Chidziwitso cha Airspeed Indicator
Chizindikiro cha liwiro la ndege, chomwe ndi chida chofunikira kwambiri pa malo oyendera ndege iliyonse, chimayesa liwiro la ndege poyerekezera ndi momwe akuzungulira. Imagwira ntchito potengera kupanikizika kwapakati pa kukakamiza kwa static kunja kwa ndege ndi kuthamanga kwamphamvu komwe kuyezedwa ndi chubu la pitot. Kupanikizika kosiyana kumeneku kumasinthidwa kukhala kuwerenga kwachangu.
Chizindikiro cha liwilo la ndege ndi chida chachikulu cha woyendetsa ndege kuti asayang'anirenso ndege. Ndiwofunikanso kwambiri pokonzekera ndi kuyendetsa ndege, zomwe zimapereka chidziwitso chamtengo wapatali chokhudza momwe ndegeyo imagwirira ntchito m'mikhalidwe yosiyanasiyana.
Chizindikiro cha airspeed si chida chimodzi chokha koma kuphatikiza zigawo zingapo zomwe zimagwira ntchito pamodzi. Zinthuzi zikuphatikiza chubu la pitot, doko lokhazikika, ndi chizindikirocho, zomwe zimapereka kuwerengera kolondola komanso kwachangu kwa woyendetsa.
Kumvetsetsa Kufunika kwa Chizindikiro cha Airspeed mu Ndege
Chizindikiro cha airspeed ndichofunikira kuti muyende bwino komanso kuti muyende bwino. Imauza woyendetsa ndegeyo liwiro limene ndegeyo ikupita mumlengalenga, mfundo zofunika kwambiri kuti inyamuka, kuyenda, ndi kutera.
Popanda izi zofunika chida, oyendetsa ndegewo sangathe kudziwa bwinobwino liwiro lawo, zomwe zingabweretse mavuto aakulu monga kuimirira kapena kupitirira malire a mmene ndegeyo imayendera. Choncho, chizindikiro cha airspeed chimagwira ntchito yofunika kwambiri pachitetezo cha ndege.
Komanso, kumvetsetsa mitundu yosiyanasiyana ya liwiro la ndege ndikofunikira kuti ndege ziziyenda bwino. Maulendo apamlengalenga awa akuphatikizapo Indicated Airspeed (IAS), Calibrated Airspeed (CAS), True Airspeed (TAS), ndi Ground Speed (GS). Liwiro lililonse la maulendowa limagwira ntchito inayake ndipo ndilofunika kwambiri pamagawo osiyanasiyana owuluka komanso momwe zinthu zilili.
Kuwona Mayendedwe: Chidule
Chizindikiro cha airspeed chimayesa mitundu inayi yothamanga: Indicated Airspeed (IAS), Calibrated Airspeed (CAS), True Airspeed (TAS), ndi Ground Speed (GS). Komabe, palinso mitundu iwiri yowonjezerapo, Equivalent Airspeed (EAS) ndi Mach Number (M), yomwe imagwiritsidwa ntchito pazochitika zenizeni za ndege, makamaka paulendo wothamanga kwambiri komanso wokwera kwambiri.
IAS ndiye kuwerenga kobiriwira, kosakonzedwa komwe kumawonetsedwa pa chizindikiro cha airspeed, pomwe CAS ndi IAS yokonzedwa chifukwa cha zolakwika za zida ndi kukhazikitsa. TAS ndi CAS yosinthidwa kuti ikhale yokwera komanso kutentha, ndipo GS ndi liwiro lenileni la ndege pamtunda.
EAS ndi liwiro la ndege panyanja lomwe lingapangitse kuthamanga kwamphamvu kofanana ndi momwe ndege ikuuluka, ndipo Mach Number ndi chiŵerengero cha liwiro la ndege ndi liwiro la mawu. Kumvetsetsa maulendo asanu ndi limodziwa n'kofunika kwambiri kuti oyendetsa ndege athe kutanthauzira molondola momwe akuwerengera komanso kupanga zisankho zoyenera panthawi ya ndege.
Kuzama Kwambiri: Kuwonetsa Airspeed (IAS)
IAS ndiye liwiro lomwe limawerengedwa mwachindunji kuchokera pa chizindikiro cha airspeed. Ndiwo mtundu wowongoka kwambiri wa liwiro la ndege, kuwonetsa kusiyana kwapakati pakati pa kuthamanga kwa static ndi pitot. Komabe, IAS imayang'aniridwa ndi zolakwika za zida ndi malo, kupangitsa kuti ikhale yosalondola nthawi zina.
Pamalo otsika komanso kuthamanga kwanthawi zonse, IAS imatha kupereka chithunzithunzi cholondola cha momwe ndegeyo ikugwirira ntchito. Komabe, pamene ndege ikukwera, mphamvu ya mpweya imachepa, zomwe zingapangitse IAS kukhala yodalirika.
Ngakhale zili ndi malire, IAS ndiyothamanga kwambiri kwa oyendetsa ndege. Amagwiritsidwa ntchito pochepetsa kuthamanga kwa ndege komwe kumapezeka mu buku lothandizira ndege, monga kuthamanga kwa khola, kuthamanga kwapamwamba kwambiri, ndipo osapitirira liwiro. Chifukwa chake, kumvetsetsa ndikutanthauzira IAS molondola ndikofunikira kuti ndege ziziyenda bwino.
Kumvetsetsa Calibrated Airspeed (CAS)
CAS ndi IAS yokonzedwa chifukwa cha zolakwika za zida ndi malo. Zolakwa izi zikhoza kubwera kuchokera kuzinthu zosiyanasiyana, kuphatikizapo kuyika kwa pitot tube, kutalika, ndi kusiyana kwa kutentha, pakati pa ena. CAS imapereka chithunzi cholondola cha liwiro la ndege pamlengalenga kuposa IAS yokha.
Kuti awerengetsere CAS, oyendetsa ndege amagwiritsa ntchito matebulo owongolera omwe ali m'mabuku oyendetsa ndege. Matebulowa amalola woyendetsa ndege kudziwa zosintha zoyenera ku IAS potengera momwe ndege ikuyendetsedwera.
Ngakhale kuti CAS imafuna mawerengedwe owonjezera, imapereka chithunzithunzi cholondola cha liwiro lenileni la ndege mumlengalenga, ndikupangitsa kuti ikhale chida chamtengo wapatali kwa oyendetsa ndege. Ndikofunikira kwambiri paulendo wothamanga kwambiri, pomwe zolakwika za zida zimatha kukhudza kwambiri kulondola kwa IAS.
Kufunika kwa True Airspeed (TAS)
TAS ndiye liwiro lenileni la ndegeyo malinga ndi momwe ikuwulukira. Ndi CAS yosinthidwa kuti isinthe kachulukidwe ka mpweya chifukwa cha kutalika ndi kusiyanasiyana kwa kutentha. TAS ndiyofunikira pakukonza ndi kuyendetsa ndege, chifukwa imakhudza momwe ndege imagwirira ntchito komanso kagwiritsidwe ntchito kamafuta.
Popeza TAS imawerengera kusintha kwa kachulukidwe ka mpweya, imapereka muyeso wolondola kwambiri wa liwiro la ndege kuposa IAS kapena CAS, makamaka pamalo okwera. Komabe, sizimawerengera liwiro la mphepo ndi komwe akupita, zomwe zingakhudze kwambiri liwiro lenileni la ndegeyo pamtunda.
Ngakhale izi zili ndi malire, TAS ndi gawo lofunikira powerengera liwiro la pansi ndi kuyerekeza nthawi yomwe ili panjira, zomwe zimapangitsa kukhala chida chofunikira pokonzekera ndi kuyendetsa ndege.
Momwe Kuthamanga Kwapansi (GS) Kumakhudzira Ndege
GS ndiye liwiro lenileni la ndege pamtunda. Ndi TAS yosinthidwa chifukwa cha liwiro la mphepo ndi mayendedwe. GS ndiyofunikira kwambiri pakuyendetsa ndi kukonzekera ndege, chifukwa imatsimikizira nthawi yomwe ndegeyo imayenera kufika komwe ikupita.
Ngati ndegeyo ikuuluka ndi mphepo yamchira, GS yake idzakhala yapamwamba kuposa TAS, zomwe zimalola kuti ifike kumene ikupita mofulumira. Mosiyana ndi zimenezi, ngati ndege ikuwulukira ku mphepo yamkuntho, GS yake idzakhala yotsika kuposa TAS, ndikuwonjezera nthawi yoyendayenda.
Ngakhale kuti oyendetsa ndege sangathe kuwongolera GS, amatha kugwiritsa ntchito mwayi wawo posintha njira yawo yowulukira kuti apeze mwayi wamphepo yabwino. Chifukwa chake, kumvetsetsa GS ndi momwe imakhudzira kuthawira ndikofunikira pakukonzekera bwino komanso kogwira mtima ndege.
Ubale pakati pa IAS, CAS, TAS, ndi GS
IAS, CAS, TAS, ndi GS zonse ndi zolumikizana, iliyonse ikuyimira mbali ina ya liwiro la ndege. IAS ndiye kuwerenga mwachangu, pomwe CAS imakonza zowerengera izi chifukwa cha zolakwika za zida ndi kukhazikitsa. TAS imasinthanso CAS pakusintha kwa kachulukidwe ka mpweya chifukwa cha kutalika ndi kusiyanasiyana kwa kutentha, ndipo GS ndi TAS yosinthidwa kuti igwirizane ndi liwiro la mphepo ndi mayendedwe.
Liwiro lililonse la maulendowa limagwira ntchito inayake ndipo ndi lofunika kwambiri pamagawo osiyanasiyana owuluka. Komabe, zonsezi ndi mbali ya chithunzi chachikulu, zomwe zimapatsa woyendetsa ndegeyo kumvetsetsa bwino momwe ndegeyo ikugwirira ntchito komanso kuwathandiza kupanga zisankho mozindikira panthawi ya ndege.
Kumvetsetsa kugwirizana pakati pa maulendo anayiwa n'kofunika kwambiri kwa woyendetsa ndege aliyense. Zimawathandiza kuti azitha kutanthauzira molondola kuwerengera kwa zizindikiro za airspeed ndikuyendetsa ndege yawo mosamala komanso moyenera.
Nkhani Zodziwika ndi Maupangiri Othetsera Mavuto a Zizindikiro za Airspeed
Monga chida chilichonse, zizindikiro za airspeed zimatha kukumana ndi zovuta zomwe zingakhudze kulondola ndi kudalirika kwawo. Mavuto omwe amapezeka nthawi zambiri amaphatikizira kutsekeka kwa pitot chubu kapena doko lokhazikika, kulephera kwa zida, ndi zolakwika zamasanjidwe.
Ngati chizindikiro cha airspeed sichikuyenda bwino, chingayambitse kuwerengera molakwika, zomwe zingathe kusokoneza chitetezo cha ndege. Chifukwa chake, ndikofunikira kuti oyendetsa ndege aziyang'ana pafupipafupi zizindikiro za liwiro la ndege ngati ali ndi vuto lililonse ndikuwongolera ngati kuli kofunikira.
Kuyang'ana ndege isanakwane nthawi zonse kuyenera kuphatikizapo kuyang'ana kwa pitot chubu ndi doko lokhazikika ngati kutsekeka kapena kuwonongeka kulikonse. Akuuluka, oyendetsa ndege amayenera kuyang'ana pafupipafupi zizindikiro zawo zakuthamanga kwa ndege ndi zida zina ngati pali kusiyana kulikonse. Ngati chizindikiro cha airspeed chikuganiziridwa kuti ndi cholakwika, chiyenera kutumizidwa kapena kusinthidwa mwamsanga.
