Turbine damper

摘要

A damper for a turbine rotor assembly of a gas turbine engine includes a width dimension, a height dimension, and a length dimension, and includes a forward plate and an aft plate. The aft plate is larger than the forward plate along the width and height dimensions and includes an upper portion, which has a non-symmetric configuration and extends in the height dimension. The damper further includes a longitudinal structure extending in the length dimension and connecting the forward plate and the aft plate.

1. A damper for a turbine rotor assembly of a gas turbine engine, comprising:
a width dimension, a height dimension, and a length dimension; a forward plate; an aft plate being larger than the forward plate along the width and height dimension and having an upper portion extending in the height dimension, the upper portion having a non-symmetric configuration;
wherein the upper portion includes an upper point that includes an upper most top surface of the upper portion forming a straight profile that is generally perpendicular to a central axis extending in the height dimension of the aft plate through the upper portion and through a lower portion of the aft plate;wherein the upper portion, including the upper point, has a generally constant length along the length dimension;wherein the upper portion includes a first side with a first straight profile portion, and a second side with a second straight profile portion, the first and second sides being separated by the central axis of the aft plate extending in the height dimension of the aft plate, the first straight profile portion extending along a line below the upper point and in a direction that intersects the central axis at a different location than that of the second straight profile portion; and a longitudinal structure extending in the length dimension and connecting the forward plate and the aft plate.
