Ina kōrero tātou mō te ao rererangi, ko te mea e puta ake ana ki te hinengaro ko ngā rōkete kaha, ngā waka rererangi whawhai e rere ana, ngā kairangi rererangi rānei e hikoi ana i te wāhi. Engari, kāore pea koe e mōhio kei muri i ēnei taputapu hou, he mahi nui tā te paura parauri iti –alumina parauri kua whakaranuapaura moroiti. Tērā pea he iti te ahua o te ingoa, engari kaua e whakaititia. Ko te alumina parauri he momo mea e kiia nei e tātou ko te "emery," he pakeke ake i te taimana, engari he utu iti ake. I ngā tau o mua, i whakamahia whānuitia mō te huri i ngā konganuku i runga i ngā wira huri me te pepa kirikiri, hei mahi nui i roto i te ao ahumahi. Engari kei te whai wāhi nui tēnei rauemi māmā, kāore hoki i te tino pai ki te wāhanga "hangarau teitei" o te rererangi.
He Huringa Whakamiharo mai i te "Grindstone" ki te "Paruru Tiaki"
Ko ngā rauemi rererangi te mea nui ki te "māmā" me te "kaha." Me māmā ngā parirau kia rere teitei ake, kia tawhiti atu; me kaha te tinana o te waka rererangi kia tu atu i te makariri rawa i ngā teitei, te waku kaha ina pakaru te arai oro, me ngā pāmahana whakamataku i roto i te miihini. Nā tēnei ka nui ngā tono mō te mata o te rauemi. Koinei te wāhi epaura moroiti alumina parauri kua hanumika tae mai. I kitea e ngā miihini mā te whakamahi i te hangarau rehu tere-teitei hei "whakapiri matao" i tēnei paura moroiti ki ngā wāhanga nui pēnei i ngā mata o te tāwhana me ngā pakitara o te rūma mura, ka taea e rātou te hanga i tētahi "pūeru uku" he angiangi ake i te maikuku engari he tino kaha. Ahakoa tōna angiangi, ka roa ake te roa o te ora o ngā mata o tēnei paparanga tiaki i raro i te horoinga o te hau pāmahana teitei 1600-tohu Celsius. "He rite ki te hoatu i tētahi 'koti ārai matā' ki te ngākau o te miihini," te whakamārama a tētahi miihini tawhito kua mahi i roto i tētahi wheketere miihini mō ngā tau e rua tekau. "I mua, me whakakapi ngā mata i muri i tētahi wā whakamahinga, engari ināianei ka roa ake te ora, ka whakapai ake i te pono me te whai huatanga ōhanga o te waka rererangi."
Ngā tono whānui, mai i te rangi ki te whenua
Ehara i te mea ko ngā miihini anake ngā kaha o te paura moroiti alumina parauri kua hanumi.
Me tīmata tātou ki ngā waka rererangi. He nui te whakamahinga o ngā rauemi hiato o ngā waka rererangi me ngā waka rererangi whawhai o ēnei rā, pērā i te muka waro. He mama, he kaha hoki tēnei rauemi, engari he ngoikoretanga: ko ngā wāhi e honoa ai ngā rauemi rerekē ka ngāwari ki te wehewehe. Ko te otinga? I mua i te hononga, ka "whakapakari" ngā mata hononga mā te whakamahi i te paru hau-whakakākā pēhanga teitei kei roto ko te paura moroiti alumina parauri kua whakakotahihia. Ehara i te mea he whakapakari noa iho tēnei; ka hangaia he maha ngā pūwāhi punga i te taumata moroiti, ka taea ai e te piripiri te "mau" kaha ake. Ka whakapai ake tēnei maimoatanga i te ātete ngenge o te hononga parirau-ki-te-tinana mā te neke atu i te 30%.
Whakaarohia te ao rererangi. Ina whiti ngā rōkete i te hau, ka pāngia te ihu o te koeko me ngā taha o mua o te parirau e te whakamātautau o te "whakangaromanga ahi." I konei, ka kitea te uara o te paura moroiti alumina parauri i tētahi atu huarahi - ka whakamahia hei matūriki whakapakari matua i roto i te whakarite i ngā paninga ārai-waikura. Mā te tāpiri atu ki ngā paninga uku motuhake me te rehu atu ki te mata o ngā wāhanga ātete-wera, ka hangaia e tēnei kiriata he paparanga waikura matotoru i ngā pāmahana teitei, ka ārai i te urunga hāora i muri mai, ka tiaki hoki i ngā rauemi o roto mai i te mimiti. Ki te kore, he maha ngā waka rererangi e hoki anō ana ki te hau ka "kore e mōhiotia".
Ka kitea anō hoki tōna aroaro i runga i ngā amiorangi me ngā teihana mokowā. Me mau tonu te mahi pono mō ngā whāriki me ngā wāhanga neke o ētahi taputapu tika i roto i te korehau me ngā pāmahana tino iti o te mokowā. He tino iti te tauwehenga o te waku o ngā whāriki uku kua orohia pai ki te paura moroiti alumina parauri kua whakakotahihia, ā, kāore e puta he para kakahu, ka noho hei "whakapūmau" e whakamana ana i te mahi pumau o ēnei wāhanga mō ngā tau tekau, rua tekau rānei i te āmiomio.
"Ngā Rauemi Tawhito" e Tutuki ana i ngā Wero o te "Mātauranga Hou"
Ae, ko te whakamahi i tēnei "rauemi tawhito" i roto i ngā taiao tino uaua o te rererangi ehara i te mea ngāwari noa iho, pērā i te kawe mai i ngā mea whakakoi mai i te wheketere. He maha ngā mahi uaua kei roto.
Ko te wero nui ko te "parakore" me te "ōrite." Ko te paura moroiti alumina parauri kua whakaranua e hiahiatia ana mōngā tono rererangiMe tino parakore, me tino kore rawa he poke, nā te mea ka taea e tetahi wāhanga kāore e hiahiatia te noho hei tīmatanga mō ngā kapiti i raro i te ahotea nui, i ngā pāmahana teitei rānei. Hei tāpiri, me tino ōrite te rahi me te āhua o te matūriki; ki te kore, ka ngoikore te paninga. "He rite tēnei ki te hanga keke tino pai; ehara i te mea ko ngā kai pai anake e hiahiatia ana, engari me tātarihia te paraoa kia tino pai, kia ōrite hoki," te kī a tētahi miihini whakahaere kounga rauemi. "He tino pakari ake tā mātou tukanga tātari me te purenga i ngā whakaritenga o tētahi kīhini hōtēra rima-whetu."
Hei tāpiritanga, he pūtaiao uaua anō hoki te "whakapiri" i tēnei paura ki ngā wāhanga. Ko te hangarau matatau rawa atu i tēnei wā ko te rehu mura supersonic, e āhei ai ngā matūriki paura moroiti ki te pā ki te papa i ngā wā maha atu i te tere o te oro, ka hua ake he hononga kaha ake, he paninga matotoru ake hoki.
E hiahiatia ana tēnei momo "kaha" mō te heke mai o ngā rangi.
I te whanaketanga o te hangarau rererangi ki ngā rohe teitei ake, tere ake, me tawhiti atu, ka nui haere ngā tono mō ngā rauemi. Ko ngā waka rererangi hypersonic, ko ngā waka mokowhiti ka taea te whakamahi anō, ko ngā waka tirotiro mokowā hohonu… ko ēnei whetu o te heke mai ka whakawhirinaki katoa ki te tiakitanga tino nui.
Te whanaketanga opaura moroiti kōrunuma parauriKei te anga atu hoki ki tētahi huarahi mohio ake, hiato ake. Hei tauira, kei te ngana ngā kaipūtaiao ki te "whakaranu" ki ētahi atu huānga, ki te whakakotahi rānei ki ngā rauemi hou pēnei i te graphene. Ehara i te mea ko te ātete pāmahana teitei anake te whāinga, engari ko te kaha ki te kite mohio i te kino me te whakatika i a ia anō i ētahi pāmahana. Ko te whakatupuranga e whai ake nei o ngā pūnaha tiaki wera aero me te mokowā ka whakamahi pea i tēnei momo paninga "atamai" kua whakapakaritia.
Ko te kōrero mō te paura moroiti parauri korundum he tirohanga poto o ngā rauemi ahumahi Hainamana maha: i whānau mai i ngā takenga iti, engari kei te kitea he tūranga nui mā te whakapai tonu i te hangarau. Ahakoa kāore i te tino kanapa pērā i ngā koranu titanium, kāore hoki i te tino huatau pērā i te muka waro, ko tēnei "kaha" marino kei muri i ngā whakaaturanga e tautoko ana i ngā moemoeā a te tangata ki te rere, ki te pakaru i te rangi, ki te rere ki ngā pito tawhiti o te wāhi hohonu.
Ina titiro tātou ki te rangi whetu, me te hamama mō ia whakarewatanga angitu, tera pea ka mahara tātou kei raro i taua kanapa whakarewa kanapa, he maha ngā matūriki parauri ririki, pumau e whiti puku ana i tō rātou kaha e kore e taea te hinga.
