Abstract
A rotor blade having an integral platform with a cooled fillet is disclosed. Various construction details are developed which provide a cooling hole extending in proximity of the fillet to convectively cool the fillet. In a particular embodiment, a rotor blade having a integral platform and fillet includes a cooling hole extending between an internal cooling passage and a damper cavity. The cooling hole has a streamwise axis oriented in the direction to a line tangent to a midpoint of the fillet. The cooling hole directs a flow of cooling fluid radially inward and laterally outward, the cooling fluid flowing in proximity to the fillet to provide convective cooling.
