The invention relates to a blade for a turbomachine a shroud for such a blade, and a turbomachine having at least one such blade. The blade comprises a shroud which is positioned on the blade tip side of the blade and is stiffened in the region of its surface by means of a stiffening structure having at least one longitudinal stiffening element such as a rib. The height of the longitudinal stiffening element varies in the circumferential direction.

Blade, shroud and turbomachine

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.
