Txhais. Cav Siab ratio ( EPR ), nyob rau hauv lub dav hlau cav, yog qhov piv ntawm lub turbine tawm siab muab faib los ntawm compressor inlet siab.

Ib yam li ntawd, koj tuaj yeem nug, EPR txhais li cas hauv kev dav hlau?

cav siab piv

Qhov twg yog qhov siab tshaj plaws nyob rau hauv lub cav turbine? Siab tshaj plaws yog ua tiav ntawm qhov tawm ntawm lub diffuser vanes / nkag mus rau qhov chaw combustion Siab tshaj Kev tshaj tawm yog ua tiav nyob rau hauv ob qho tib si NGV qhov tawm los yog ntawm qhov tso pa tawm. Siab yuav tsum yog siab tshaj Nyob rau hauv lub combustion chamber inlet (tsuas yog tom qab lub kawg compressor theem) los tiv thaiv compressor stalls.

Tom qab ntawd, dab tsi yog n1 thiab n2 hauv lub tshuab dav hlau?

N1 thiab N2 yog cov rotational speeds cav seem qhia raws li feem pua ntawm tus nqi nominal. Thawj spool yog lub siab tsis tshua muaj compressor (LP), uas yog N1 thiab qhov thib ob spool yog lub siab compressor (HP), uas yog N2 . Cov shafts ntawm cav tsis txuas thiab lawv ua haujlwm sib cais.

Ram drag yog dab tsi?

ram zog . Qhov poob ntawm thrust nyob rau hauv lub turbofan los yog turbojet lub cav uas yog tshwm sim los ntawm kev nce qhov ceev ntawm huab cua nkag mus rau hauv lub cav. Ram luag yog qhov sib txawv ntawm tag nrho thrust thiab net thrust.

Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?

Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam

Cov kauj ruam ntawm mitosis yog dab tsi thiab dab tsi tshwm sim hauv txhua qhov?

Mitosis muaj tsib theem sib txawv: interphase, prophase, metaphase, anaphase thiab telophase. Cov txheej txheem ntawm cell faib tsuas yog ua tiav tom qab cytokinesis, uas tshwm sim thaum lub sij hawm anaphase thiab telophase. Txhua theem ntawm mitosis yog tsim nyog rau cell replication thiab faib

Lub zog hauv aviation yog dab tsi?

Lub dav hlau nyob rau hauv ncaj-thiab-theem ya tsis nrawm yog ua los ntawm plaub lub zog - nqa, lub zog ua haujlwm siab; hnyav, los yog lub ntiajteb txawj nqus, lub zog downward acting; thrust, lub zog ua haujlwm pem hauv ntej; thiab luag, rov qab ua yeeb yam, los yog retarding quab yuam ntawm cua tsis kam. Lift opposes lub ntiajteb txawj nqus
