iavyog ib hom khoom seem uas tau siv dav hauv lub neej, txawm tias nws yog aviation, freighter, tsheb thiab lwm yam. Txawm li cas los xij, thaum lub iav tsim thiab ua tiav, nws yuav tsum muaj pes tsawg lub iav. Yog tias nws tsawg dua kaum xya, nws tsis tuaj yeem tig. Koj puas paub vim li cas?
Ua ntej tshaj plaws, yog vim li cas vim li cas cov iav tuaj yeem tig yog vim tias ib khub ntawm kev sib raug zoo sib kis yuav tsum tau tsim los ntawm cov iav sab sauv thiab cov iav qis. Tsuas yog thaum qhov kev sib txuas ntawm ob qho tib si nyob rau hauv qhov chaw, nws txoj kev ua haujlwm tuaj yeem yog kev sib raug zoo. Ua ib qho piv txwv, ob lub zog tsuas tuaj yeem ua lawv lub luag haujlwm yog tias lawv mesh zoo. Tshwj xeeb, lawv tau muab faib ua ob hom:spur zogthiabhelical iav.
Lub coefficient ntawm qhov siab ntawm qhov addendum ntawm tus qauv spur iav yog 1, lub coefficient ntawm qhov siab ntawm lub denendum yog 1.25, thiab cov degree ntawm nws lub kaum sab xis siab yuav tsum ncav cuag 20 degrees. Nws yog tib ob lub zog.
Yog hais tias tus naj npawb ntawm cov hniav ntawm lub embryo tsawg dua ib qho nqi, ib feem ntawm cov hauv paus hniav ntawm cov hauv paus hniav yuav raug khawb tawm, uas yog hu ua undercutting. Yog hais tias lub undercut me me, nws yuav cuam tshuam lub zog thiab stability ntawm lub iav. Kaum xya hais no yog rauiav.
Tsis tas li ntawd, kaum xya yog tus lej tseem ceeb, uas yog hais tias, tus naj npawb ntawm kev sib tshooj ntawm qee tus hniav ntawm cov iav thiab lwm yam iav yog qhov tsawg tshaj plaws nyob rau hauv ib qho ntawm cov lem, thiab nws yuav tsis nyob ntawm qhov no mus ntev. thaum siv zog. Gears yog cov cuab yeej precision. Txawm hais tias yuav muaj qhov yuam kev ntawm txhua lub iav, qhov tshwm sim ntawm lub log ncej hnav ntawm Seventeen yog siab dhau, yog li yog tias nws yog Kaum Ib Hlis, nws yuav zoo rau lub sijhawm luv luv, tab sis nws yuav tsis ua haujlwm ntev.
