Lub davhlau los ntawm Beijing mus rau Shanghai hauv ib nrab ib teev xwb - lub dav hlau neeg nrog caij supersonic tab tom taug kev.

Nyob rau ntawm lub rooj sib tham tsis ntev los no Tuam Tshoj Aviation Science thiab Technology Conference nyob rau hauv Wuxi, Jiangsu, supersonic neeg nrog caij dav hlau tau tshwm sim los ua lub ntsiab lus tseem ceeb ntawm cov kev sib tw tseem ceeb ntawm kev tshawb fawb thiab thev naus laus zis rau xyoo 2026. Ib pab neeg Suav tam sim no tsom ntsoov rau nws txoj kev siv zog rau kev ua tiav ntawm kev ua tiav "Beijing-Stohai" {2} feeb tom ntej.
Lub caij no, NASA's X-59 "Quiet SuperSonic Technology" (QueSST) tus qauv ua qauv tsoo lub suab thaiv thaum lub sijhawm sim davhlau rau lub Rau Hli, thaum lub tuam txhab ntiag tug Boom Supersonic tab tom tsom mus rau lub lag luam tawm qhov rais nyob ib ncig ntawm 2030 rau nws lub dav hlau Overture. Raws li qhov tshwm sim, Asmeskas tab tom txav mus tshem cov kev txwv ntawm kev ya davhlau supersonic hla av.
Nrog cov teeb meem ntawm kev tswj hwm kev yooj yim ntawm ib sab tes thiab kev txhim kho thev naus laus zis txuas ntxiv mus rau lwm qhov, "nthwv dej thib ob" ntawm supersonic neeg caij aviation tau nrawm nrawm.
Vim li cas cov dav hlau fighter ntev tau muaj peev xwm ntawm lub davhlau supersonic, thaum pej xeem aviation lags tom qab?
Cov lus teb tsis yog nyob rau hauv seb lub dav hlau * tuaj yeem * ya, tab sis seb lawv puas tuaj yeem ya tau ruaj khov, kev lag luam, thiab ua raws li cov cai.
**Differing lub hom phiaj profiles:** Fighter jets yog tsim rau kev sib ntaus sib tua, feem ntau caij nkoj ntawm subsonic speeds thiab ua luv luv bursts ntawm supersonic davhlau (txawm hais tias ib co qauv tau ua tiav supersonic cruise muaj peev xwm). Nyob rau hauv sib piv, supersonic neeg nrog caij dav hlau yuav tsum tuav ib tug cruise ceev ntawm Mach 1.5-2 nyob rau hauv high altitudes rau ncua sij hawm, tso sustained, siab -load xav tau ntawm lub cav, cov qauv kev ntseeg, thiab thermal tswj systems.
** Kev sib txawv ntawm qhov sib txawv:** Fighter jets feem ntau siv cov cav nruab nrog tom qab burners; thaum cov no ua kom muaj zog loj heev rau lub sijhawm luv, lawv haus roj ntawm tus nqi siab heev. Cov neeg tsav dav hlau hauv pej xeem xav tau kev caij nkoj zoo tshaj plaws uas tsis muaj kev cuam tshuam tom qab, thaum tseem ua tau raws li cov qauv suab nrov thiab emissions nruj heev- ib qho kev sib tw nyuaj tshaj li qhov tsuas yog ua tiav ib lub davhlau supersonic.
**Aerodynamic thiab structural trade-offs:** Supersonic flight generates intense shock waves and aerodynamic heating, necessitating thinner tiss, complex air intakes, and high-temperature-resistant material. Cov kev xav tau no cuam tshuam rau kev thauj mus los thiab tsaws kev ua haujlwm, lub peev xwm thauj khoom, thiab ntau yam, thaum tsav tsheb nce kev tsim khoom thiab tu nqi.
**Txoj cai thiab kev lees txais kev sib raug zoo:** Txij li xyoo 1970s, Tebchaws Asmeskas thiab lwm lub tebchaws tau txwv lossis txwv tsis pub muaj kev ya dav hlau hla av. Qhov laj thawj tseem ceeb yog "sonic boom" tsim thaum lub sijhawm ya, uas ua rau muaj suab nrov nrov hauv av; civil aircraft yuav tsum nruj me ntsis raws li airworthiness thiab suab nrov txoj cai. Hauv lwm lo lus, qhov kev sib tw rau cov neeg tsav dav hlau supersonic tsis yog nyob rau hauv "kev rhuav tshem lub suab nrov," tab sis nyob rau hauv "txhaum lub suab nrov nrov, txo cov roj noj, thiab ua raws li kev tswj hwm."
Keeb kwm, tsuas yog ob lub dav hlau supersonic nkag mus rau kev lag luam: Anglo-French Concorde thiab Soviet Tu-144. Thaum lawv pom tau hais tias muaj peev xwm ua tau, lawv kuj tau nthuav tawm qhov tsis muaj kev lag luam muaj peev xwm-tshwj xeeb, kev txwv txoj kev vim muaj suab nrov nrov, kev lag luam tsis zoo, thiab kev ntxhov siab txog kev cuam tshuam ib puag ncig thiab kev nyab xeeb.
Qhov no yog qhov kev sib tw tseem ceeb uas lub ntiaj teb tshiab nthwv dej ntawm supersonic airliner txoj kev loj hlob yuav tsum tau hais ncaj qha.
Ntiaj teb no Supersonic Airliner Development
Thaum Lub Rau Hli 5, 2026, NASA's X-59 tus qauv dav hlau tsoo lub suab barrier thawj zaug. Lub ntsiab lus tseem ceeb no tau cim nws txoj kev hloov pauv ntawm subsonic lub hnab ntawv sim mus rau theem kev sim supersonic- tau nkag mus rau theem ntawm kev siv lub suab nrov-thaum lub sijhawm uas cov yam ntxwv ntawm nws cov hauv av sonic boom thaum lub davhlau supersonic yuav raug ntsuas.
Qhov tseem ceeb tshaj yog qhov kev hloov pauv hauv txoj cai: 2025 White House tus thawj coj xaj tau hais rau FAA txhawm rau txhawm rau hloov pauv kev txwv nrawm nrog cov qauv suab nrov- yog li tso cai rau overland supersonic davhlau uas ua rau tsis muaj suab nrov boom- thiab tsim kom muaj lub sijhawm rau cov qauv suab nrov no.
Thaum Lub Ib Hlis 28, 2025, XB-1 demonstrator aircraft tsim los ntawm tus kheej US tuam txhab Boom Supersonic ua tiav nws lub dav hlau supersonic, mus txog qhov ceev ntawm Mach 1.122.
Lub XB-1 yog ib qho -them peb txheej txheem thev naus laus zis rau "Overture" kev lag luam supersonic airliner tam sim no tsim los ntawm Boom. Lub Overture yog tsim los rau kev caij nkoj ceev ntawm Mach 1.7 thiab qhov siab tshaj plaws ntawm Mach 2.2, nrog rau qhov siab tshaj plaws ntawm 4,250 mais thiab muaj peev xwm zaum ntawm 64 txog 80 tus neeg caij tsheb.
Raws li Boom cov phiaj xwm, thawj lub dav hlau ua tiav yuav tsum yob tawm ntawm cov kab sib dhos hauv 2026, nrog rau lub dav hlau dav hlau tsom rau xyoo 2027 thiab kev lag luam ua lag luam rau xyoo 2029-2030.
Ntxiv nrog rau Boom thiab NASA, lwm cov haujlwm ua qauv qhia-xws li Hermeus's Quarterhorse- kuj tseem tab tom pib.
Cov kws tshawb fawb Suav tseem tab tom tshawb nrhiav txoj hauv kev los txo cov suab nrov los ntawm cov neeg caij dav hlau supersonic. Hauv xyoo 2025, tus ntsuas ntsuas -tus qauv ua qauv tsim los ntawm Tianmushan Laboratory tau ua tiav qis- kev sim davhlau ceev; lub dav hlau nta ib tug "peb-nto ntxiv T-tail" aerodynamic configuration tsim los disperse thiab soften lub shockwaves uas feem ntau tsom rau pem hauv ntej ntawm lub aircraft.
Tianmushan Laboratory npaj yuav ua cov kev sim supersonic davhlau los ntawm qhov kawg ntawm 2026, aiming kom ntseeg tau tias lub sonic boom generated los ntawm lub dav hlau tsis tshaj 80 decibels.
