Abstract

A thrust reverser device for an aircraft turbojet engine includes: a movable cowl, translating cascades connected to the movable cowl, a mast; and a front suspension to suspend the turbojet engine. The cascades translates between a direct jet position where the cascades are retracted in a fan casing, and an indirect jet position where the cascades are brought out of the fan casing. In particular, the cascades have a sliding connection with the mast by means of at least one spacer connected to the mast downstream of the front suspension.

First claim

What is claimed is:

1. A thrust reverser device for a turbojet engine of an aircraft comprising:
a movable cowl;
translating cascades connected to the movable cowl and displaceable between a direct jet position where the translating cascades are retracted in a fan casing, and an indirect jet position where the translating cascades are brought out of the fan casing;
a mast configured to connect the turbojet engine to the aircraft; and
a front suspension configured to suspend the turbojet engine from the mast,
wherein the translating cascades have a sliding connection with the mast via at least one spacer mounted to a sidewall of the mast downstream of the front suspension,
wherein said at least one spacer comprises fixed cascades.

2. The thrust reverser device according to claim 1 , wherein said at least one spacer is removably fixed on the mast.

3. The thrust reverser device according to claim 1 , wherein the at least one spacer includes a second spacer located between the mast and the translating cascades, the second spacer being fixed on a lateral frame of the translating cascades on which the translating cascades bear, and connected to a connecting member connected to the mast.

4. The thrust reverser device according to claim 3 , wherein the second spacer is located between the fixed cascades and an axis (A) of the thrust reverser device.

5. The thrust reverser device according to claim 3 , wherein the second spacer presents a bead, extending substantially rectilinear, parallel to an axis (A) of the thrust reverser device, and located on an edge of the second spacer which is the closest to the mast.

6. The thrust reverser device according to claim 5 , wherein the second spacer has a sliding connection with the connecting member via a groove of the connecting member and the bead.

7. The thrust reverser device according to claim 6 , wherein the bead presents a substantially half-moon shaped contour and the groove presents a contour with a substantially complementary shape.

8. The thrust reverser device according to claim 3 , wherein the connecting member is fixed relative to the mast to which the connecting member is integrated or mounted.

9. The thrust reverser device according to claim 3 , wherein the connecting member has a sliding connection relative to the mast.

10. The thrust reverser device according to claim 9 , wherein the connecting member has the sliding connection relative to the mast via a primary rail configured to guide in translation the movable cowl of the thrust reverser.

11. The thrust reverser device according to claim 10 , wherein the connecting member is integrated to an edge of the movable cowl of the thrust reverser.

12. A nacelle comprising the thrust reverser device according to claim 1 .
