Ubume be-Boeing 757-200

I-Airliner Boeing 757-200 yiyona nto iguqulwa ngokuqhelekileyo yendiza yoluhlu lwe-757. Ngokuxhomekeke kwindlela yokucwangcisa, iyakwazi ukuthwala abagibeli abangama-200 ukuya kuma-228 ngexesha elinye. Okwangoku, iinqanawa zisetyenziselwa ngokuthe ngqo kwiindlela ezihamba phambili phakathi kweenqwelo zeenqwelo-moya ezijikelezayo kwihlabathi kwaye ngokufanelekileyo ziqwalaselwe ngenye yeeprojekthi eziphumelele kakhulu kulo mvelisi waseMerika kwimbali yobukho balo.

Imbali emfutshane

Kwiminyaka engamashumi asixhenxe ekhulwini lokugqibela kwakukho ingxaki yamandla eyaziwayo emhlabeni, eyakhokelela ekunyuseni ngokukhawuleza kwintengo yamafutha. Kule nkalo, uqoqosho lweenqwelo-moya lube yinto ephambili ephambili ekuphuhliseni umzekelo omtsha. Ngokuphathelele ekuqaleni koyilo lwaye lwaziwa ngowe-1977. Emva koko inketho ye-airliner eyenzelwe abagibeli abayi-136 yaqwalaselwa. Kamva umthamo unyuke ngowokuqala ukuya kwi-160, kwaye emva kwezi-189 izihlalo. Abathengi bokuqala bemodeli baseBritish Airways kunye ne-Eastern Airlines. NgoFebhuwari 19, 1982 esibhakabhakeni kwavela i-Boeing 757-200. Iingcaphephe zengcali ziye zatshengisa ulwazi olugqwesileyo lwemoto ngokwemigangatho yokusebenza kakuhle, iimpawu zokhuseleko kunye neendiza. Ngaloo nto, akumangalisi ukuba i-innovative yaphumelela ngokukhawuleza iimvavanyo kwaye yafumana izatifikethi ezifanelekileyo, emva koko i-serial production yayo yaqala. I-liner yaveliswa ngo-2004.

Iimpawu eziphambili

Imodeli ifakwe iinjini ze- turbojet. Kule meko, abaqulunqi bembali kwimbali yobukho balo bafaka iiyunithi zamandla eziveliswa nguRolls-Royce noPratt Whitney. Ukusetyenziswa kobunzima be-avionics ye-EFIS yedijithali, equka iinkcukacha ezibalaseleyo ezibalaseleyo ezibonisa ukubonisa lonke ulwazi olufunekayo lwendiza, lubaluleke kakhulu. Ubude be-Boeing 757-200 buyi-mitha ezingama-38, kwaye ububanzi obubanzi befuselage bubungama-3.76 amitha. Ijubane lokuhamba ngeenqanawa elingu-935 km / h, kwaye isitya sayo sokusebenza sisetyenziswe kwiimitha ezili-12800. Ngenxa yokufumaneka kweendawo zokugcina amagesi, umqhubi womoya uya kukwazi ukukhawulela umgama weekhilomitha ezingama-7 240. Ubuninzi bokukhutshwa kweenqwelo-moya ziyi-115.6 toni, kunye nokuhlaliswa nokukhutshwa, ubude bemizuzu engama-2230 ubude bufunekayo.

Iskimu

Umgangatho wolu hlobo lweBoinging 757-200 layout layout luquka ulwahlulo lwayo kwindawo yokuqala, ishishini kunye nezoqoqosho. Ingqikithi, inemiqolo engama-40, nganye leyo iqulethwe izihlalo ezithandathu, ezisekhohlo kunye nezithathu ezisekhohlo. Oku kunika ilungiselelo elihle kakhulu labagibeli. Ngaphambi kokuba izihlalo zomqolo wokuqala zifumane izindlu zangasese, ngokubhekiselele kuyo into engcono kakhulu abangayi kubizwa ngayo. Ngakolunye uhlangothi, abantu abahleli apha banethuba lokubeka imilenze yabo ngokufanelekileyo. Ngomqolo wesibini, udonga lwegumbi lokucoceka liphantse ngokuthe ngqo. Abahambi abanamava bayacetyiswa ukuba bangathengi itekiti kwinqanaba leshumi kubantu abajongene neengxaki zangemuva, njengoko iindawo ezingasemva kwezihlalo apha azihlali phantsi ngenxa yokuphuthuma kwexesha eliphuthumayo.

Iindawo ezilungileyo nezimbi

Ngokuxhomekeka kwi-cabin ye-airline Boeing 757-200 inako ukufumana abagibeli abayi-200 ukuya kuma-239. Iindawo ezifanelekileyo, ukusuka kwindawo yokujonga nganye, zingahluka. Ngokukodwa, abanye abantu bayakuqonda ukufikelela kwimeko yokuphuthuma, okwesibini - bakhetha izihlalo ezizilungeleyo nezizilungeleyo, okwesithathu - bafuna ukubona amaninzi amalungiselelo enkunkuma. Ukuba sithetha ngokhuseleko, ngoko iingcamango eziphantse zonke iingcali ziyavuma ukuba iindawo eziphambili kweli cwangciso zifumaneka kwicandelo lomsila. Njengoko kuboniswa ngabahloli bahamba, kukulungele ukunyuka ngomqolo wama-32. Inyaniso kukuba iminyango yeendawo zihlala apha, kwaye izindlu zangasese zide kakhulu. Musa ukulibala ngeklasi yoshishini, apho abagibeli banikwa iinkonzo ezininzi ezongezelelweyo.

Kukho i-Boeing 757-200 kwiplanethi kwaye ayikho izihlalo ezikhululekile. Ngokutsho kokuphononongwa kwabakhenkethi, ngomgca weshumi elinesibini ngenxa yesizathu esithile kuhlala kubanda, kwaye ngo-yeshumi elinesibini - akukho festile, ngoko akunakukhathazeka. Ezinye iziphazamiso zenzeka kubagibeli ukusuka kumashumi amathathu namatye. Inyaniso kukuba izihlalo ezikuzo azihlali. Ngaphezu koko, kungekude, ngokulandelanayo, yindlu yangasese kunye negumbi lobuchwepheshe.

Ntlekele

Ukususela kwimingcipheko kunye neengozi ezingaqinisekwanga naliphi na indiza. Imbali ye-Boeing 757-200 imodeli ine-eight crash ercraft, nto encinane kakhulu xa kuthelekiswa nezinye iindiza. Ukongezelela koko, kwiimeko ezininzi, le ntlekele ayizange ivele ngenxa yokungasebenzi kakubi kwezobugcisa okanye i-crew error, kodwa ngenxa yezenzo zamaphekula. Ngokomzekelo, ngo-2001, iinqaba ezimbini zamatye eNew York zatshatyalaliswa ngenxa yokuba i-liner yale nguquko yaphazamiseka kubo.

Kungakhathaliseki ukuba yintoni, ngokuqhelekileyo, imoto ithathwa njengenye yeenqwelo ezinamandla kunye ezinokuthenjwa ngokukhuseleko. Iyakuboniswa kwiinkqubo zokubonelela ngezobugcisa, inzantya ephantsi kunye nezinga eliphezulu lokuthuthuzela abantu, nangona ukuba imodeli yashiywa ngaphezu kweminyaka elishumi edlulileyo. Olu dumela lingaziqhayisa ngelo lonke iinqwelo-moya ezakhiwe namhlanje.
