Aerodynamics for Pilots: The #1 Ultimate Guide for Student Pilots

Ngati mukufuna kuwuluka bwino, muyenera kumvetsetsa momwe ndege imagwirira ntchito. Ndipo izo zimayamba ndi chinthu chimodzi: aerodynamics kwa oyendetsa ndege.

Kaya mukuphunzitsa zanu Chilolezo Choyendetsa Ndege (PPL) kapena kupita ku certification yamalonda, zochitika mlengalenga ndiye maziko a chilichonse chomwe mungachite m'chipinda cha oyendera—kuyambira ulendo wanu woyamba kufikira njira zanu zadzidzidzi.

The FAA sichichita ngati chiphunzitso. Amachiyesa, amachiphunzitsa, ndipo amayembekezera kuti muzigwiritsa ntchito m’mlengalenga, osati pamapepala okha.

Bukuli limafotokoza zonse zomwe muyenera kudziwa: mphamvu zinayi zowuluka, mbali zowukira, malo osungira, kukhazikika, zotsatira zanyengo, ndi momwe zimalumikizirana ndi zanu. fufuzani.

Ngati mukufunadi kukhala woyendetsa ndege wachangu, wodzidalira - apa ndipamene kukwera kumayambira.

Kodi aerodynamics ndi chiyani? Kutanthauzira kosavuta kwa oyendetsa ndege

Pachimake, ma aerodynamics kwa oyendetsa ndege ndi okhudza kumvetsetsa momwe mpweya umayendera mozungulira ndege - komanso momwe kayendetsedwe kake kamapanga mphamvu zomwe zimawalola kuwuluka.

Sizokhudza ma equation kapena chiphunzitso chifukwa cha nthanthi. Ndi za ulamuliro. Kutembenuka kulikonse, kukwera, kutsika, ndi kutera komwe mumapanga kumayendetsedwa ndi momwe mumayendetsera bwino kayendedwe ka mpweya, kupanikizika, ndi kukana.

In maphunziro oyendetsa ndege, aerodynamics amatanthauza kudziwa momwe ndi chifukwa ndege imayankha ku zolowetsa-osati kokha chani zimatero. Mudzagwiritsa ntchito izi nthawi iliyonse mukakonza chikepe, kukonza mphepo yamkuntho, kapena pozindikira malo omwe akuyandikira.

Ganizirani izi ngati mawonekedwe osawoneka kumbuyo kwa ndege iliyonse yopambana.

Mphamvu zinayi zakuthawa - msana wa aerodynamics

Ndege iliyonse yomwe ikuyenda imakhudzidwa ndi mphamvu zinayi zofunika kwambiri za aerodynamic:

• Nyamula: Mphamvu yokwera yopangidwa ndi mapiko omwe amatsutsana ndi mphamvu yokoka. Ndi zomwe zimakusungani mumlengalenga.
• kulemera kwake: Mphamvu yokoka imakokera ndege pansi. Izi ziyenera kulinganizidwa ndi lift kuti muyende bwino.
• Kukakamira: Mphamvu yakutsogolo yopangidwa ndi injini ndi propeller, kugonjetsa kukokera.
• Kokani: Kulimbana ndi mpweya kumakankhira ndege pamene ikupita patsogolo.

Mphamvuzi sizimachita paokha—zimalumikizana mosalekeza. Kukweza kochulukira nthawi zambiri kumatanthauza kukokera kwambiri. Kulimbana ndi ma thrust drag, koma kumakhudzanso kukweza kutengera liwiro la airspeed ndi ngodya yakuukira.

Monga wophunzira woyendetsa ndege, muyenera kumvetsetsa momwe mphamvuzi zimasinthira munthawi yeniyeni-panthawi yonyamuka, kutembenuka, kukwera, ndi kutsika. Ndiwo maziko a luso la aerodynamics kwa oyendetsa ndege.

Ngongole yowukira, masitepe, ndi kutayika kokweza zidafotokozedwa

Imodzi mwa mfundo zofunika kwambiri mu aerodynamics kwa oyendetsa ndege ndikumvetsetsa angle of attack (AOA)- ndi momwe zimakhudzira mwachindunji kukweza ndi masitepe.

Engle of attack ndi mbali yapakati pa phiko la chord line ndi mphepo yapafupi. Pamene AOA ikuchulukirachulukira, momwemonso imakweza-mpaka nsonga. Mukangodutsa mbali yofunika kwambiri ya kuukira, mpweya wotuluka pamwamba pa mapiko umalekanitsidwa, kukweza kutsika kwambiri, ndipo ndege zimayima.

Woyendetsa ndege aliyense ayenera kuphunzira kuzindikira machenjezo otsalira ndikuchira msanga. Kaya mukuwuluka Cessna 172 kapena Piper Archer, mawonekedwe a aerodynamic ndi omwewo: kutsika kwambiri, kutsika. liwiro la ndege, ndi mpweya wosakwanira = kukhazikika.

FAA imafuna kuti musamangomvetsetsa lingaliro ili koma muwonetsere mukuwuluka. Kudziwa bwino mbali yakuukira sikungakambirane muzambiri za oyendetsa ndege - ndipo ndi imodzi mwamitu yoyesedwa kwambiri pa cheke cha PPL.

Kukhazikika ndi kuwongolera: Momwe ndege zimakhalira bwino

Lingaliro linanso lofunika kwambiri pa kayendedwe ka ndege kwa oyendetsa ndege ndilo kukhazikika kwa ndege—momwe ndege imakanira kuyenda mosayenera ndi kubwerera kunjira yokhazikika youluka popanda kuwongolera nthaŵi zonse.

Pali mitundu itatu yokhazikika yomwe muyenera kudziwa:

• Kukhazikika kwa nthawi yayitali (phokoso): Imayendetsedwa ndi chokhazikika chokhazikika ndi elevator.
• Kukhazikika kwapakati (mpukutu): Kutengera kapangidwe ka mapiko a dihedral.
• Kukhazikika kwamayendedwe (yaw): Yoyendetsedwa ndi chokhazikika chokhazikika ndi chowongolera.

Kusakhazikika bwino kungapangitse ndege kukhala yovuta kuigwira, makamaka pakakhala chipwirikiti kapena pakuuluka pang'onopang'ono. Monga wophunzira, muphunzira momwe mphamvu yokoka (CG) ndi kugawa kulemera zimakhudzira nkhwangwa zonse zitatu.

Malo owongolera - ma ailerons, chiwongolero, ndi elevator - ndi zida zanu zowongolera ndikuwongolera bata. M'maphunziro oyendetsa ndege, kumvetsetsa momwe machitidwewa amagwirira ntchito palimodzi ndikofunikira kuti agwire bwino komanso mayankho oyenerera pazovuta.

Mwachidule, ma aerodynamics kwa oyendetsa ndege samangokhudza zomwe zimapangitsa ndege kuwuluka-komanso zomwe zimapangitsa kuti ikhale yokhazikika komanso yosasunthika panthawi iliyonse yaulendo.

Momwe liwiro la ndege, kutalika, ndi nyengo zimakhudzira kayendedwe ka ndege

M'ndege zenizeni, ma aerodynamics kwa oyendetsa ndege samakhala opanda kanthu - amasintha ndi mfundo iliyonse ya liwiro la ndege, phazi lililonse lamtunda, komanso kusintha kulikonse kwanyengo.

Kuthamanga zimakhudza kuchuluka kwa momwe mapiko anu angapangire. Pama liwiro otsika, mumafunika ngodya yokwera kwambiri kuti mupitirize kukweza. Pakuthamanga kwambiri, kukoka kumawonjezeka kwambiri, makamaka kukoka kwa parasitic - kukukakamizani kuti muzitha kuyendetsa bwino ndikuyimitsa mosamala kwambiri.

Kutalika imagwiranso ntchito yayikulu. Pamalo okwera, mpweya umakhala wochepa thupi. Izi zikutanthauza mpweya wocheperako = kukweza pang'ono. Injini yanu imathanso kutulutsa mphamvu zochepa, zomwe zimafuna ma rolls ataliatali onyamuka komanso kuthamanga kwenikweni kwenikweni. Kumvetsetsa momwe kachulukidwe kachulukidwe imakhudzira magwiridwe antchito ndi gawo lofunikira pakuwongolera ma aerodynamics kwa oyendetsa ndege.

Weather zinthu monga kutentha, chinyezi, ndi kukameta ubweya wa mphepo zimasinthanso momwe ndege yanu imachitira. Patsiku lotentha, lachinyezi, mapiko anu amatulutsa pang'ono. Panjira zovuta, mayendedwe anu ndi kasamalidwe ka mphamvu ziyenera kusintha munthawi yeniyeni.

Mukamvetsetsa momwe chilengedwe chimakhudzira makina oyendetsa ndege, mumayamba kupanga zisankho zanzeru - osati kungotengera manambala, koma momwe ndegeyo imayendera. akumva mlengalenga.

Aerodynamics mumitundu yosiyanasiyana ya ndege

Sikuti ndege zonse zimauluka mofanana—ndipo m’pamene chidziwitso chokhudza kapangidwe kake chimakhala chofunika kwambiri pa kayendetsedwe ka ndege kwa oyendetsa ndege.

Ndege zokhala ndi mapiko apamwamba (monga Cessna 172) zimakhala zokhazikika komanso zowoneka bwino pansi, pomwe ndege zamapiko otsika (monga Piper Warrior) nthawi zambiri zimakhala ndi magwiridwe antchito abwino komanso momwe zimakhudzira pansi pakutera.

Kuwongolera pamwamba kumapangitsanso kusiyana. Ndege zokhala ndi ma stabilators (monga Piper Cherokee) zimayankha mosiyana ndi momwe zilili ndi zikepe zachikhalidwe. Ma propeller osinthasintha amakhudza kukankhira ndi kukoka pamagawo owuluka. Ngakhale mawonekedwe a mapiko - opindika motsutsana ndi amakona anayi - amasintha mawonekedwe okhazikika ndikukweza bwino.

Mukumananso ndi zida zamapangidwe monga zotchingira, zowononga, majenereta a vortex, ndi mapiko. Iliyonse mwa izi imasintha kayendedwe ka mpweya mwadala, kukweza kukweza, kuchepetsa kukoka, kapena kuwongolera kuyendetsa pang'onopang'ono.

Kuti muchite bwino ngati wophunzira woyendetsa ndege, muyenera kumvetsetsa momwe mapangidwewa amagwirizanirana ndi mfundo za kayendedwe ka ndege kwa oyendetsa ndege - chifukwa ndege sizimakhala zofanana, ndipo oyendetsa ndege anzeru amasinthasintha malinga ndi momwe akuwulukira.

Zofunikira za FAA: Aerodynamics mu maphunziro oyendetsa ndege

FAA imagwiritsa ntchito ma aerodynamics kwa oyendetsa ndege monga chidziwitso chachikulu - osati chosankha. Imayesedwa, kuwonetseredwa, ndikuwunikidwa pamlingo uliwonse wa certification, makamaka pagawo la Private Pilot License (PPL).

Mu FAA Airman Certification Standards (ACS), aerodynamics imapezeka m'zigawo zonse zoyesera ndi chidziwitso. Mukuyembekezeka kuti mumvetsetse:

• Mphamvu zinayi zakuthawa
• Ngongole ya kuukira ndi machitidwe opumira
• Zotsatira za CG, kulemera, ndi kusanja pakukhazikika
• Zoyipa za yaw, torque, ndi katundu
• Momwe zinthu zapangidwe zimakhudzira magwiridwe antchito ndi kuwongolera

Mudzawona mitu iyi pamayeso olembedwa, komanso munthawi yeniyeni mukamayendera. Woyesa angafunse momwe khola limapangidwira - kapena kukufunani kuti muwonetsere kuchira pamene mukufotokoza njira ya aerodynamic.

Uthenga wa FAA ndi womveka bwino: ngati mukufuna kuwuluka bwinobwino, muyenera kulingalira za kayendedwe ka mpweya ndi mphamvu. Izi n’zimene anthu oyendetsa ndege amayendera—kusankha zochita mwanzeru potengera zimene zikuchitika m’ndegemo, osati m’chipinda choyendera ndege mokha.

Njira zabwino zophunzirira ma aerodynamics ngati wophunzira woyendetsa ndege

Kudziwa bwino za kayendedwe ka ndege kwa oyendetsa ndege sikutanthauza kuloweza mawu aukadaulo - kumatanthauza kumvetsetsa momwe ndege imagwirira ntchito munthawi yeniyeni. Ndipo njira yabwino yochitira izi ndikuphatikiza chiphunzitso ndi kuphunzira pamanja.

Nazi zomwe zimagwira ntchito:

• Zida zowonera: Gwiritsani ntchito zoyezera ndege, mapulogalamu azithunzi, ndi mitundu ya 3D kuti muwone momwe mpweya umayendera, kukweza, kukoka, ndi kuwongolera mayendedwe.
• Mabuku ovomerezeka ndi FAA: The Ndege Flying Handbook ndi Buku la Pilot's Handbook of Aeronautical Knowledge onse amafotokoza mfundo za kayendedwe ka ndege mwatsatanetsatane-kuchokera ku gwero.
• Maphunziro apakanema pa intaneti: Maphunziro ochokera ku Sporty's, King Schools, ndi Gleim amaphwanya mfundo zovuta kukhala maphunziro ang'onoang'ono okhala ndi zithunzi zenizeni za a cockpit.
• Flashcards ndi mafunso: Gwiritsani ntchito mabanki a mafunso a FAA ndi mapulogalamu a m'manja kuti mulimbikitse matanthauzidwe, mafomula, ndi mfundo za aerodynamic mwachangu.

Chofunika kwambiri, gwirizanitsani zomwe mumaphunzira papepala ndi zomwe inu ndikumverera mumlengalenga. Pakukwera kulikonse, kutembenuka kulikonse, njira iliyonse - mudzawona ma aerodynamics a oyendetsa ndege akugwira ntchito. Mukatero, zonse zimayamba kudina.

Kutsiliza: Kudziwa bwino za kayendedwe ka ndege kumatanthauza kudziwa bwino kuuluka

Pa maphunziro oyendetsa ndege, palibe njira zazifupi-ndipo ndizowona makamaka pankhani ya aerodynamics kwa oyendetsa ndege. Sikuti kungopambana mayeso olembedwa, koma kuwuluka ndi cholinga, kuwongolera, komanso chidaliro.

Kuchokera pakukwera ndi kukokera kupita kumalo osungira ndi kuwongolera, mfundozi zimagwira ntchito nthawi iliyonse mukachoka pamsewu. Mukamawamvetsa bwino, m’pamenenso mumayamba kuuluka mwachibadwa.

Ngati mukufunadi kukhala woyendetsa ndege wotetezeka, waluso, sungani chidziwitsochi msanga. Chifukwa chakuti mphamvu ya kayendedwe ka ndege kwa oyendetsa ndege ikamveka bwino, china chilichonse m'chipinda cha okwera ndege chimayamba kumva mwachibadwa.
