Ntxuam kuj hu ua "turbofan engine".Nws yog hais txog lub cav roj turbine uas cov roj txhaj los ntawm lub nozzle thiab cov cua tawm los ntawm tus kiv cua tsim cov tshuaj tiv thaiv thrust.Nws muaj xws li compressor, combustion chamber, high-pressure turbine (tsav lub compressor), ib tug low-pressure turbine (tsav ib tug kiv cua) thiab ib tug pa system.Thawj peb ntu yog hu ua "core engine".Lub zog muaj nyob rau hauv cov roj ntws tawm ntawm lub tshuab tseem ceeb yog siv los tsav lub tshuab hluav taws xob qis kom tsav lub kiv cua, thiab lwm qhov yog siv hauv lub nozzle kom nrawm cov roj ejected.Lub bypass ratio yog ze ze rau kev siv roj.Thawj tiam ntawm turbofan xyaw uas tshwm sim nyob rau hauv lub lig 1950s muaj kuj tsawg bypass piv, compressor boost piv thiab roj kub ua ntej lub turbine.

Tus qauv ntawm FAN yog qhov tseeb tias muaj 1-2 lub zog qis (tsawg-ceev) turbines ntxiv rau tom qab ntawm lub cav turbojet.Cov turbines no tsav qee tus kiv cua thiab haus ib feem ntawm cov pa roj kinetic zog ntawm lub cav turbojet (tub ntxhais lub cav)., Li no ntxiv txo cov pa tawm ceev.Ib feem ntawm cov huab cua ntws los ntawm tus kiv cua yog xa mus rau lub compressor (lub sij hawm "internal duct" nyob rau hauv terminology), ib yam li ib tug zoo tib yam lub dav hlau cav, thiab lwm yam yog ncaj qha tawm ntawm lub periphery ntawm lub turbojet engine casing ("sab nraum. cev”).Yog li ntawd, cov roj hluav taws xob ntawm lub cav turbofan tau muab faib rau ob lub pa cua ntws tawm los ntawm cov kiv cua thiab lub combustion chamber feem.Nyob rau lub sijhawm no, txhawm rau txhim kho thermal efficiency thiab nce qhov kub thiab txias nyob rau hauv pem hauv ntej ntawm lub turbine, cov roj roj ntau dua tuaj yeem hloov mus rau cov kav dej sab nraud los ntawm cov kiv cua uas tsis tshua muaj siab turbine-tsav kiv cua los ntawm cov qauv turbine kom zoo thiab nce kiv cua txoj kab uas hla, yog li no kom tsis txhob muaj qhov nce ntxiv hauv cov pa tawm nrawm.Nyob rau hauv txoj kev no, thermal efficiency thiab propulsion efficiency tau sib npaug, thiab cov efficiency ntawm lub cav tau zoo heev.Kev ua haujlwm siab dua txhais tau hais tias kev siv roj tsawg dua thiab ntev dua ntawm cov dav hlau.Txawm li cas los xij, txoj kab uas hla ntawm lub kiv cua loj tuaj yeem ua rau thaj tsam cua ntawm lub cav, yog li turbofan xyaw nrog qhov sib piv ntau dua 0.3 tsis haum rau lub davhlau supersonic cruise.Txawm hais tias lub cav turbofan txo cov pa tawm ceev, nws tsis txo qhov thrust, vim hais tias txo cov pa ceev ua rau kom lub (sab nraud) tso pa tawm.Los ntawm qhov kev xav ntawm bypass piv, turbofan cav yog kev sib haum xeeb ntawm turbojet cav thiab turboprop cav.
