A power generating system wherein a turbine (5) is mounted on top of a tower (4) or tethered underwater. The turbine (5) includes a rotor (6) having a main blade (7) connected to a rotor hub (9) and an extender section (2). An adjusting device positions the extender blade between a retracted position within the main blade and to an extended position to expose more or less of the rotor to the fluid flow. An extendible rotor blade structure provides support for an airfoil shell by extending a structural beam of a base blade portion (8) of said rotor blade through to a telescoping module of said blade, both when an extender blade portion (2) of said rotor blade is retracted and extended.

Système de production d'énergie dans lequel une turbine (5) est montée sur la partie supérieure d'une tour (4) ou attachée sous l'eau. La turbine (5) comprend un rotor (6) comportant une pale principale (7) reliée à un moyeu (9) de rotor et une section (2) d'extension. Un dispositif de réglage positionne la pale d'extension entre une position rétractée dans la pale principale et une position déployée pour exposer plus ou moins le rotor au flux de fluide. Une structure de pale de rotor extensible fournit un support pour coque profilée par déploiement d'un montant structurel d'une partie (8) de pale de base de ladite pale de rotor grâce à un module télescopique de ladite pale, quand une partie (2) de la pale d'extension de ladite pale de rotor est rétractée ou quand elle est déployée.
