Txhawm rau txo qhov hnyav, cov tawv nqaij feem ntau nyias nyias. Thiab qee lub dav hlau, lub fuselage yog ua los ntawm cov khoom siv txhuas, cov cua sov ua haujlwm kuj tsis zoo, thiab cov txheej txheem vuam hauv vuam yuav tsim cov cua sov ntau, uas yog pom tseeb tsis haum rau lub dav hlau aluminium fuselage.
Qhov vuam zoo feem ntau nyob ntawm cov kev txawj ntawm cov neeg ua haujlwm. Lub vuam yog nyias thiab tuab, thiab qhov randomness kuj loj, yog li nws yog ib qho nyuaj rau tsim ib qho kev sib koom ua ke.
Thiab cov txheej txheem riveting siv nyob rau hauv cov rivets, qhov kev ua yuam kev tsis yog me me, yooj yim rau kev tswj kom zoo thiab cov qauv tsim.
Qhov tseeb, cov rivets siv nyob rau hauv kev lag luam aviation yog feem ntau convex taub hau thiab faus lub taub hau rivets. Nyob rau hauv sab hauv ntawm lub dav hlau, vim hais tias tsis muaj aerodynamic zoo li yuav tsum tau, tus nqi tseem ceeb yog tsawg, yooj yim rau txheej txheem lub taub hau convex rivet.
Cov rivets feem ntau yog siv rau qhov du ntawm qhov pom ntawm lub dav hlau, uas tuaj yeem txo qhov tsis kam ntawm lub dav hlau. Hauv kev ua cov txheej txheem, muaj cov kev cai nruj rau kev ua siab ntev ntawm tus ntsia thawv hau thiab cov qauv nyob ze. Thaum koj kov lub dav hlau saum npoo, koj tsis tuaj yeem xav tias muaj cov rivets.
