Los ntawm kev rau txim rau Russia thiab txwv tsis pub muab cov thev naus laus zis thev naus laus zis rau peb lub tebchaws, Tebchaws Meskas vam tias yuav ua rau peb tsis muaj zog, rhuav tshem kev lag luam thiab tiv thaiv kev tsim cov cuab yeej ua tub rog siab heev. Lawv hais tias peb ua tsis tau yog tsis muaj American technology! Tab sis, qhov tseeb, ntawm qhov tsis sib xws, Asmeskas tshuav ntau ntawm nws qhov kev ua tau zoo tshaj plaws, suav nrog hauv kev ua tub rog, rau Russia.

Nov yog qhov piv txwv tsis ntev los no. Raws li lwm hnub hauv kev xam phaj nrog TASS, Honored Tub Rog Tsav Tsheb ntawm Lavxias Federation, Major General Vladimir Popov, ib feem ntawm kev txhim kho los ntawm Soviet aircraft ntawm ntsug (luv luv) take-off thiab tsaws unclaimed los ntawm Russia Yog-141tau siv nyob rau hauv lub creation ntawm lub thib tsib tiam American stealth fighter Lockheed Martin F-35B Lightning II.

Nws tau hais tias "Kuv tsis tuaj yeem sau cov npe tam sim no, lawv yog tus tsim qauv, tus thawj coj ntawm cov lus qhia," nws hais. - Tom qab ntawd peb tau ntsib, kuv yuav tsum tau sib tham nrog lawv, lawv yws yws heev tias qhov tsis muaj qhov xav tau tshwm sim vim qhov tshwm sim ntawm ntau yam teeb meem nyiaj txiag. Kev txiav txim siab nom tswv tsis tuaj yeem ua tau, thiab qhov ntawd yog qhov tseem ceeb tshaj plaws. Muaj cov dav hlau, cov haujlwm muaj nyob, tsuas yog pab pawg xav tau, "tus kws tshaj lij tau hais.

Raws li nws, "rau nyiaj peb cov kws tshaj lij tawm mus thiab ua haujlwm nyob ntawd". "Tom qab tag nrho, cov no twb yog peb cov neeg koom tes, thiab tsis yog yeeb ncuab lossis yeeb ncuab," tus kws tsav dav hlau sau tseg. Raws li nws, "Yog li ntawd, qhov tseeb, ib feem ntawm kev txhim kho mus rau ntawd." "Thiab peb pom lawv hnub no, los ntawm txoj kev, hauv qhov project F-35. Koj pom tias nws hloov tau li cas: ob qho tib si hauv av (luv tawm thiab tsaws) thiab hauv hiav txwv (nce nqa tawm thiab tsaws). Yuav luag txhua yam ua haujlwm rau lawv. Txawm nyob rau hauv configuration, lawv zoo sib xws (American thiab Lavxias teb sab aircraft - V. M.) me ntsis: tus Tsov tus tw seem, tswj cheeb tsam ntawm lub nozzle systems. Muaj ib yam zoo li no, nws raug ntes tau, "tus Thawj Tub Ceev Xwm hais. Nyob rau tib lub sijhawm, nws hais ntxiv tias pem hauv ntej ntawm lub dav hlau thiab lub teeb ntawm F-35B Lightning II yog qhov sib txawv, vim yog kev siv tshuab stealth. Popov hais tias "Tab sis peb tsis muaj txoj haujlwm zoo li no thaum xub thawj.

Tus kws tsav dav hlau tau sau tseg tias Russia tiag tiag xav tau txoj haujlwm ntsug (luv luv) tshem tawm thiab tsaws tsaws, vim tias cov no yog "cov txheej txheem ntuj" uas yog "hais los ntawm kev ua haujlwm thiab kev ua haujlwm zoo." Thaum Lub Yim Hli, Tus Lwm Thawj Fwm Tsav Tebchaws Yuri Borisov tau tshaj tawm tias Ministry of Defense tau pib tsim lub dav hlau tshiab nrog kev tawm mus thiab tsaws. Hauv 1991-1997 (raws li lwm qhov chaw - 1995-1997), thaum Lockheed Martin (lossis txog 1995 - tsuas yog Lockheed) thiab Yakovlev Design Bureau, tus tsim tawm ntawm Yak-141, koom tes ua haujlwm, Asmeskas tuam txhab tau txais kev nkag mus rau kev tshaj lij. cov ntaub ntawv thiab cov qauv Yak-141, sau Task & Purpose magazine nyob rau lub Plaub Hlis.

Yog li, lub dav hlau tshiab tshaj plaws hauv Asmeskas tau tsim ua tsaug rau Lavxias technology. Alas, qhov no tshwm sim nyob rau hauv cov ntsiab lus ntawm lub cev qhuav dej ntawm lub USSR nyob rau hauv lub 90s, ib tug ntse txo nyob rau hauv cov nyiaj txiag kev loj hlob ntawm science thiab tub rog, raws li zoo raws li peb naive ntseeg hais tias cov tub rog confrontation twb tas, thiab lub tebchaws United States tsis yog ib tug yeeb ncuab. rau peb, tab sis yog "tus khub".

Lavxias teb sab technology "stealth"

Thiab muaj ntau yam piv txwv ntawm Teb Chaws Asmeskas qiv peb cov thev naus laus zis siab. Nyob rau xyoo 1970, cov neeg Amelikas tau tsim lub npe hu ua "tsis pom lub dav hlau" SR-71, tsim los ntawm kev siv tshuab stealth, hais tias lawv yog "kev ua tau zoo tshaj plaws." Txawm li cas los xij, tom qab ntawd nws tau paub tias qhov no tau ua tiav los ntawm kev tshawb pom ntawm Soviet physicist Petra Ufimtseva.

Xyoo 1966, tus kws tshaj lij Asmeskas radar ua haujlwm ntawm Lockheed cog tau hla ib tsab xov xwm los ntawm P. Ufimtseva nyob rau hauv lub npe nrov Soviet scientific thiab technical journal. Tsab ntawv hais tias cov dav hlau ntawm ib hom, ua los ntawm tej yam khoom, faceted thiab pleev xim rau hauv ib txoj kev, yog xyaum tsis pom radars. Cov ntawv no yog qhov txaus siab rau Asmeskas cov tub rog tshwj xeeb, thiab hauv Tebchaws Meskas, siv peb qhov kev tshawb nrhiav, lawv tau txiav txim siab los tsim thiab sim cov dav hlau zoo li no.

Yog li ntawd, nyob rau hauv thaum ntxov 1990s, lub tebchaws United States tsim lub F-117 fighter-bomber thiab B-2 hnyav lub tswv yim bomber. Los ntawm txoj kev, nws tus kheej tau koom nrog hauv kev tsim cov tom kawg. Peter Ufimtsev … Thaum nyob rau xyoo 1980, kev ua haujlwm ntawm Soviet "stealth" ntawm Ufimtsev lub tswv yim raug tso tseg nyob rau hauv Russia, tus tsim tawm tsam tau tsiv mus rau Tebchaws Meskas …

Txawm li cas los xij, muaj ib qho version uas cov thev naus laus zis no tau cog rau ntawm cov neeg Asmeskas txhob txwm tshaj tawm, txij li nws tau sim hauv USSR thiab txiav txim siab tso tseg. Yam tsawg kawg yog ob lub tuam tsev tsim qauv hauv Soviet tau tsim thiab sim ntau yam ntawm stealth aircraft. Cov kev cai lij choj tau txiav txim siab tsis pom zoo rau "tsis pom" thev naus laus zis.

Tsis muaj leej twg. Chasing invisibility

Ua ntej, lub stealth aircraft, ua raws li lub tswv yim ntawm Ufimtsev, vim hais tias ntawm nws cov duab muaj tsawg ceev thiab maneuverability, nws yog tsis zoo yoog mus rau combat maneuver.

Thib ob, lub dav hlau tuaj yeem kuaj pom qhov muag thiab nrog tshwj xeeb high-frequency radars. Tsis tas li ntawd, thaum lub foob pob tawg tau qhib thiab hauv qee hom kev ya davhlau, nws pom tau nrog cov pa radars thiab, tom qab "serif", tuaj yeem tua tau yooj yim.

Cov kws tshaj lij tiv thaiv huab cua hauv Serbian tau kwv yees qhov no rov qab rau xyoo 1999, thaum Soviet tsim Yugoslav MiG-29 tua tus neeg Asmeskas F-117A saum ntuj ceeb tsheej hla Belgrade. Niaj hnub no, cov kws paub txog kev tiv thaiv taw qhia tias txawm tias kim F-35 stealth aircraft tsis yog "ceeb toom" rau Suav thiab Lavxias radars.

Thib peb, tus nqi ntawm xws aircraft yog siab heev. B-2 bomber nqi 1.157 billion … nyiaj daus las yog lub dav hlau kim tshaj plaws hauv keeb kwm ntawm aviation. Yog li, tau qiv lub tswv yim ntawm Soviet engineers los ntawm USSR, cov neeg Amelikas "tau mus rau hauv lub pas dej." Txawm li cas los xij, qhov tseeb ntawm qhov no qhia tau hais tias hauv Tebchaws Meskas lawv tsis ua lawv tus kheej ntau, tab sis qiv cov khoom tsim los ntawm peb.

Davhlau mus rau lub hli raws "Kondratyuk khiav"

Nws paub tias txawm tias nws txoj haujlwm tseem ceeb tshaj plaws "Apollo" - kev sib tw thiab tsaws ntawm lub hli - Tebchaws Asmeskas tau siv cov tswv yim ntawm cov kws ua haujlwm Lavxias. Yuri Kondratyuk … Nws lub npe tiag tiag Alexander Shargey, uas nws, ib tug tsarist tub ceev xwm, raug yuam kom hloov tom qab lub kiv puag ncig, thiab ces ploj mus thaum lub Great Patriotic ua tsov ua rog.

Txawm nyob hauv tsev kawm ntawv ntawm tub ceev xwm, Shargei pib sau ntawv "Rau tus neeg uas yuav nyeem ntawv txhawm rau tsim" … Nyob rau hauv nws, ntawm nws tus kheej ntawm Konstantin Tsiolkovsky, nws muab tau qhov sib npaug ntawm cov dav hlau propulsion los ntawm nws txoj kev, muab ib daim duab ntawm plaub-theem foob pob ua ntxaij khiav ntawm oxygen-hydrogen roj, roj oxidizer, lub tshuab foob pob hluav taws electrostatic, thiab ntau ntxiv.

Raws nraim Shargey yog thawj zaug los tawm tswv yim txog kev siv atmospheric tsis kam mus decelerate lub foob pob ua ntxaij thaum lub sij hawm qhovntsej thiaj tsis mob, kev siv lub hnub ci zog rau lub hwj chim onboard systems ntawm spacecraft. Nws tau los nrog lub tswv yim, thaum ya mus rau lwm lub ntiaj teb, kom tso lub nkoj mus rau hauv lub orbit ntawm ib qho khoom siv satellite. Thiab xa ib tug neeg mus rau lawv thiab rov qab mus rau lub ntiaj teb, siv lub "shuttle", ib tug me me nqa-off thiab tsaws nkoj. Cov phau ntawv muaj xws li lub npe hu ua "Kondratyuk khiav" - lub davhlau trajectory ntawm ib tug spacecraft nrog ib tug rov qab mus rau lub ntiaj teb.

Thaum ib qho ntawm nws mus rau lub peev, tus engineer ntsib nrog Sergey Korolev, leej twg yog tus thawj coj Pab Pawg rau Kev Kawm ntawm Dav Hlau Propulsion - GIRD, thiab nws tau hais tias nws mus ua haujlwm rau nws. Tab sis Shargei-Kondratyuk tsis kam. Tom qab nyeem cov lus nug ntawm daim ntawv nug, uas yuav tsum tau ua kom tiav rau kev nkag mus rau GIRD, yav dhau los Tus Saib Xyuas Dawb tau nkag siab: tom qab kuaj xyuas tag nrho cov ntaub ntawv los ntawm NKVD, nws raug hem nrog kev raug thiab tua.

"Peb pom ib phau ntawv me me uas tsis pom zoo luam tawm hauv Russia tam sim ntawd tom qab kev hloov pauv," nws tau lees paub. Dr. Lowe, koom nrog hauv "Lunar Program" NASA, tom qab nws ua tiav. - Nws tus sau, Yuri Kondratyuk, substantiated thiab xam lub zog profitability ntawm tsaws rau lub hli raws li lub tswv yim: ya mus rau lub hli lub orbit - xa mus rau lub hli los ntawm orbit - rov qab mus rau orbit thiab docking nrog lub ntsiab nkoj - rov qab mus rau lub ntiaj teb."

Nws hloov tawm, zoo li qhov no, tsis ncaj ncees lawm, nws tau lees paub tias lub davhlau ntawm Asmeskas cov neeg caij nkoj mus rau lub hli tau ua raws "Kondratyuk txoj kev".

Txawm ntau convincing nyob rau hauv kev paub txog qhov zoo ntawm tus kws tshawb fawb Lavxias teb sab yog qhov txawv txav ntawm "thawj txiv neej nyob rau lub hli", astronaut Neil Armstrong. Tom qab nws lub dav hlau nto moo, cov neeg Amelikas tau mus xyuas Novosibirsk, qhov chaw uas nws tau sau ib pob ntawm lub ntiaj teb nyob ze lub tsev uas Kondratyuk-Shargey nyob thiab ua haujlwm, coj nws mus rau Tebchaws Meskas thiab nchuav tawm ntawm Cape Canaveral - qhov chaw uas lub foob pob hluav taws tau tawm mus rau lub hli. …

Leej twg tsim American aviation

Tab sis peb "pab" cov neeg Amelikas tsis yog tsuas yog hauv kev ya mus rau lub hli thiab foob pob hluav taws. Lavxias teb sab txuj ci yeej tsim American aviation. Txhua leej txhua tus paub hnub no Igor Sikorsky, ib tug kawm tiav ntawm lub koom haum St. Petersburg Polytechnic, uas tau tsim lub ntiaj teb thawj lub nyoob hoom qav taub hauv Tebchaws Meskas. Lub nyoob hoom qav taub, uas cov thawj tswj hwm ntawm Tebchaws Meskas tseem ya, tseem hais tias "Sikorsky".

Tab sis kuj tseem muaj peb lwm cov neeg txheeb ze - Mikhail Strukov, Alexander Kartveli, Alexander Prokofiev-Seversky, leej twg ua tau tsim cov tub rog Asmeskas. Tau ntau xyoo lawv raug suav hais tias yog peb "cov neeg tawg rog dawb", "cov neeg tawg rog", "cov neeg ntxeev siab", thiab yog li ntawd me ntsis tsis paub txog cov txuj ci tseem ceeb hauv peb lub tebchaws tau ntev.

Ib zaug nyob rau teb chaws USA, Seversky tsim lub tuam txhab tsim dav hlau Seversky Aircraft Corporation. Nws cov khoom tseem ceeb yog SEV-3 amphibious aircraft tsim los ntawm nws, uas qhia tau hais tias zoo heev davhlau zoo. Nyob rau hauv lub dav hlau no, Seversky teem ib lub ntiaj teb ceev cov ntaub ntawv rau amphibians - 290 kilometers ib teev, rau ntau xyoo tsis muaj leej twg yuav yeej qhov kev ua tau zoo.

Thaum US Air Force tshaj tawm kev sib tw los hloov Boeing 26 fighter, Severskiy lub tuam txhab xa P-35 fighter rau nws thiab tau txais ib tug tsoom fwv txiav txim rau 77 lub dav hlau, dhau los ua ib tug loj tshaj plaws aircraft tsim tuam txhab uas muag nyob rau hauv lub tebchaws United States. Tom qab ntawd nws tsim ib tug xov tooj ntawm zoo aircraft qauv, qhia ntau inventions.

Lwm tus tsim ntawm Asmeskas tub rog aviation, Mikhail Strukov, yug nyob rau hauv Yekaterinoslav rau hauv ib tsev neeg noble. Strukov tsis lees txais lub kiv puag ncig, thiab tsis ntev nws pom nws tus kheej hauv lub luag haujlwm ntawm cov neeg tsiv teb tsaws chaw hauv New York. Hauv Tebchaws Meskas, nws tau tswj hwm nws txoj kev kawm tiav hauv civil engineering ntawm Columbia University thiab pib ua haujlwm hauv nws txoj haujlwm tshwj xeeb, nws tsis ntev los no tsim nws lub tuam txhab.

Thaum tsov rog pib, Strukov tswj kom tau ib qho kev txiav txim los ntawm aviation hais kom ua rau kev tsim kho ntawm gliders thauj. Qhov no yog li cas Chase Aircraft Company tau yug los. Strukov tau los ua nws tus thawj tswj hwm thiab tus tsim qauv, thiab lwm tus neeg tsiv teb tsaws chaw los ntawm Russia los ua nws tus thawj coj. M. Gregor(Grigorashvili).

Tom qab Tsov Rog Ntiaj Teb Zaum II, Strukov tsim lub dav hlau thauj S-123 … Tom qab ntawd npaj lub tuam txhab "Strukov Aircraft Corporation", nws tsim lub zus tau tej cov aircraft nyob rau hauv lub npe "Tus muab" - "Tswj Vaj Huam Sib Luag", uas tau txais koob meej tshwj xeeb thaum Tsov Rog Nyab Laj rau lawv txoj kev muaj sia nyob thiab kev ntseeg siab, dhau los ua ib qho ntawm "cov neeg ua haujlwm" ntawm American Air Force. Ntau pua ntawm cov tshuab no tau tsim nyob rau hauv Tebchaws Meskas, tom qab ntawd tau siv hauv Thaib teb, Cambodia, thiab Kaus Lim Qab Teb.

Thaum Tsov Rog Thoob Ntiaj Teb thib 1 Alexander Kartveli ua hauj lwm nyob rau hauv lub Lavxias teb sab tub rog raws li ib tug artillery tub ceev xwm. Kuv tau paub txog aviation nkaus xwb nyob rau pem hauv ntej thiab thiaj li nqa tawm los ntawm kev ya davhlau uas kuv txiav txim siab muab kuv lub neej tag nrho rau kev lag luam no. Nws raug xa mus rau Paris los txhim kho nws txoj kev kawm dav hlau, qhov chaw nws nkag mus rau Tsev Kawm Qib Siab Aviation. Tab sis los ntawm Russia, qhov twg "Liab ntshai" raged, tu siab xov xwm tuaj. Raws li yav dhau los tus tub ceev xwm tsarist, nws pib ntshai rau nws lub neej, thiab thaum nws paub tias Bolsheviks tau tuav lub hwj chim, Kartveli txiav txim siab tsis rov qab los …

Hauv Tebchaws Meskas, Kartveli tau raug tsa los ua tus thawj coj ntawm lub chaw tsim khoom, qhov chaw muaj zog tua dav hlau ntawm Tsov Rog Ntiaj Teb Zaum Ob "Republic P-47 Thunderbolt" tau tsim. Txog thaum kawg ntawm kev tsov rog, ntau dua 15 txhiab xws li cov dav hlau, thaum theem ntawm kev poob lawv tau qis dua li lwm lub dav hlau Asmeskas.

Tom qab ntawd Kartveli bureau tsim ib qho ntawm thawj American jet fighters. F-84Thunderjet. Nws tau siv thaum lub sij hawm Tsov Rog Kauslim, tab sis thaum Soviet MiG-15s tshwm sim nyob rau sab qaum teb Kauslim, Kartveli tau hloov kho sai ntawm nws lub dav hlau, thiab nws qhov ceev tau nce mus rau 1150 kilometers ib teev. Qhov kawg fighter tsim los ntawm Kartveli yog supersonic F-105, uas tau siv dav los ntawm Asmeskas thaum Tsov Rog Nyab Laj.

Kartveli, raws li tus tsim qauv dav hlau, tau txais kev lees paub thoob ntiaj teb, tau los ua tus tswv cuab ntawm National Aeronautical Association, tau txais tus kws kho mob tshwj xeeb. Ntxiv nrog rau cov neeg tua rog, nws kuj tau tsim lub dav hlau amphibious, plaub-engined yees duab reconnaissance aircraft nrog dav dav dav dav.

qiv thiab nyiag

Tab sis tsis tsuas yog nyob rau hauv aviation thiab astronautics, Lavxias teb sab inventions tau siv nyob rau hauv lub tebchaws United States. Nws yog lub npe hu hais tias ib tug ntawm cov tseem ceeb inventions ntawm lub xyoo pua nees nkaum - lub TV tsim nyob rau hauv Teb Chaws Asmeskas los ntawm ib tug neeg ua haujlwm Lavxias Vladimir Zvorykin: 3 Lab tus kiv cua tos koj rau Webtalk!.

Thiab lwm yam txuj ci tseem ceeb ntawm technology - yees duab recorder invented nyob rau hauv American av los ntawm ib tug Lavxias teb sab engineer Alexander Ponyatov.

Thiab ua tsaug rau high-octane roj av - lub invention ntawm ib tug Lavxias teb sab emigrant chemist Vladimir Ipatiev - Cov dav hlau Asmeskas tau ya nrawm dua li German thaum Tsov Rog Ntiaj Teb Zaum II.

Nyob rau nruab nrab-1980s, ib tug xibfwb hluas Felix Beloyartsev pib tsim cov tshuaj uas tsis tau pom dua los uas tuaj yeem hloov ntshav plasma. Lub cim ntshav hloov tau lub npe "Perftoran" … Cov tshuaj tau pib tsim nyob rau hauv 2016 nkaus xwb, tab sis nws cov yam ntxwv tseem ceeb tshaj cov khoom lag luam uas tau tshwm sim tom qab. Cov neeg Amelikas tau tuav cov mis ntawm Soviet cov ntshav hloov 30 xyoo dhau los thiab tau pib siv Perftoran hauv lawv cov kev xyaum, hinting tias nws yog lawv uas tsim cov ntshav plasma.

Peb muaj neeg Amelikas coob heev tsuas yog nyiag … Yog li ntawd, nyob rau hauv thaum ntxov 1990s, ib tug loj npaum li cas ntawm cov ntaub ntawv hais txog lub zais cia Soviet kev loj hlob, tshwj xeeb tshaj yog nyob rau hauv lub chaw lag luam, pib ntws mus rau lub tebchaws United States los ntawm ntau yam raws.

Ntau tus ntseeg tias ua tsaug rau cov xau no, cov neeg Asmeskas nyiag lub tswv yim ntawm lub nkoj orbital. Ob qhov kev tshwm sim ntawm Npau Suav Chaser thiab cov kev daws teeb meem zoo ib yam li qhov project tsim hauv USSR rov qab rau xyoo 60s. Tus thawj yog lub Soviet orbital foob pob ua ntxaij dav hlau "BOR". Txawm li cas los xij, qhov no tsis yog tib qho uas lub Xeev "qiv" los ntawm peb hauv kev lag luam no.

Nyob rau hauv thaum ntxov 90s, ib tug delegation ntawm lub tebchaws United States tuaj txog ntawm ib tug Lavxias teb sab cog qhov twg ejection rooj rau tub rog pilots "K-36 DM". Cov rooj zaum zoo sib xws tau tsim nyob rau hauv USSR rov qab rau xyoo 70s. Cov neeg Amelikas tau yuav ib pawg me me ntawm cov qauv tsim tshwj xeeb no thiab sai sai tau pib tsim "lawv tus kheej", zoo li ob lub peas hauv lub plhaub taum zoo ib yam li peb. Tom qab ntawd hauv peb lub tebchaws muaj lub sijhawm nyuaj, yog li tsis muaj leej twg rov saib xyuas kom tau txais patent. Cov neeg Amelikas tsis tau them ib lub dime rau lub tshuab nyiag khoom.

Los ntawm txoj kev, txawm tus thawj nyob rau hauv lub ntiaj teb no Tus Kheej Computer tau tsim tsis yog los ntawm Asmeskas tuam txhab Apple Computers thiab tsis yog xyoo 1975, tab sis hauv USSR hauv 1968 Soviet designer los ntawm Omsk Arseny Gorokhov … Copyright daim ntawv pov thawj No. 383005.

Lawv hais tias niaj hnub no muaj ntau tus kws tshaj lij programmers thiab lwm tus kws tshaj lij los ntawm Russia ua haujlwm hauv Silicon Valley hauv California. Thiab lub foob pob hluav taws motors TSI-180 Cov neeg Amelikas tseem yuav los ntawm Russia, vim lawv tus kheej tseem tsis tuaj yeem tsim tau. Tebchaws Meskas tsis muaj nuclear icebreakers, uas Russia tau ua tiav tau ntev lawm; lawv tseem tsis tau muaj peev xwm tsim tau lub foob pob hluav taws xob nuclear, uas peb lub tebchaws tau ua lawm.

Yog li cov kev rau txim uas tau tshaj tawm rau peb hnub no Teb chaws USA nyob rau hauv ntau yam, ua tsaug rau Lavxias teb sab "lub hlwb" thiab invention ntawm Lavxias teb sab ci ntsa iab engineers thiab cov kws tshawb fawb, lawv lawv tus kheej los ua ib tug advanced hwj chim, thiab lawv tseem ua tsis tau yog tsis muaj lawv.

Lub tebchaws United States ib txwm nyiam ua qhov txawv ntawm nws txoj kev lag luam ua tiav lwm tus neeg inventions … Yog li tej zaum tam sim no cov kev nplua uas lawv tau tshaj tawm yuav tsim cov xwm txheej rau peb thaum kawg pib ua ib yam?
