Seal for gas turbine engine component

摘要

A gas turbine engine component includes a pressurized fluid source, an airfoil, and a seal member for selectively providing sealing at an end of the airfoil. The seal member includes a stowed position for non-sealing and a deployed position for sealing. The seal member is operatively connected with a pressurized fluid source for moving the seal member between the stowed position and the deployed position.

1. A gas turbine engine component comprising:
a fluid passage for providing a pressurized fluid; an airfoil; and a seal member for selectively providing sealing at an end of the airfoil, the seal member having a stowed position for non-sealing and a deployed position for sealing, wherein the seal member is operatively connected with the fluid passage for moving the seal member between the stowed position and the deployed position, wherein the seal member is formed from a ceramic material, a metal alloy material, or a composite material, wherein the seal member is a substantially planar plate, wherein the plate includes a thickness, a width that is greater than the thickness at all points along the plate, and a length that is greater than the width, wherein the width varies along the length.
