초록 ▼

A cascade-type thrust reverser includes a fixed structure on which a rear frame supporting cascades of vanes is mounted, a mobile structure having an outer wall, an inner wall formed in part by an acoustic panel, a partition connecting the outer wall to the acoustic panel, and actuators interposed between the fixed structure and the mobile structure. The actuators extend through orifices formed in the rear frame and the partition. In particular, the rear frame radially interferes with the acoustic panel when the mobile structure is in a direct-jet position.

대표청구항 ▼

1. A cascade-type thrust reverser comprising: a fixed structure on which a rear cascade frame supporting cascades of vanes is mounted;a mobile structure comprising an outer wall, an inner wall formed at least in part by at least one acoustic panel, and at least one partition fixedly mounted on said outer wall and said acoustic panel; andactuators interposed between said fixed structure and said mobile structure, allowing the mobile structure to be slid in a downstream direction or in an upstream direction of the thrust reverser, said actuators extending through orifices formed in said rear cascade frame and said partition,wherein the fixed structure and the mobile structure move relative to one another, and said rear cascade frame on the fixed structure and said acoustic panel on the mobile structure contact each other when said mobile structure is in a direct-jet position, and said rear cascade frame on the fixed structure and said acoustic panel on the mobile structure do not contact each other when said mobile structure is in an indirect-jet position. 2. The thrust reverser as claimed in claim 1, wherein said rear cascade frame comprises, in a region of contacting with said acoustic panel, contact pads for contact with said acoustic panel. 3. The thrust reverser as claimed in claim 1, wherein said acoustic panel comprises, in a region of contacting with said rear cascade frame, contact plates for contact with said rear cascade frame. 4. The thrust reverser as claimed in claim 2, wherein said contact pads are positioned in such a way as to contact one another. 5. The thrust reverser as claimed in claim 2, wherein said contact pads are positioned on the downstream part of said rear cascade frame, and the upstream part of said rear cascade frame is shaped in such a way that, at least in the circumferential regions in which said contact pads are situated, its radial distance with respect to said acoustic panel is greater than the radial distance separating said contact pads from said acoustic panel. 6. The thrust reverser as claimed in claim 2, wherein said acoustic panel has recessed regions allowing said actuators to pass, and said contact pads are positioned in such a way as to contact said recessed regions. 7. The thrust reverser as claimed in claim 3, wherein said contact plates are positioned in recessed regions. 8. The thrust reverser as claimed in claim 1, wherein said rear cascade frame is made of composite. 9. The thrust reverser as claimed in claim 2, wherein said rear cascade frame is made of composite and wherein said contact pads are formed of glass laps. 10. An aircraft nacelle equipped with a cascade-type thrust reverser as claimed in claim 1. 11. The thrust reverser as claimed in claim 3, wherein said contact plates are positioned in such a way as to contact one another.
