Kev cuam tshuam los nag ib puag ncig rau cov khoom siv
(1) Atmospheric ib puag ncig
- Txwv qhov ua tau zoo ntawm radar.
- Kev txwv dav hlau ua haujlwm vim txo qis kev pom thiab txo qis nqa nqa (tsuas yog thaum nag hnyav).
- Ua puas lub aircraft nyob rau hauv lub davhlau.
- Muaj feem cuam tshuam rau kev tua hluav taws thiab foob pob hluav taws.
- Txo qhov kev saib xyuas qhov muag pom, txawm tias tsis tuaj yeem nqa tawm kev saib xyuas qhov muag.
- Txo kev ua haujlwm sab nraum zoov.
- Ua rau misoperation ntawm fuze.
- Txo qhov pom ntawm cov khoom siv kho qhov muag.
(2) Los nag ntaus
Los nag cuam tshuam erodes cov cuab yeej nto.
(3) Ncua nag / infiltration
- Ua rau muaj zog txo / o ntawm qee cov ntaub ntawv.
- Muaj peev xwm ntawm xeb, corrosion, thiab txawm pwm loj hlob.
- Ua kom qhov hnyav ntawm cov khoom siv.
- Ua kom cov khoom siv hluav taws xob thiab hluav taws xob siv tsis tau lossis tsis muaj kev nyab xeeb.
- Cov khoom siv hluav taws xob ua tsis tiav.
- Cov dej khov hauv cov khoom siv tuaj yeem ua rau qeeb qeeb thiab ua haujlwm tsis ua haujlwm vim kev nthuav dav lossis tawg ntawm cov khoom.
- Hloov pauv cov cua sov.
- Propellant combustion yog qeeb.
Common rain test standard
Ib qho ntawm cov qauv siv los nag ntau tshaj plaws yog IP (Ingress Protection) ntsuas qhov system. Lub kaw lus no muab ob tus lej code uas qhia txog qib kev tiv thaiv los ntawm cov khoom tiv thaiv plua plav thiab dej. Thawj tus lej sawv cev rau qib ntawm kev tiv thaiv cov khoom siv, thaum tus lej thib ob sawv cev rau qib kev tiv thaiv cov kua.
Lwm qhov tseem ceeb ntawm kev ntsuas dej nag yog ASTM (American Society for Testing and Materials) D4585 test method. Txoj kev no suav nrog kev nthuav tawm cov khoom lag luam kom tswj tau cov dej los ntawm cov dej nag simulator, thaum ntsuas cov dej uas nkag mus los ntawm cov khoom.
ISO (International Organization for Standardization) 20653 tus qauv kuj tseem siv los ntsuas qhov tsis kam ntawm cov khoom rau dej nkag. Cov qauv no suav nrog kev xa cov khoom mus rau qhov dej nag uas tau teev tseg, thaum ntsuas cov dej uas nkag mus rau hauv cov khoom.
