Ngokusebenzisa isakhiwo sezinto ezidityanisiweyo zefayibha yekhabhoni, irokhethi ethi “Neutron” iya kuba sisithuthi sokuqala esikhulu emhlabeni sokuqalisa izinto ezidityanisiweyo zefayibha yekhabhoni.
Ngokusekelwe kumava angaphambili aphumeleleyo ekuphuhlisweni kwesithuthi esincinci sokuqalisa i-“Electron”, iRocket Lab USA, inkampani ephambili yase-US yokuqalisa kunye nenkqubo yesithuba, iphuhlise ukuqaliswa okukhulu okubizwa ngokuba yi-“Neutron” Rockets, enomthamo womthwalo weetoni ezisi-8, ingasetyenziselwa ukuhamba esibhakabhakeni okunabantu, ukuqaliswa kweenkwenkwezi ezinkulu zesathelayithi, kunye nokuhlola isithuba nzulu. Irokhethi ifumene iziphumo eziphambili kuyilo, izixhobo kunye nokusetyenziswa kwakhona.
Irokhethi ethi “Neutron” luhlobo olutsha lwesithuthi sokuqalisa esinokuthembeka okuphezulu, esinokusetyenziswa kwakhona kwaye sixabisa kancinci. Ngokungafaniyo neerokhethi zemveli, irokhethi ethi “Neutron” iya kuphuhliswa ngokweemfuno zabathengi. Kuqikelelwa ukuba ngaphezulu kwe-80% yeesathelayithi eziza kuqaliswa kwiminyaka elishumi ezayo ziya kuba zii-constellations zesathelayithi, ezineemfuno ezikhethekileyo zokusasazwa. Irokhethi ethi “Neutron” inokuhlangabezana ngqo neemfuno ezinjalo ezikhethekileyo. Isithuthi sokuqalisa esithi “Neutron” senze olu phuhliso lobuchwepheshe lulandelayo:
1. Isithuthi sokuqala esikhulu sokuqalisa emhlabeni esisebenzisa izinto ezidityanisiweyo ze-carbon fiber
Irokhethi ethi “Neutron” iza kuba sisithuthi sokuqala esikhulu sokuqalisa emhlabeni esisebenzisa izinto ezidityanisiweyo ze-carbon fiber. Irokhethi iza kusebenzisa izinto ezintsha nezikhethekileyo ze-carbon fiber composite, ezinobunzima obuphantsi, ezinamandla aphezulu, ezinokumelana nobushushu obukhulu kunye nempembelelo yokuqalisa nokubuyela kwakhona, ukuze inqanaba lokuqala lisetyenziswe ngokuphindaphindiweyo. Ukuze kufezekiswe ukuveliswa ngokukhawuleza, isakhiwo se-carbon fiber composite serokhethi ethi “Neutron” siya kuveliswa kusetyenziswa inkqubo yokubeka i-automatic fiber (AFP), enokuvelisa igobolondo le-carbon fiber composite rocket elinobude obuziimitha ezininzi kwimizuzu embalwa.
2. Isakhiwo esitsha sesiseko senza kube lula inkqubo yokuqalisa kunye nokufika
Ukuphinda kusetyenziswe yeyona nto iphambili ekuqaliseni rhoqo nangokungabizi kakhulu, ngoko ke ukususela ekuqaleni koyilo, irokhethi ye-"Neutron" yanikwa amandla okufika emhlabeni, ukubuyisela kwakhona nokuqalisa kwakhona. Ukujonga kwimo yerokhethi ye-"Neutron", uyilo olunciphileyo kunye nesiseko esikhulu nesiqinileyo asigcini nje ngokwenza lula ulwakhiwo oluntsonkothileyo lwerokhethi, kodwa sikwasusa nesidingo semilenze yokufika kunye neziseko zesiza sokuqalisa esikhulu. Irokhethi ye-"Neutron" ayixhomekekanga kwinqaba yokuqalisa, kwaye inokuqalisa imisebenzi kuphela kwisiseko sayo. Emva kokuqalisa kwi-orbit nokukhulula irokhethi yesigaba sesibini kunye nomthwalo wayo, irokhethi yesigaba sokuqala iya kubuyela emhlabeni kwaye ifike kancinci kwindawo yokuqalisa.
3. Ingcamango entsha yefairing iphula uyilo oluqhelekileyo
Uyilo olukhethekileyo lwerokethi ethi “Neutron” lukwabonakala kwirokethi ebizwa ngokuba yi “Hungry Hippo” (Hungry Hippo). Irokethi ethi “Hungry Hippo” iya kuba yinxalenye yesigaba sokuqala serokethi kwaye iya kuhlanganiswa ngokupheleleyo nesigaba sokuqala; irokethi ethi “Hungry Hippo” ayiyi kwahlulwa kwirokethi ize iwele elwandle njengerokethi yendabuko, kodwa iya kuvulwa njengemvubu. Umlomo uvuleka ukuze kukhululwe isigaba sesibini serokethi kunye nomthwalo wokuhlawula, ize ivalwe kwakhona ize ibuyiselwe eMhlabeni ngerokethi yesigaba sokuqala. Indawo yokufika kwerokethi kwindawo yokuqalisa yirokethi yesigaba sokuqala enerokethi, enokuhlanganiswa kwirokethi yesigaba sesibini ngexesha elifutshane ize ivulwe kwakhona. Ukwamkela uyilo lwerokethi ethi “Hungry Hippo” kunokukhawulezisa isantya sokuqalisa kwaye kupheliswe iindleko eziphezulu kunye nokuthembeka okuphantsi kwerokethi yokuphinda isetyenziswe elwandle.
4. Isigaba sesibini serokethi sineempawu eziphezulu zokusebenza
Ngenxa yoyilo lwe-fairing ye-"Hungry Hippo", inqanaba lesi-2 le-rocket liza kuvalwa ngokupheleleyo kwi-rocket stage kunye ne-fairing xa iqaliswa. Ke ngoko, inqanaba lesibini le-rocket ye-"Neutron" liza kuba lelona nqanaba lesibini likhaphukhaphu kwimbali. Ngokubanzi, inqanaba lesibini le-rocket liyinxalenye yesakhiwo sangaphandle sesithuthi sokuqalisa, esiya kuvezwa kwindawo engqongileyo engqongqo yomoya ophantsi ngexesha lokuqaliswa. Ngokufaka inqanaba le-rocket kunye ne-"Hungry Hippo" fairing, inqanaba lesibini le-rocket ye-"Neutron" alifuneki. Ukumelana noxinzelelo lwendawo yokuqalisa, kwaye kunokunciphisa kakhulu ubunzima, ngaloo ndlela kufezekiswa ukusebenza okuphezulu kwendawo. Okwangoku, inqanaba lesibini le-rocket lisalungiselelwe ukusetyenziswa kube kanye.
5. Iinjini zerokethi ezakhelwe ukuthembeka nokusetyenziswa ngokuphindaphindiweyo
Irokhethi ethi “Neutron” iza kusetyenziswa yinjini entsha yerokhethi ethi Archimedes. I-Archimedes iyilwe kwaye yenziwe yiRocket Lab. Yinjini ye-liquid oxygen/methane gas generator cycle enokusetyenziswa kwakhona enokubonelela nge-1 meganewton ye-thrust kunye nemizuzwana engama-320 ye-initial specific impulse (ISP). Irokhethi ethi “Neutron” isebenzisa iinjini ezi-7 ze-Archimedes kwinqanaba lokuqala, kunye ne-vacuum version enye yeenjini ze-Archimedes kwinqanaba lesibini. Irokhethi ethi “Neutron” isebenzisa iindawo zesakhiwo ezidityanisiweyo ze-carbon fiber, kwaye akukho mfuneko yokufuna ukuba injini ye-Archimedes ibe nokusebenza okuphezulu kakhulu kunye nobunzima. Ngokuphuhlisa injini elula kakhulu enokusebenza okuphakathi, ixesha lophuhliso kunye novavanyo linokufutshane kakhulu.
