BLADES WITH GEOMETRIES INSPIRED FROM A BIOENGINEERING MODEL FOR WIND AND HYDRAULIC TURBINES

摘要

The invention relates to blades with geometries inspired from a bioengineering model for wind and hydraulic turbines, the seed of tree-of-heaven being considered as model. According to the invention, the blades, depending on number, size and orientation, may be: blades of type 1 (1), which are radially arranged, at equal distances, on a single disk (2) placed at the middle of a vertical axle (3), in the case of a wind turbine with vertical axle with only one stage (4); blades of type 2 (5) which are radially arranged, at equal distances, on two disks (2) placed at 1/3 and 2/3, respectively, of the length of a vertical axle (3), in the case of a wind turbine with vertical axle with two stages (6); blades of type 3 (7), which are horizontally arranged at equal distances on a disk (8) located at the middle of a horizontal axle (9), in the case of a hydraulic turbine with horizontal axle (10).
