Patent attributes
A vane arc segment includes an airfoil wall that defines first and second fairing platforms and a hollow airfoil section. A spar leg extends through the hollow airfoil section and has an end portion that protrudes from the hollow airfoil section. The spar leg is spaced from the airfoil wall in the hollow airfoil section such that there is a first gap. There is a support platform adjacent the second airfoil fairing and a second gap therebetween. A baffle is disposed in the first gap and is spaced apart from the airfoil wall and the spar leg so as to divide the first gap into a plenum space between the spar leg and the baffle and an impingement space between the baffle and the airfoil wall. A seal is disposed between the airfoil wall and the spar leg to seal the impingement space from the second gap.
