"Shower system" pa nsanja yotsegulira.
Roketi ikatulutsidwa, imatulutsa phokoso la ma decibel pafupifupi 200, ndipo nthawi zina mpaka ma decibel 220. Kupha kwa phokoso la phokosoli sikuyenera kunyalanyazidwa, ndipo ngati sikusamalidwa, zikhoza kuwononga matupi athu, mapulatifomu otsegulira, nyumba zozungulira, ndi zina zotero.
Choncho, roketi idzayambitsidwa panthawi ya ululu wa "kusamba kozizira", zomwe sizingathe kuti tizizizira, komanso kuchepetsa phokoso la rocket.
Rocket Academy ya Beijing Institute of Space Launch Technology idapanga njira yoziziritsira komanso yochepetsera phokoso "yosamba" - njira yayikulu yozizirira yopopera madzi ndi kuchepetsa phokoso.
Dongosolo ili lagawidwa m'magulu awiri, mulingo mu nsanja Launch wosanjikiza, rocket injini poyatsira, adzakupatsani Launch nsanja kutsitsi wosanjikiza 5 masentimita wandiweyani chitetezo madzi wosanjikiza; mlingo wachiwiri mu nsanja Launch pa mbali zonse za 5-mita mkulu-okwera pylons, mu roketi anawulukira kwa 5 mamita pamwamba pambuyo roketi kumbuyo kwa muvi thupi lawi lawi likulu kutsitsi madzi, magawo awiri a kupopera mbewu mankhwalawa kwa masekondi oposa 20, kupopera mbewu mankhwalawa kunja matani 400 a madzi. Kupopera kwa madzi kumatenthedwa ndi mafunde a phokoso, kutembenuza mphamvu ya mafunde a phokoso kukhala kutentha, motero kuchepetsa phokoso pa kutsegulira kwathu kukhala pafupifupi ma decibel 140 ndi kufooketsa zoopsa za phokoso lapamwamba la decibel.
Madzi amachokera ku thanki lalikulu lamadzi pamwamba pa nsanja yotsegulira, ndi matani 400 a madzi opopera, 30% adzasungunuka mumlengalenga, pamene 60% idzatuluka kudzera mu akasinja opotoka, ndipo kutuluka kwa madzi kumachotsa kutentha kwakukulu, kuziziritsa pansi pakatikati pa nsanja yoyambira ndi madigiri 1,000 Celsius.
"Zida zotulutsa mawu" mu fairing.
Pamene rocket ikukwera, kutuluka kwa mpweya kumayambitsa phokoso lamphamvu chifukwa cha liwiro lowonjezereka. Monga momwe kuwomba kwanthawi zonse pamapepala, kumapangitsa kuti pepala likhale lomveka, kuwulutsa kwa mpweya kupyola mumsewu waukuluwu, kukula kwakukulu kwa khoma lopyapyala, kumapangitsa ma decibel 140 a phokoso. Phokoso lidzawononga fairing mkati mwa zipangizo zamagetsi ndi dongosolo lonse, makamaka, zidzachititsa kutopa kuwonongeka kwa zigawo zikuluzikulu, kuchepetsa kwambiri kudalirika kwa dongosolo lonse. Nthawi zina maroketi amapita kumlengalenga, ndipo mkati mwa chiwonetserocho mumakhala oyenda m'mlengalenga, ndipo phokosolo limawononga kwambiri thanzi la oyenda mumlengalenga.
Pofuna kuthana ndi vutoli, Dipatimenti Yopanga Zonse ya Rocket Academy yapanga chivundikiro choyimbira, chomwe chimayikidwa pakhoma lamkati la fairing ndipo chimakwirira malo a 30 lalikulu mamita, ndi makulidwe a masentimita 4.5 okha.
Chivundikiro cha mawu chimapangidwa makamaka ndi thovu la melamine lokhala ndi mapokoso. Pamene mafunde a mawu achitika pamwamba pa zinthu zotulutsa mawu, gawo lina limaonekera kuchokera pamwamba pa zinthuzo, ndipo gawo lina limatumizidwa mkati mwa zinthuzo kudzera m'mabowo olumikizidwa ndi dziko lakunja. Kugwedezeka kwa mafunde a mawu kulowa muzinthuzo kumayambitsa kuyenda kwamphamvu kwa mpweya mkati mwa dzenje, zomwe zimapangitsa kuti ukhudze khoma la dzenjelo. Pansi pa mphamvu ya kukangana ndi kukhuthala, gawo lina la mphamvu ya mawu limasandulika kukhala mphamvu yotentha, kotero kuti kuchepa kwa mafunde a mawu, mphamvu ya mawu yowonetsedwa imafooka kuti ikwaniritse zotsatira za kuyamwa kwa mawu. Kuphatikiza apo, kusinthana kwa kutentha pakati pa mpweya ndi khoma la dzenje ndi zinthuzo kumayambitsa kutayika kwa kutentha, komwe kumayambitsanso kuchepa kwa mphamvu ya mawu.
Ndi wosanjikiza zokutira zokutira, phokoso mkati fairing akhoza kuchepetsedwa ndi 5-8 dB mu pafupipafupi bandi pamwamba 500 Hz, ndi okwana kuthamanga mulingo amachepetsedwa pafupifupi 3 dB. Kuphatikiza pakupanga zokutira zotchingira za roketi, thovu la melamine litha kugwiritsidwanso ntchito pochepetsa phokoso mumlengalenga, ndege zamalonda, ma helikoputala, omenyera nkhondo ndi zina zotero.
Panthawi imodzimodziyo, asayansi athu atenga njira zambiri zotsutsana ndi phokoso lazoyenda zam'mlengalenga komanso zamlengalenga. Pansi pa zotsatira zingapo za chivundikiro cha acoustic, Helmholtz resonator, spacecraft, spacesuit, etc., phokoso mkati mwa fairing layendetsedwa bwino, ndipo thanzi lakumva la astronaut latsimikiziridwa modalirika.
Kuti mudziwe zambiri zokhudza thovu la melamine la SINOYQX, chonde titumizireni uthenga pa [email protected] kapena tiyimbireni pa +86-28-8411-1861.
Zithunzi ndi zolemba zina zidapangidwanso kuchokera pa intaneti, ndipo kukopera ndi kwa wolemba woyamba. Ngati pali kuphwanya copyright, chonde titumizireni kuti tichotse.
