The invention relates to a modular rotor blade for a power generating turbine that allows simple replacement of individual rotor blade sections in case of damage to or malfunction of a section. The modular rotor blade comprises at least two rotor blade sections (10, 11), wherein each rotor blade section (10, 11) comprises at least one connecting part (14, 16) having at least one conical opening (41, 42), the connecting parts (14, 16) of adjacent rotor blade sections (10, 11) rest against each other such that the conical openings (41, 42) of the connecting parts (14, 16) are aligned with each other and form a continuous conical connecting opening, receiving means (18) for receiving tensioning means (28) are arranged at the smaller diameter end of the conical connecting opening, a conical bolt (30) corresponding to the continuous conical connecting opening is arranged therein, and at least one tensioning means (28) passing through the conical bolt (30) and tensioning the conical bolt (30) against the receiving means (18).
L'invention concerne une pale de rotor modulaire destinée à une turbine génératrice de courant qui permet un simple remplacement des sections de pales de rotor individuelles en cas de détérioration ou de dysfonctionnement d'une des sections. La pale de rotor modulaire comprend au moins deux sections de pales de rotor (10, 11), chaque section (10, 11) comprenant au moins une partie de connexion (14, 16) dotée d'au moins une ouverture conique (41, 42), les parties de connexion (14, 16) des sections de pales de rotor adjacentes (10, 11) reposent l'une contre l'autre de manière que les ouvertures coniques (41, 42) des parties de connexion (14, 16) soient alignées entre elles et forment une ouverture de connexion conique continue, des moyens de réception (18) destinés à recevoir des moyens de tension (28) arrangés au niveau de l'extrémité à plus petit diamètre de l'ouverture de connexion conique, un boulon conique (30) correspondant à l'ouverture de connexion conique continue y est logé, et au moins un moyen de tension (28) passant à travers le boulon conique (30) et entraînant la tension dudit boulon (30) contre les moyens de réception (18).
