Toroidal propellers anovimbisa kunyaradza drones uye mota dzemugungwa 2g5cr

Parizvino, mota zhinji - ingave mhepo kana gungwa - dzinoshandisa mapropeller dzine akawanda-rotor propellers sekubvumirana. Izvi zvinogona kuchinja munguva pfupi iri kutevera nekuvandudzwa uku MIT Lincoln Laboratory uye kambani yeNorth America Sharrow Marine iyo inovimbisa kushandura mapropeller kuita michina yakanyarara uye inotowedzera simba. 5y141p

Iko kugona kwe toroidal propellers mune drones 4r2t4v

Iwe zvechokwadi wanga uri munzvimbo yakavhurika yakavhurika uchinakidzwa iwe wega kana neshamwari, uye kamwe kamwe isinganzwisisike uye inogumbura yakakwira-inonzwika ruzha rwakatora runyararo rwako rwepfungwa uye nekunetsekana iwe pamusoro pezvaiswedera, handiti?! 

Pawakatarisa kumusoro, wakaona kuti yakanga isiri ndege kana UFO, asi ingori diki asi ine ruzha.

Ruzha urwu rusinganzwisisike rwunokonzerwa nemadrones rwave kuwanda munzvimbo dzese, kubva kumahombekombe kusvika kumapaki, uye sezvo mukurumbira wezvinhu izvi uri kukura uye mashandisiro azvo ari kuwedzera, zvichawedzera kuwanda kuti mheremhere iyi iitike. maguta, zvichiunza kusagadzikana uye kusagadzikana. Tichifunga izvi, vashandi pa Massachusetts Institute of Technology (MIT) uye kambani Sharrow Marine Vachagadzira mhinduro ine hungwaru kune izvi nemamwe matambudziko, akadai seruzha rwakakura rwunoitwa nemainjini ezvikepe.

As toroidal propellers, sekutumidzwa kwavakaitwa neInstitute, vane chimiro chakasiyana kwazvo apo mashizha maviri akabatana, achigadzira mhepo yakazaruka pakati pawo, iyo inoshanda nenzira yehungwaru, inodzima ruzha runokonzerwa nekushanda kwemidziyo. Haangoshandi chete mune zvinonzwisisika zvema drones, uko mapropeller ari madiki, asi aratidzawo kuti anoshanda pazvikepe, kwete chete kuderedza ruzha uye kudedera, asi kuti abudise kubudirira kukuru mukushanda kweinjini pachayo.

Toroidal propellers pazvikepe 4k344x

Panyaya yekushanda pamabhoti, mapropeller aya anotangazve kufambira mberi kwakakosha munzvimbo iyo yakaguma yamira muna 1890 uye inotonyanya kushanda uye ine simba kupfuura drones. 

"Paive nemamwe madhizaini aive mapapiro emhete aya. Saka ndakafunga kuti zvaizoita sei kana ukatora bapiro redenderedzwa woshandura chinhu chakadaro kuita propeller."

Dr. Thomas Sebastian, nhengo yepamusoro murabhoritari yeThermal and Structural Fluids Engineering Group.

Kana zvasvika kune hydrodynamics, ivo havangodzikisi ruzha, asi zvakare vane akati wandei mamwe mabhenefiti anoita iyo toroidal propellers imwe yehukuru hutsva hwemazuva ano hwenzvimbo iyi - tichifunga kuti mumakore zana apfuura kwave kushoma kana kushaikwa kufambira mberi - sekuwedzera reverse thrust ne100%, 50% yakawanda siyana, kushomeka kwekudedera uye kaviri kumhanya panguva yepakati RPMs. 

Izvi zvinogoneka chete nekuti mapropeller aya anobvisa makomba ari kumagumo ari maratidziro eakajairwa propeller, uye mhedzisiro yacho yakatoratidzwa nekambani muvhidhiyo.

Imwe yekunetsekana kukuru kwemasangano anodzora ane basa rekugadzirisa drones Ndizvo chaizvo ruzha uye kunetsa kwakawanda izvo michina iyi inogona kukonzera mumaguta makuru kana yakanyatso shandiswa kune yavo yakazara kugona - izvo, sezvatinoziva, hazvisi zvishoma.

Drones vagara vachivimbisa kushandura mabatiro atinoita kuendesa mhepo, kutariswa kwemaindasitiri nekuongorora uye kunyangwe kuchengetedzwa kweveruzhinji.

Tarisiro ndeyekuti kunyangwe vachiri muchikamu chekuyedza, vaine mabhenefiti akajeka uye akajeka akaratidzwa nemapropeller aya, inyaya yenguva vasati vatumirwa kugadzirwa kwakawanda uye vanogona kubatsira kuhupenyu hwevagariwo zvavo seni. uye iwe.

Iyo toroidal propeller, imwe yeLab's @RD100Awards vanokunda, ine yakasarudzika, yakavharika-fomu propeller dhizaini inoita kuti ive yakanyarara imwe nzira kune yakajairwa multirotor propeller pamotokari dzemuchadenga dzisina kugadzirwa. https://t.co/hgda3NgYIz pic.twitter.com/5XkIxNVPHd

"Chinhu chikuru chataifunga nezvacho mukuita kuti mapropeller anyarare inyaya yekuti zvino wave kugovera mavhoti ari kugadzirwa nepropeller pachimiro chese chepropeller pachinzvimbo chemuromo chete. Izvo zvinoita kuti ibudirire kuparara nekukurumidza mumhepo. Iyi vortex haifambe kusvika kure, saka haugone kuzvinzwa "-

Thomas Sebastian.

Haisi kurota kana remangwana zano rekuti drones ishandiswe pakuunza. To amazon, semuenzaniso, anga achironga zano iri kubva 2013, uye muna 2022 the Ifood yakagamuchira mvumo kubva kuNational Civil Aviation Agency (Anac) yekuendesa kuburikidza nedrone.

Nekugoverwa kweramangwana uye kufarirwa kweava mapropeller matsva, rimwe rematambudziko makuru akatariswa nemasangano richagadziriswa, uye drones ichakwanisa kuti mashandisiro adzo awedzere kuongororwa, uye isu tichakwanisa kuita kuti zvigadzirwa zvedu zviitwe mubhizinesi risingasviki rimwechete. zuva.
