Abstract
A dirt removal means for air cooled blades for removing dirt at the blade of a gas turbine engine. The means is a stamped out sheet metal that defines a deflector or plurality of deflectors adapted to overlie the inlets of the blade's internal cooling passages for diverting the dirt entrained air through a high velocity air stream and discharging the dirt entrained air while allowing the cleaner portion of air to turn the corner of the deflector and flow through the blades cooling passages. These means can be applied to existing blades.
