格納式ロータブレード構造
Document Type and Number:
Japanese Patent JP2009544894
Kind Code:
A
Abstract:
A power generating system includes a turbine which is mounted on top of a tower or tethered under water. The turbine includes a rotor having a main blade connected to a rotor hub and an extender blade module. An adjusting device positions the extender blade between a retracted position within the main blade and an extended position to expose more or less of the rotor to the fluid flow. An extendible rotor blade structure provides support for an air foil shell by extending a structural beam of a base blade portion of the rotor blade through a telescoping module of the blade. This occurs both when an extender blade portion of the rotor blade is retracted and when it is extended.
