Patent

CA 2719155

The invention relates to a bypass turbojet engine nacelle comprising a downstream section equipped with a thrust reverser device comprising a moving cowl (6) mounted such that it can move in translation in a direction substantially parallel to a longitudinal axis of the nacelle and able to move alternately from a closed position in which it ensures the aerodynamic continuity of the nacelle and covers deflection means (70) and an open position in which it opens a passage in the nacelle and uncovers the deflection means, the said moving cowl also being extended by at least one nozzle section (7) mounted at a downstream end of the said moving cowl, characterized in that the nozzle section comprises at least one panel (10) mounted such that it can rotate about at least one pivot about an axis substantially perpendicular to a longitudinal axis of the nacelle, the said panel further being connected to a fixed fairing structure (2) of the turbojet engine by at least one link rod (11) mounted such that it can rotate about anchor points on the panel of the nozzle section and on the fixed structure, respectively.

L'invention concerne une nacelle de turboréacteur double flux comprenant une section aval, équipée d'un dispositif d'inversion de poussée comprenant un capot mobile (6) monté en translation selon une direction sensiblement parallèle à un axe longitudinal de la nacelle apte à passer alternativement d'une position de fermeture dans laquelle il assure la continuité aérodynamique de la nacelle et couvre des moyens de déviation (70), à une position d'ouverture dans laquelle il ouvre un passage dans la nacelle et découvre les moyens de déviation, ledit capot mobile étant également prolongé par au moins une section de tuyère (7) montée à une extrémité aval dudit capot mobile, caractérisée en ce que la section de tuyère comprend au moins un panneau (10) monté mobile en rotation autour d'au moins un pivot selon un axe sensiblement perpendiculaire à un axe longitudinal de la nacelle, ledit panneau étant en outre liée à une structure fixe (2) de carénage du turboréacteur par au moins une bielle (11) montée mobile en rotation autour de points d'ancrage respectivement sur le panneau de la section de tuyère et sur la structure fixe.
