Muhimmancin fasaha na injin eVTOL

1. Halayen fasaha namotar eVTOL

In rarraba wutar lantarkiMotoci suna tuƙa propellers da yawa ko fanka a kan fikafikai ko fuselage don samar da tsarin turawa wanda ke ba da ƙarfin turawa ga jirgin. Yawan ƙarfin motar kai tsaye yana shafar ƙarfin ɗaukar nauyin jirgin. Ƙarfin fitarwar wutar lantarki, aminci da daidaitawar muhalli na motar muhimman abubuwa ne don tantance halayen motsi da amincin jiragen da ake tura wutar lantarki. Zaɓin motocin lantarki, jiragen sama marasa matuƙa da injinan eVTOL ya bambanta saboda farashi daban-daban, yanayin aikace-aikace da sauran dalilai [1].

1) Motocin lantarki: ƙarin maganadisu na dindindininjinan synchronous,Injinan maganadisu na dindindin waɗanda ke da inganci mafi girma da ƙarfin juyi mai girma na iya samar da ingantacciyar ƙwarewar tuƙi. A lokaci guda, yawan ƙarfin injinan maganadisu na dindindin na iya taimakawa motocin lantarki su sami ƙarfi mafi girma a ƙarƙashin girma ɗaya.

(2) UAV: ​​wanda aka saba amfani da shi ba tare da goga baMotar DC.Motar DC mara gogewa tana da ƙarancin nauyi da hayaniya, kuma farashin kulawa yana da ƙasa, wanda ya dace da buƙatun tashi na UAVs; Na biyu, saurin motar DC mara gogewa ya fi girma, wanda ya dace da buƙatun tashi mai sauri na jiragen sama marasa matuƙa. Misali, DJI yana amfani da injinan gogewa.

(3) eVTOL: Babban buƙatu don ingancin mota da yawan ƙarfin juyi, injin synchronous na magnet na dindindin mafita ce mai matuƙar kyau ga tsarin wutar lantarki, saboda injin magnet na dindindin na axial flux yana da babban adadin amfani da sararin radial, kuma yawan ƙarfin lantarki da yawan juyi suna da fa'idodi idan aka kwatanta da ƙaramin diamita na diamita. Jiragen VTOL na lantarki na yanzu, kamar Joby S4 da Archer Midnight, duk suna amfani da injinan synchronous na magnet na dindindin [1].

2. Tsarin haɓaka motoci na eVTOL
A halin yanzu, babban ci gaban tsarin wutar lantarki na eVTOL shine rage nauyin tsarin motar da kuma nauyin taimako na tsarin sanyaya ta hanyar inganta fasahar ƙirar lantarki, fasahar sarrafa zafi da fasahar sauƙi, da kuma ci gaba da inganta yawan ƙarfin motar da ƙarfin fitarwa na yanayi daban-daban. A cewar "Bincike da Ci Gaban Motocin Tashi da Fasahohin Maɓalli", injin jan wutar lantarki na jirgin sama ya sami damar yin ƙimar ƙarfin jikin motar fiye da 5kW/kg ta hanyar amfani da kayan kariya masu zafi mafi girma, kayan maganadisu na dindindin tare da ƙimar ƙarfin maganadisu mafi girma da kayan gini masu sauƙi. Ta hanyar inganta ƙirar tsarin lantarki na motar, kamar amfani da jerin maganadisu na Halbach, tsarin ƙarfe mara ƙarfe, naɗe waya ta Litz da sauran fasahohi, da kuma inganta ƙirar watsa zafi na motar, ana sa ran cewa ƙimar ƙarfin jikin motar zai iya kaiwa 10kW/kg a cikin 2030, kuma ƙimar ƙarfin zai wuce 13kW/kg a cikin 2035 [1].

3. Kwatanta hanyoyin lantarki masu tsabta da na haɗaka
Idan aka kwatanta da hanyar lantarki mai tsabta da hanyar haɗakarwa, daga zaɓin masana'antun da suka dace a yanzu, aikin eVTOL na cikin gida galibi ya dogara ne akan tsarin lantarki mai tsabta, wanda aka iyakance shi da yawan kuzarin batirin lithium-ion, kuma eVTOL mai ƙarancin ƙarfin fasinjoji shine mafi kyawun wurin saukar da fasahar turawa ta lantarki mai tsabta. A ƙasashen waje, wasu masana'antun sun tsara tsarin haɗakarwa a gaba, kuma sun jagoranci zagaye da yawa na gwaji da maimaitawa. Kamar yadda za a iya gani daga teburin da ke ƙasa, tsarin haɗakarwa a bayyane yake ya fi ƙarfi a cikin kusurwar juriya, kuma zai iya cimma ƙarin amfani a cikin yanayin zirga-zirgar matsakaici-tsakiya da ƙarancin tsayi a nan gaba [1].
