    • A set of blades for a turbine which includes a group of blades disposed between an upper plate (12) and a lower plate (11), the group of blades defining a group of passages (3). The set of blades includes ducts (13,23) in the upper plate (12) and/or in the lower plate (11), said ducts leading, from one end situated at a point in the neighborhood of the concave surfaces of the blades, at the constriction (10) of the passage, to its other end located at a point downstream from the set of blades. A reduction in the high pressure on the concave surfaces in only two zones, one vertically above the lower plate (12) and the other vertically below the upper plate (11), reduces secondary losses, while the distribution of the pressure remains optimum in the part of the passages where the flow is non-turbulent.

    • A set of blades for a turbine which includes a group of blades disposed between an upper plate (12) and a lower plate (11) which delimit a group of passages (3). Said set of blades includes ducts (13,14) provided in the upper plate (12) and/or in the lower plate (11), each duct opening at one end in the neighborhood of the convex surface of a blade and level with the constriction (6) of the passage and at the other end at a point situated upstream from said set of blades. Reduction of the low pressure on the convex surfaces only adjacent the upper plate (12) and the lower plate (11), reducing secondary losses, while pressure distribution remains optimum in the zone of good flow of the passage.

    • A turbine stage which has a stationary blade set (204) followed by a moving blade set (205) which have blades (206, 207) mounted between a floor plate (201, 211) and a ceiling plate (202, 212).The surfaces of the ceiling plate (202, 212) and/or of the floor plate (201, 211) have as their meridian lines sinusoids with the maximum for the ceiling plate (202, 211) and the maximum or the minimum for the floor plate (201, 211) located in the plane between the blade sets. The curvature of the sinusoid at the outlet end.The curvature of the sinusoid at the outlet end of the stationary blade set (204) is calculated so as to make the tangential static pressure gradient equal to the radial static pressure gradient at the ceiling plate and/or at the floor plate equal at the outlet end of the stationary blade set (204).The disturbances are confined to restricted zones and the efficiency of the stage is thereby improved.
