Ukuhamba ngokuthe nkqo kunye nokufika (VTOL) yenye yeendlela zokuphuhlisa ii-UAVs
Ukuthatha uhambo oluthe nkqo kunye nokuma-ezona zixhobo ziphambili ezilishumi zexesha elizayo zomkhosi wase-US
Ngenxa yokuba ingathintelwa kukumka kunye neendawo zokumisa kwaye iyakwazi ukuziqhelanisa nemeko yendawo entsonkothileyo efana nokuhamba ngenqanawa kunye neentaba, iUnited States idwelise inqwelomoya yokusuka ethe nkqo kunye nokumisa njengeyona mikhosi ilishumi iphezulu yase-US.
Ukuza phezulu kwezixhobo eziphambili. Kukho iindlela ezimbini eziphambili zobugcisa zokusuka ngokuthe nkqo kunye nokumisa ii-UAV ezinamaphiko asisigxina. 1) I-Tilt-rotor UAV: yazisa ngokujikeleza
Isalathiso senkuthazo sibonelela ngokuphakanyiswa kunye nokutyhala okufunekayo kwizigaba ezibini zokusuka ngokuthe nkqo kunye nokumisa nokuya phambili. Imodeli yommeli yi-American V-22 Osprey.
Inguqulo ye-drone “Iliso leKhozi” kunye nelizwe lam i-Rainbow-10, njl. njl. 2) I-rotor esisigxina yohlobo lwephiko: ithatha iiseti ezimbini zeenkqubo zamandla, i-rotor inikezela ngokuthe nkqo.
Phakamisa, inikwe amandla yi-injini yokuqhubela phambili kwimowudi yamaphiko esisigxina, iimodeli zabameli zibandakanya izabelo zeZongheng “CW Dapeng” uthotho, iRainbow CH804D njalo njalo.
Inkqubo yokuqhubela umbane ingathatha indawo yamacandelo othungelwano ngoomatshini kunye nokwandisa ukucwangciswa kwe-rotor ethambekileyo. Ubumbeko lwe-tilt-rotor inokuqinisekisa ukuthabatha okulungileyo kokuma kunye nokufika
Ngaphantsi kwesiseko sokusebenza, ukusebenza kakuhle kwenqanaba lokuhamba ngenqwelomoya kuphuculwe, ngaloo ndlela kuthathelwe ingqalelo ukuhamba ngokuthe nkqo kunye nokukwazi ukuhla kunye noqoqosho lokuhamba ngenqanawa. Xa kuthelekiswa nokucwangciswa kwe-rotor, inokuphuculwa kakhulu
uhambo ngenqanawa. Uphando kunye nophuhliso kunye nokusetyenziswa kweteknoloji ye-rotor i-tilting isetyenziswe amashumi eminyaka, kwaye iimodeli ezifana ne-V-22 zifunyenwe kwimisebenzi ekhethekileyo kunye nezinye iimeko.
Isetyenziswa kakhulu, kodwa kusetyenziswa inkqubo yamandla emveli yokuthomalalisa inqwelomoya, indlela yokukhupha amandla enjini kunye nerotor kufuneka ibenzima kakhulu.
Amacandelo okuhanjiswa komatshini anyusa kakhulu ubunzima kunye nobunzima beqonga, kwaye abe nefuthe elithile ekuthembekeni. Ukusetyenziswa kwenkqubo yokuqhubela umbane kuyasebenza
Ukuphepha le mingcipheko ingentla, i-motor inokubekwa ngokuthe ngqo kwi-tilting wing assembly, kwaye i-motor inokuqhutyelwa ngokugqithiswa kwamandla ombane ngentambo, ngaphandle kwemfuneko yeyunithi yokuhambisa amandla.
Amacandelo, anciphisa kakhulu ubunzima besakhiwo somatshini, kunye neempawu zokugcinwa kwayo zingaqinisekiswa.
Xa kuthelekiswa ne-tilting rotor configuration, ulungelelwaniso oluxubileyo lwephiko le-rotor esisigxina lwenza lula ulwakhiwo kwaye lugweme impembelelo yamacandelo okuthamba. Rotor iphiko esisigxina ikhompawundi
I-UAV ixhotyiswe nge-propeller ye-fixed-pitch ngaphambili nangasemva kumbindi wamaphiko kumacala omabini ukuze ibonelele ngokuphakanyiswa okufunekayo ukunduluka okuthe nkqo kunye nokuhla.
Ipropeller yokuqhubela phambili ibonelela ngesantya senqanaba lokuhamba ngenqwelomoya yenqanaba lokubhabha. Kwinqanaba lokuhamba ngenqanawa elithe tye, iipropeller ezi-4 kwindawo yephiko ziya kumiswa kwaye zilungiswe.
Kwindawo yokuchasana okuncinci, ngaloo ndlela ukunciphisa ukuchasana ngexesha lokuhamba kwinqanaba. Ulungelelwaniso lwe-hybrid luthathela ingqalelo ukuhamba ngokuthe nkqo kunye nokusebenza kokuma kwenqwelomoya yeenqwelomoya ezininzi kunye neqinileyo.
Xa kuthelekiswa nokucwangciswa kwe-tilt-rotor, i-aircraft ye-fixed-wing ineempawu zezinga eliphezulu lokuhamba. Ubume be-hybrid bunesakhiwo esilula kwaye akukho nxalenye yokuthambeka. Okwesibini, lungisa
Ukuhlalisana kwephiko kunye nesakhiwo se-rotor ngokwenene luhlobo lwe-compromise. Ezi zimbini ziya kuchaphazela omnye nomnye. Ngakolunye uhlangothi, isakhiwo sikhulu ngobunzima, kwaye kwelinye icala, ukusebenza kakuhle kulinganiselwe.
Ngexesha lokuhamba okuthe nkqo kunye nenqanaba lokuhla, indawo enkulu yephiko iya kwandisa ukuhamba kunye nokuchasana nokuhla; kwinqanaba le-flight phase, i-rotor iya kwandisa ukuchasana. Ukuze kulinganiswe le mpembelelo,
I-propeller inokumiswa kwaye indawo inokulungiswa ngexesha lesigaba sendiza.
