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). Invenţia se referă la pale cu geometrii inspirate după un model bioingineresc, pentru turbine eoliene şi hidraulice, considerându-se ca model sămânţa de cenuşar/oţetar fals. Palele conform invenţiei, în funcţie de număr, dimensiune şi orientare, pot fi: nişte pale de tip 1 (1), care sunt dispuse radial, la distanţe egale, pe un singur disc (2) situat la mijlocul unui ax vertical (3), în cazul unei turbine eoliene cu ax vertical cu un singur etaj (4); nişte pale de tip 2 (5), care sunt dispuse radial, la distanţe egale, pe două discuri (2) situate la 1/3 şi, respectiv, 2/3 din lungimea unui ax vertical (3), în cazul unei turbine eoliene cu ax vertical cu două etaje (6); nişte pale de tip 3 (7), care sunt dispuse orizontal, la distanţe egale pe un disc (8) situat la mijlocul unui ax (9) orizontal, în cazul unei turbine hidraulice cu ax orizontal (10).
