Iyo "shower system" pane yekutanga shongwe.
Kana roketi rakatangwa, rinowanzoburitsa ruzha rwema decibels angangoita mazana maviri, uye mune dzimwe nguva rinosvika mazana maviri nemakumi maviri emadecibel. Kuuraya kweiyi nhanho yeruzha hakufanirwe kurerutsa, uye kana ikasadzorwa, inogona kukuvadza miviri yedu, kutanga mapuratifomu, zvivakwa zvakatenderedza, zvichingodaro.
Nokudaro, roketi ichatangwa panguva yekurwadziwa kwe "mvura inotonhora", iyo haigone kuti isu titonhorere pasi, asiwo nokuda kwekuderedza ruzha rwe rocket.
Rocket Academy yeBeijing Institute of Space Launch Technology yakagadzira kutonhora uye kuderedza ruzha "shower system" - hombe yekuyerera mvura yekupfapfaidza kutonhora uye kuderedza ruzha.
Iyi sisitimu yakakamurwa kuita nhanho mbiri, nhanho mukutanga pachikuva, chitundumuseremusere injini kubatidza, ichapa iyo yekumisikidza chikuva pfapfaidzo ye5 masendimita gobvu yekudzivirira mvura; nhanho yechipiri papuratifomu yekumisikidza kumativi ese e5-mita yakakwirira-yakakwirira pyloni, muroketi yakabhururuka kusvika pamamita mashanu kubva kumusoro mushure me roketi kuenda kumashure kwemuseve body flame centre yekupfapfaidza yemvura, mazinga maviri ezvivakwa zvekupfapfaidza akapfapfaidzwa kweanopfuura masekonzi makumi maviri, achipfira kunze matani mazana mana emvura. Chipfapfaidzo chemvura chinodziiswa nemasaisai eruzha, chichishandura simba remasaisai eruzha kuita kupisa, nokudaro kuchideredza ruzha pakurutswa kwedu kusvika kunosvika 5 decibel uye kuderedza njodzi dzemutsindo wepamusoro-decibel.
Mvura inobva mutangi hombe remvura riri pamusoro peshongwe yekumisikidza, uye pamatani mazana mana emvura yakapfapfaidzwa, 400% ichanyungudutswa mumhepo, nepo 30% ichiyerera ichienda nemumatangi ekubvisa, uye kubuda kwemvura kunobvisa kupisa kwakawanda, kuchitonhora pasi pepakati pepuratifomu yepuratifomu nemadhigirii 60 Celsius.
Iyo "mudziyo unotora ruzha" mune fairing.
Sezvo roketi inokwira, kuyerera kwemhepo kunokonzeresa ruzha rwakasimba nekuda kwekukurumidza kunowedzera. Sezvakangoita kuvhuvhuta kwakajairika pabepa, kuchaita kuti bepa rinzwike, kufefetera kwemhepo kuvhuvhuta kuburikidza nekuita kweiyo dhayamita hombe, hukuru hukuru hwechimiro chemadziro matete, zvinokonzeresa anopfuura 140 decibels eruzha. Noise ichaparadza fairing mukati memidziyo yemagetsi uye chimiro chese, kunyanya, chinokonzera kuneta kukuvadza kune zvakakosha zvikamu, zvakanyanya kuderedza kuvimbika kwehurongwa hwose. Dzimwe nguva maroketi anoita mishoni dzemuchadenga, uye mukati memuchadenga mune chitundumuseremusere mune vazivi vemuchadenga, uye ruzha rwunokuvadza zvakanyanya hutano hwevachadenga.
Mukupindura dambudziko iri, Dhipatimendi Rezvekugadzira reRocket Academy rakagadzira acoustic cover layer, inoiswa pamadziro emukati meiyo fairing uye inovhara nzvimbo ye30 square metres, ine ukobvu hwemasendimita 4.5 chete.
Chifukidziro cheacoustic chakanyanya kuumbwa nefoam ine melamine porous. Kana mafungu eruzha akaitika pamusoro pechinhu chine porous acoustic, chikamu chawo chinoratidzwa kubva pamusoro pechinhu chacho, uye chimwe chikamu chinotumirwa mukati mechinhu kuburikidza nemaburi akabatana nenyika yekunze. Kudengenyeka kwemafungu eruzha muchinhu chacho kunokonzera kufamba kwemhepo mukati meburi, zvichiita kuti ikwizane nemadziro eburi. Pasi pesimba rekukweshana uye simba rinonamira, chikamu chesimba rinoshandurwa kuita simba rekupisa, zvekuti acoustic wave attenuation, reflective sound energy inoderedzwa simba kuti iwane simba rekunyudzwa kweacoustic. Pamusoro pezvo, kuchinjana kwekupisa pakati pemhepo nemadziro eburi nezvinhu zvinokonzera kurasikirwa nekupisa, izvo zvinokonzerawo kuderedza simba reruzha.
Iine acoustic yekuvhara layer, ruzha mukati me fairing inogona kudzikiswa ne5-8 dB mu frequency bhendi pamusoro pe500 Hz, uye huwandu hwese hwekumanikidza hwekurira hunoderedzwa ne3 dB. Pamusoro pekugadzira acoustic yekuvharisa layer yemaroketi, melamine foam inogona zvakare kushandiswa kudzikisa ruzha mu space shuttle, ndege dzekutengesa, helikopta, varwi uye zvichingodaro.
Panguva imwecheteyo, masayendisiti edu akatora matanho akawanda ekudzivirira-ruzha ezvikepe zvemuchadenga pamwe nemasutu emuchadenga. Pasi peakawanda mhedzisiro yeacoustic cover layer, Helmholtz resonator, spacecraft, spacesuit, nezvimwewo, ruzha mukati meiyo fairing rwakadzorwa zvinobudirira, uye hutano hwekunzwa hwevazivi vemuchadenga hwakavimbiswa zvakavimbika.

Mimwe mifananidzo uye zvinyorwa zvinoburitswa kubva paInternet, uye kodzero yacho ndeyemunyori wekutanga. Kana paine kutyorwa kwekodzero, ndapota taura nesu kuti tibviswe.
