Iyo bumblebee inobhururuka sei: masimba ezvisikwa uye mitemo yeaerodynamics
Imwe yemhando dzenyuchi dzinowanzozivikanwa ndeye bumblebee. Furry uye ruzha, chipembenene chine mapapiro maduku kana zvichienzaniswa nekukura kwemuviri. Zvinoenderana nemirairo yeaerodynamics, kubhururuka kwechipembenene chine ma parameter akadaro hazvigoneke. Kwenguva yakareba, masayendisiti ave achiita tsvakurudzo kuti anzwisise kuti izvi zvinogoneka sei.
Zviri mukati
Chimiro chemapapiro ebumblebee mukuenzanisa nendege
Kune sainzi yese - bionics, sainzi inosanganisa tekinoroji uye biology. Anodzidza zvipenyu zvakasiyana-siyana uye izvo vanhu vanogona kuzvitora kubva kwavari ivo pachavo.
Vanhu vanowanzotora chimwe chinhu kubva kune zvakasikwa uye kunyatsochidzidza. Asi bumblebee yakatambudza masayendisiti kwenguva yakareba, kana kuti kukwanisa kwayo kubhururuka.
Nyanzvi dzefizikiki dzakaona kuti ndege inobhururuka nekuda kwekugadzirwa kwakaoma kwebapiro uye nzvimbo yeaerodynamic. Kusimudzwa kunobudirira kunopihwa neyakatenderedzwa inotungamira kumucheto kwebapiro uye nemateru ekutevera edge. Engine thrust simba i63300 lbs.
Iyo aerodynamics yekubhururuka kwendege uye bumblebee inofanira kufanana. Masayendisiti akaratidza kuti maererano nemitemo yefizikiki, bumblebees haifaniri kubhururuka. Zvisinei, hazvisi.
Bumblebee hombe nemapapiro ayo.
Mapapiro eBumblebee anokwanisa kugadzira kusimudza kupfuura zvinotarisirwa nesainzi. Kana ndege yacho iine zviyero zvebumblebee, saka yaisazosimuka kubva pasi. Chipembenene chinogona kufananidzwa neherikoputa ine mapanga anochinjika.
Mushure mekuedza dzidziso inoshanda kuBoeing 747 maererano nebumblebees, nyanzvi dzefizikisi dzakaona kuti mapapiro akareba kubva pa300 kusvika ku400 kubhururuka musekondi imwe. Izvi zvinogoneka nekuda kwekukwenya uye kuzorora kwemasumbu emudumbu.
Iyo yakapendwa mapatani emapapiro panguva yekubhururuka ndiyo inokonzera akasiyana aerodynamic masimba. Dzinopesana nedzidziso ipi neipi yemasvomhu. Mapapiro haakwanisi kusvetuka segonhi riri pahinji yakajairika. Chikamu chepamusoro chinogadzira ovha yakatetepa. Mapapiro anogona kubhururuka nesitiroko imwe neimwe, achinongedza kumusoro kumusoro pane inodzika pasi.
Kuwanda kwekurova kwebhubhu mahombe kanokwana ka200 pasekondi. Iyo yakanyanya kumhanya yekubhururuka inosvika 5 metres pasekondi, iyo yakaenzana ne18 km paawa.
Kuburitsa chakavanzika chekubhururuka kwebumblebee
Kuti vaburitse chakavanzika ichi, nyanzvi dzefizikisi dzaifanira kugadzira mhando dzemapapiro ebumblebee mune imwe shanduro yakakura. Somugumisiro weizvi, musayendisiti Dickinson akatanga nzira dzinokosha dzekubhururuka kwezvipembenene. Iwo anosanganisira inononoka stall yekuyerera kwemhepo, kutorwa kwewake jet, inotenderera inotenderera inofamba.
Bapiro rinocheka nemhepo, izvo zvinotungamirira kukupatsanurwa kunononoka kwekuyerera kwemhepo. Kuti irambe ichibhururuka, nyuchi inoda chamupupuri. Vortices hova dzinotenderera dzezvinhu, zvakafanana nemvura inoyerera mudhishi.
Kana bapiro richifamba nekona duku, mhepo inochekwa pamberi pebapiro. Zvadaro pane shanduko yakatsetseka mu 2 inoyerera pamwe nechepasi uye kumusoro kwepamusoro pebapiro. Kumhanya kwepamusoro pemvura kwakakwira. Izvi zvinogadzira lift.
Pamusana pechikamu chekutanga chekudzikisa, kusimudza kunowedzera. Izvi zvinofambiswa nekuyerera kwenguva pfupi - iyo vortex yemucheto wepamberi webapiro. Somugumisiro, kudzvinyirira kwakaderera kunoumbwa, izvo zvinotungamirira pakuwedzera kwekusimudza.
Nokudaro, zvakave zvakasimbiswa kuti bumblebee inobhururuka muhuwandu hwakawanda hwemhepo. Mumwe nomumwe wavo akakomberedzwa nemhepo yemhepo uye madutu maduku akagadzirwa nekuputika kwemapapiro. Mukuwedzera, mapapiro anoumba simba renguva pfupi rine simba rinoonekwa pamagumo uye pakutanga kwegaro rimwe nerimwe.
mhedziso
Pane zvakavanzika zvakawanda muzvisikwa. Kukwanisa kubhururuka mu bumblebees chinhu chakaongororwa nemasayendisiti akawanda. Inogona kunzi chishamiso chechisikigo. Mapapiro madiki anogadzira chamupupuri chine simba uye zvinofema zvekuti zvipembenene zvinobhururuka nekumhanya kukuru.
