kūkulu i ka ʻano o waho o nā panela solar a me nā antennas, no laila e hoʻomaikaʻi ana i ke ʻano a me ka hilinaʻi hana o nā ukali.
ʻO ke olonā ʻAramidamea i hui pū ʻia
ʻO ka mea kumu meli pepa aramid i hoʻolālā ʻia me ke ʻano hexagonal o kahi meli kūlohelohe bionic ua mahalo nui ʻia no kona ikaika kūikawā maikaʻi loa, ka paʻakikī kūikawā a me ke kūpaʻa o ke kūkulu ʻana. Eia kekahi, he maikaʻi nō hoʻi ka pale leo o kēia mea, ka pale wela a me nā waiwai pale ahi, a he haʻahaʻa loa ka uahi a me ka ʻawahia i hana ʻia i ka wā o ke kuni ʻana. ʻO kēia mau ʻano e hoʻolilo iā ia i wahi ma nā noi kiʻekiʻe o ka aerospace a me nā ʻano halihali wikiwiki.
ʻOiai ke kiʻekiʻe o ke kumukūʻai o ka mea kumu honeycomb pepa aramid, ua koho pinepine ʻia ʻo ia he mea māmā koʻikoʻi no nā lako kiʻekiʻe e like me nā mokulele, nā missiles, a me nā satelite, ʻoi aku hoʻi i ka hana ʻana i nā ʻāpana kūkulu e pono ai ka permeability nalu broadband a me ke kūpaʻa kiʻekiʻe.
Nā pono māmā
Ma ke ʻano he mea nui no ka hoʻolālā fuselage, he kuleana koʻikoʻi ka pepa aramid i nā mokulele hoʻokele waiwai nui e like me eVTOL, ʻoiai hoʻi ma ke ʻano he papa sandwich honeycomb fiber carbon fiber.
Ma ke kahua o nā kaʻa mokulele unmanned, hoʻohana nui ʻia ka mea hoʻopili meli Nomex (pepa aramid), hoʻohana ʻia ia i loko o ka pūpū fuselage, ka ʻili ʻēheu a me ke kaʻe alakaʻi a me nā ʻāpana ʻē aʻe.
ʻĒ aʻenā mea i hui pū ʻia no ka sanwika
ʻO nā mokulele haʻahaʻa, e like me nā kaʻa mokulele unmanned, me ka hoʻohana ʻana i nā mea i hoʻoikaika ʻia e like me ke kalapona fiber, ke aniani fiber a me ka aramid fiber i ke kaʻina hana hana, hoʻohana nui ʻia nā mea kūkulu sandwich e like me ka honeycomb, ka ʻoniʻoni, ka plastic foam a me ka foam glue.
I ke koho ʻana i nā mea hana sanwika, ʻo ka sanwika meli (e like me ka pepa honeycomb, Nomex honeycomb, a pēlā aku), ka sanwika lāʻau (e like me ka birch, paulownia, paina, basswood, a pēlā aku) a me ka sanwika huʻa (e like me ka polyurethane, polyvinyl chloride, polystyrene foam, a pēlā aku) ka mea maʻamau i hoʻohana ʻia.
Ua hoʻohana nui ʻia ke ʻano sandwich foam i loko o ke ʻano o nā mokulele UAV ma muli o kona ʻano pale wai a me ka lana ʻana a me nā pono ʻenehana o ka hiki ke hoʻopiha i nā lua o ke ʻano kūloko o ka ʻēheu a me ka ʻēheu huelo holoʻokoʻa.
I ka hoʻolālā ʻana i nā UAV wikiwiki haʻahaʻa, hoʻohana pinepine ʻia nā ʻano sandwich meli no nā ʻāpana me nā koi ikaika haʻahaʻa, nā ʻano maʻamau, nā ʻili piʻo nui a maʻalahi hoʻi e kau i waho, e like me nā ʻili hoʻopaʻa ʻēheu mua, nā ʻili hoʻopaʻa huelo kū pololei, nā ʻili hoʻopaʻa ʻēheu, a pēlā aku. No nā ʻāpana me nā ʻano paʻakikī a me nā ʻili piʻo liʻiliʻi, e like me nā ʻili elevator, nā ʻili hoe, nā ʻili hoe aileron, a pēlā aku, makemake ʻia nā ʻano sandwich huʻa. No nā ʻano sandwich e pono ai ka ikaika kiʻekiʻe, hiki ke koho ʻia nā ʻano sandwich lāʻau. No kēlā mau ʻāpana e pono ai ka ikaika kiʻekiʻe a me ka paʻakikī kiʻekiʻe, e like me ka ʻili fuselage, T-beam, L-beam, a pēlā aku, hoʻohana pinepine ʻia ka ʻano laminate. Pono ka hana ʻana o kēia mau ʻāpana i ka preforming, a e like me ke koi ʻana o ka paʻakikī i loko o ka mokulele, ka ikaika kūlou, ka paʻakikī torsional a me nā koi ikaika, koho i ka fiber i hoʻoikaika ʻia, ka mea matrix, ka ʻike fiber a me ka laminate, a hoʻolālā i nā kihi kau like ʻole, nā papa a me ke kaʻina layering, a hoʻōla ma o nā mahana hoʻomehana like ʻole a me nā kaomi pressurization.
