Initial testing using deflectors to guide the oncoming airflow upward showed that the cross axis wind turbine produced significant improvements in power output and rotational speed performance compared to a conventional straight-bladed vertical axis wind turbine.
The data from the preliminary experimental study has shown that the 15° pitch angle cross axis wind turbine integrated with the 45° deflector recorded the highest power coefficient of 0.0785 at tip speed ratio of 0.93, an increment of about 175% compared to the conventional vertical axis wind turbine.
A cross axis wind turbine (CAWT) is designed for testing in a lab environment. The CAWT combines the advantages of horizontal and vertical axis wind turbines. The CAWT captures energy from horizontal and vertical components of skewed airflow. The CAWT outperformed the conventional straight-bladed vertical axis wind turbine.
Angle = difference between wind direction and runway heading (0–180°). The arrow points from the wind toward the runway. Values are in knots with two decimals. Example: Wind 050° at 12 kt on RWY 36 → Crosswind 9.19 kt from right, Headwind 7.71 kt. Free aviation crosswind calculator.
