AWE Performance
This may help with some of your calculations.
For reference the best AWE performance is Makani with a small prototype 4m² rigid wing.
wind speed = 11m/s
Power (max) = 30kW or 7.5kW/m² electrical
Power (rated) = 16kW or 4kW/m² electrical
To compare with a kitegen semi-rigid wing :
Use Miles Loyd formula to calculate maximum power
wind speed = 11m/s
wing area = 120m² projected (150m² max)
coefficient of lift = 1
effective glide ratio (including tether drag) = 7
elevation angle of kite from ground = 30°
Power (max) = 452kW or 3.0kW/m² mechanical
Assuming 80% conversion efficiency from mechanical to electrical
Power (max) = 362kW or 2.4kW/m² electrical
For YOYO cycle, only 30 -> 50% efficient (reel out, reel in)
Kitegen Stem :
Power (rated) = 109kW -> 181kW or 0.7kW/m² -> 1.2kW/m² electrical
