Abstract
As a novel high altitude wind power system, this paper describes a cycloidal wind turbine mounted on a tethered balloon or parafoil. The rotor system was designed conceptually and the performance was estimated. The rotor blade span length is 10 meters and its diameter is 10 meters. When the rotor operates at 1,500 meters above ground, it produces 4.6 times more energy by the balloon tethered model. The parafoil tethered rotor power generation becomes 4.1 times at the same condition, which is a little smaller comparing with the balloon tethered model. The reason is its energy consumption at low wind speed condition to produce supplementary lifting force through mode conversion.
