Abstract
A turbine engine includes a frame assembly including an outer cavity and an inner cavity with the outer cavity including at least one opening configured and adapted to communicate cooling air to the turbine case. A baffle within the outer cavity includes a plurality of openings for directing cooling airflow into the outer cavity for preventing impingement on a radially inner wall of the outer cavity for maintaining a desired temperature of the cooling air within the outer cavity.
Claims17
A turbine engine, comprising:
- a turbine section including a turbine case disposed about an axis;
- a frame assembly defining an outer cavity, wherein the outer cavity includes radially outer wall, a radially inner wall and at least one opening configured and adapted to communicate cooling air to the turbine case;
- and
- a baffle including an inlet to receive cooling air through the radially outer wall and a plurality of openings that direct cooling airflow outward in a plurality of directions transverse to the radially inner wall within the outer cavity to prevent impingement on the inner wall.

A frame assembly for a turbine engine, the frame assembly comprising:
- a plurality of vane struts extending radially outward relative to an axis;
- an outer cavity which includes an opening for communicating cooling air to a turbine section of the turbine engine;
- and
- a baffle within the outer cavity including and inlet to receive cooling air, the baffle including a plurality of openings disposed circumferentially about the baffle that direct cooling airflow outward in a plurality of directions transverse to the radially inner wall within the outer cavity for preventing impingement on a radially inner wall of the outer cavity for maintaining a desired temperature of the cooling air within the outer cavity.
