EMI1.2
The present invention relates to a turbine wheel for steam or gas turbines, the blades of which consist of jet rods held at the feet and forming bodies of the same strength.
So far, such blades have been formed by rods of a prismatic basic shape, which were provided with grooves decreasing in depth towards the blade roots, which on the one hand formed blade cavities of decreasing depth and on the other hand, for the

continued through the yeast feet of the shovels and of approximately the same depth along their entire length, whereby the shovel

Blade wall thickness gradually increases downwards (Fig. 3-5).
Between the blade roots two juxtaposed radially arranged jet rods o and between the edge of the hub disk and that of the rim ring a web m enclosed by these edges is arranged to maintain the necessary spacing of these jet rods.
