Txhua lub dav hlau stealth siv cov thev naus laus zis uas muaj cov duab tshwj xeeb fuselage, txheej txheej, cov ntaub ntawv, thiab lwm yam. Txhua qhov no tso cai rau lub dav hlau ua kom pom tsis tau rau cov yeeb ncuab radars. Txoj kev txhim kho ntawm thev naus laus zis tau pib thaum Tsov Rog Ntiaj Teb Zaum II thiab tau ua rau ntau dua tsib caug xyoo.

Yuav ua li cas kom ua tiav stealth

Kev sib xyaw ua ke ntawm txoj kev sib txawv yog siv los ua kom tiav cov stealth. Qhov no tiv thaiv radar tsis ntawm bouncing tawm ntawm lub dav hlau thiab rov qab mus rau qhov chaw tshaj tawm hluav taws xob. Txoj kev nyuaj tshaj plaws yog siv cov nyhuv txuas mus txuas ntxiv. Feem ntau qhov chaw nkaum dav hlau kheej kheej muaj puag ncig thiab muaj qhov txawv txav ntawm cov vojvoog. Yog li, kab teeb los ntawm radar diverge nyob rau hauv tag nrho cov lus qhia, thiab tsis mus rau lub teeb liab qhov chaw. Cov qauv tsim no tsis muaj txoj cai ces kaum.

Txhawm rau xam lub vojvoog ntawm curvature thiab scatter ntawm radar beams uas nws yuav muab thaum twg los tau nyob rau hauv qhov chaw peb-seem, qhov loj dua lub zog siv yog qhov yuav tsum tau ua.

Thawj lub dav hlau tsim los siv cov thev naus laus zis no yog B-2 pob foob pob. Kuj tseem muaj npe hu ua Flying Wing. Txij li thaum txoj kev loj hlob ntawm lub khoos phis tawj thiab software tsim tau nrawm dhau los ntawm 20 xyoo dhau los, cov qauv ntawm cov qauv tam sim no tuaj yeem xam nrog qhov tseeb raug. Nyob rau tib lub sijhawm, qhov kev zov me nyuam yuav siv mus rau hauv lub dav hlau lub tshav dav hlau ntawm qhov hloov chaw coefficient, tawm tswv yim zoo dua cov duab aerodynamic.

Sawtooth fab

Lub dav hlau khov kho yuav tsum muaj qhov chaw cab qis. Tus ntoo khaub lig-kis no muab kev pom pom tom qab qis. Xim tsev thiab cov ntaub ntawv raws li "W" tus qauv pab ua kom tiav cov nyhuv no. Cov ntsiab lus ntawm cov qauv duab no yog nyob hauv ntau qhov kev teeb tsa ntawm stealth aircraft.

Cav nozzles

Txo cov ntoo khaub lig sab ntawm cov nozzles kuj tseem ceeb heev. Cov teeb meem no suav daws los ntawm kev kub siab uas cuam tshuam rau qhov chaw. Ib qho ntawm txoj kev ua tau yog siv cov khoom siv ceramic. Lawv tuaj yeem yog cov nplooj ntawv teeb nruab rau hauv qhov chaw ntawm cov pa hluav taws xob tsis zoo, lossis cov khoom tsim ua hnyav uas tsim cov npoo tsis sib xws.

Dej cawv

Lub kaus mom hlau taub hau yog ib qho ntawm cov khoom tseem ceeb ntawm lub teeb liab radar. Cov nyhuv no yog txhim kho los ntawm sab hauv bulkheads thiab thav duab. Txoj kev daws teeb meem yog tsim qauv cockpit uas tuaj yeem ua raws tus qauv ntawm radar stealth. Daim iav yog li npog nrog zaj duab xis los tswj kev kub sab hauv. Cov khoom yuav tsum yog nruj heev. Cov qauv yuav tsum nqus 85 feem pua ntawm cov hluav taws xob thermal thiab cuam tshuam txhua lub teeb liab.

Xaus

Qhov yuav txo tau tsawg tsawg ntawm cov xaim hluav taws xob vim los ntawm cov pa hluav taws xob los ntawm lub tshuab thiab lwm qhov chaw ntawm lub dav hlau yuav tsum tau coj mus rau hauv tus qauv tsim. Txawm li cas los xij, tsis yog txhua lub dav hlau ua kom pom tsis meej rau radars. Txawm tias qhov zoo tshaj plaws aircraft yuav ntes nrog tsawg zaus radar.
