Gas turbine vane with improved cooling

The invention relates to a hollow gas turbine vane (1) that is cooled by an arrangement configured to sequential cooling an endwall (10) of the vane (1) and its airfoil (20) and, at the same time, the two endwalls (10,30) of the vane (1). This arrangement can reduce cooling air demand, which can hav...

More Information
Summary:The invention relates to a hollow gas turbine vane (1) that is cooled by an arrangement configured to sequential cooling an endwall (10) of the vane (1) and its airfoil (20) and, at the same time, the two endwalls (10,30) of the vane (1). This arrangement can reduce cooling air demand, which can have a positive effect on the turbines efficiency.
