Kana iwe uchida kubhururuka zvakanaka, unofanirwa kunzwisisa kuti ndege inoshanda sei. Uye izvo zvinotanga nechinhu chimwe: aerodynamics yevatyairi.
Kunyangwe iwe uri kudzidzira yako Yakavanzika Pilot License (PPL) kana kuenda kune chitupa chekutengesa, aerodynamics ndihwo hwaro hwezvese zvauchaita muimba yevatyairi—kubva parwendo rwako rwekutanga kuenda kunzira dzako dzechimbichimbi.
Iyo FAA haibate sedzidziso. Vanoiedza, vanoidzidzisa, uye vanotarisira kuti muishandise—mumhepo, kwete papepa chete.
Gwaro iri rinopaza zvese zvaunoda kuziva: iwo masimba mana ekubhururuka, kona yekurwisa, matanda, kugadzikana, mamiriro ekunze, uye kuti zvese zvinobatana sei musimba rako. checkride.
Kana uchida kuva mutyairi wendege anopinza, ane chivimbo—apa ndipo panotangira kusimudza ndege.
Chii chinonzi aerodynamics? Tsanangudzo iri nyore yevatyairi vendege
Pakati payo, aerodynamics yevatyairi ndeyekunzwisisa kuti mweya unofamba sei uchitenderedza ndege - uye kuti kufamba uku kunogadzira sei masimba anoirega ichibhururuka.
Hazvisi zveequation kana dzidziso nekuda kwedzidziso. Zviri pamusoro pekutonga. Kwese kutendeuka, kukwira, kudzika, uye kumhara kwaunoita kunotongwa nemabatiro aunoita mafambiro emhepo, kudzvanywa, uye kuramba.
In kudzidziswa kwekutyaira, aerodynamics zvinoreva kuziva sei uye sei ndege inopindura kune zvinopinza-kwete chete chii zvinoita. Iwe unozoshandisa izvi pese paunocheka lifti, kugadzirisa kuyambuka mhepo, kana kuziva danga riri kuuya.
Funga nezvayo sechimiro chisingaoneki chiri kumashure kwese kwese kwakabudirira kubhururuka.
Iwo mana masimba ekubhururuka - musana weaerodynamics
Imwe neimwe ndege inofamba inobatwa neina yakakosha aerodynamic masimba:
- Simudza: Simba rinokwira kumusoro rinogadzirwa nemapapiro anopikisa giravhiti. Ndiro rinokuita kuti ugare uri mumhepo.
- Weight: Simba regiravhiti richikwevera ndege pasi. Izvi zvinofanirwa kuenzaniswa nekusimudzwa kuti uchengetedze kubhururuka kwakadzika.
- Kukurudzira: Simba remberi rinogadzirwa neinjini uye propeller, kukunda kudhonza.
- Kweva: Mhepo inopikisa ichisunda ndege iyo ichienda mberi.
Aya masimba haaite ari ega — anogara achipindirana. Kuwedzera kusimudza kunowanzoreva kukweva kwakawanda. Thrust fights drag, asi zvinokanganisawo kusimudza zvichienderana nekumhanya kwemhepo uye kona yekurwisa.
Semutyairi wendege, unofanirwa kunzwisisa kuti masimba aya anochinja sei munguva chaiyo-panguva yekusimuka, kutendeuka, kukwira, uye kudzika. Ndiwo hwaro hwekugona kufambisa ndege kune vatyairi vendege.
Angle yekurwisa, matanda, uye kusimudza kurasikirwa kwakatsanangurwa
Imwe yemisimboti yakakosha muaerodynamics yevatyairi vendege kunzwisisa angle yekurwisa (AOA)-uye kuti zvinokanganisa sei kusimudza uye zviteshi.
Angle of attack ikona iri pakati pewing's chord line nemhepo inoenderana. Sezvo AOA ichiwedzera, saka inosimudza-kusvika padanho. Paunenge uchinge wapfuura iyo yakakosha kona yekurwiswa, kuyerera kwemhepo pamusoro pebapiro kunopatsanurwa, kusimudza madonhwe kubva zvakanyanya, uye zviteshi zvendege.
Wese mudzidzi mutyairi wendege anofanirwa kudzidza kuziva yambiro yekumira uye kupora nekukurumidza. Kunyangwe iwe uri kubhururuka Cessna 172 kana Piper Archer, maitiro aerodynamic akafanana: yakawandisa nzwi, yakaderera. airspeed, uye kusakwana kwemhepo inoyerera = kugadzika.
Iyo FAA inoda kuti iwe usangonzwisisa pfungwa iyi chete asi kuiratidza mukubhururuka. Mastering angle yekurwiswa haigone kutaurirana mune aerodynamics yevatyairi-uye ndeimwe yemisoro yakaedzwa zvakanyanya pane PPL cheki.
Kugadzikana uye kutonga: Kuti ndege dzinogara dzakadzikama sei
Imwe pfungwa inokosha muaerodynamics yevatyairi kugadzikana kwendege - kuti ndege inodzivisa sei kufamba kusingadiwi uye inodzokera kunzira yakadzikama yekubhururuka pasina kupindira kwekutonga nguva dzose.
Kune marudzi matatu ekugadzikana aunofanira kuziva:
- Longitudinal kugadzikana (pitch): Inodzorwa neyakachinjika stabilizer uye elevator.
- Lateral kugadzikana (roll): Inopesvedzerwa nedihedral bapiro dhizaini.
- Directional kugadzikana (yaw): Inotungamirirwa neyakagadzika stabilizer uye rudder.
Kusagadzikana zvakanaka kunogona kuita kuti ndege inonetsa kubata, kunyanya mumhirizhonga kana pakubhururuka zvishoma. Semudzidzi, iwe uchadzidza kuti pakati pesimba rinokwevera zvinhu pasi (CG) uye kugovera huremu zvinokanganisa sei ese matatu mbezo.
Kudzora nzvimbo-ailerons, rudder, uye elevator-ndiwo maturusi ako ekuchengetedza uye kugadzirisa kugadzikana. Mukudzidziswa kwendege, kunzwisisa kuti masisitimu aya anoshanda pamwechete sei kwakakosha pakubata kwakachengeteka uye mhinduro dzakakodzera kumamiriro ekugumbuka.
Muchidimbu, aerodynamics yevatyairi vendege haisi yekuti chii chinoita kuti ndege ibhururuke - zvakare nezve izvo zvinoita kuti irambe yakasimba uye ichidzoreka muchikamu chese chekubhururuka.
Kumhanya kwemhepo, kureba, uye mamiriro ekunze zvinokanganisa aerodynamics
Mundege yepasi-chaiyo, aerodynamics yevatyairi haigare munzvimbo isina chinhu-inoshanduka nechero pfundo rekumhanya kwemhepo, tsoka dzese dzekukwira, uye kwese kushanduka kwemamiriro ekunze.
Yakamhanya nemhepo zvinokanganisa zvakananga kuti ingani kusimudza mapapiro ako anogona kugadzira. Pakumhanya kwakadzika, unoda kona yepamusoro yekurwisa kuchengetedza kusimudza. Pakumhanya kwepamusoro, kudhonza kunowedzera zvakanyanya-kunyanya parasitic kudhonza-kunokumanikidza kubata throttle uye kudzika zvakanyanya.
Altitude inoita basa guru zvakare. Pakakwirira, mhepo inova mutete. Izvi zvinoreva mweya wakadzikira zvishoma = kusimudza zvishoma. Injini yako inogonawo kuburitsa simba shoma, ichida kureba kusimuka uye kukwira kwechokwadi airspeeds. Kunzwisisa kuti density altitude inokanganisa sei kuita chikamu chakakosha chekuziva aerodynamics yevatyairi.
mamiriro okunze zvinhu zvakaita setembiricha, hunyoro, uye shear yemhepo zvakare zvinoshandura maitiro endege yako. Pazuva rinopisa, rine hunyoro, bapiro rako rinogadzira zvishoma kusimudza. Panzira dzinotyisa, kukwirira kwako uye kutonga kwesimba kunofanirwa kuchinjika munguva chaiyo.
Kana iwe uchinzwisisa kuti nharaunda inokanganisa sei ma mechanics ekubhururuka, unotanga kuita sarudzo dzakangwara-kwete chete zvichibva panhamba, asi pamabatiro anoita ndege. anonzwa mumhepo.
Aerodynamics mumagadzirirwo akasiyana endege
Hadzisi dzese ndege dzinobhururuka zvakafanana-uye ndipo apo ruzivo rwekugadzira-chaiyo runova rwakakosha mune aerodynamics yevatyairi.
Ndege dzepamusoro-soro (seCessna 172) dzinowanzova nekudzikama kwakawanda uye kuoneka zviri nani pasi, nepo ndege-yakadzika-mapapiro (sePiper Warrior) inowanzova nekuita zviri nani mupumburu uye maitiro epasi pakumhara.
Kudzora pamusoro pekugadzirwa kunoitawo mutsauko. Ndege dzine ma stabilators (sePiper Cherokee) dzinopindura zvakasiyana-siyana mukukwirira kune dziye dzine zvikwiriso zvechinyakare. Variable-pitch propellers inokanganisa kusundira uye kudhonza mumatanho ekubhururuka. Kunyangwe chimiro chebapiro - tapered vs rectangular - inoshandura hunhu hwekumira uye nekusimudza hunyanzvi.
Iwe zvakare uchasangana nedhizaini maficha senge flaps, spoilers, vortex jenareta, uye mapapiro. Imwe neimwe yeiyi inoshandura mafambiro emhepo nemaune, inosimudzira kusimudza, kuderedza kudhonza, kana kunatsiridza kudzora nekumhanya kunononoka.
Kuti ubudirire semutyairi wendege, unofanirwa kunzwisisa kuti zvinhu zvekugadzira izvi zvinodyidzana sei nemisimboti yeaerodynamics yevatyairi vendege-nekuti ndege hadziite zvese zvakafanana, uye vatyairi vakangwara vanochinja zvinoenderana nezvavari kubhururuka.
