An apparatus for cooling turbine blades, especially of fluid outflow machines and including at least two cavities separated by a partition extending obliquely in the median, radial plane of the blade, the cavities with their partition walls being connected by acceleration link members for thermal exchange and the outflow and driving edges including fluid discharge openings formed therein. Each blade includes a fluid discharge opening located under the platform of the blade on the outflow edge side, through which most of the cooling air is discharged in the area of selected counter-pressure.
