Abstract
An air channeling assembly includes an outer casing having a series of spaced apart air ports spaced radially outwardly from an inner casing to define a plenum therebetween. A series of baffles are disposed in the plenum and spaced radially inwardly from the outer casing. Each of the baffles includes an intermediate opening joined in flow communication with a respective one of the air ports, and first and second ends extending circumferentially oppositely away from the intermediate opening. The baffle provides a flow shield between the inner and outer casing around each of the air ports and channels air through the intermediate opening and respective air ports.

An air channeling assemblying for a gas turbine engine comprising:
- an annular outer casing having a plurality of circumferentially spaced apart air ports;
- an annular inner casing disposed coaxially with said outer casing and spaced radially inwardly therefrom to define a plenum;
- and
- a plurality of circumferentially extending, arcuate baffles, each baffle being spaced radially inwardly from said outer casing inside said plenum, and having an intermediate opening joined in flow communication with a respective one of said air ports, and first and second ends extending circumferentially oppositely away from said intermediate opening so that said baffle provides a flow shield between said inner casing and said outer casing around each of said air ports and channels air through said baffle intermediate opening and respective air port.
