  • Turbomachine module provided with a device to improve radial clearances
    Patent number: 8052381
    Abstract: The invention relates to a turbomachine module comprising a device to improve radial clearances, comprising an outer casing (22), an inner casing (21) and at least one shock absorbing ring (5) connecting the casings, the module also comprising an annular cavity (43) on the downstream side of the ring (5), with a passage (42) formed in it through which an airflow (4) is drawn off from the primary flow (Fp). According to the invention, the device to improve radial clearances comprises a thermal inertia control device for the shock absorbing ring mounted on the shock absorbing ring (5), downstream from it, this device comprising at least one coat of thermal insulation (8), and at least partly delimiting the annular cavity (43) on the downstream side of it (43).
