Title
(EN) THRUST REVERSER FORMING AN ADAPTIVE NOZZLE
(FR) INVERSEUR DE POUSSEE FORMANT UNE TUYERE ADAPTATIVE
Abstract
(EN)
The present invention relates to a thrust reverser for the nacelle of a turbojet engine comprising, on the one hand, means (11) for deflecting at least some of an air flow of the turbojet engine and, on the other hand, at least one hood (10) able to move translationally in a direction substantially parallel to a longitudinal axis of the nacelle and able to switch alternately from a closed position in which it ensures the aerodynamic continuity of the nacelle and covers the deflection means, and an open position in which it opens a passage in the nacelle and uncovers the deflection means, characterized in that the moving hood comprises at least one outer part (10a) having a downstream extension forming a nozzle and at least one internal part (10b) each of which parts is mounted such that it is translationally mobile and is connected to at least one actuating means able to allow it to be moved, each independently of the other, or together, in a substantially longitudinal direction of the nacelle. The present invention also relates to a turbojet engine nacelle comprising such a thrust reverser.
(FR)
La présente invention se rapporte à un inverseur de poussée pour nacelle de turboréacteur comprenant, d'une part, des moyens de déviation (11) d'au moins une partie d'un flux d'air du turboréacteur, et d'autre part, au moins un capot mobile (10) 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 les moyens de déviation, à une position d'ouverture dans laquelle il ouvre un passage dans la nacelle et découvre les moyens de déviation, caractérisé en ce que le capot mobile comprend au moins une partie externe (10a) présentant un prolongement aval formant tuyère et au moins une partie interne (10b) montées chacune mobile en translation et reliées à au moins un moyen d'actionnement apte à permettre leur déplacement, indépendamment l'une par rapport à l'autre ou ensemble, selon une direction sensiblement longitudinale de la nacelle. La présente invention se rapporte également à une nacelle de turboréacteur comprenant un tel inverseur de poussée.
