"Inkqubo yeshawari" kwinqaba yokuqalisa.
Xa kuqaliswa i-rocket, idla ngokukhupha ingxolo ephantse ibe ngama-200 eedecibels, kwaye kwezinye iimeko ide ibe ngama-220 decibels. Ukubulawa kweli nqanaba lengxolo akufanele kujongelwe phantsi, kwaye ukuba kushiywe kungaqwalaselwa, kunokuthi konakalise imizimba yethu, amaqonga okuqalisa, izakhiwo ezijikelezileyo, njalo njalo.
Ngoko ke, i-rocket iya kuqaliswa ngexesha leentlungu "zokuhlamba ezibandayo", ezingenakukwazi ukupholisa kuphela, kodwa kunye nokunciphisa ingxolo ye-rocket.
I-Rocket Academy ye-Beijing Institute of Space Launch Technology iyile ukupholisa kunye nokunciphisa ingxolo "inkqubo yeshawari" - ukupholisa kwamanzi okugeleza okukhulu kunye nenkqubo yokunciphisa ingxolo.
Le nkqubo yahlulwe ngamanqanaba amabini, inqanaba kwiqonga leqonga lokuphehlelela, ukuvutha kwe-injini ye-rocket, iya kunika iqonga lokutshiza iqonga lomaleko ongqindilili we-5 cm wokhuselo lwamanzi; inqanaba lesibini kwiqonga lokuphehlelela kumacala omabini eepylons eziimitha ezi-5 eziphakamileyo, kwirokethi yabhabha yaya kuthi ga kwiimitha ezi-5 ukuphakama emva kwerokethi ukuya ngasemva kotolo lomzimba welangatye lokutshiza amanzi, amanqanaba amabini okutshiza atshizwe ngaphezulu kwemizuzwana engama-20, etshiza iitoni ezingama-400 zamanzi. Isitshizi samanzi sifudunyezwa ngamaza esandi, siguqula amandla amaza esandi abe bubushushu, ngaloo ndlela sinciphisa ingxolo ekusungulweni kwethu ukuya kutsho malunga ne-140 decibels kwaye senza buthathaka iingozi zengxolo ye-decibel ephezulu.
Amanzi avela kwitanki enkulu yamanzi phezu kwenqaba yokuqalisa, kwaye kwiitoni ezingama-400 zamanzi atshiziweyo, i-30% iya kuphuphuma emoyeni, ngelixa i-60% iya kumpompoza ihambe ngeetanki ze-deflector, kwaye ukuqhuma kwamanzi kususa ubushushu obuninzi, ukupholisa indawo engundoqo yeqonga lokuqalisa malunga ne-1,000 degrees Celsius.
"Isixhobo esifunxa isandi" kwi-fairing.
Njengoko i-rocket iphakama, ukuhamba komoya kuya kubangela ingxolo enamandla ngenxa yokwanda kwesantya. Kanye njengokuvuthuza okuqhelekileyo ephepheni, kuya kwenza iphepha elithi "pop" livakale, ukuhamba komoya kuphephezela kwi-fairing ye-diameter enkulu, ubungakanani obukhulu besakhiwo esinodonga olubhityileyo, luya kubangela ngaphezu kwe-140 decibels yengxolo. Ingxolo iya kutshabalalisa i-fairing ngaphakathi kwezixhobo ze-elektroniki kunye nesakhiwo ngokubanzi, ngokukodwa, kuya kubangela umonakalo wokudinwa kumacandelo abalulekileyo, ukunciphisa kakhulu ukuthembeka kwenkqubo yonke. Ngamanye amaxesha imijukujelwa yenza imisebenzi yasemajukujukwini elawulwa ngabantu, kwaye ngaphakathi kwi-fairing sisiphekepheke apho oosomajukujuku bakhona, kwaye ingxolo iya konakalisa kakhulu impilo yoosomajukujuku.
Ukuphendula kule ngxaki, iSebe lezoYilo ngokubanzi le-Rocket Academy liphuhlise i-acoustic cover layer, ebekwe kudonga lwangaphakathi lwe-fairing kwaye igubungela indawo ye-30 square metres, kunye nobukhulu be-4.5 centimeters kuphela.
Umaleko we-acoustic cover wenziwe kakhulu yi -melamine porous foam. Xa amaza esandi esenzeka kumphezulu we-acoustic material enemingxuma, inxalenye yawo ibonakaliswa ukusuka kumphezulu wezinto, kwaye enye inxalenye idluliselwa ngaphakathi kwezinto ngemingxuma eqhagamshelwe kwihlabathi langaphandle. Ukungcangcazela kwezandi kwizixhobo kubangela intshukumo enamandla yomoya ngaphakathi kwimingxuma egqithayo, okwenza ukuba igutyungelwe ludonga lomngxuma. Phantsi kwesenzo sokungqubana kunye namandla aqinileyo, inxalenye yamandla e-acoustic iguqulwa ibe ngamandla obushushu, ukuze ukuncitshiswa kwezandi ze-acoustic, amandla esandi abonakalisiweyo abuthathaka ukuze kufezekiswe isiphumo sokufunxwa kwe-acoustic. Ukongeza, ukutshintshiselana kobushushu phakathi komoya nodonga lomngxuma kunye nezinto kubangela ukulahleka kobushushu, okubangela ukuncitshiswa kwamandla esandi.
Ngomaleko ogqumayo we-acoustic, ingxolo ngaphakathi kwi-fairing ingancitshiswa nge-5-8 dB kwibhendi yefrikhwensi ngaphezulu kwe-500 Hz, kwaye inqanaba loxinzelelo lwesandi lilonke liyancitshiswa malunga ne-3 dB. Ukongeza ekwenzeni i-acoustic covering layer for rockets, i-melamine foam inokusetyenziselwa ukunciphisa ingxolo kwisiphekepheke, iinqwelomoya zentengiso, iihelikopta, abalwi njalo njalo.
Kwangaxeshanye, oosonzululwazi bethu bathathe amanyathelo amaninzi okuthintela ingxolo kwiziphekepheke kunye neesuti zasemajukujukwini. Ngaphantsi kweempembelelo ezininzi zomaleko we-acoustic cover, i-Helmholtz resonator, i-spacecraft, i-spacesuit, njl.
