Zvishandiso zvemusanganiswa zvave zvinhu zvakanakira kugadzirwa kwendege yakaderera nekuda kwehuremu hwadzo, simba rakakwirira, kusagadzikana kwekuora uye plasticity.Munguva ino yehupfumi hwakaderera hunotevera kushanda zvakanaka, hupenyu hwebhatiri uye kuchengetedza kwezvakatipoteredza, kushandiswa kwezvinhu zvakaumbwa hazvikanganisi kuita uye kuchengetedzeka kwendege, asiwo kiyi yekusimudzira indasitiri yese.
Carbon fibercomposite zvinhu
Nekuda kwehuremu hwayo, simba rayo guru, kusagadzikana kwemarara uye humwe hunhu, kabhoni fiber yave chinhu chakanakira kugadzirwa kwendege yakadzika.Haingogone kuderedza huremu hwendege, asiwo kuvandudza mashandiro uye mabhenefiti ehupfumi, uye inova inotsiva inoshanda yezvigadzirwa zvesimbi zvechinyakare.More kupfuura 90% yezvinhu zvinoumbwa mu skycars icarbon fiber, uye yasara girazi rine fiber aircraft 10% mu eTO maumbirwo ezvikamu uye masisitimu ekufambisa, anoverengera anenge 75-80%, nepo mukati senge matanda uye zvigaro zvimiro zvinoverengera 12-14%, uye mabhatiri masisitimu uye avionics midziyo account ye8-12%.
Fibergirazi composite zvinhu
Fiberglass reinforced plastic (GFRP), ine corrosion resistance, yakakwirira uye yakaderera tembiricha kuramba, neradiation resistance, flame retardant uye anti-kuchembera hunhu, inoita basa rakakosha mukugadzirwa kwendege dzakaderera senge drones.Kushandiswa kwechinyorwa ichi kunobatsira kudzikisa huremu hwendege, kuwedzera mubhadharo, kuchengetedza simba, uye kuwana yakanaka, yakaderera yekunze dhizaini yeGFRP.
Mukugadzirwa kwendege yakaderera-yakadzika, jira refiberglass rinoshandiswa zvakanyanya mukugadzirwa kwezvinhu zvakakosha zvemukati senge airframes, mapapiro, uye miswe.Unhu hwayo husina huremu hunobatsira kuvandudza kugona kwekufamba kwendege uye kupa simba rakasimba rechimiro uye kugadzikana.
Kune zvikamu zvinoda kupenya kwakanakisa kwemafungu, senge radomes uye fairings, fiberglass composite zvinhu zvinowanzo shandiswa.Semuyenzaniso, yakakwirira-yakareba-yakareba UAV uye US Air Force's RQ-4 "Global Hawk" uav anoshandisa kabhoni faibha composite zvinhu pamapapiro adzo, muswe, imba yeinjini uye kumashure fuselage, ukuwo maratidziro efiber akaitwa kuti ave nechokwadi chekugadzirisa zvinhu uye magirazi efayibha akanyatsogadzirwa.
Fiberglass jira rinogona kushandiswa kugadzira ndege uye mahwindo, izvo hazvisi kungowedzera kutaridzika uye kunaka kwendege, asiwo kunowedzera kunyaradzwa kwekufamba.Saizvozvowo, mukugadzirwa kwesatellite, girazi rejira regirazi rinogona kushandiswawo kugadzira chimiro chekunze chekunze kwe solar panels uye antennas, nekudaro kuvandudza chitarisiko uye kuvimbika kwekushanda kwema satellite.
Aramid fibercomposite zvinhu
Iyo aramid paper honeycomb core material yakagadzirwa nehexagonal chimiro chebionic natural honeycomb inoremekedzwa zvikuru nekuda kwesimba rayo chairo, kuomarara kwaro uye kugadzikana kwechimiro.Pamusoro pezvo, chinyorwa ichi chinewo kunaka kwekuvharisa inzwi, kudzivirira kupisa uye kudzoreredza moto, uye utsi nehupfu hunogadzirwa panguva yekupisa hwakadzikira zvakanyanya. Aya maitiro anoita kuti itore nzvimbo munzvimbo yepamusoro-yekupedzisira yeaerospace uye yakakwirira-yekumhanya nzira dzekufambisa.
Kunyangwe mutengo wearamid bepa huchi core material wakakwira, inowanzo sarudzwa sekiyi isingaremi kumidziyo yepamusoro-soro senge ndege, zvombo zvinokandwa, uye masatelliti, kunyanya mukugadzira zvinhu zvakaumbwa zvinoda Broadband wave permeability uye kusimba kwakanyanya.
Mabhenefiti akareruka
Sechinhu chakakosha chefuselage chimiro, bepa re aramid rinoita basa rakakosha mundege huru yakaderera-yakakwirira yehupfumi seVTOL, kunyanya sekabhoni fiber huchi sandwich layer.
Mumunda wemotokari dzemuchadenga dzisina kurongeka, Nomex honeycomb material (aramid paper) inoshandiswawo zvakanyanya, inoshandiswa mufuselage shell, ganda remapapiro uye kumucheto uye zvimwe zvikamu.
Zvimwesandwich composite zvinhu
Ndege yakaderera-yakakwirira, yakadai semotokari dzemuchadenga dzisina kumira, kunze kwekushandisa zvakasimbiswa zvinhu zvakadai se carbon fiber, girazi fiber uye aramid fiber mukugadzira, sandwich zvimiro zvezvinhu zvakadai sehuchi, firimu, foam plastiki uye foam glue inoshandiswawo zvakanyanya.
Mukusarudzwa kwezvinhu zvesangweji, zvinowanzoshandiswa sandwich yehuchi (yakadai semapepa euchi, Nomex uchi, nezvimwewo), sandwich yehuni (yakadai sebirch, paulownia, pine, basswood, nezvimwewo) uye foam sandwich (yakadai se polyurethane, polyvinyl chloride, polystyrene foam, nezvimwewo).
Iyo foam sandwich chimiro chave chichishandiswa zvakanyanya muchimiro cheUAV airframes nekuda kwekusapinda kwemvura uye hunhu hunoyangarara uye zvakanakira tekinoroji yekukwanisa kuzadza mhango yemukati yemukati yebapiro nemuswe bapiro rose.
Paunenge uchigadzira yakaderera-speed UAVs, sandwich zvimiro zvehuchi zvinowanzo shandiswa kune zvikamu zvine simba rakaderera zvinodiwa, zvimiro zvenguva dzose, mahombe akakombama uye ari nyore kuisa kunze, senge pamberi pebapiro rekudzikamisa nzvimbo, vertical muswe unodzikamisa nzvimbo, mapapiro anodzikamisa nzvimbo, etc. Kune zvikamu zvine maumbirwo akaomarara uye madiki akakombama nzvimbo, senge referensi, rudder surface, etc. Foam sandwich structures inosarudzwa.Nekuda kwezvivako zve sandwich zvinoda simba rakakwirira, zvigadziro zve sandwich zvehuni zvinogona kusarudzwa.Kune izvo zvikamu zvinoda zvose simba rakakwirira uye kuoma kwepamusoro, zvakadai seganda refuselage, T-beam, L-beam, nezvimwewo, chimiro chelaminate chinowanzoshandiswa.Kugadzirwa kwezvikamu izvi kunoda preforming, uye maererano nezvinodiwa mu-ndege kuoma, kusimba kwakakodzera, kuoma kwesimba, kusimba kwekugadzirisa, kusimba uye kupfugama, yakasimbisa fiber, matrix zvinhu, fiber zvirimo uye laminate, uye dhizaini akasiyana ekuisa angles, akaturikidzana uye layering kutevedzana, uye kurapa kuburikidza nekudziya kwakasiyana tembiricha uye kudzvanywa kwekumanikidza.
