Xov tooj cua zaus (RF) thev naus laus zis siv hauv kev siv tub rog thiab kev lag luam avionics tseem ceeb txo qhov hnyav los txhim kho roj efficiency thaum ua tau raws li cov kev cai nruj hluav taws xob thiab kev nyab xeeb. Kev poob qis, theem kev ruaj ntseg, thiab kev ua haujlwm siab hauv kev poob siab thiab kev vibration ib puag ncig yuav tsum tau ua tib zoo soj ntsuam ntawm cov ntaub ntawv, qauv, thiab kev saib xyuas kom sib npaug downsizing.
Niaj hnub no cov kev xav tau ntawm ntau zaus - suav nrog 5G, tshiab thiab hloov kho satellite kev sib txuas lus (SATCOM), cov txheej txheem davhlau ya nyob twg (IFP) tshuab siv Bluetooth, thiab lwm yam - yog tsim kom muaj lub teeb yuag, me me, high-precision xov tooj cua zaus (RF)) Qhov kev thov rau kev daws teeb meem.
Qee zaum, cov tshuab no ua haujlwm ntawm zaus mus txog 90 GHz. Kev lag luam avionics xav tau kev poob qis, kub-tiv taus, thiab hloov tau yooj yim cables rau navigation, kev sib tsoo kom tsis txhob sib tsoo, thiab kev sib txuas lus hauv GPS, tsis siv neeg saib xyuas kev tshaj tawm xov xwm (ADS-B), satellite kev sib txuas lus, thiab huab cua-rau-hauv av. daim ntawv thov.
Qhov chaw rau kev siv avionics kuj txwv, vim tias lawv yuav tsum tau hloov mus rau ntau qhov kev thov hauv txhua lub cuab yeej. Raws li cov zaus nce thiab qhov sib cuam tshuam qhov loj me txo kom haum rau me me wavelengths, cov kev daws teeb meem semi-rigid ib txwm siv rau cov ntawv thov no. Txawm li cas los xij, cov khoom me me no ua rau tsis yooj yim, ua rau kev teeb tsa nyuaj thiab tsis tuaj yeem daws teeb meem.
Kev siv cov kev hloov pauv tau yooj yim, kev ua haujlwm siab ntawm cov cables tuaj yeem siv rau cov ntaub ntawv qhib cov thawv ntim ntom ntom ntom ntom; Cov khoom siv hloov tau yooj yim no tuaj yeem khoov ib ncig ntawm cov ces kaum nqaim thiab nyob ze rau qhov sib txuas kom txo tau qhov chaw ua hauj lwm, txuag chaw thiab Simplify cable routing nyob rau hauv qhov chaw nqaim. Cov kab hloov pauv tsis tas yuav tiv thaiv lub nraub qaum ntawm lub connector thiab ua kom yooj yim txij nkawm.
Hauv kev ya davhlau, kev vibration siab heev tuaj yeem ua rau lub zog ntawm lub rooj tsav xwm hluav taws xob. Interconnect systems yuav tsum txo qhov chaw ntawm cov cables thiab connectors kom tiv taus siab vibrations.
Kos kev tshoov siab los ntawm kev lag luam aerial innovation
Urban Air Transportation (UAM) yog ib lub tswv yim ntawm kev nyab xeeb thiab ua haujlwm tau zoo hauv huab cua uas yuav siv cov dav hlau uas siv tau los ua haujlwm thiab thauj cov neeg caij tsheb lossis cov khoom thauj hauv thaj chaw qis qis hauv nroog thiab hauv nroog. Feem ntau UAM tsheb yuav ua haujlwm qis dua 10,000 ko taw, thiab roj teeb lub zog txwv lawv qhov siab thiab kev ua siab ntev. Nrog rau kev txhim kho thev naus laus zis, qhov ceev ntawm UAMs hauv kev txav yuav nce ntxiv, thiab nyob rau hauv qhov xwm txheej hu ua "swarming", lawv cov kab ke ADS yuav tsum sib txuas lus tsis tu ncua kom tsis txhob muaj kev sib tsoo. Cov tshuab no vam khom rau cov kav hlau txais xov thiab cov khoom siv hluav taws xob ntau zaus los ua kom cov sensors sib txuas lus nrog ib leeg, yog li cov kab hluav taws xob qis, txhim khu kev qha, thiab lub teeb yuag yog qhov tseem ceeb rau kev sib txuas lus zoo.
Cov kev txhim kho ntxiv suav nrog cov kev daws teeb meem siab tshaj plaws hauv huab cua (AAM), uas yog raws li UAM lub tswv yim thiab nws cov ntawv thov yuav ua haujlwm sab nraum nroog ib puag ncig, los ntawm kev xa cov drones mus rau hluav taws xob ntsug nqa tawm thiab tsaws (eVTOL) daim ntawv thov. Zoo li lub tsheb hluav taws xob, eVTOL tswj cov cuab yeej khiav ntawm lub zog ntawm lub nkoj thiab lub roj teeb hnyav, yog li qhov hnyav yog qhov tseem ceeb. Yog li ntawd, cov thev naus laus zis no xav tau cov kev daws teeb meem siab tshaj plaws kom tau raws li cov kev xav tau tshiab, thaum ua raws li qhov loj thiab qhov hnyav uas tau ua rau lawv cov thawj coj tau ntau xyoo lawm.
UAS avionics
Lwm qhov kev loj hlob sai ntawm avionics yog lub tsheb tsis muaj neeg tsav dav hlau (UAV). Qee cov drones yog qhov yooj yim thiab siv tib cov ntaub ntawv txuas, uas yuav tsum muaj kev sib txuas lus RF yooj yooj yim. Txawm li cas los xij, nrog rau kev qhia txog kev siv tshuab thev naus laus zis, qee qhov ntawm cov drones no muaj qhov nrawm nrawm li Mach 5, uas ua rau cov kev xav tau rau qhov kub thiab txias. Qhov siab dua qhov siab, qhov siab dua, qhov siab dua qhov zaus, thiab qhov teeb meem nyuaj dua los ntawm cov khoom siv ntawm qhov pom. Cov teeb meem no tuaj yeem daws tau los ntawm dielectrics; Tsis tas li ntawd, nws tseem tuaj yeem siv cov ntaub ntawv quartz ua dielectrics rau kev siv hypersonic.
Thaum kawg, tus neeg tsim qauv yuav tsum nkag siab txog ib puag ncig, qhov siab xav tau ntawm drone, xav tau lub neej ntev npaum li cas, kev saib xyuas ntau npaum li cas, thiab qhov ntsuas qhov chaw twg muaj. Piv txwv li, yuav drones nqa hluav taws xob ua tsov rog (EW) cov tshuab lossis hluav taws xob txawj ntse, lossis puas yuav them cov ntaub ntawv txuas thiab yees duab?
Kho kev sib txuas
Ib qho kev txiav txim siab tseem ceeb rau kev sib txuas ntawm RF ntawm avionics yog lub dielectric thiab nws coj li cas hauv ib puag ncig thaum nws mus txog qhov sib npaug nrog ib puag ncig ib puag ncig. Piv txwv li, ntawm qhov chaw ya dav hlau, lub dav hlau yuav tsim ntau lub tshuab nqus tsev ib puag ncig los muab cov kev mob degassing rau dielectrics thiab lwm yam khoom siv hluav taws xob. Thaum lub dav hlau rov qab los rau hauv av, lub cable yog lub hauv paus nqus. Txhua yam kua los yog roj nyob ib ncig ntawm nws yuav raug absorbed los ntawm dielectric, thiab lawv yuav condense dua nyob rau hauv nws. Tom qab ntawd, dielectrics zoo li daim txhuam cev: tib txoj hauv kev kom tshem tawm cov kab mob yog ci rau lawv. Qhov no yog pom tseeb tsis muaj peev xwm nyob rau hauv lub dav hlau, yog li chav sealing kuj tseem ceeb rau high-end, high-performance, high-altitude applications.
Muaj ntau yam tseem ceeb uas yuav tsum tau xav txog thaum tsim cov kev daws teeb meem RF sib cuam tshuam. Piv txwv li, polyethylene txhim kho nplaim taws thiab nplaim taws; rau qhov chaw sab nraum zoov lossis sab hauv tsev, nws yog qhov kev xaiv zoo heev nrog cov nplaim hluav taws-retardant UL ntawv pov thawj sheath. Lus Cim: Polyurethanes tuaj yeem hloov tau yooj yim dua, tab sis lawv tsis tuaj yeem siv rau hauv ib puag ncig manned.
Nyob rau hauv cov nqe lus ntawm airframe, high-temperature resistant PTFE (synthetic fluoropolymer) dielectric cables feem ntau yog siv, thiab tuaj yeem ua ke nrog PTMP (polyester yas) daim kab xev winding nrog tsawg heev poob siab tshaj tus qauv. Hom kev daws teeb meem no tuaj yeem siv txog li 50 GHz lossis siab dua. Ntawm qhov kawg ntawm qhov kub thiab txias, qee cov silica cables raug ntsuas siab li 800 ° C lossis siab dua.
Connector optimization
Lub hom phiaj ntawm qhov kawg yog txhawm rau txhim kho cov neeg kho tshuab, ib puag ncig thiab hluav taws xob kev ua haujlwm ntawm cov khoom sib txuas thiab ua kom nws yooj yim heev rau nruab. Muaj ntau yam ntawm aluminium thiab yas connectors xaiv los ua kom lub teeb nyhav.
Kev lag luam yog siv Delrin thiab lwm yam khoom siv los tsim cov yas, suav nrog cov xov txuas, cov khoom sib txuas, thiab cov khoom siv bayonet. Lwm qhov kev tshawb fawb thiab kev txhim kho cov kev daws teeb meem ultralight tab tom ua, suav nrog cov kev daws teeb meem sib txuas nrog cov yas coupling thiab cov cuab yeej daws teeb meem. Txoj kev no yuav pab txhawb kev txij nkawm thiab pab kom cov neeg siv daws teeb meem ncaj qha rau ntawm qhov chaw.
Cov cuab yeej tuaj yeem yooj yim sib dhos
Thaum koj xav tau nruab RF interconnect kev daws teeb meem hauv kev lag luam tom qab lossis ua haujlwm txij nkawm ntawm qhov chaw, koj tuaj yeem siv cov cuab yeej es tsis txhob siv cov hniav ntawm qhov chaw, ua rau kev sib dhos ntawm qhov chaw muaj kev nyab xeeb thiab yooj yim dua hauv cov cheeb tsam uas muaj kev sib cav.
Txoj hauv kev no ntawm cov tuam txhab xws li Times Microwave Systems tso cai rau txhua tus siv tib lub cuab yeej ntawm lub cable rau tib daim ntawv thov, tsis yog ntau tus kws tshaj lij siv ntau hom cuab yeej thiab cov tswv yim.
Times Microwave Systems muaj InstaBend (IB) 047, uas yog lub compact, theem ruaj khov, hloov tau yooj yim me me coaxial cable. Qhov kev ua tau zoo tshaj plaws no yog Ameslikas tsim los rau kev siv davhlau ya nyob twg thiab tuaj yeem hloov kho tau yooj yim rau cov ntawv ntim ntim ntim ntim.
