I-Turbojet injini: uhlelo lokusebenza kanye nedivayisi

Injini ye-turbojet iyinhlangano ye-turbine i-turbine, lapho kuqhutshwa khona ukuguqulwa ngokuguqula amandla (okushisayo) emfudlaneni wegesi kinetic. Ukusabela okuphumela ekusebenziseni kuyisisetshenziswa.

I-turbojet injini ithole ukusatshalaliswa okukhulu nokusebenza kahle emazindizeni e- aircrafts angakwazi ukuthuthukisa isivinini esikhulu sezindiza (indiza ephezulu).

Kukhona amadivaysi owodwa namabili wesifunda, anikezwa ama-backburners, okuvumela kakhulu ukwandisa ukuphuma nokushayela indiza. Kulokhu, nge-index ephezulu, ijubane lendiza landa.

Ububanzi bokusetshenziswa kwezinjini ze-turbojet kubangelwa ukulula okuhambisanayo kokuklama kwawo nokunciphisa okuphansi. Iyunithi iqukethe igumbi lokushisa, i-turbine, i-compressor kanye nombhobho wokukhipha omelela ipayipi yokunciphisa elitholakala ngaphakathi kwe-manifold exhaust.

Umoya uthola ukunyuka kokuqala kwengcindezi (ngenxa yekhanda eliphakeme kakhulu), okuyinto ephakama kwi-compressor. Lokhu kuvumela ukudala izimo ezihle zokucubungula nokusebenzisa kahle ukushisa. Ukushisa okuvumelekile ekungeneni kwe-turbine yegesi kuncike ekumeni ukushisa kwezinto zokwakha kanye nokusebenza kahle kwe-turbine. Ukwanda komshini womoya nokushisa kwegesi kuyisici sokwehluka kwenhlobo yama-turbine amadivayisi.

Injini ye-turbojet, esetshenziselwa ukuhamba kwezindiza engapheli futhi ephakeme, inikeza ukunyuka okuphawulekayo ekugxilweni kwamamodi wokubuyisela emuva, futhi ngenxa yalokho, amandla okubamba lapho isivinini se-supersonic sifike khona. Kodwa-ke, ama-aggregates asetshenziselwa izindiza zezindiza, ngamapharamitha okulandelana kanye nomnotho, aphansi kunezinye izinhlobo zama-turbine injini. Lokhu kungenxa yesimiso sedivaysi, ehambisana nokulahlekelwa okushisa kakhulu nokushisa okusheshayo nge-jet exhaust ezinombolo zezindiza eziphansi (M).

Injini ye-turbojet ayikwazi ukuhlanganiswa ngezandla zayo, ngoba lokhu kuyadingeka ukwazi kahle isakhiwo sayo kanye nemigomo yokusebenza kwazo zonke izici.

Le divayisi ihlanganisa uhlelo lwe- compressor gas, oluphakathi kwamakamelo nendawo yokungena. Ngenxa yamandla avela ekushiseni kwamafutha, i-turbine idonsa i-compressor futhi ihlinzeke ngokulandelana.

Izikimu eziningiliziwe nezibalo zezingxenye zesistimu yokuqhuma, kanye ne-piston motors, zihluke kakhulu. Emithonjeni ehlukahlukene, ungathola idatha enemininingwane yokubala kanye nezincazelo ezilula zalezi zinhlelo, okukuvumela ukuba wenze injini ye-turbojet eyenziwe ngokwakho.

Izinyathelo lapho amaphampu we-centrifugal efakiwe ayinayo i-afterburner. AmaGesi, eshiya i-turbine, angena emzimbeni we-jet, emva kwalokho aphelelwa emkhathini ngesivinini esikhulu. I-thrust idalwe ngokunyusa ukuvinjelwa kwamagesi okushiya injini.
