1. Isicelo ku-radome ye-radar yokuxhumana
I-radome iyisakhiwo esisebenzayo esihlanganisa ukusebenza kukagesi, amandla esakhiwo, ukuqina, ukuma kwe-aerodynamic kanye nezidingo ezikhethekile zokusebenza. Umsebenzi wayo oyinhloko ukuthuthukisa ukuma kwe-aerodynamic kwendiza, ukuvikela uhlelo lwe-antenna endaweni yangaphandle, nokwandisa lonke uhlelo. Impilo, ukuvikela ukunemba kobuso be-antenna kanye nendawo. Izinto zokukhiqiza zendabuko ngokuvamile amapuleti ensimbi namapuleti e-aluminium, anezinkinga eziningi, njengekhwalithi enkulu, ukumelana nokugqwala okuphansi, ubuchwepheshe bokucubungula okukodwa, kanye nokungakwazi ukwakha imikhiqizo enezimo eziyinkimbinkimbi kakhulu. Isicelo siye sabhekana nemikhawulo eminingi, futhi inani lezicelo liyehla. Njengezinto ezisebenza kahle kakhulu, izinto ze-FRP zingaqedwa ngokungeza ama-conductive fillers uma kudingeka i-conductivity. Amandla esakhiwo angaqedwa ngokuklama ama-stiffeners nokushintsha ubukhulu bendawo ngokwezidingo zamandla. Isimo singenziwa sibe yizimo ezahlukene ngokwezidingo, futhi simelana nokugqwala, silwa nokuguga, isisindo esincane, singaqedwa ngokubeka ngesandla, i-autoclave, i-RTM nezinye izinqubo ukuqinisekisa ukuthi i-radome ihlangabezana nezidingo zokusebenza kanye nokuphila kwenkonzo.
2. Isicelo ku-antenna yeselula yokuxhumana
Eminyakeni yamuva nje, intuthuko esheshayo yokuxhumana ngeselula iholele ekwandeni okukhulu kwenani lama-antenna eselula. Inani le-radome esetshenziswa njengengubo yokuvikela ama-antenna eselula nalo lenyuke kakhulu. Izinto ze-radome eselula kumele zibe nokuvuleka kwamagagasi, ukusebenza kwangaphandle kokulwa nokuguga, ukusebenza kokumelana nomoya, kanye nokuvumelana kwe-Batch, njll. Ngaphezu kwalokho, impilo yayo yesevisi kumele ibe yinde ngokwanele, ngaphandle kwalokho izoletha ukuphazamiseka okukhulu ekufakweni nasekugcinweni, futhi inyuse izindleko. I-radome eselula ekhiqizwa esikhathini esidlule isebenzisa kakhulu izinto ze-PVC, kodwa le nto ayimelani nokuguga, inokumelana okuncane komthwalo womoya, impilo yesevisi emfushane, kanye nokusetshenziswa okuncane kakhulu. Izinto zepulasitiki eziqiniswe ngefayibha yengilazi zinokuvuleka kwamagagasi okuhle, ikhono eliqinile lokulwa nokuguga ngaphandle, ukumelana nomoya okuhle, ukuvuleka okuhle kwe-batch okukhiqizwa inqubo yokukhiqiza i-pultrusion, kanye nokuphila kwesevisi kweminyaka engaphezu kwengu-20. Ihlangabezana ngokugcwele nezidingo zama-radome eselula. Ithathe indawo ye-PVC kancane kancane. Ipulasitiki isibe ukukhetha kokuqala kwama-radome eselula. Ama-radome aphathwayo eYurophu, e-United States nakwamanye amazwe avimbele ukusetshenziswa kwama-radome epulasitiki e-PVC, futhi wonke asebenzisa ama-radome epulasitiki aqiniswe ngefayibha yengilazi. Njengoba izidingo zezwe lami zithuthuka kakhulu ngezinto ze-radome eziphathwayo, ijubane lokwenza ama-radome aphathwayo enziwe ngezinto zepulasitiki eziqiniswe ngefayibha yengilazi esikhundleni sepulasitiki ye-PVC liyasheshiswa kakhulu.
3. Isicelo ku-antenna yokwamukela i-satellite
I-antenna yokwamukela isathelayithi iyithuluzi elibalulekile lesiteshi somhlaba sesathelayithi, ihlobene ngqo nekhwalithi yesignali yesathelayithi etholayo kanye nokuqina kwesistimu. Izidingo zezinto zama-antenna esathelayithi isisindo esincane, ukumelana nomoya okunamandla, ukulwa nokuguga, ukunemba okuphezulu, akukho ukuguquguquka, impilo yesevisi ende, ukumelana nokugqwala, kanye nezindawo ezikhanyayo eziklanywayo. Izinto zokukhiqiza zendabuko ngokuvamile amapuleti ensimbi namapuleti e-aluminium, enziwa ngobuchwepheshe bokunyathela. Ubukhulu ngokuvamile buncane, abumelani nokugqwala, futhi bunempilo yesevisi emfushane, ngokuvamile iminyaka emi-3 kuya kwemi-5 kuphela, futhi imikhawulo yokusetshenziswa kwayo iya ngokuya iba nkulu. Yamukela izinto ze-FRP futhi ikhiqizwa ngokuhambisana nenqubo yokubumba ye-SMC. Inokuqina kosayizi omuhle, isisindo esincane, ukulwa nokuguga, ukuhambisana okuhle kwebhetshi, ukumelana nomoya okunamandla, futhi ingaklanywa ngokwezidingo ezahlukene ukwandisa amandla. Impilo yesevisi ingaphezu kweminyaka engama-20. , Ingaklanywa ukubeka i-mesh yensimbi nezinye izinto ukuze kufezwe umsebenzi wokwamukela isathelayithi, futhi ihlangabezane ngokugcwele nezidingo zokusetshenziswa maqondana nokusebenza kanye nobuchwepheshe. Manje ama-antenna e-satellite e-SMC asesetshenziswe ngobuningi obukhulu, umphumela muhle kakhulu, ngaphandle akukho ukulungiswa, umphumela wokwamukela muhle, futhi amathuba okusebenzisa nawo muhle kakhulu.
4. Ukusetshenziswa ku-antenna yesitimela
Isitimela sesikhuphule isivinini okwesithupha. Isivinini sesitimela siyashesha futhi sishesha, futhi ukudluliswa kwesignali kumele kusheshe futhi kube nembambo. Ukudluliswa kwesignali kwenziwa nge-antenna, ngakho-ke ithonya le-radome ekudlulisweni kwesignali lihlobene ngqo nokudluliswa kolwazi. I-radome yama-antenna esitimela e-FRP ibilokhu isetshenziswa isikhathi eside. Ngaphezu kwalokho, iziteshi zokuxhumana eziphathwayo azikwazi ukusungulwa olwandle, ngakho-ke imishini yokuxhumana ephathwayo ayikwazi ukusetshenziswa. I-radome ye-antenna kumele imelane nokuguguleka kwesimo sezulu sasolwandle isikhathi eside. Izinto ezijwayelekile azikwazi ukuhlangabezana nezidingo. Izici zokusebenza ziboniswe ngezinga elikhulu okwamanje.
5. Ukusetshenziswa ku-core eqinisiwe yekhebula le-fiber optic
I-Aramid fiber reinforced fiber reinforced core (KFRP) uhlobo olusha lwe-non-metallic fiber reinforced core esebenza kahle kakhulu, esetshenziswa kabanzi kumanethiwekhi okufinyelela. Umkhiqizo unezici ezilandelayo:
1. Ilula futhi inamandla aphezulu: Ikhebula le-optical eliqiniswe ngefayibha ye-aramid linobukhulu obuphansi namandla aphezulu, futhi amandla alo noma i-modulus lidlula kakhulu elakhebula lensimbi nekhebula le-optical eliqiniswe ngefayibha yengilazi;
2. Ukwanda okuphansi: Ingqikithi eqinisiwe yekhebula le-optical eliqinisiwe le-aramid fiber ine-coefficient yokwanda eqondile ephansi kunentambo yensimbi kanye nengqikithi eqinisiwe yekhebula le-optical eliqinisiwe le-glass fiber ebangeni elibanzi lokushisa;
3. Ukumelana nokushayisana nokuphazamiseka: I-aramid fiber eqiniswe ngentambo ye-fiber optic ayigcini nje ngokuba namandla okushibilika aphezulu kakhulu (≥1700Mpa), kodwa futhi inomthelela ekumelaneni nokuphazamiseka kokuphazamiseka. Ngisho noma iphuka, isengagcina amandla okushibilika angaba ngu-1300Mpa ；
4. Ukuguquguquka okuhle: I-core yekhebula le-optical eliqiniswe ngefayibha ye-aramid inokwakheka okulula nokuthambile futhi kulula ukugoba, futhi ububanzi bayo obuncane bokugoba buphindwe izikhathi ezingu-24 kuphela kunobubanzi;
5. Ikhebula le-optical langaphakathi linesakhiwo esincane, ukubukeka okuhle, kanye nokusebenza okuhle kakhulu kokugoba, okufanelekela kakhulu ukuxhuma izintambo ezindaweni eziyinkimbinkimbi zangaphakathi.
