Title
(EN) AERODYNAMIC PROFILE WITH VARIABLE TWIST AND PITCH
(FR) PROFIL AÉRODYNAMIQUE À TORSION ET PAS VARIABLES
Abstract
(EN)
An aerodynamic profile is described, comprising at least one portion of aerodynamic profile (1) composed of at least one first supporting profile (3a) and at least one second supporting profile (3b) adapted to support at least one layer of coating material of such portion of aerodynamic profile (1), such portion of aerodynamic profile (1) further comprising at least first actuating means (5) adapted to cooperate with at least one of such supporting profiles (3a) or (3b) to modify IΔΘ [ a value of incidence |θ| of such profile with respect to the other supporting profile around at least one rotation axis (R-R) parallel with an opening (A) of such portion of aerodynamic profile (1).
(FR)
La présente invention concerne un profil aérodynamique comprenant au moins une partie de profil aérodynamique (1) composée d'au moins un premier profil de support (3a) et d'au moins un second profil de support (3b) conçu pour supporter au moins une couche de matériau de revêtement de ladite partie de profil aérodynamique (1), ladite partie de profil aérodynamique (1) comprenant en outre au moins un premier moyen d'actionnement (5) conçu pour coopérer avec au moins un desdits profils de support (3a) ou (3b) pour modifier IΔΘ [une valeur d'incidence |θ| dudit profil par rapport à l'autre profil de support autour d'au moins un axe de rotation (R-R) parallèle à une ouverture (A) de ladite partie de profil aérodynamique (1)].
