Summary[edit]

DescriptionSubsonic and trans-sonic airfoils.svg	English: Subsonic (1) and trans-sonic (2) airfoils at identical Mach number. A: Supersonic flow region B: Shock wave C: Area of stalled flow On the trans-sonic (or supercritical) airfoil, the deceleration of the flow on the top surface, and the strength of the shockwave with which the flow returns to a subsonic regime, are reduced. As a consequence, the stalled flow region, which occurs much further down the airfoil, is much smaller. Supercritical airfoils are used on all modern civilian airliners. Français : Profils subsonique (1) et trans-sonique (2) observés à la même vitesse. A: Zone d’écoulement supersonique B: Onde de choc C: Zone d’écoulement séparé turbulent La décélération de l’air sur l’extrados, ainsi que la puissance de l’onde de choc qui caractérise son retour à un régime subsonique, sont réduits sur le profil trans-sonique (ou "supercritique"). La zone d’écoulement séparé turbulent, qui débute plus loin sur le profil, est en conséquence réduite. Les profils trans-soniques sont utilisés sur tous les avions de ligne modernes.

SVG development InfoField	The SVG code is valid.   This diagram was created with Inkscape.   This diagram uses embedded text/digits. This diagram is a retouched picture, which means that it has been digitally altered from its original version. Modifications: Changed supercritical airfoil angle of attack, redrew supersonic zones, removed text to make i18n easier, increased size. Everything re-drawn..
