Abstract
The invention concerns a moving blade system for a moving blade sequence of a continuous-flow machine, in particular a thermal gas turbine with at least two moving blade segments, of which each moving blade segment encompasses at least two moving blades that are disposed, in reference to a rotation axis of the moving blade sequence, at least primarily radially between a radially interior and a radially exterior shroud band and are coupled to the shroud bands, wherein at least the radially exterior shroud bands of the two moving blade segments encompass contact surfaces that correspond to one another, wherein radial equilibrium axes of neighboring moving blades of the at least two moving blade segments are disposed in a tilted manner by respectively axially an angle (αa, αb) relative to their respective base inclination, wherein the angles (αa, αb) in regard to the base inclination feature opposite signs. The invention concerns furthermore a continuous-flow machine as well as a method for the mounting of a moving blade sequence for a continuous-flow machine.
