Abstract

Inventia se refera la energetica eoliana, si anume la motoare eoliene elicoidale. Turbina eoliana elicoidala in prima varianta contine un arbore cilindric, pe care sunt fixate palete elicoidale cu suprafata aerodinamica. Turbina este executata ingustata la un capat si poate fi de forma conica sau paraboloidala. In varianta a doua turbina eoliana elicoidala (2) si arborele (1) sunt executate ingustate la un capat, directia ingustarii lor fiind aceeasi, si pot fi de forma conica sau paraboloidala. Partile frontala si din spate ale fiecarei palete pot fi tesite sub un unghi de 40...60° fata de axa turbinei sau executate in forma de arc. Rezultatul consta in majorarea coeficientului de utilizare a energiei eoliene si functionarea mai eficienta la viteze mici ale vantului.The invention relates to wind energy, namely the helical wind motors. The helical wind turbine in the first variant contains a cylindrical shaft, on which helical blades with aerodynamic surface are fixed. The turbine is made narrow at one end and can be conical or paraboloidal. In the second variant, the wind turbine (2) and the shaft (1) are made narrowed at one end, the direction of their narrowing being the same, and can be conical or paraboloidal. The front and rear parts of each blade can be chamfered at an angle of 40 ... 60 ° to the turbine axis or made in the form of a spring. The result is an increase in the coefficient of use of wind energy and more efficient operation at low wind speeds.
