Abstract

- Structure aérodynamique d’écoulement laminaire. - La structure aérodynamique d’écoulement laminaire comprend un corps d’écoulement (2) et un bord d’attaque (3) destiné à faire face à un écoulement circulant selon un sens d’écoulement (4), le bord d’attaque (3) étant mobile et comprenant une position rétractée dans laquelle le bord (23) de chacune de deux surfaces d’écoulement (21) du corps d’écoulement (2) est joint respectivement à un bord (33) de chacune de deux surfaces d’écoulement (31) du bord d’attaque (3) selon une ligne de jonction (41) présentant au moins une portion inclinée (43) d’un angle (α) strictement inférieur à 90° par rapport au sens d’écoulement (4). L’inclinaison d’au moins une portion (43) de la ligne de jonction (41) permet de réduire la traînée et donc de garder un écoulement laminaire sur une grande partie des surfaces extérieure de la structure aérodynamique.
