Cov induced zog coefficient yog sib npaug rau square ntawm lub nqa coefficient (Cl) muab faib ua kom muaj nuj nqis: pi (3.14159) lub sij hawm tus piv piv (Ar) lub sij hawm ib tug efficiency (e). Qhov sib piv yog qhov square ntawm qhov span muab faib los ntawm tis cheeb tsam.

Yog li ntawd, yuav ua li cas nqa induced luag yuav txo tau?

Lwm txoj hauv kev txo induced luag thiab lub taub hau vortex lub zog nyob rau hauv ib lub tis tsim kuj yog raws li txo qhov kom muaj nuj nqis huab cua txav mus rau ntawm lub tis taub los ntawm aiming kom tsim tau kuj ntau ntawm cov nqa deb ntawm cov lus qhia. Wing taper ntawm lub ntsis pab qhov no zoo li tis twist.

Ib yam li ntawd, yog vim li cas ho txhawb nqa induced drag txo nrog ceev? Induced luag txo nrog (square of) ceev (rau qhov tsis tu ncua nqa ), vim yog siab dua ceev muaj huab cua ntau dua kom nrawm, yog li nws tsuas yog yuav tsum tau nrawm dua.

Tsuas yog li ntawd, yog vim li cas yog induced luag ib byproduct ntawm nqa?

Induced Drag yog ib qho inevitable tshwm sim ntawm nqa thiab yog tsim los ntawm kev hla ntawm aerofoil (xws li tis lossis tailplane) los ntawm huab cua. Huab cua ntws saum lub tis zoo li ntws mus rau sab hauv vim tias qhov txo qis tshaj qhov saum npoo yog tsawg dua qhov siab sab nraum lub tis.

Yuav ua li cas koj xam induced drag?

Cov induced zog coefficient yog sib npaug rau cov square ntawm nqa coefficient (Cl) muab faib los ntawm qhov ntau: pi (3.14159) lub sij hawm qhov piv txwv (Ar) lub sij hawm ib tug efficiency (e). Qhov sib piv yog qhov square ntawm qhov span muab faib los ntawm tis cheeb tsam.
