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
