A thrust reverser for a jet turbine engine comprises pivoting hollow doors (3) integrated in forward thrust with the external fairing of the nacelle and constituting in reverse thrust obstacles for deflecting flow to form scoops. A movable part forming a cap (23) is positioned in forward thrust between the upstream edge of the door (3) and the upstream fixed structure (6) covering the downstream structure of the forward frame (8). The upstream cap (23) is articulated on the fixed structure and connected to control means, uncovers in reverse thrust the downstream structure of the forward frame (8) which has an aerodynamic surface for directing the reversed thrust.

Un inverseur de poussée de turboréacteur comporte des portes creuses pivotantes (3), intégrées en jet direct dans le capotage extérieur de la nacelle et constituant en jet inversé des obstacles de déviation de flux en formant écopes. Une partie mobile formant casquette (23) est disposée, en jet direct, entre le bord amont de la porte (3) et la structure fixe amont (6) recouvrant la structure aval du cadre avant (8). La casquette amont (23) est articulée sur la structure fixe et associée à des moyens de commande, découvre, en inversion de poussée, la structure aval du cadre avant (8) qui présente une surface aérodynamique de guidage du flux inversé.
