Abstract
A seal system for an intersection between a turbine stator and a turbine rotor to seal cooling fluids. The seal system may be formed from a seal base extending from the turbine stator, an arm extending radially outward from the turbine rotor and toward the seal base but terminating short of the seal base thereby creating a gap between the seal base and the arm. The seal system may include a honeycomb shaped seal attached to the seal base and extending radially inward from the seal base toward the arm. An outer sealing surface of the seal may be nonparallel with a longitudinal axis about which the turbine rotor rotates thereby enabling the distance of the gap to be reduced with axial movement of the turbine rotor.

A seal system for an intersection between turbine components, comprising:
- a seal base extending from a first turbine component;
- an arm extending radially outward from the first turbine component and toward a second turbine component, but terminating short of the seal base thereby creating a gap between the seal base and the arm;
- a honeycomb shaped seal attached to the seal base and extending radially inward from the seal base toward the arm, wherein an outer sealing surface of the seal is nonparallel with a sealing surface of the arm thereby enabling the distance of the gap to be reduced with axial movement of the second turbine component.
