THRUST REVERSER COMPRISING OPTIMISED DEFLECTOR GRATINGS

摘要

The invention relates to a device comprising gratings which are used to form a reverse flow from a jet engine thrust flow. The inventive device comprises a plurality of flow diverter gratings (22) which are disposed side-by-side at the outer edge of an annular thrust flow circulation channel. Each of the gratings comprises a plurality of intersecting inner transverse blades (24A) and inner longitudinal blades (24B), two adjacent gratings being separated by a side clearance which generates a leakage flow. The device also comprises means of re-directing the aforementioned leakage flow in a direction such as to increase the effectiveness of the reverse flow, said re-direction means comprising aerodynamic appendages (36) which are mounted to at least one outer longitudinal edge of each grating.
