摘要

The device (1) has upper and lower plates (4, 5) for stiffening a zone (6) of an acoustic protection screen (2), where the screen is made of semi-rigid foam material. The plates are coupled together by an attaching unit (7) such that the zone is sandwiched between the plates. Fixing units (8) have rods (10) equipped with end harpoons (11) that cooperate by fitting with openings (9) of an engine (3), where the rods are obtained from the upper plate. The attaching unit has a radial projection (12) arranged on the rods and traversing the screen and the lower plate.
