"Isistimu yeshawa" embhoshongweni wokuqalisa.
Lapho i-rocket yethulwa, ngokuvamile ikhipha umsindo ocishe ube ngama-decibel angu-200, kanti kwezinye izikhathi ufinyelela kuma-decibel angu-220. Ukubulawa kwaleli zinga lomsindo akufanele kuthathwe kancane, futhi uma kungabhekwanga, kungahle kulimaze imizimba yethu, kwethulwe amapulatifomu, izakhiwo ezizungezile, nokunye.
Ngakho-ke, i-rocket izokwethulwa ngesikhathi sobuhlungu "bokugeza okubandayo", okungenakukwazi ukupholisa kuphela, kodwa futhi nokunciphisa umsindo we-rocket.
I-Rocket Academy yaseBeijing Institute of Space Launch Technology yaklama “isistimu yeshawa” yokupholisa nomsindo yokunciphisa umsindo - uhlelo lokupholisa isifutho samanzi agelezayo kanye nohlelo lokunciphisa umsindo.
Lolu hlelo luhlukaniswe ngamaleveli amabili, izinga kungqimba yesikhulumi sokwethulwa, ukuthungela kwenjini yerokhethi, kuzonikeza isifutho seplathifomu ungqimba lwesendlalelo sokuvikela amanzi esingu-5 cm obukhulu; Izinga lesibili endaweni yokwethulwa ezinhlangothini zombili zezigqoko eziphakeme ezingamamitha ama-5, irokhethi indize ifike kumamitha ayi-5 ukuphakama ngemuva kwerokhethi eya ngemuva kwesifutho samanzi sesikhungo somcibisholo, amazinga amabili ezindawo zokufafaza afafazwe imizuzwana engaphezu kuka-20, efafaza amathani angama-400 amanzi. Isifutho samanzi sishiswa amagagasi omsindo, siguqule amandla amaza omsindo abe ukushisa, ngaleyo ndlela sinciphise umsindo ekuqaliseni kwethu ukuba sibe ngama-decibel angu-140 futhi senze buthaka izingozi zomsindo we-decibel ephezulu.
Amanzi aphuma ethangini elikhulu lamanzi eliphezu kombhoshongo wokwethulwa, futhi kumathani angu-400 amanzi afuthwe, u-30% uzohwamuka emkhathini, kuyilapho u-60% uzogeleza udlule emathangini okuphambukisa, futhi ukuhwamuka kwamanzi kususe ukushisa okuningi, kuphole phansi indawo ewumgogodla yesikhulumi sokuqalisa ngo-1,000 degrees Celsius.
“Imishini emunca umsindo” embukisweni.
Njengoba i-rocket ikhuphuka, ukugeleza komoya kuzodala umsindo oqinile ngenxa yejubane elikhulayo. Njengokuvunguza okuvamile ephepheni, kuzokwenza iphepha lizwakale elithi “pop”, ukugeleza komoya okuvunguza ngokubonakala kwalo bubanzi obukhulu, usayizi omkhulu wesakhiwo esinezindonga ezincane, kuzodala umsindo ongaphezu kwama-decibel angu-140. Umsindo uzocekela phansi i-fairing ngaphakathi kwempahla ye-elekthronikhi futhi ukwakheka okuphelele, ikakhulukazi, kuzodala ukulimala kokukhathala ezingxenyeni ezibalulekile, kunciphise kakhulu ukuthembeka kwalo lonke uhlelo. Kwesinye isikhathi amarokhethi enza imisebenzi yasemkhathini eyenziwe ngumuntu, futhi ingaphakathi le-fairing yindizamkhathi lapho osomkhathi bekhona, futhi umsindo uzolimaza kakhulu impilo yosomkhathi.
Ukuphendula le nkinga, uMnyango Wokuklama Okuphelele we-Rocket Academy uthuthukise isendlalelo sekhava ye-acoustic, esibekwe odongeni olungaphakathi lwe-fairing futhi simboze indawo engamamitha-skwele angama-30, enogqinsi lwamasentimitha angu-4.5 kuphela.
Isendlalelo sesembozo se-acoustic sakhiwe kakhulu nge -melamine foam enezimbobo. Lapho amaza omsindo eba khona ebusweni bezinto ezimbobo ze-acoustic, ingxenye yawo iboniswa ebusweni bezinto, kanti enye ingxenye idluliselwa ngaphakathi kwezinto ngemigodi exhunywe ezweni langaphandle. Ukudlidliza kwegagasi lomsindo eliya ezintweni kubangela ukunyakaza okunamandla komoya ngaphakathi kwembobo edlulayo, okwenza ukuthi igudle udonga lwembobo. Ngaphansi kwesenzo sokungqubuzana namandla aqinile, ingxenye yamandla e-acoustic iguqulwa ibe amandla okushisa, ukuze ukuncishiswa kwamagagasi e-acoustic, amandla omsindo abonakalisiwe ancishiswe ukuze kufezwe umphumela wokumuncwa kwe-acoustic. Ngaphezu kwalokho, ukushintshana kokushisa phakathi komoya nodonga lwembobo nezinto ezibangela ukulahleka kokushisa, okubangela nokuncipha kwamandla omsindo.
Ngesendlalelo sesembozo se-acoustic, umsindo ongaphakathi kwe-fairing ungancishiswa ngo-5-8 dB kubhendi yefrikhwensi engaphezu kuka-500 Hz, futhi isamba sezinga lokucindezela komsindo lehliswa cishe ngo-3 dB. Ngaphezu kokwenza isendlalelo se-acoustic sesembozo samarokhethi, igwebu le-melamine lingasetshenziselwa ukunciphisa umsindo ku-shuttle yasemkhathini, izindiza zezentengiselwano, izindiza ezinophephela emhlane, izilwi nokunye.
Ngesikhathi esifanayo, ososayensi bethu bathathe izinyathelo eziningi zokunqanda umsindo zemikhumbi-mkhathi kanye nezingubo zasemkhathini. Ngaphansi kwemiphumela eminingi yesendlalelo sekhava ye-acoustic, i-Helmholtz resonator, umkhumbi-mkhathi, isudu yasemkhathini, njll., umsindo ongaphakathi kwe-fairing ulawulwe ngempumelelo, nempilo yokuzwa yosomkhathi iqinisekiswe ngokuthembekile.
