摘要:
A turbomachine blade, in particular a turbine blade of a gas turbine includes a blade root with a cooling-fluid feed, a blade tip formed with a shroud element. At least one throughflow passage which extends in the blade longitudinal direction is arranged inside the airfoil. A shroud cooling passage is formed in the shroud element at least along a section of the latter, the shroud cooling passage being connected via an opening to the throughflow passage, and a cooling fluid flowing through this shroud cooling passage during operation of the turbomachine blade. At least one flow-guiding element for guiding at least some of the cooling-fluid flow flowing through the shroud cooling passage is arranged in the shroud cooling passage and/or in an inflow or outflow to or from the shroud cooling passage.
