Ib tug turbojet: ib daim ntawv thov ntaus ntawv thiab

Ib tug turbojet turbine yog ib tug ntaus ntawv nyob rau hauv uas lub thrust generated los ntawm lub zog hloov dua siab tshiab (kub) nyob rau hauv lub kinetic roj ntsha. Qhov no seb puas tsimnyog tau cov tshuaj tiv thaiv yog siv raws li lub tsav tsheb quab yuam.

Cov feem ntau lug siv thiab cov efficiency ntawm lub turbojet engine tau txais nyob rau hauv aircraft, uas yog tau los tsim ib tug loj sib ntaus ceev (supersonic aircraft).

Muaj ib thiab ob-Circuit Court pab kiag li lawm, uas muaj cov khoom nrog rau cov afterburner yeej tseem zoo siv lug txhim khu cov nqa tawm thiab ya davhlau cravings. Nyob rau tib lub sij hawm rau ib lub high school cov nqi ntawm thrust nce airspeed.

Latitude daim ntawv thov turbojets vim tus kwv tij simplicity ntawm lawv siv thiab tsawg tej ceeb thawj. Lub tsev muaj ib tug combustion chamber, lub turbine, compressor thiab tso nozzle sawv cev rau ib tapering raj, uas yog cov txheej txheem ntawm nyob rau hauv lub tso manifold.

Cua kom tsawg yuav siv sij hawm nyob rau hauv ib tug ua ntej nce nyob rau hauv siab (vim tshaj tawm lub taub hau), uas yog ces nce nyob rau hauv lub compressor. Qhov no ua rau nws tau los mus tsim tej yam kev mob dej siab rau cov combustion txheej txheem thiab siv cov tshav kub nraaj. Permissible kub nyob ntawm nkag ntawm cov roj turbine nyob ntawm seb lub tshav kub tsis kam ntawm cov ntaub ntawv thiab ua hauj lwm zoo ntawm cov turbine cua txias. Ua lub cua siab thiab cov roj kub yog ib tug yam ntxwv feature ntawm feem ntau hom turbine khoom.

Turbojet engine siv nyob rau hauv ib tug unmanned aircraft thiab kev kub ceev, muaj ib tug ntau yam pauv loj nce nyob rau hauv ntsawj afterburning hom, thiab chaw pib lub vim li cas hwj chim thaum xeeb supersonic ceev. Txawm li cas los, cov aggregates siv nyob rau hauv subsonic davhlau, los ntawm tsav tsheb tsis thiab raug nqi tsawg tshaj li lwm yam roj turbine xyaw. Qhov no teeb meem yog vim lub hauv paus ntsiab lus ntawm cov lag luam ntawm tus dais, uas yog txuam nrog kuj kub siab losses thiab tshaj tawm zog mus rau lub tso dej thaum uas tsis muaj davhlau xov tooj (M).

Turbojet nrog lawv ob txhais tes los sau ib qho yooj yim, nws yuav tsum tau ib tug meej kev txawj ntse ntawm nws cov qauv thiab tej ntsiab cai ntawm cov lag luam ntawm tag nrho cov ntsiab.

Tus ntaus ntawv muaj xws li nyob rau hauv nws muaj pes tsawg leeg system ntawm cov roj compressor, uas yog cov txheej txheem ntawm nyob nruab nrab ntawm lub lag thiab cov inlet. Vim generated los ntawm cov combustion ntawm roj zog, lub turbine drives lub compressor thiab muab ntsawj.

Xav paub xov kos duab thiab suav ntawm lub Cheebtsam ntawm lub propulsion system, raws li zoo raws li reciprocating xyaw, yog heev ntau haiv neeg. Qhov chaw sib txawv yuav pom ncauj lus kom ntxaws kwv thiab yooj yim piav rau cov tshuab, uas tso cai rau koj mus ua ib tug qhob dav hlau engine.

Cov units, uas yog ntsia centrifugal twj muaj ib tug afterburner. Lub gases tawm hauv lub turbine nkag mus rau lub dav hlau nozzle, thiab ces tas nyob rau hauv cov cua ntawm ib tug kub ceev. Thrust yog generated los ntawm incrementing tus tshaj tawm roj tawm lub engine.
