Pūkaha Turboprop: he pūrere, te ara iahiko mahi parau tumu. engines Production turboprop i Russia

Engine turboprop rite te kōkeke: a ia me te tahi atu i te hurirere. Ko te kore e rerekē ratou. Fakakaukau ki he me'a tikanga tenei kōwae, me pehea te mahi i te reira, he aha e ona pai me ngā raruraru.

āhuatanga General

no engine Turboprop ki te piha haapiiraa o kapohau hau e kua hangaia rite transducers pūngao ao, me te kua whakamahia whānuitia i roto i te rererangi. ngā ratou o te pūkaha wera, huri ai nga haurehu whakawhānui te mīhini huri hiko, me te hanga i te taipana, a ki tona take piri atu wae. whakaratohia te pūkaha e ki te hurirere turboprop.

Ko te ripeka i waenganui i te kōkeke, me te matangirua wae. Tuatahi, i roto i te pūkaha rererangi kōkeke tāuta, arā, o te porotakaroa ki te whetu-āhua whakarite roto te take. Otiia e tika ana ki te meka e rawa nui rahi me te taimaha, pera me te pea o te tere iti a ratou, e kore whakamahia e ratou, ka puta hoatu manakohanga tautuhinga turbojet. Otiia kihai i enei engines kahore drawbacks. Ka taea e ratou te whakawhanake i tētahi tere paorangi, engari pau te rota o te wahie. Na reira ko te utu rawa hoki waka pāhihi ratou mahi.

i Engine turboprop ki akakoromaki i te ngoikoretanga taua. Na kua tenei raruraru kua faatiti'aifarohia. tangohia Construction me te mahi i i te huarahi o te pūkaha turbojet, me i te kōkeke - propellers. Ko te kupu, ka reira huinga taea rahi iti, utu, me te tiketike o te tōtika.

Ko te engines whakaaro i a hanga hoki i roto i te thirties o te rau tau whakamutunga i roto i te Soviet Union, me rua tekau tau i muri mai, ka anga ratou ki te production papatipu. I rerekē Power i 1880 ki te 11000 Kw. Te wā roa i whakamahia ratou i roto i te rererangi hōia, me te tivira. Heoi, tere paorangi, kihai i uru ratou. Na reira, kihai ratou ki te haerenga mai o taua whakaurunga i roto i te Air Force. Ko rererangi haukāinga, te nuinga tukua e ratou.

pūkaha taputapu turboprop me tona parau tumu mahi

Ko te tino māmā hoahoa nekeneke. Kei roto te reira i:

• reducer;
• hurirere;
• he ruma ngingiha;
• he compressor;
• pupuha.

turboprop Aronui e whai ake: i muri i te werohanga me kōpeketanga o te rangi i te compressor tomo te ruma ngingiha. i patia tukunga wahie. mura te ranunga hua kei te ka hanga haurehu e tomo te mīhini huri hiko hōrapatanga, tītaka reira, a reira, i roto i tahuri, tītaka te compressor me takahuri. tukua pūngao kïhei te i roto i te pupuha, te hanga aki urupare. No te mea e kore te mea nui (tekau ōrau) tona utu, e kore te reira e whakaaro he turboprop turbojet.

Ko te parau tumu o te mahi me te hoahoa, Heoi, he rite ki a ratou, otiia kahore he te pūngao tino i roto i roto i te pupuha, te hanga i te ringa tauhohe taipana, engari wāhanga anake, kia rite ki te pūngao whai hua ko ano hoki huri te tīwiri.

take whakahaere

He engines ki tetahi e rua ranei ngahaú. Ko te kē kotahi-take i runga i tetahi take, me te compressor me te mīhini huri hiko, me te tīwiri. I roto i te take-rua - eke tetahi o ratou mīhini huri hiko, me te compressor, a ki runga ki te tahi atu - te tīwiri i roto i te taputapu whakaiti. Here i reira e rua kapohau hono ki tetahi tetahi tikanga hau-hihiri. Ko tētahi o ratou ko mo te tīwiri, me te tahi atu - mo te compressor. Ko te nuinga noa he whakatinanatanga taua, mai taea te tono i te pūngao i waho rere i te tīwiri. He tino pai tenei ina ko te waka rererangi i runga i te whenua.

compressor

Kei tēnei wāhanga o rua ki te ono ngā wāhanga, tuku ki te kite nui huringa i roto i te pāmahana me te pēhanga, me te ki te whakaiti i te tere. Ki tenei hoahoa, huri i te reira i roto i ki te whakaiti i te taimaha me te rahi, i te mea tino nui mō te engines rererangi. Ko te compressor ngā impellers me vanes aratohu. I runga i te whakamutunga kia whakaratohia ai ranei e kore e whakaratohia ture.

hurirere

Ngā mihi ki tenei taipitopito i hanga te aki, engari he iti te tere. Kei te whakaaro te reira i te tohu pai o te taumata o 750 ki te 1500 rpm, mai i te whakanui ake i te tōtika tīmata ki te hinga, me te titaria hei utu takahuri kia tahuri ki te wahia. huaina te tītohunga ko te "pānga o kati." Kei te meinga te reira e te matatahi takahuri i ka kīia e tiketike i roto i te hurihanga, nui rawa te tere o te oro, timata ki te mahi tika. Ka te taua pānga kia kitea ki te hua i roto i to ratou diameter.

mīhini huri hiko

Ko te mīhini huri hiko e taea ki te whakawhanake i te tere o runga ki te rua tekau mano huringa i te meneti, engari e kore e taea taringa, te reira pai, pera i konei i reira ko te taputapu whakaiti e whakaiti tere, me te whakanuia ana taipana. Ka taea e Gearboxes kia rerekē, engari ratou mahi matua ahakoa o te momo - pōturi iho, ka whakapiki ake i te wa.

E whakaiti ana tēnei āhuatanga i te whakamahinga o te rererangi turboprop hōia. Heoi, e kore e whanaketanga i runga i te hanganga o te nekeneke paorangi mutu, i te iti rawa hoki inaianei me he kahore angitu. Hei whakapai ake i te pamu ētahi wā whakaratohia e rua pokekore te ki te turboprop. Parau tumu o te mahi i te wa ano i mohio ratou e hurihuri i roto i ngā tohutohu ritenga, engari ki te taputapu kotahi.

Ka rite ki te tauira, whakaaro te pūkaha D-27 (Turbopropfan) he rua tahi helical piri ki te tōnā mīhini huri hiko noa. Ko anake te tauira o te hoahoa whakamahia i roto i te rererangi tenei. Ko whakaaro tona tono angitu te he tupeke nui ki te whakapai ake i te mahi o te pūkaha pūrongo.

Huapai me ngā huakore

wehea tatou i nga pluses me minuses e kua āhuatanga te mahi o te turboprop. Ko nga painga e:

• taimaha marama he mea whakarite ki nga wae kōkeke;
• kakama whakaritea ki engines turbojet (e tika ana ki te tōtika hurirere tae waru tekau-ono ōrau).

Heoi, ahakoa enei painga whakakorekore, engines jet, i roto i ētahi wā e ake pai. Turboprop rohe tere pūkaha ko e whitu rau e rima tekau kiromita ia haora. Heoi, no te rererangi hou o te ruarua rawa. I tua atu, i te reo i hanga he tiketike rawa, rawa te uara tīkina o te International Civil Aviation Organization.

Na reira, he iti te hanga o engines turboprop i Russia. Fele, kua tāuta ratou i roto i te waka rererangi e rere tawhiti te roa, me te i te tere iti. Na ka ko tika te tono.

Heoi, i roto i te rererangi hōia, te wahi i nga āhuatanga matua e hiahiatia ana o te rererangi e huri mai tiketike, me te mahi ata, kaua ki te pai, e kore e whakatau i enei engines nga whakaritenga e tika ana, me te e whakamahia wae turbojet konei.

I te wa ano e te whakawhanakehia tonu tatou ki te hanga i tētahi pokekore paorangi ki te hinga i te "ārai pānga" ka tae te taumata hou. Pea, ka te tenenga ko ki te riro i te mooni, i engines jet e pai ki te turboprops me te rererangi hōia. Otiia i te kau e taea anake te whakaahuatia ratou rite "workhorses" e kore e te tino kaha, engari te mahi pūmau.
