<p>A wind power engine comprises a conical multiple-blade turbine obligatorily surrounded by a circular deflector which creates a clear space for the evacuation of the air that has worked without being deflected by the peripheral wind (Fig. 4). The deflector also produces an acceleration of the peripheral air, thereby increasing the pressure drop and hence the useful power behind the turbine. The conical turbine may be replaced by a multiple-blade wheel if the wind is first deviated by a deflector grille so as to attack the blades obliquely, which is the principle underlying the invention, the peripheral deflector remaining obligatorily around the wheel (Fig. 2). The essential advantage of this lies in the reduction by 3/4 of the diameter of the rotating part with respect to conventional propellers. This confers a high degree of solidity on the machine, substantially reduces its manufacturing costs, and prolongs its service life.</p> |
