Abstract

A turbomachine blade ( 10 ) comprising a body ( 11 ) and an elastomer gasket ( 12 ) fastened to said body ( 11 ).

Claims (12)

1. A rotor wheel comprising:

at least one turbomachine blade, said blade comprising a body and a first elastomer gasket fastened to said body,

an inter-blade platform adjacent to said blade, the inter-blade platform is in the form of a plate that extends circumferentially, whereas, considered in a radial direction, the first gasket extends under said plate,

the inter-blade platform having a second gasket fastened to the plate, said second gasket being configured to seal a gap between the blade and the inter-blade platform, and when considered in the radial direction, the second gasket extends between the first gasket of the blade and the plate.

2. The rotor wheel according to claim 1 , wherein the first gasket is configured to seal the gap between the blade and the inter-blade platform.

3. The rotor wheel according to claim 1 , wherein the blade extends in a height direction and is in the form of, in the height direction, a root and an airfoil, the first gasket being fastened on the root and extending in a direction that is substantially perpendicular to the height direction.

4. The rotor wheel according to claim 1 , wherein the first gasket includes a linear base and a linear lip extending from the linear base, and

wherein the linear base is fastened on the blade, while the distal end of the linear lip is formed as a flyweight.

5. The rotor wheel according to claim 1 , wherein the first gasket is bonded to the body.

6. The rotor wheel according to claim 1 , wherein the body of the blade is made of composite material.

7. The rotor wheel according to claim 1 , wherein the second gasket is linear.

8. A turbomachine comprising a rotor wheel according to claim 1 .
