ABSTRACT OF THE DISCLOSURE: A method for cooling heat-stressed blades of jet- engines, an apparatus for the implementation of the said method, and a design for heat-stressed blades, in which cooling air flows past the inner wall of the blade, emerging through small openings in the casing of the blade in the vicinity of the boundary-layer. The said cooling air flows tangentially into a vortex-tube comprising an orifice-plate and a choke in the vicinity thereof. The flow of cooling air, cooled down after flowing through the said orifice- plate, is introduced into the blade and, after flowing past the inner wall of the casing of the blade, passes out of the blade in the vicinity of the boundary-layer. The flow of heated air emerging through the choke is led away from the blade-area. This flow of air may be mixed with the cooling air or may be passed to the main flow of gas.
