Title: Airfoil seal system for gas turbine engine

Patent · Tue Jun 25 00:00:00 EDT 2013

OSTI ID:1087365

A turbine airfoil seal system of a turbine engine having a seal base with a plurality of seal strips extending therefrom for sealing gaps between rotational airfoils and adjacent stationary components. The seal strips may overlap each other and may be generally aligned with each other. The seal strips may flex during operation to further reduce the gap between the rotational airfoils and adjacent stationary components.
