Device to passively control the thermal dilatation of a turbomachine housing

摘要

The device has two clamps, where one clamp (24) is fixed to the upstream of the other clamp. A circumferential cavity is arranged between the two clamps, and a flow of gas prevailing at an inlet of a combustion chamber circulates in the cavity. The cavity is formed by a recess (40) arranged in the clamp (24), and the clamps enclose a maintenance clamp of a diffuser cone.
