Aero engines, "lub plawv" ntawm lub dav hlau thiab hailed li "pob zeb diamond ntawm kev lag luam," integrates ntau tej -nt technologies nyob rau hauv niaj hnub kev lag luam, nrog rau cov ntaub ntawv science, machining, thermodynamics, thiab lwm yam kev lag luam. Raws li cov teb chaws xav tau kev ua haujlwm siab dua ntawm lub cav, cov qauv tshiab, thev naus laus zis, thiab cov txheej txheem hauv kev tshawb fawb thiab kev siv txuas ntxiv mus rau qhov kev txwv ntawm kev lag luam niaj hnub no. Ib qho tseem ceeb tshaj plaws rau kev txhim kho qhov thrust - rau - qhov hnyav piv ntawm aero engines yog qhov tseem ceeb ntawm cov hniav disk.
Ua ntej qhov tshwm sim ntawm ib qho kev sib tsoo disks, lub cav rotor hniav tau txuas nrog lub disk siv tenons, grooves, thiab locking devices. Txawm li cas los xij, cov qauv no maj mam dhau los ua tsis txaus rau qhov xav tau ntawm siab -kev ua haujlwm aero cav.
Qhov tseem ceeb bladed disk, integrating lub cav rotor hniav thiab lub disk, yog tom qab tsim thiab tau dhau los ua ib qho tseem ceeb qauv rau siab thrust- rau - luj piv xyaw, dav siv nyob rau hauv ob leeg tub rog thiab pej xeem aero xyaw. Nws cov txiaj ntsig tseem ceeb suav nrog:
1. Txo qhov hnyav
Txij li thaum lub npoo ntawm lub disk tsis xav tau lub machining ntawm grooves rau mounting cov hniav, lub radial dimension ntawm lub npoo tuaj yeem txo qis, yog li txo qhov hnyav ntawm rotor.
2. Txo tus naj npawb ntawm qhov chaw
Dhau li ntawm kev sib xyaw rotor thiab cov hniav, qhov txo qis hauv cov khoom siv xauv kuj yog qhov tseem ceeb. Aero cav muaj cov kev cai nruj heev rau kev ntseeg siab, thiab cov qauv rotor yooj yooj yim ua rau muaj kev ntseeg tau zoo dua.
3. Txo Airflow Poob
Tshem tawm cov cua ntws poob los ntawm qhov tsis sib xws hauv txoj kev sib txuas ib txwm ua kom lub cav ua haujlwm tau zoo thiab ua kom muaj zog.
Thaum txo qhov hnyav thiab nce thrust, qhov tseem ceeb bladed disk, uas muaj txiaj ntsig zoo rau kev txhim kho qhov thrust - rau - qhov hnyav piv, yog ib txwm tsis yooj yim feat. Ntawm ib sab tes, cov khoom siv tsis sib xws feem ntau siv nyuaj - rau- cov khoom siv tshuab xws li titanium alloys thiab siab - kub alloys; Ntawm qhov tod tes, lawv cov hniav yog nyias thiab muaj cov duab nyuaj, ob qho tib si qhov chaw xav tau siab heev ntawm kev tsim tshuab. Tsis tas li ntawd, cov hniav puas rotor tsis tuaj yeem hloov pauv ib tus zuj zus, muaj peev xwm ua rau tag nrho cov hniav disk siv tsis tau, thiab kho thev naus laus zis nthuav tawm lwm qhov kev sib tw.
