Abstract
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.
