DescriptionAubages de redirection sur des corps 2D mal profilés d'après Hoerner.jpg |
Français : Aubages de redirection sur des corps 2D mal profilés d'après Hoerner. Les Cx avec ou sans ces aubages sont indiqués. dans le cas du montage de tels aubages de redirection sur la face avant abrupte, les efforts sur l'ensemble des aubages sont orientés vers l'avant et participent à la réduction de traînée.
English: Turning vane on poorly profiled 2D bodies, according to Hoerner. Cd's with or without these vanes are indicated. In the case of mounting such turning vanes on the steep front edge, the forces on all the vanes are oriented forward and participate in the reduction of drag. |

Il est amusant de constater que les forces sur les aubages avant tendent à entraîner le corps vers l'avant. Ces aubages ont donc deux effets : favoriser le contournement des arêtes avant par l'écoulement et entraîner le corps vers l'avant.
On peut observer une utilisation actuelle de tels aubages redirecteurs sur cette image :
Contrairement aux aubages avant, les aubages arrière sont l'objet d'une résultante aérodynamique dirigée vers l'arrière, ce qui diminue leur efficacité.
