Abstract
A rotor blade for a turbomachine, including an airfoil () for flow deflection, a blade root () for attachment to a rotor of the turbomachine, an inner platform () between the airfoil and the blade root, and at least one pocket () defined by two axially spaced walls () extending from the side of the platform opposite the airfoil toward the blade root. A first () of these walls has an outer side (A,A) that faces away from the pocket and, in at least one cross section perpendicular to a radial longitudinal axis of the rotor blade, slopes outwardly.
