VERTICAL AXIS WIND TURBINE CAPABLE OF IMPROVING POWER GENERATION CAPACITY BY INCREASING DYNAMIC LIFT AT HIGH SPEED

摘要

PURPOSE: A vertical axis wind turbine is provided to increase rotation torque at low speed and high speed by increasing the aerodynamic characteristic of a blade at high speed and increasing dynamic lift for drive at low speed.;CONSTITUTION: A vertical axis wind turbine comprises a rotary shaft(11), a support bar(12), and multiple blades(20). The blades are installed at the rotary shaft and installed in the columnar direction at fixed intervals. The blade comprise a main body(21) having an edge portion(22) and a tail portion(23). A slot(31) is formed on the inner side of the blade corresponding to the rotary shaft in the longitudinal direction. A drag force generating chord unit is installed inside the main body of the blade. The drag force generating chord unit is lead in and draw out through the slot. The drive unit is installed inside the main body.;COPYRIGHT KIPO 2011
