Flow activated flowpath liner seal.

摘要

A stator vane liner assembly includes seal keys (90) supported in slots in the ends of vane liner segments (70) in an engine casing. Stationary vanes (120) supported in the liner segments for directing an engine airflow are urged against the keys by the engine airflow gas loads. The seal keys engage the ends of adjacent vane liners for sealing, and prevent further motion of the vanes with respect to the liner segments due to the engine airflow gas loads. Secondary seal means can be slidably captured between the seal key and vane liner segment to prevent axial and radial leakage around the seal key. The liner assembly reduces leakage of engine airflow and helps to isolate the engine casing from the thermal effects of leakage of engine airflow. <IMAGE>
