ABSTRACT:
A wind turbine having a generally vertically extending support tower upon which are mounted a front or blade section and a rear or tail section. The front section includes a generally horizontal drive shaft which is connected to a vertical drive shaft in the support tower. The rear or tail section is rotatably mounted on the support structure to permit radial oscillation of the tail section. The blade and tail section are releasably interconnected to each other such that upon manual operation of a latch, the rear or tail section can pivot independently from the front or blade section. The front section is upwardly inclined relative to the rear section whereby a universal joint is provided in the vertical drive shaft to insure that a portion of the vertical drive shaft remains perpendicular to the horizontal drive shaft connected to the front or blade section.
