Abstract
An airfoil includes an airfoil section that defines an aerodynamic profile that has leading and trailing ends. The airfoil section spans in a longitudinal direction between first and second end sections. The airfoil section includes an internal cavity that extends between the first and second end sections and a lateral side. The internal cavity includes a baffle seat therein. A baffle is laterally insertable into the internal cavity through the lateral side into a seated position in the baffle seat.
