Vertical take-off and landing (VTOL) is one of the development trends of UAVs
Vertical take-off and landing-the top ten key future equipment of US cov tub rog
Vim tias nws tsis txwv los ntawm kev tawm mus thiab tsaws qhov chaw thiab tuaj yeem hloov mus rau thaj chaw nyuaj xws li kev taug kev thiab toj siab, Tebchaws Meskas tau teev npe ntsug nqa tawm thiab tsaws dav hlau raws li kaum Asmeskas tub rog.
Los rau saum cov khoom siv tseem ceeb. Muaj ob txoj hauv kev tseem ceeb rau kev nqa tawm ntsug thiab tsaws ruaj-tis UAVs. 1) Tilt-rotor UAV: rotating
Cov kev taw qhia kev txhawb nqa muab lub nqa thiab lub zog xav tau rau ob theem ntawm ntsug nqa tawm thiab tsaws thiab rau pem hauv ntej. Tus qauv sawv cev yog American V-22 Osprey.
Lub drone version “Eagle Eye” thiab kuv lub teb chaws tus Zaj sawv-10, thiab lwm yam. 2) Rotor tsau tis compound hom: txais ob pawg ntawm lub zog, lub rotor muab ntsug
Nqa, siv los ntawm lub cav propulsion nyob rau hauv tis-tis hom, cov qauv sawv cev suav nrog Zongheng qhia “CW Dapeng” series, Zaj sawv CH804D thiab lwm yam.
Lub tshuab hluav taws xob propulsion tuaj yeem hloov cov khoom siv sib txuas sib txuas thiab ua kom zoo dua qhov kev teeb tsa ntawm tilting rotor. Lub qaij-rotor configuration tuaj yeem ua kom zoo ntsug nqa tawm thiab tsaws
Raws li qhov ua tau zoo ntawm kev ua tau zoo, kev ua tau zoo ntawm qib davhlau tau txhim kho, yog li coj mus rau hauv tus account ntsug nqa tawm thiab tsaws muaj peev xwm thiab kev lag luam caij nkoj. Piv nrog rau rotor configuration, nws tuaj yeem txhim kho zoo heev
kev caij nkoj. Kev tshawb fawb thiab kev tsim kho thiab kev siv tilting rotor tshuab tau siv ntau xyoo lawm, thiab cov qauv xws li V-22 tau txais hauv kev ua haujlwm tshwj xeeb thiab lwm yam xwm txheej.
Kev siv dav dav, tab sis siv cov khoom siv hluav taws xob ib txwm siv tilt rotor aircraft, nws lub cav fais fab tso zis mechanism thiab rotor yuav tsum muaj qhov nyuaj heev.
Cov khoom siv hluav taws xob sib kis tau nce qhov nyuaj thiab qhov hnyav ntawm lub platform, thiab muaj qee yam cuam tshuam rau kev ntseeg tau. Kev siv hluav taws xob propulsion system yog siv tau
Txhawm rau kom tsis txhob muaj kev pheej hmoo saum toj no, lub cev muaj zog tuaj yeem muab tso ncaj qha rau ntawm lub tilting tis sib dhos, thiab lub cev muaj zog tuaj yeem tsav tau los ntawm kev sib kis ntawm hluav taws xob hluav taws xob los ntawm cov kab hluav taws xob, tsis tas yuav tsum muaj lub zog xa hluav taws xob.
Qhov chaw, zoo heev txo cov complexity ntawm cov neeg kho tshuab qauv, thiab nws cov yam ntxwv txij nkawm tuaj yeem lav.
Piv nrog rau tilting rotor configuration, qhov sib xyaw configuration ntawm lub rotor tis ruaj yooj yim rau cov qauv thiab tsis txhob cuam tshuam cov tilting Cheebtsam. Rotor tsau tis compound
Lub UAV tau nruab nrog lub tshuab hluav taws xob ruaj khov nyob rau pem hauv ntej thiab nram qab ntawm nruab nrab ntawm cov tis ntawm ob sab los muab cov nqa yuav tsum tau rau ntsug nqa tawm thiab tsaws.
Lub propulsion propeller muab thrust thaum lub sij hawm caij nkoj ntawm qib ya. Nyob rau hauv kab rov tav cruise theem, 4 propellers ntawm lub tis txoj hauj lwm yuav tsum nres thiab tsau.
Nyob rau hauv txoj hauj lwm ntawm qhov tsawg kawg nkaus tsis kam, yog li txo qhov kev tiv thaiv thaum lub sij hawm ya davhlau. Lub hybrid configuration yuav siv sij hawm mus rau hauv tus account lub ntsug take-off thiab tsaws kev ua tau zoo ntawm lub multi-rotor aircraft thiab cov khoom.
Piv nrog rau lub qaij-rotor configuration, taag-tis aircraft muaj cov yam ntxwv ntawm high-efficiency theem davhlau. Lub hybrid configuration muaj ib tug yooj yim qauv thiab tsis tilting qhov chaw. Thib ob, kho
Lub coexistence ntawm tis thiab lub rotor qauv yog tiag tiag ib hom kev sib haum xeeb. Ob leeg yuav cuam tshuam ib leeg. Ntawm ib sab, cov qauv yog loj nyob rau hauv loj, thiab ntawm qhov tod tes, cov efficiency yog txwv.
Thaum lub sij hawm ntsug nqa tawm thiab tsaws theem, thaj tsam loj ntawm lub tis yuav ua rau kom muaj kev tawm tsam thiab tsaws; nyob rau hauv theem ya davhlau theem, lub rotor yuav ua rau kom muaj zog. Yuav kom sib npaug qhov kev cuam tshuam no,
Lub kiv cua tuaj yeem nres thiab txoj haujlwm tuaj yeem kho tau thaum lub sijhawm ya davhlau theem.
