CHARACTERISTIC RAISING VERTICAL AXIS wind-energetic TURBINE EFFICIENCY WORK

T.A. Parkhomenko

In paper was the definition of quality geometry relationships of vertical axis wind-energetic turbines blade system during disigning. The testing different blade variations was made on the basis of experimental model, an optimal angles of their placing was defined and also necessery proportinals for designing of windwheel was made up. Was mention that a cardinal value at planning of VEU has a correct choice of the blade system geometry, and self-starting of VAWT practically imposible when we use chord less than 10 % winddheel diameter value.

Key words: vertical axis wind-energetic turbines, blade, chord, aerofoil, self-starting, permanent magnets
