<p>The module has a damping ring (5) to connect an outer case (22) and an inner case (21). A radial clearance improving device has a control device for controlling thermal inertia of the inner case and the ring. The ring has a thermal insulating material housed in a cavity (81) and protecting an upstream air flow (44). The cavity is delimited by the inner case, an upstream side of the ring and an annular covering sheet (70) that connects the inner case and the ring.</p> |
