Aerospace Aircraft Daim tawv nqaij Laser ntxuav thiab tshem tawm

 

1. Qhov zoo ntawm Laser ntxuav tshuab kom tshem tawm cov tawv nqaij
Kev nyab xeeb ntawm lub dav hlau yog qhov tseem ceeb heev. Yog li ntawd, kev nyab xeeb yog suav tias yog lub hauv paus tseem ceeb hauv txhua txoj haujlwm ntawm kev tsim dav hlau, suav nrog kev tsim khoom thiab kev saib xyuas.

 

Txhawm rau kom muaj kev nyab xeeb ntawm lub dav hlau, lub dav hlau yuav tsum tau muab tshem tawm thiab rov kho dua txhua tsib xyoos lossis ntau dua. Thaum lub sij hawm tu lub dav hlau, cov xim ntawm lub dav hlau yuav tsum tau muab tshem tawm thiab lub dav hlau daim tawv nqaij saum npoo yuav tsum tau kuaj xyuas qhov tsis zoo corrosion thiab qaug zog tawg kom tsis txhob muaj kev sib tsoo. Rau kev ceev faj tshem tawm cov xim ntawm lub dav hlau ntawm daim tawv nqaij, kev saib xyuas zoo yuav tsum tau them rau kev tiv thaiv cov khoom siv hauv paus, piv txwv li tsis ua rau nws puas tsuaj.

 

Cov xim stripping txoj kev siv yav dhau los tsis tsuas yog ua phem rau ib puag ncig thiab ua phem rau kev noj qab haus huv ntawm cov neeg ua haujlwm, tab sis kuj raug nqi nyiaj. Piv nrog rau cov kev cai no, lub tshuab ntxuav laser muaj ntau yam zoo xws li tsis muaj kuab paug, tsis muaj kev puas tsuaj, thiab tsis muaj kev ntxhov siab. Tsis tas li ntawd, nws tseem tuaj yeem siv tau yooj yim rau cov kab ntau lawm. Qhov tseem ceeb tshaj, lub tshuab ntxuav laser tuaj yeem ntxuav cov khoom ua haujlwm zoo thiab ntau yam khoom hauv qhov chaw me me nrog kev ua haujlwm siab thiab ua haujlwm zoo. Nws yog qhov tsim nyog rau kev saib xyuas ntawm cov tawv nqaij dav hlau thiab tshem tawm cov xim ntawm lawv.

 

 

2. Txoj Cai Ua Haujlwm ntawm Laser Ntxuav Tshuab kom tshem tawm cov tawv nqaij tawv nqaij
Laser beams muaj cov yam ntxwv ntawm lub zog siab ceev, tswj tau kev taw qhia, thiab convergence. Lub tshuab ntxhua khaub ncaws laser siv nws los rhuav tshem kev sib txuas ntawm cov xim thiab cov tawv nqaij ntawm lub dav hlau, vaporize cov xim, thiab tshem tawm ntawm daim tawv nqaij ntawm lub dav hlau. Thaum cov xim ntawm daim tawv nqaij ntawm lub dav hlau absorbs lub zog ntawm lub laser beam, nws sai sai expands thiab vaporizes kom txo tau nws lub zog ntawm lub aircraft ntawm daim tawv nqaij nto. Raws li lub zog hluav taws xob nce, cov xim pleev xim rau ntawm daim tawv nqaij ntawm lub dav hlau vibrate thiab poob tawm.

 

Tag nrho cov txheej txheem laser ntxuav ntawm lub dav hlau ntawm daim tawv nqaij yog kwv yees faib ua plaub theem, xws li laser vaporization thiab decomposition, laser tev, thermal expansion ntawm cov xim hais, aircraft ntawm daim tawv nqaij nto vibration thiab xim sib cais.

 

Lub schematic daim duab ntawm laser ntxuav yog raws li nram no:

 

 

3. Kev ceev faj rau daim ntawv thov ntawm Laser ntxuav tshuab
Nyob rau hauv daim ntawv thov ntxuav laser, nws yog ib qho tsim nyog yuav tsum xav txog qhov chaw tu lub laser rau kev tu lub dav hlau ntawm daim tawv nqaij thiab xaiv cov laser wavelength uas tsim nyog kom ua tiav cov txiaj ntsig zoo tshaj plaws. Lub tshuab ntxuav laser tuaj yeem hloov cov qauv thiab kev taw qhia ntawm lub dav hlau daim tawv nqaij xim, tswj qhov roughness ntawm daim tawv nqaij ntawm lub dav hlau, thiab txhim kho nws cov kev ua tau zoo tag nrho yam tsis muaj kev puas tsuaj rau daim tawv nqaij. Kev tshem tawm cov nyhuv ntawm lub dav hlau daim tawv nqaij yog feem ntau cuam tshuam los ntawm cov yam ntxwv ntawm lub nqaj, lub cev tsis zoo ntawm lub dav hlau daim tawv nqaij thiab cov xim, thiab cov xim nqus lub peev xwm ntawm lub laser beam.
