Abstract
A cascade of vanes for a cascade thrust reverser for an aircraft propulsion assembly nacelle includes: a first bladed stage and a second bladed stage, which are superimposed, each including rows of vanes and of spars which cross over one another so as to form a cellular structure for the passage of the air flow; and front and rear end flanges each rigidly connected to all or some of the spars of at least one of the bladed stages. The cellular structures are connected to each other, independently of the front and rear end flanges, by connectors configured to block relative displacements between the cellular structures.

A cascade for a cascade thrust reverser for an aircraft propulsion assembly nacelle, comprising:
- at least a first bladed stage and a second bladed stage which are superimposed, each comprising rows of vanes shaped to deflect an air flow, and spars which cross over with the vanes within each bladed stage so as to form together with the vanes a corresponding cellular structure for the passage of the air flow;
- a front end flange and a rear end flange arranged respectively at a front end and a rear end of the cascade and each rigidly connected to all or some of the spars of at least one of the bladed stages;
- wherein the respective cellular structures of the bladed stages are connected to each other, independently of the front and rear end flanges, by connecting means configured to block relative displacements between the cellular structures.
