Vertical axis wind turbine in a falling soap film [PDF]
, 2015 Vertical axis wind turbines (VAWTs) have demonstrated a potential to significantly enhance the efficiency of energy harvesting within a wind farm. One mechanism that contributes to this enhancement is a VAWT’s inherent insensitivity to wind direction ...

Comparison of Horizontal Axis Wind Turbines and Vertical Axis Wind Turbines
IOSR Journal of Engineering, 2014 This paper gives a comparison between the horizontal axis wind turbines, or HAWTS, and the vertical axis wind turbines, or VAWTS. The two types of wind turbines are used for different purposes. Several models of both types are presented from previous research.

Spinning horizontal axis wind turbine [PDF]
, 2011 A spinning horizontal axis wind turbine is disclosed. The blades of the wind turbine are configured to allow the blades to simultaneously rotate in a vertical axis and a horizontal axis when acted upon by an external force such as a wind current. The tip

Wind Turbine Radar Cross Section
International Journal of Antennas and Propagation, 2012 The radar cross section (RCS) of a wind turbine is a figure of merit for assessing its effect on the performance of electronic systems. In this paper, the fundamental equations for estimating the wind turbine clutter signal in radar and communication ...
