Blades and blade dampers for gas turbine engines

1. A blade damper, comprising:

a damper body having a first leg, a second leg disposed adjacent to the first leg, a third leg, and a fourth leg disposed adjacent to the third leg, and the first leg and the second leg are parallel with a longitudinal axis of the damper body and the third leg and the fourth leg are parallel with a lateral axis that is disposed transverse to the longitudinal axis,

wherein the damper body defines a first damping surface and a second damping surface on an opposite side of the damper body from the first damping surface,

wherein the first damping surface is identical to the second damping surface for providing full functionality when rotated 180 degrees about one of its longitudinal axis and latitudinal axis and rotated about its radial axis.

2. A damper as recited in claim 1 , wherein the second damping surface is identical to the first damping surface when the damper body is rotated 180 degrees about its lateral axis and rotated about its radial axis.

3. A damper as recited in claim 1 , wherein the second damping surface is identical to the first damping surface when the damper body is rotated 180 degrees about its longitudinal axis and rotated about its radial axis.

4. A damper as recited in claim 1 , wherein the damper body has two-fold rotational symmetry about a symmetry axis of the damper body.

5. A damper as recited in claim 4 , wherein the symmetry axis is a radial axis of the damper body.

6. A damper as recited in claim 4 , wherein the symmetry axis is a longitudinal axis of the damper body.

7. A damper as recited in claim 1 , wherein the damper body has a first and a second bearing lobe which define the first damping surface.

8. A damper as recited in claim 7 , wherein the damper body has a third and a fourth bearing lobe which define the second damping surface.

9. A damper as recited in claim 7 , wherein the first and second bearing lobes define a seal receptacle extending between adjacent sides of the bearing lobes.

10. A damper as recited in claim 9 , wherein the seal receptacle is a first seal receptacle, wherein the third and fourth bearing lobes define a second seal receptacle extending between adjacent sides of bearing lobes, and wherein the second seal receptacle is disposed transverse to the first seal receptacle.

11. A blade damper, comprising:

a damper body having a first lobe, a second lobe disposed adjacent to the first lobe, a third lobe, and a fourth lobe disposed adjacent to the third lobe, the first lobe and the second lobe are parallel with a longitudinal axis of the damper body and the third lobe and the fourth lobe are parallel with a lateral axis that is disposed transverse to the longitudinal axis,

wherein the first lobe and the second lobe define a first damping surface on the damper body and the third lobe and the fourth lobe define a second damping surface on an opposite side of the damper body from the first damping surface;

wherein the first damping surface is identical to the second damping surface for providing full functionality when rotated 180 degrees about one of its longitudinal axis and latitudinal axis and rotated about its radial axis.

12. A damper as recited in claim 11 , wherein the second damping surface is identical to the first damping surface when the damper body is rotated 180 degrees about its lateral axis and rotated about its radial axis.

13. A damper as recited in claim 11 , wherein the second damping surface is identical to the first damping surface when the damper body is rotated 180 degrees about its longitudinal axis and rotated about its radial axis.

14. A damper as recited in claim 11 , wherein the damper body has two-fold rotational symmetry about a symmetry axis of the damper body.

15. A damper as recited in claim 14 , wherein the symmetry axis is a radial axis of the damper body.

16. A damper as recited in claim 14 , wherein the symmetry axis is the longitudinal axis of the damper body.

17. A damper as recited in claim 11 , wherein the damper body has a first leg and a second leg that are parallel one another and parallel the longitudinal axis.

18. A damper as recited in claim 11 , wherein the damper body has a third and a fourth leg that are parallel one another and parallel the latitude axis.

19. A damper as recited in claim 11 , wherein the first and second bearing lobes define a seal receptacle extending between adjacent sides of the bearing lobes.

20. A damper as recited in claim 19 , wherein the seal receptacle is a first seal receptacle, wherein the third and fourth bearing lobes define a second seal receptacle extending between adjacent sides of bearing lobes, and wherein the second seal receptacle is disposed transverse to the first seal receptacle.
