Aircraft engine surge - yog dab tsi? Lub ntsiab lus yuav tsum tau nkag siab tias yog kev cuam tshuam ntawm kev ua haujlwm ntawm turbojet chav tsev ntawm lub dav hlau, kev ua txhaum ntawm kev ruaj ntseg ntawm nws txoj haujlwm. Cov cim qhia ntawm qhov teeb meem no yog tshwm sim ntawm pops, pa luam yeeb, txo traction, muaj zog vibrations.

Aircraft engine surge - yog dab tsi? Nyob rau hauv qhov tseeb, nyob rau hauv lub hauv paus ntawm qhov teeb meem lies qhov poob ntawm ib tug tsis tu ncua ntawm cov huab cua ntws los ntawm lub turbine. Yog tias tsis kho, nws tuaj yeem ua rau hluav taws thiab ua kom lub cav puas.

Aircraft engine surge: ua rau

Ntawm cov laj thawj uas tuaj yeem ua rau muaj teeb meem, nws tsim nyog qhia:

• muab lub dav hlau tso rau ntawm qhov kev npau taws heev, uas qhov siab tshaj plaws tau muab tso rau ntawm lub cav;
• impeller vane puas vim qhov kawg ntawm lub neej lossis tsis ua haujlwm;
• tau txais khoom txawv teb chaws rau hauv lub cav;
• muaj zog hla cua daj cua dub;
• critically low ambient air pressure.

rau dab tsiCov kev daws teeb meem siv rau hauv aviation los tiv thaiv kev nce siab?

Kev siv ob peb lub shafts sib cais hauv kev tsim qauv yog qhov kev daws teeb meem tseem ceeb los tiv thaiv lub cav surge. Qhov no yog dab tsi? Cov shafts nyob rau hauv lub cav txav ntawm qhov sib txawv speeds, ntawm nws tus kheej ntawm ib leeg. Txhua ntawm lawv nqa ib feem ntawm lub turbine thiab compressor ntawm lub cav. Nyob rau niaj hnub aircraft, units feem ntau yog ntsia uas muaj 2-3 shafts ywj siab. Yog tias ib qho ntawm lawv ua tsis tiav, tus so muaj peev xwm tswj tau lub zog uas yuav tsum tau txav lub nkoj hauv airspace.

Yuav ua li cas tshem tawm qhov nce siab thaum lub davhlau?

Aircraft engine surge - yog dab tsi? Qhov no tshwm sim sai sai ua rau kev puas tsuaj ntawm lub cav thaum lub davhlau. Thaum muaj xwm txheej ceev, cov kws tsav dav hlau hloov lub cav mus rau qhov txo qis lossis ua kom tiav tag rau ib ntus. Yog tias qhov teeb meem raug kuaj pom thaum ntxov thiab txoj hauv kev no tau siv, qhov kev nce siab feem ntau ploj ntawm nws tus kheej.

Qhov kub ntawm lub cav thaum lub sijhawm nce siab tuaj yeem ua rau ntau pua degrees ib ob. Yog li ntawd, kev tua hluav taws tsis siv neeg raug ntsia rau ntawm cov dav hlau niaj hnub. Nws tso cai rau koj tshem tawm qhov hluav taws kub, uas muab sijhawm rau cov neeg coob los txiav txim siab. Thaum lub automation tshwm sim, ib qho kev cuam tshuam lossis txo cov khoom siv roj tshwm sim ib txhij.

Ib lub dav hlau tuaj yeem xa mus rau hauv kev dhia dej dawb rau ib ntus yog tias muaj lub cav nce siab tshwm sim. Qhov no yog dab tsi? Txhua lub cav raug muab tua rau ntawm lub nkoj. Lub dav hlau pib maj mam poob qhov siab kom txog thaum hluav taws tshem tawm. Tsis tas li ntawd, cov khoom siv roj tau rov qab los rau hauv lub cav thiab rov qab mus rau hom kev ya davhlau zoo li tshwm sim.

In xaus

Engine surge yuav muaj teeb meem heev thaum lub davhlau. Txawm li cas los xij, niaj hnub kev nce qib hauv kev tshawb fawb thiab thev naus laus zis ua rau nws muaj peev xwm daws tau qhov tshwm sim no. Niaj hnub no, lub dav hlau tau nruab nrog txhua yam kev taw qhia cov khoom siv rau cov neeg coob, kev tua hluav taws automation, cov tshuab ua kom lub sijhawm tua lub tsev thiab rov pib dua.
