    CARENAGE     ARTICULE   pour   RODES     d'AERONEF.   



   La présente invention consiste en un carénage articulé recouvrant la roue d'un aéronef dans le but de diminuer sa résistance à. l'avancement dans l'Air et pouvant s'ouvrir ou se fermer au moyen d'une commande actionnée par le pilote. 



   Il est caractérisé par le fait que dans la position de vol ou fermé, la roue peut être entièrement enfermée dans le carénage qui, de ce fait, pré- -sente à l'écoulement de   1'air,   une surface continue, la résistance à l'avan- -oement est alors minima. 



   Dans la position d'atterrissage ou ouverte, une partie du carénage s'ouvre, démasquant la roue, ou la partie de roue qui doit prendre contact avec le sol. La continuité de la surface du carénage étant alors brisée la résistance à l'avancement de celui-ci devient impo:tante. Ce phénomène est utilisé pour permettre un angle de   plunoment   plus marqué et pour constituer un frein aérody- -namique et, dans certains cas, une augmentation de sustentation.

   Dans une première forme de l'invention (Fig. I) la partie inférieure du carénage s'ouvre en deux parties articulées autour de deux axes sensiblement horizontaux situés environ au niveau de l'axe de la roue. 



   Dans une deuxième forme de l'invention (Fig. 2), la partie inférieure du carénage s'ouvre en une pièce autour d'un axe sensiblement horizontal et placé d'un côté de la roue. 



   Dans une troisième forme de l'invention   (Fil;.   3), le carénage s'ouvre dama sa plus grande partie en deux ou plusieurs pièces autour d'axes situés près de la partie supérieure de la roue. 



   Dans une quatrième forme de l'invention (Fig.   4),   les parties inférieures du carénage pivotent autour d'axes transversaux. 



   Les formes énumérées ci-dessus sont exemplatives et non limitatives. 



    REVENDICATIONS.

    ARTICULATED FAIRING for AIRCRAFT RODES.



   The present invention consists of an articulated fairing covering the wheel of an aircraft in order to reduce its resistance to. advancement in the air and can be opened or closed by means of a control actuated by the pilot.



   It is characterized by the fact that in the flight or closed position, the wheel can be completely enclosed in the fairing which, therefore, presents to the air flow, a continuous surface, resistance to the advancement is then minimum.



   In the landing or open position, part of the fairing opens, revealing the wheel, or the part of the wheel which must make contact with the ground. The continuity of the surface of the fairing then being broken, the resistance to the advancement of the latter becomes important. This phenomenon is used to allow a more pronounced plunoment angle and to constitute an aerodynamic brake and, in certain cases, an increase in lift.

 <Desc / Clms Page number 2>

 



   In a first form of the invention (FIG. I), the lower part of the fairing opens in two parts articulated around two substantially horizontal axes located approximately at the level of the axis of the wheel.



   In a second form of the invention (Fig. 2), the lower part of the fairing opens in one piece around a substantially horizontal axis and placed on one side of the wheel.



   In a third form of the invention (Fil ;. 3), the fairing opens for the most part in two or more parts around axes located near the upper part of the wheel.



   In a fourth form of the invention (Fig. 4), the lower parts of the fairing pivot about transverse axes.



   The forms listed above are illustrative and not limiting.
