The invention relates to a seal arrangement for a turbomachine, especially for an aircraft engine, for sealing a radial gap between a rotor and a stator, comprising at least one seal carrier for the supporting and/or fastening of at least one seal element, wherein the seal carrier comprises a radial crosspiece extending in a radial direction of extension and an axial crosspiece, formed as a single piece with the latter and extending in an axial direction of extension, wherein the seal element is arranged at a radially inner-lying bearing surface of the axial crosspiece, and a front ring or a front ring segment, viewed in the flow direction, and/or a rear ring or a rear ring segment, each with a radially running crosspiece.

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.
