Abstract[English]
A boundary layer relaminarization design uses an ellipsoid dome (7) and a wingtip vortex core for a lift-generating body. Holes or slots (6), connected to a core or center of a wingtip vortex of the lift-generating body via a plenum (9) and an ellipsoid dome (7) with its outlet (8) sticking out from a surface (1) experiencing low pressure, relaminarized the boundary layer to reduce the drag. Thus, with a laminar boundary layer, the lift is increased while the drag is reduced.[French]
Une conception pour le rétablissement du caractère laminaire de la couche limite selon l'invention fait appel à un dôme ellipsoïde (7) et au cœur d'un tourbillon marginal pour un corps de génération de portance. Des trous ou des fentes (6), reliés au cœur ou centre d'un tourbillon marginal du corps de génération de portance par l'intermédiaire d'un plénum (9), et un dôme ellipsoïde (7) dont la sortie (8) fait saillie à partir d'une surface (1) subissant une basse pression, rétablissent le caractère laminaire de la couche limite de manière à réduire la traînée. Ainsi, à l'aide d'une couche limite laminaire, la portance est accrue tandis que la traînée est réduite.
