Seal for gas turbine engine component

摘要

A gas turbine engine component includes a pressurized fluid source, (50) an airfoil (32), and a seal member (38) for selectively providing sealing at an end of the airfoil. The seal member has a stowed position for non-sealing and a deployed position for sealing. The seal member is operatively connected with the pressurized fluid source for moving the seal member between the stowed position and the deployed position.
