Nyob rau hauv 2017, lub rooj sib tham txhua xyoo European Space Debris Conference tau tuav. Ntau tshaj li peb puas tus kws tshawb fawb los ntawm ntau qhov chaw ntawm lub ntiaj teb tau sim txiav txim siab txoj hauv kev zoo ntawm kev tawm tsam cov pa phem ntawm qhov chaw nyob ze ntawm lub ntiaj teb.

Raws li qhov tshwm sim ntawm lub rooj sib tham, kwv yees li 750 txhiab cov khib nyiab sib txawv tshaj 1 cm (hauv ntu ntu) tau tshaj tawm, thiab lwm 166 lab cov khib nyiab ntau tshaj 1 hli.

Qhov ceev ntawm qhov chaw khib nyiab hauv lub orbit piv rau lwm yam khoom tuaj yeem ncav cuag 10 km / sec. Xws li kev kub ceev txhais tau hais tias cov khoom nqa colossal kinetic zog thiab kev sib tsoo nrog lub chaw ua haujlwm ntawm cov khib nyiab me me yuav ua rau muaj kev puas tsuaj loj rau yav tom ntej, mus txog rau qhov ua tiav rau hauv lub xeev tsis ua haujlwm.

Nov yog cov txiaj ntsig ntawm cov khib nyiab pov tseg ntawm International Chaw Nres Tsheb:

Nyob rau sab laug hauv daim duab koj tuaj yeem pom cov txheej txheem txhuas hlau 102 hli tuab. tiv thaiv cov blocks supercritical ntawm ISS, uas tau txais ib daim yas zoo li no:

… ntawm qhov ceev ntawm 7,000 meters ib ob.

Nyob rau sab xis ntawm tib daim duab, koj pom ib qho 38 mm tawg. aluminium tiv thaiv rau hauv uas 6x12 mm ntsia liaj qhov rooj poob tangentially. ntawm qhov ceev tib yam

Ib daim ntawv hlau yog ntsia rau pem hauv ntej ntawm lub thaiv thaiv aluminium:

… uas tau txais tib lub bolt:

Muaj cov khaubncaws sab nraud povtseg ntawm fiberglass thiab ceramics nyob rau hauv pem hauv ntej ntawm aluminium.

Thiab qhov no yog kev tiv thaiv los ntawm Lavxias teb sab ISS Zvezda module pierced nrog ib tug txhuas bolt ntawm ib tug ceev ntawm 6800 m / s. Ib yam dab tsi ntau bolts ya hauv qhov chaw:-)

Portholes tau txais nws thiab. Lub thickness ntawm lub iav yog 14 hli. Cov kab nrib pleb zoo li no nyob hauv nws thaum cov xuab zeb tsoo ntawm qhov ceev ntawm 7152 m / s.

Los ntawm txoj kev, portholes ntawm qhov chaw nres tsheb muaj plaub lub tsom iav, rau kev tiv thaiv tiav, txwv tsis pub koj yeej tsis paub. Hauv keeb kwm yav dhau yog sab nraub qaum ntawm 102mm txhuas thaiv tau pom saum toj no.

Astronaut Timothy Peak nyob rau hauv ib qho ntawm cov duab pom lub qhov rais porthole nrog tawg.

Qhov kev txhaj tshuaj nrog lub qhov rais "chob" tau coj los ntawm Tim Peek hauv Cupola, ib qho qauv txuas nrog rau International Chaw Nres Tsheb (ISS) thaum Lub Ob Hlis 2016. Lub module nyob rau hauv daim ntawv ntawm ib tug panoramic soj ntsuam dome muaj xya pob tshab qhov rais mus txog 80 cm nyob rau hauv lub cheeb; los ntawm nws, nws yog qhov yooj yim los soj ntsuam qhov chaw ntawm lub ntiaj teb, qhov chaw sab nrauv thiab tib neeg lossis cov khoom siv ua haujlwm hauv qhov chaw sab nrauv.

Tag nrho cov qauv uas hnyav 1.8 tons thiab 1.5 meters siab yog hais txog 2 meters inch. Tag nrho cov portholes yog ua los ntawm pob tshab fused quartz, thiab los ntawm sab nraud lawv tau nruab nrog tsis siv neeg shockproof li (dampers) los tiv thaiv lub module los ntawm micrometeorites thiab qhov chaw khib nyiab. Txawm li cas los xij, txhua qhov kev hem thawj hauv qhov chaw tsis tuaj yeem zam tau: tus kws sau hnub qub nco qab qhov no los ntawm kev tshaj tawm ib daim duab ntawm lub qhov rais, uas muaj ib lub nti nrog txoj kab uas hla ntawm 7 hli pom meej.

Thiab qhov no yog tarp rau kaw lub docking hatches ntawm chaw nres tsheb thaum lub sij hawm tsim kho.

Lub tarp dai nyob rau hauv ib lub hatches ntawm lub thoob ntiaj teb chaw nres tsheb yuav luag ob xyoos. Nws yog tsim los ntawm ntau txheej fiberglass, ceramic, iav thiab ultra-muaj zog steel fibers. Cov thaj ua rau thaj yog rau kev sib txuas lus thaum tsim kho, thiab cov ntawv nplaum xiav thiab ntsuab yog cov pob zeb me me thiab cov khib nyiab uas pom tom qab cov ntaub pua plag rov qab los rau hauv av.

Hmoov tsis zoo, tus nqi ntawm cov khib nyiab tas li loj tuaj. Piv txwv li, xyoo 2007, Suav tau sim lub foob pob hluav taws los ntawm kev tua ntawm lub satellite. Qhov no ntxiv 3,000 cov khib nyiab tshiab rau lub voj voog.

Nyob rau hauv 2009, ua tsis tau tejyam Lavxias teb sab spacecraft Cosmos 2251 tsoo nrog lub American kev sib txuas lus satellite Iridium - +2000 khib nyiab tawg.

Qhov no tsis yog thawj zaug qhov chaw khib nyiab tau ua rau ISS puas lawm. Nyob rau hauv 2013, ib tug me me "pebble los ntawm qhov chaw" tsoo los ntawm lub hnub ci vaj huam sib luag.

Qhov no yog li cas cov khib nyiab pov tseg ntawm ISS tshwm sim.
