||13882733||Ib Svend Olesen||Ib Svend Olesen|
A system for identifying the likelihood of a wind turbine rotor blade striking a wind turbine tower comprises a device for sensing bending of a wind turbine rotor blade and a device for sensing bending of a wind turbine tower. In a preferred embodiment Long Period Grating (LPG) sensors are used to measure bending of the tower. Preferably a plurality of LPG sensors is provided along the length of the blade. In one embodiment at least one of the LPG sensors comprises two sensing elements arranged to sense in perpendicular directions. In another embodiment a plurality of LPG sensors are provided each on different sides of the wind turbine tower. A processor uses the sensed blade and tower bending to determine whether the distance between the blade and the tower will be below a predetermined minimum value. If the distance is determined to be below the predetermined minimum value a controller may be used to adjust a wind turbine variable to reduce loading on the blade and thereby reduce the likelihood of a tower strike.

An electric vehicle wind generator, containing a cylindrical chamber having wind wheels positioned therein. A shaft can be installed vertically, horizontally, or at any angle. The shaft is provided with a disk and the disk is provided with blades; the blades consist of a support beam, which is affixed to the disk, and of wings which are installed onto the beam with the help of arcs; a plurality of arcs is installed on each blade in accordance with the width and length of the blade; the arcs on the support beam can rotate, changing the angle of the wings relative to a base; the arcs are affixed by means of clamping bolts, the height of the arcs depends on the size of the turbine, and the arcs are installed beginning from the end of the blade; the base of the turbine is the component on which the turbine is installed. A small space, an air fairing, exists between the turbine and the base. The wider the blades, the larger the fairing distances between them, wherein without the fairing, an air lock is created, decreasing the efficiency of the turbine. The invention provides for an increase in the operating area of the turbine, and also for the possibility of installing the turbine on any components and assemblies.
