Lisebelisoa tsa Phokotso ea Propeller
Lisebelisoa tsa phokotso ea propeller ke karolo ea bohlokoa sefofaneng se nang le enjine ea piston kapa enjine ea turboprop. Mosebetsi oa eona o ka sehloohong ke ho fokotsa lebelo le phahameng la ho potoloha ha enjene ho lebelo le tlase le loketseng ho khanna propeller hantle. Phokotso ena ea lebelo e lumella propeller ho fetolela matla a enjene hore e be matla a maholo, ho ntlafatsa ts'ebetso ea mafura le ho fokotsa lerata.
Thepa e fokotsang propeller e na le likere tse 'maloa, ho kenyeletsoa gire ea ho khanna e hoketsoeng le crankshaft ea enjene le lisebelisoa tse khannoang tse hokelletsoeng moqomong oa propeller. Li-gear tsena hangata ke li-helical kapa spur gears 'me li etselitsoe ho hokahana hantle ho fetisa matla ka nepo.
Sefofaneng se tsamaisoang ke piston, karo-karolelano ea lisebelisoa tsa phokotso hangata e ka ba 0.5 ho isa ho 0.6, ho bolelang hore propeller e potoloha hoo e ka bang halofo kapa ho feta halofo ea lebelo la enjene. Phokotso ena ea lebelo e lumella propeller ho sebetsa ka mokhoa o nepahetseng hantle, ho hlahisa lerata le lerata le sisinyehang.
Sefofaneng sa turboprop, lisebelisoa tsa phokotso li sebelisoa ho ts'oants'a tlhahiso ea lebelo le phahameng la enjene ea turbine ea khase le lebelo le tlase la potoloho le hlokoang ke propeller. Lisebelisoa tsena tsa phokotso li lumella lienjineri tsa turboprop hore li sebetse hantle ho pholletsa le lebelo le pharalletseng, li etsa hore li tšoanelehe bakeng sa mefuta e fapaneng ea lifofane le misio.
Ka kakaretso, lisebelisoa tsa phokotso ea propeller ke karolo ea bohlokoa lits'ebetsong tsa ho tsamaisa lifofane, tse lumellang lienjine ho sebetsa hantle le ka khutso ha li ntse li fana ka sepheo se hlokahalang bakeng sa sefofane.
Lisebelisoa tsa ho Lulisa
Lisebelisoa tsa ho theoha ke karolo ea bohlokoa ea sefofane se se lumellang ho tloha, ho lula le tekesi fatše. E na le mabili, li-struts, le mekhoa e meng e tšehetsang boima ba sefofane le ho fana ka botsitso nakong ea ts'ebetso ea fatše. Lisebelisoa tsa ho theola sefofane hangata lia khutlisetsoa morao, ho bolelang hore li ka phahamisetsoa ka har'a fuselage ea sefofane nakong ea sefofane ho fokotsa ho hula.
Sistimi ea lisebelisoa tsa ho lulisa e kenyelletsa likarolo tse 'maloa tsa bohlokoa, e' ngoe le e 'ngoe e sebetsa mosebetsi o itseng:
Main Landing Gear: Lisebelisoa tse ka sehloohong tsa ho theola li fumaneha ka tlas'a mapheo 'me li tšehetsa boholo ba boima ba sefofane. E na le lebili le le leng kapa a mangata a khomaretsoeng ho li-struts tse theohelang tlase ho tloha mapheong kapa fuselage.

Lisebelisoa tsa ho fokotsa turboprop
Lisebelisoa tsa phokotso ea turboprop ke karolo ea bohlokoa lienjineng tsa turboprop, tse sebelisoang hangata lifofaneng ho fana ka propulsion. Lisebelisoa tsa phokotso li na le boikarabello ba ho fokotsa tlhahiso ea lebelo le phahameng la turbine ea enjene ho lebelo le tlase le loketseng ho khanna propeller hantle. Mona ke lintlha tse ling tsa bohlokoa tsa lisebelisoa tsa ho fokotsa turboprop:
Karo-karolelano ea Phokotso: Lisebelisoa tsa phokotso li fokotsa ho potoloha ka lebelo le phahameng la turbine ea enjene, e ka fetang mashome a likete a li-revolutions ka motsotso (RPM), ho ea lebelo le tlase le loketseng propeller. Karolelano ea phokotso hangata e lipakeng tsa 10:1 le 20:1, ho bolelang hore propeller e potoloha ho karolo ea leshome ho isa ho mashome a mabeli a lebelo la turbine.
Planetary Gear System: Li-gear tse fokotsang Turboprop hangata li sebelisa sistimi ea lipolanete, e nang le lisebelisoa tsa letsatsi tse bohareng, likere tsa polanete le lisebelisoa tsa selikalikoe. Sistimi ena e lumella ho fokotsa li-gear tse kopaneng le tse sebetsang hantle ha ho ntse ho ajoa mojaro ka ho lekana har'a likere.
High-Speed Input Shaft: Lisebelisoa tsa phokotso li hokahane le shaft e tsoang ka lebelo le phahameng ea turbine ea enjine. Shaft ena e potoloha ka lebelo le phahameng mme e tlameha ho raloa ho mamella likhatello le mocheso o hlahisoang ke turbine.
Low-Speed Output Shaft: The shaft e hlahisoang ea gear ea phokotso e hokahane le propeller mme e potoloha ka lebelo le tlase ho feta shaft ea ho kenya. Shaft ena e fetisetsa lebelo le torque e fokotsehileng ho propeller, e e lumellang ho hlahisa matla.
Li-bearings le Lubrication: Li-gear tsa phokotso tsa Turboprop li hloka li-bearings tsa boleng bo holimo le lits'ebetso tsa lubrication ho netefatsa ts'ebetso e bonolo le e tšepahalang. Li-bearings li tlameha ho mamella lebelo le meroalo e phahameng, athe sistimi ea lubrication e tlameha ho fana ka lubrication e lekaneng ho fokotsa khohlano le ho khathala.
