Abstract

An impingement cooling arrangement which avoids thermal cycling fatigue failures in the cooled member and cooling baffle member while retaining permanent rigid attachment of the cooling baffle member and cooled members at their periphery. The baffle includes an array of stress relieving smoothly curved in cross section furrows or grooves dispersed over the baffle surface and provides for intentional heat conduction to the furrow valley portions as a stress relieving mechanism. Heat conduction to the furrow valley portions is aided by the force of pressurized impingement cooling air at the baffle surface.
