Abstract
An exhaust liner assembly including an interface between moveable parts includes a seal liner having a plurality of slots. The size of each slot varies with the circumferential position of the liner assembly to provide a stable cavity pressure within the interface to create a stable barrier about the entire circumference of the exhaust liner assembly.
Claims14
A seal land comprising:
- a plurality of inlets that supply an airflow through the seal land, wherein the plurality of inlets define a varying flow area dependent on a circumferential position to provide circumferentially varying flow field that changes based on a circumferential location;
- and
- an injection guide in communication through a flow path with the plurality of inlets, the injection guide defining an outlet for airflow exiting the seal land.
Dependencies are inferred from the claim text.
