Aerofoil lossis airfoil yog cov duab ntu ntu uas tsim los nrog lub ntsej muag nkhaus, muab nws qhov txiaj ntsig zoo tshaj plaws ntawm kev nqa thiab rub hauv davhlau. Nqa yog cov khoom siv xws li lub zog yog perpendicular mus rau qhov kev taw qhia ntawm kev txav, thiab luag yog cov khoom sib npaug mus rau qhov kev taw qhia.
Aerofoil txhais tau li cas?
Ib airfoil (American English) lossis aerofoil (British English) yog tus ntoo khaub lig-sectional duab ntawm ib yam khoom uas nws txav los ntawm cov pa roj muaj peev xwm ua kom muaj kev nqa tseem ceeb, xws li lub tis, lub nkoj, lossis cov hniav ntawm lub kiv cua, rotor, lossis turbine. Lub cev muaj zog txav los ntawm cov kua ua rau lub zog aerodynamic.
Aerofoil yog dab tsi thiab nws hom?
Muaj qhov tseem ceeb ntawm ob hom aerofoils- symmetrical thiab non-symmetrical … Tsis yog-symmetrical aerofoil, tseem hu ua cambered aerofoil, muaj qhov sib txawv sab sauv thiab sab qis xws li chord kab tshwm sim muab tso rau saum toj nrog loj curvature.
