Te Mahi a te Rotor i roto i te Pūkaha Hau
Ko ngā kōrero mō te pūngao hou ka aro nui ki ngā tāpine hau. Kua roa te mōhiotia o ngā tāpine hau he taputapu whai hua mō te huri i te pūngao hau ki te hiko. Ko tētahi o ngā wāhanga tino nui o te tāpine hau ko te rotor. Ka matapakihia e tēnei tuhinga te mahi a te rotor i roto i te tāpine hau, me te whanaketanga me te mahi o tēnei hangarau.
He Kupu Whakataki ki ngā Tāhū Hau
He taputapu te tāpine hau e huri ana i te pūngao nekeneke o te hau hei pūngao miihini, kātahi hei pūngao hiko. I te nuinga o te wā, he maha ngā wāhanga matua o te tāpine hau, tae atu ki te rotor, te nacelle (whare tuku), te pourewa, me te turanga. I roto i ēnei wāhanga, e kiia ana te rotor ko te "ngākau" o te tāpine hau.
He aha te rotor?
Ko te rotor te wāhanga o te tāwhana hau e hopu ana i te pūngao hau, ā, ka huri hei pūngao miihini. He maha ngā wāhanga o te rotor, tae atu ki ngā mata, he pokapū (pokapū rotor), me te pou. I te nuinga o ngā hoahoa tāwhana hau hou, e rua, e toru rānei ngā mata o te rotor. He mea hanga ēnei mata ki ngā rauemi mama, kaha pērā i te muka karāhe, te muka waro rānei hei whakanui ake i te whai huatanga o te pūngao me te roa o te ora.
Te Mahi Matua o te Rotor
1. Te Tahuri i te Pūngao Kinetic o te Hau
Ko te mahi matua a te rotor he huri i te pūngao nekeneke o te hau hei pūngao miihini e taea ai te whakamahi. Ina pupuhi te hau, ka hopukina e ngā mata o te rotor tēnei pūngao, ka huri te rotor. Ko te tere o te hurihanga o te rotor e whakawhirinaki ana ki te tere o te hau me te hoahoa o ngā mata tonu.
2. Ka whakarato i te taipana
Ko te taipana he ine i te nui o te kaha e huri ai te rotor. Ki te kore he taipana e ranea ana, kāore e taea te huri i te kaha nekeneke o te hau hei kaha miihini. He mea nui te hoahoa o te mata o te rotor hei whakatau i te nui o te taipana ka puta. Kua hangaia te rotor kia taea ai e te hau te huri i ngā mata me te kaha nui me te ātete iti.
3. Te Whakataurite i te Utaina
Ko tētahi atu mahi nui ko te taurite i te kawenga. Ka whakaputahia hoki e te rotor hurihuri ngā kaha taha me ngā ahotea hurihuri me taurite kia kore ai e pakaru te hanganga o te tāpine. Me whakarite e te hoahoa rotor ka taea te whakahaere haumaru i ēnei kaha katoa.
Hangarau me te Hoahoa Rotor
Kua tino whanake te hangarau me te hoahoa o te rotor i roto i ngā tau hei whakapai ake i te whai huatanga me te roa o te wā. Ko ētahi o ngā hangarau e whakamahia ana i tēnei wā ko:
Hoahoa Porowhita
– Kōtaha Āhuarangi: Kua hangaia te poroporo me te kōtaha ārangi e rite ana ki te parirau o te waka rererangi hei whakanui ake i te hiki me te whakaiti i te tō.
– Rauemi: He mea hanga te porotiti mai i ngā rauemi hiato pērā i te muka karāhe, te muka waro rānei, he kaha, he māmā hoki.
Pūnaha Whakahaere
– Mana Whakatakoto: Mā tēnei tikanga ka taea te whakarerekē aunoa i te koki o te poroporo kia rite ki te tere o te hau hei whakanui ake i te whai huatanga o te pūngao.
– Mana Whakahīhī: Ka whakahaere tēnei pūnaha i te aronga o te huripokitia e pā ana ki te ahunga o te hau kia pai ai te anga o ngā poroporo ki te hau e pā mai ana.
Ngā Whakapaitanga Āhuarangi
– Parirau iti: Ko ētahi hoahoa rotor hou e whakamahi ana i ngā parāu iti ki ngā pito o ngā mata hei whakaiti i te ngaronga pūngao nā te hanganga awhiowhio.
Te Whai Hua o te Rotor i te Whakaputa Pūngao
Ko te whai huatanga o te pūngao o te tāpine hau e whakawhirinaki nui ana ki te hoahoa me te mahi a tōna rotor. Ko tēnei whai huatanga ka whakaatuhia i te nuinga o te wā hei tauwehenga mana, arā, ko te ōwehenga o te pūngao i whakaputaina e te rotor ki te pūngao katoa o te hau e pā ana ki a ia. Ka taea e te rotor kua hoahoatia pai te whakatutuki i te tauwehenga mana tata ki te 40-50%, e tata ana ki te rohe ariā o te Ture a Betz, arā, 59.3%.
Te Pono me te Tiaki
Ko te rotor tētahi o ngā wāhanga e tino pāngia ana e te ahotea ā-pūkaha i roto i te tāpine hau. Nō reira, he mea nui te tiaki me te tirotiro auau kia mau tonu ai te mahi pai. Kei roto i te tiaki ko te tirotiro ā-tinana i ngā mata mō ngā pakaru, ngā pakaru rānei, me te tirotiro i ngā tikanga pitch me yaw kia tika ai te mahi.
Ngā Wero me te Ao o Muri Mai
Ko tētahi o ngā wero matua o te hoahoa rotor ko te wikitoria i ngā kawenga tauhou i puta mai i ngā hau pūmau koretake, i te haruru rānei e puta mai ana i te rotor e hurihuri ana. Ko ngā mahi rangahau me te whanaketanga o nāianei e arotahi ana ki ngā huarahi hei whakaiti i te haruru me te whakanui ake i te ātete ki ngā āhuatanga huarere kino.
– Te Whakaiti Haruru: Mā ngā tikanga pēnei i te whakamahinga o ngā rauemi mimiti haruru me ngā whakarerekētanga ki te hoahoa o te poroporo ka āwhina i te whakaiti i te haruru e puta mai ana.
– Ātete Rauemi: E arotahi ana hoki ngā rangahau ki te whakawhanake i ngā rauemi hou e ātete ake ana ki te waikura me te kakahu ā-mīhini.
Whakamutunga
He wāhanga nui te rotor i roto i te tāwhana hau, he mahi nui tāna ki te huri i te kaha hau hei kaha whakamahi. Mā ngā hoahoa e whanake tonu ana, mai i ngā mata hauhautanga ki ngā pūnaha whakahaere matatau, ka mahi te rotor ki te whakapai ake i te whai huatanga me te pono o ngā tāwhana hau. Mā te māramatanga hohonu ki te mahi me te hangarau o te rotor, ehara i te mea ka āwhina i te hoahoa pai ake, engari ka whakarite hoki i te pumau me te whakatinanatanga angitu o te kaha whakahou mā roto i ngā tāwhana hau. Mā ngā whakapainga tonu i roto i te hangarau rotor ka whakarite kia noho tonu ngā tāwhana hau hei pou matua ki te whakatutuki i te hiahia o te ao mō te kaha ma, pumau ake hoki ā muri ake nei.
