Surging - yog dab tsi? Ua thiab kho qhov teeb meem

Surging - yog dab tsi? Los ntawm no txhais yog meant cov tsis ua hauj lwm ntawm lub ruaj khov lag luam ntawm aircraft engine, ib tug ua txhaum ntawm nws cov roj-dynamic tsis. Surging yog nrog los ntawm ceev tsis engine thrust, cottons nrog emission ntawm haus luam yeeb thiab nplaim taws los ntawm cov turbine, qhov tshwm sim ntawm teeb meem loj deeg nyob rau hauv lub aircraft. Feem ntau, tag nrho cov no ua rau yus puas tsuaj ntawm lub cav.

Yuav ua li cas tshwm sim thaum ib tug surge ntawm aircraft cav?

Surging - yog dab tsi? Qhov no tshwm sim tshwm sim raws li ib tug tshwm sim ntawm losses pab sib hloov ntawm lub turbine tuaj. Cov txheej txheem muaj ib tug ib txwm rau nws tus kheej-expansion. Cov uas ua cua kiv atherosclerosis engine khob. Ua kev sib hloov ntawm lub tib lub feem ntawm lub rhuab cua nyob rau hauv lub turbine ua rau ib tug tseem ceeb nce nyob rau hauv aircraft engine compressor kub.

Surging - yog dab tsi? Lag luam ntawm lub cav nyob rau hauv lub surge hom, nws thiaj li ua rau rupture nrog rau tom ntej kev puas tsuaj. Nws muaj txhawb rau qhov no tsis muaj zog tuaj thiab feem pa hauv paus explosions vim ntev li kub sawv.

Yuav ua li cas tshem tawm cov surge thaum lub sij hawm lub davhlau?

Hais tias pilots coj mus rau tshem tawm cov surging ntawm lub turbocharger thaum lub sij hawm lub zog ntawm tus aircraft? Nyob rau hauv paub qhov teeb meem yuav pib aircraft engine yog hloov dua siab tshiab rau hauv "me me roj" hom los yog switched zoo rau nws. Nyob rau hauv lub caij nyoog kawg no cov ntaub ntawv, lub surge nyhuv disappears los ntawm nws tus kheej. Nws yuav tsum tau muab sau tseg tias thaum ib qho teeb meem tshwm sim nyob rau hauv lub turbine roj kub nce mus catastrophic ntsuas rau lub thib ob. Yog li ntawd, ib tug raws sij hawm disconnection ntawm lub puas engine yog tsis tshua muaj ib qho tseem ceeb nyob rau hauv kev tiv thaiv kev puas tsuaj.

Nyob rau niaj hnub aircraft xyaw ntsia hluav taws-kev tiv thaiv automatics. Nws lub lag luam yuav pab tau tshem tawm yam tseem ceeb uas ua rau engine surge, tsis muaj qhov yuav tsum tau rau concerted kev txiav txim los cov neeg coob ntawm ib tug aircraft. Tshuav rau lub automation ntawm ib tug thib ob txo siab nyob rau hauv lub turbine, thiab cov roj mov yog tu ncua. Tag nrho cov no ua rau nws tau los mus tiv thaiv ntxiv hluav taws cav nyob rau hauv lub davhlau.

Engineering kev daws teeb meem los mus tshem tawm surging engine

Lub ntsiab txoj kev uas yuav tshwj kom txhob tshwm sim ntawm tus surge nyob rau hauv chaw ua dav hlua yog rau nruab rau tus cua lub cev muaj zog txog ntsha nrog coaxial shafts. Cov yav tas yog tau tig nws tus kheej nrog hwm rau txhua lwm yam nyob rau txawv speeds. Txhua coaxial ncej yog lub luag hauj lwm rau ib feem ntawm lub turbine thiab compressor.

Ntawm lwm yam, lub engineers muab raws li nram no:

1. Tsav yog mounted rau lub adjustable qhia vanes ntawm lub turbine. Qhov no pab cov blasting tuaj uas tau tsim nyob rau surge breakdowns.
2. Cua bypass li qub yog siv los daws tshaj siab nyob rau hauv lub cav compressor. Yog li, cov huab cua ncig yog thawm los ntawm cov compressor.

yog vim li cas

Yog li ntawd peb pom tau hais tias surge nyob rau hauv chaw ua dav hlua. Tam sim no cia saib yog vim li cas hais tias tej zaum yuav ua rau tshwm sim ntawm tej kev huam yuaj. Surge yuav muab tau los ntawm:

• tshem ntawm cov aircraft rau ntawm prohibitive rau nws ces kaum ntawm nres;
• tearing los yog ib nrab kev puas tsuaj ntawm cov turbine hniav, piv txwv li vim hais tias ntawm lawv cov laus, expiry hnub;
• tsoo lub turbine engine txawv teb chaws yam khoom (cov khib nyiab tawg tsam tso mam li pawv txheej noog flying);
• engineering yuam kev thaum lub cav los yog nws cov kev tswj systems tsim;
• muaj zog gusts ntawm crosswind;
• tseem ceeb heev txos atmospheric siab (yuav tshwm sim thaum uas mus txawv tebchaws dav hlau nyob rau hauv huab cua kub tej yam kev mob nyob rau hauv roob chaw).

Nyob rau hauv xaus

Nyob rau hauv lub tam sim no, peb tau to taub cov khoom, surging - dab tsi. Raws li koj tau pom, muaj ib tug tag nrho ntau ntawm kev daws rau nrog xws thaum muaj xwm ceev tsis muaj. Qhov no yog feem ntau ib phau ntawv shutdown ntawm lub turbine puas los ntawm cov neeg coob ntawm tus aircraft, aircraft engine automatic restart nrog tshwj xeeb systems, advanced triggering tag nrho cov xaiv ntawm sensors uas qhia pilots txog cov kev txaus ntshai ntawm ib tug tua hluav taws engine. Cov uas hais tias, tsis txhob ntshai ya saum huab cua thauj, vim hais tias xws xwm txheej tam sim no tsis tshua muaj heev.
