Turbine Engine Rotor Blade With Contoured Pocket Surface(S)

An apparatus for a turbine engine, comprising:

• a rotor blade including a base, an airfoil and a cooling circuit, the rotor blade extending along a span line from an inner end of the base to an outer tip of the airfoil;
• the base including a platform, an attachment and a contoured side surface spanwise between the platform and the attachment, the contoured side surface including a first convex section, a second convex section and a concave section when viewed in a reference plane perpendicular to the span line, and the concave section extending between the first convex section and the second convex section;
• the airfoil connected to the base and projecting spanwise out from the platform to the outer tip of the airfoil;
• and
• the cooling circuit including a first cooling channel and a second cooling channel, the first cooling channel projecting spanwise partially into the base from the inner end of the base and aligned with the first convex section in the reference plane, and the second cooling channel projecting spanwise partially into the base from the inner end of the base and aligned with the second convex section in the reference plane.

An apparatus for a turbine engine, comprising:

• a rotor blade configured to rotate about an axis and including a base and an airfoil;
• the base including a platform, an attachment, a pocket and a laterally undulating side surface, the pocket located radially between the platform and the attachment, the pocket projecting radially outward into the base and along the laterally undulating side surface to the platform, the pocket extending axially within the base and along the laterally undulating side surface between opposing axial ends of the pocket, the pocket projecting laterally into the base to the laterally undulating side surface, the laterally undulating side surface extending axially between the opposing axial ends of the pocket and continuously laterally undulates between the opposing axial ends of the pocket, and the laterally undulating side surface including a plurality of lateral undulations located at discrete locations axially along the axis between the opposing axial ends of the pocket;
• and
• the airfoil projecting radially outward from the platform to a tip of the airfoil.
