Modzidabwa momwe chizindikiro chanu cha airspeed chimagwirira ntchito? Yankho lake likupezeka m'dongosolo lapadera lotchedwa piot-static system, yomwe imayeza mphamvu ya mpweya yamphongo ndi kuyifanana nayo kuti iwonetsere kuthamanga kwa ndegeyo mlengalenga. Ndipo si zonse zomwe zimakuuzani. Momwemonso mpweya wa mpweya umatipatsa ife kutali ndikutiuza ife momwe ife tikukwera mofulumira kapena kutsika mu mapazi pa miniti. Chipangizochi chimapatsa mphamvu zida zitatu zoyendetsa ndege : Airspeed indicator , altimeter , ndi vertical speed indicator .
Zida
- Pitot Tube ndi Line : Phukusi la pitot ndi chipangizo chooneka ngati L chomwe chili kunja kwa ndege yomwe imagwiritsidwa ntchito poyeza airspeed. Ili ndi titsegu kakang'ono kutsogolo kwa chubu kumene mpweya wamphepete mwa mpweya (kuthamanga kwa mphamvu) umalowa mu chubu ndi kutseka dzenje kumbuyo kwa chubu. Mitundu ina yomwe imatha kutentha kwambiri mkati mwa chubu yomwe imalepheretsa ayezi kutsegula mpweya kapena kutaya dzenje.
- Port (Static) (Static Port) (s) ndi Lines : Phokoso lamtunda ndiloling'ono kolowera mpweya, kawirikawiri amakhala pambali pa ndege, kumenyana ndi fuselage. Khomo lolimba limayendera mpweya wolimba (wosasunthika) wa mpweya, umene umadziwikanso kuti mphamvu yozungulira kapena kupanikiza kwapakati. Ndege zina zili ndi doko imodzi yokhala ndi sitima imodzi ndipo ndege zina zimakhala ndi doko linalake ngati pali imodzi kapena zingapo zotsekedwa.
- Zida : Chombo cha stot-static chimaphatikizapo zipangizo zitatu: Chizindikiro cha airspeed, altimeter, ndi chowonekera chofulumira. Mzere wokhazikika umagwirizanitsa ndi zipangizo zonse zitatu ndi mpweya wa mpweya wochokera ku phula chubu yomwe imagwirizanitsidwa ndi chizindikiro chokha cha airspeed.
- Mbali Yoyamba ya Static (ngati idaikidwa) : Chiwombankhanga pamalo ogwidwa ndege chimagwira ntchito ina yotchedwa static port pamene chochitikacho chimakhala chachikulu. Kugwiritsira ntchito njira ina yosakanikiranayo kungapangitse kuwerengera kolakwika pang'ono pa zida, popeza kukanika mu cabin kukhoza kumakhala kosavuta kusiyana ndi madoko akuluakulu amtunda omwe amayenda kumtunda.
Ntchito Yachizolowezi
Phokoso la pitot limagwira ntchito poyerekeza ndi kuyerekezera zovuta zomwe zimakhalapo komanso pakakhala chizindikiro cha airspeed, zonse zowonjezera komanso zamphamvu.
- Kuthamanga : Chizindikiro cha airspeed ndi chizindikiro chosindikizidwa ndi diaphragm yomwe imakhala mkati mwake. Mlandu umene uli pafupi ndi phokosoli ndi wopanikizika, ndipo phokoso limaperekedwa ndi mphamvu zamphamvu komanso zamphamvu. Pamene mpweya ukuwonjezeka, kupanikizika kwakukulu mkati mwa chingwechi kumawonjezerekanso, kuchititsa kuti chingwecho chiwonjezere. Pogwiritsa ntchito magetsi ndi magalasi, airspeed imasonyezedwa ndi singano pointer pa nkhope ya chida.
- Altimeter: Chimake chozungulira chimakhala ngati barometer ndipo chimaperekedwe ndi mpweya wochokera ku madoko otsetsereka. M'kati mwa chophimba chogwiritsira ntchito chodindira ndi phokoso la zidutswa za aneroid, zomwe zimadziwikanso kuti zopera. Zifumbazi zimasindikizidwa ndi kupanikizika kwapakati kufika pa 29.92 "Hg, kapena kulemera kwa chilengedwe cha mlengalenga. mzere wamakilomita omwe amakawerengera chifukwa cha mpweya wosagonjetsedwa.
- VSI: Chiwongolero chowoneka chowoneka chimakhala ndi diaphragm yosindikizidwa yokhazikika yomwe imagwirizanitsidwa ndi doko lolimba. Chida choyandikana nacho chimasindikizidwanso ndipo chimaperekedwa ndi mpweya wa mpweya wokhala ndi mpweya wotsikira kumbuyo kwa mulanduwo. Izi zimapangitsa kuti phokoso lizitha kusintha pang'ono pang'onopang'ono, zomwe zikutanthauza kuti ngati ndege ikupitirizabe kukwera, vutoli silidzagwirana bwino, kuti pakhale chidziwitso kuti chidziwitso chidzayang'ane pa chida. Ndege ikangotha, zovuta zomwe zimachokera m'magetsi onsewo komanso kuthamanga kwa mkati mwa diaphragm zimafanana, ndipo kuvota kwa VSI kumabwerera ku zero kusonyeza ndege.
Zolakwitsa ndi Ntchito Yodabwitsa
Vuto lovuta kwambiri ndi pitot-static dongosolo ndikutseka kwa phokoso la pitot kapena mabwalo ozungulira, kapena onse awiri.
- Ngati phokoso la pitot lidzatsekedwa, ndipo dzenje lake lidzatsuka, airspeed idzawerenga zero.
- Ngati phokoso la pitot ndi dzenje lakutsekedwa likutsekedwa, chizindikiro cha mlengalenga chidzachita ngati mapepala a altimeter, kuwerengera mpweya wapamwamba ndi kuwonjezeka kumtunda. Izi zingakhale zoopsa ngati sizidziwika pomwepo.
- Ngati piritsi (static) ikhale yotsekedwa ndipo phokoso la pitot likhalebe logwira ntchito, chizindikiro cha mpweya sichidzagwira ntchito ndipo zizindikiro sizidzakhala zolondola. Magetsi amatha kufalikira pamalo pomwe mazembera amapezeka ndipo VSI iwonetsa zero.
Vuto lina lokhala ndi pitot-static dongosolo limaphatikizapo kutopa kwachitsulo, komwe kungapangitse kufooka kwa zigawozo. Kuonjezera apo, kusokonezeka kapena kusokoneza mwadzidzidzi kungayambitse zovuta zowonjezera.
