Abstract
A blocker door for a thrust reverser includes: a structural frame which is configured to ensure the mechanical strength of the blocker door; an alveolar core; and an acoustically porous resistive skin which is intended to be located on the air flow side. The structural frame covers less than 50% of the surface of the resistive skin and is kept at a distance from the resistive skin. This separation between the structural frame and the resistive skin makes it possible to improve the impact behavior of the blocker door. The resistive skin and the alveolar core preferably form a one-piece subassembly into which the structural frame fits. The door may be devoid of a rear skin.
