Abstract
An airfoil including a spar and a cover sheet that are configured for cooling. The spar includes standoffs and a leading edge wall. The standoffs are disposed along a pressure and/or suction side. A pressure-side panel and a suction-side panel are coupled to the standoffs and/or the leading edge wall. Leading ends of the pressure-side panel and the suction-side panel are disposed adjacent to one another proximate to the leading edge. The standoffs extend beyond the pressure-side leading end toward the leading edge wall. At least one of the leading ends of the pressure-side and suction-side panels defines a notch to form an outlet port at the leading edge. Standoffs may be disposed to define grooves in between in communication with the outlet port.
