The invention relates to a grid-type thrust reverser comprising: a fixed structure (1) on which a rear frame (3) bearing said grids (5) is mounted; a mobile structure (7) comprising an outer wall (9), an inner wall (11) at least partially formed by at least one acoustic panel (13), and at least one partition (15) connecting the outer wall (9) to the acoustic panel (13); and actuators (16) placed between the fixed structure (1) and the mobile structure (7), extending through openings (17, 19) formed in the rear frame (3) and the partition (15). Said thrust reverser is characterised in that the rear frame (3) and the acoustic panel (13) are sufficiently radially close to each other to interfere mutually and in a controlled manner when said mobile structure (7) is in a direct jet position.
Cet inverseur de poussée à grilles comprend : une structure fixe (1) sur laquelle est monté un cadre arrière (3) supportant lesdites grilles (5); une structure mobile (7) comprenant une paroi externe (9), une paroi interne (11) formée au moins en partie par au moins un panneau acoustique (13), et au moins une cloison (15) reliant ladite paroi externe (9) audit panneau acoustique (13); et des actionneurs (16) interposés entre ladite structure fixe (1) et ladite structure mobile (7), s'étendant à travers des orifices (17, 19) formés dans ledit cadre arrière (3) et ladite cloison (15). Cet inverseur de poussée est remarquable en ce que ledit cadre arrière (3) et ledit panneau acoustique (13) sont suffisamment proches radialement l'un de l'autre pour interférer mutuellement et de manière maîtrisée lorsque ladite structure mobile (7) est en position jet direct.
