Abstract
A turbine blade of fiber-reinforced plastic material is provided. The turbine blade includes a blade root as a connecting element that is connectable to a turbine shaft. The turbine shaft has a groove for accommodating the blade root in the installed state of the turbine blade on the turbine shaft. The blade root has a shape of fit finely matched to the shape of the groove of the turbine shaft as a result of a heating effect produced by a heating arrangement and acting on the blade root during installation on the turbine shaft and as a result of auto-adaptation of the shape thereof to the shape of the groove of the turbine shaft.
