Calibrated airspeed (CAS) yog qhia airspeed kho rau qhov ntsuas thiab qhov yuam kev. Thaum ya ntawm hiav txwv theem raws li International Standard Atmosphere tej yam kev mob (15 ° C, 1013 hPa, 0% humidity) calibrated airspeed yog tib yam li sib npaug airspeed (EAS) thiab muaj tseeb airspeed (TAS).

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog qhov txawv ntawm calibrated airspeed thiab tiag airspeed?

Muaj tseeb airspeed yog sib npaug airspeed kho rau huab cua ceev, thiab kuj yog qhov ceev ntawm lub dav hlau los ntawm huab cua uas nws ya. Calibrated airspeed feem ntau yog nyob rau hauv ob peb pob ntawm qhia airspeed , thaum sib npaug airspeed txo qis me ntsis los ntawm CAS raws li dav hlau qhov siab nce lossis ntawm kev kub ceev.

Qhov thib ob, qhov sib txawv ntawm airspeed yog dab tsi? Nov yog 4 hom airspeed, thiab txhua yam txhais tau li cas rau koj ya

  • 1) Qhia Airspeed (IAS) Qhov no yooj yim zoo nkauj.
  • 2) True Airspeed (TAS) True airspeed yog qhov ceev ntawm koj lub dav hlau txheeb ze rau huab cua uas nws ya los ntawm.
  • 3) Kev kub ceev (GS)
  • 4) Calibrated Airspeed (CAS)

Qhov thib ob, qhov txawv ntawm TAS thiab IAS yog dab tsi?

IAS yog airspeed raws li ntsuas los ntawm lub dav hlau Airspeed Indicator (ASI). Nws ib txwm tsawg dua TAS . Cov huab cua yog thinner ntawm qhov siab, yog li lub zog dynamic yuav tsawg dua rau tib lub airspeed, uas txhais tau tias IAS yuav txo thaum koj nce, tsis hais tus nqi ntawm kev txav, thaum TAS yuav zoo ib yam.

Tas e6b xam li cas?

Txiav txim siab qhov tseeb Airspeed thiab ceev qhov siab

  1. Siv lub qhov rais sab hauv ntawm sab xis, nrhiav OAT ntawm -15 ° C thiab tig lub. disk yog li qhov siab siab ntawm 5,000 ft. (
  2. Nyob rau hauv lub qhov rais sau npe "DENSITY ALTITUDE," nyeem qhov ceev qhov siab ntawm.
  3. Nrhiav IAS ntawm 130 kt., lossis "13," nyob rau sab hauv.
