Indiza i-bumblebee: amandla emvelo kanye nemithetho ye-aerodynamics
Enye yezinhlobo ezivame kakhulu zezinyosi i-bumblebee. Sinoboya futhi sinomsindo, isinambuzane sinamaphiko amancane uma siqhathaniswa nobukhulu bomzimba waso. Ngokwemithetho ye-aerodynamics, ukundiza kwenambuzane ngemingcele enjalo akunakwenzeka. Sekuyisikhathi eside ososayensi benza ucwaningo ukuze baqonde ukuthi lokhu kungenzeka kanjani.
Okuqukethwe
Ukwakheka kwamaphiko e-bumblebee uma kuqhathaniswa nendiza
Kukhona isayensi yonke - bionics, isayensi ehlanganisa ubuchwepheshe kanye biology. Ufunda ngezinto eziphilayo ezahlukahlukene nokuthi abantu bangazitholela ini kuzo.
Abantu bavame ukuthatha okuthile emvelweni futhi bakufunde ngokucophelela. Kodwa i-bumblebee yahlupha ososayensi isikhathi eside, noma kunalokho ikhono layo lokundiza.
Izazi zefiziksi ziye zathola ukuthi indiza indiza ngenxa yomklamo oyinkimbinkimbi wephiko kanye nendawo ezungezayo. Ukuphakamisa okusebenzayo kunikezwa unqenqema oluyindilinga oluholayo lwephiko kanye nomphetho owumqansa olandelanayo. Amandla enjini angama-63300 lbs.
I-aerodynamics yokundiza kwendiza kanye ne-bumblebee kufanele kufane. Ososayensi baye bafakazela ukuthi ngokwemithetho ye-physics, izinyosi akufanele zindize. Nokho, akunjalo.
I-bumblebee enkulu namaphiko ayo.
Amaphiko e-Bumblebee ayakwazi ukudala ukuphakama okuningi kunalokho okulindeleke ososayensi. Uma indiza yayinezilinganiso ze-bumblebee, yayingeke isuke phansi. Isinambuzane singafaniswa nendiza enophephela emhlane enama-blade aguquguqukayo.
Ngemva kokuhlola ithiyori esebenza ku-Boeing 747 maqondana nama-bumblebees, izazi zefiziksi zathola ukuthi i-wingspan isuka ku-300 kuya ku-400 flaps ngomzuzwana ongu-1. Lokhu kungenzeka ngenxa yokufinyela nokuphumula kwemisipha yesisu.
Amaphethini apendiwe amaphiko ngesikhathi sokushaywa yimbangela yamandla ahlukahlukene we-aerodynamic. Ziphikisana nanoma iyiphi inkolelo-mbono yezibalo. Amaphiko awakwazi ukushwiba njengomnyango obekwe phezu kwehinji evamile. Ingxenye engenhla yenza i-oval encane. Amaphiko angaphenduka ngokushaya ngakunye, akhombe phezulu phezulu ngokushaya phansi.
Imvamisa yokushaywa kwezinyosi ezinkulu okungenani izikhathi ezingama-200 ngomzuzwana. Isivinini esikhulu sokundiza sifinyelela ku-5 metres ngomzuzwana, okulingana no-18 km ngehora.
Ukudalula imfihlakalo yendiza ye-bumblebee
Ukuze zixazulule le mpicabadala, izazi zefiziksi kwadingeka zakhe amamodeli amaphiko ezinyosi ngenguqulo ekhulisiwe. Ngenxa yalokhu, usosayensi uDickinson wasungula izinqubo eziyisisekelo zokundiza kwezinambuzane. Ahlanganisa itafula elincane lokugeleza komoya, ukuthwebula i-wake jet, ukunyakaza okuyindilinga okujikelezayo.
Iphiko linqamula emoyeni, okuholela ekuhlukaneni kancane kokugeleza komoya. Ukuze ihlale indize, inyosi idinga isivunguvungu. Ama-vortice ayimifudlana yento ezungezayo, efana namanzi ageleza kusinki.
Lapho iphiko lihamba nge-engeli encane, umoya usikwa phambi kwephiko. Bese kuba khona ukuguquguquka okushelelayo kokugeleza okungu-2 eduze nendawo ephansi nengaphezulu yephiko. Isivinini esikhuphuka nomfula siphezulu. Lokhu kukhiqiza i-lift.
Ngenxa yesigaba sokuqala sokunciphisa, ukuphakama kuyanda. Lokhu kwenziwa lula ukugeleza okufushane - i-vortex yonqenqema oluhamba phambili lwephiko. Ngenxa yalokho, ukucindezela okuphansi kwakhiwa, okuholela ekwandeni kokuphakanyiswa.
Ngakho-ke, kuye kwatholakala ukuthi i-bumblebee indiza ngenani elikhulu lama-vortices. Ngayinye yazo izungezwe imisinga yomoya kanye nezivunguvungu ezincane ezidalwe ukubhakuzisa kwamaphiko. Ngaphezu kwalokho, amaphiko akha amandla esikhashana anamandla avela ekugcineni nasekuqaleni kwe-stroke ngayinye.
isiphetho
Ziningi izimfihlakalo emvelweni. Ikhono lokundiza kuma-bumblebees yinto eye yacwaningwa ososayensi abaningi. Kungabizwa ngokuthi isimangaliso semvelo. Amaphiko amancane adala izivunguvungu namandla kangangokuthi izinambuzane zindiza ngesivinini esikhulu.
