Abstract
A damper assembly for a blade, the damper assembly defining a longitudinal direction, a lateral direction, and a vertical direction and including a base extending in the longitudinal direction from a first end to a second end, the base including a forward face, a rear face, and a top face, a first contact region defined on the top face between the first end and the second end, the first contact region defining a first curved surface, and a second contact region defined on the rear face between the first end and the second end, the second contact region defining a second curved surface. The first curved surface abuts the second curved surface at a common position in the longitudinal direction.

A damper assembly for a blade, the damper assembly defining a longitudinal direction, a lateral direction, and a vertical direction, the damper assembly comprising:
- a base extending in the longitudinal direction from a first end to a second end, the base including a forward face, a rear face, and a top face, wherein the top face defines a non-zero angle with the forward face and the forward face is parallel to the rear face;
- a first contact surface defined on the top face between the first end and the second end, the first contact surface defining a first curved surface, wherein the first curved surface is oriented outward relative the front face;
- and
- a second contact surface defined on the rear face between the first end and the second end, the second contact surface defining a second curved surface, wherein the second curved surface is oriented outward relative the rear face, and
- wherein the first curved surface abuts the second curved surface at a common position in the longitudinal direction.
A damper assembly for a blade, the damper assembly defining a longitudinal direction, a lateral direction, and a vertical direction, the damper assembly comprising:
- a base extending in the longitudinal direction from a first end to a second end, the base including a forward face, a rear face, and a top face, wherein the top face defines a non-zero angle with the forward face and the forward face is parallel to the rear face;
- a first contact surface defined on the top face between the first end and the second end, the first contact surface defining a first curved surface convex from the top face, wherein the first curved surface is oriented outward relative the front face;
- and
- a second contact surface defined on the rear face between the first end and the second end, the second contact surface defining a second curved surface convex from the rear face, wherein the second curved surface is oriented outward relative the rear face,
- wherein the base includes a flat region extending from the second end to the second contact surface, and
- wherein the flat region is shorter in the vertical direction than the first curved surface.
