Abstract
A gas turbine blade ( ) which has a rounded trailing edge ( ), is provided with a row of side by side arranged ceramic fibres ( ) along the trailing edge ( ). During operation of the turbine blade ( ), the rounded shape of trailing edge ( ) causes gasflows to break from the rounded edge before reaching the edge extremity. The presence of the fibres ( ) prevent the formation of vortices in the gasflow, and thereby improve turbine efficiency.
