Just before 4. Discussion:
Furthermore, with higher wind speeds and rotation rates, the lift coefficient exceeded the 0.50 threshold, slightly surpassing values observed in previous cases, which typically ranged between 0.40 and 0.45. Similarly, the drag coefficient also showed a slight increase, hovering slightly above 0.70.
There are very small lift coefficients and small drag coefficients, not suitable for a use in pumping mode. Certainly MARS has large dimensions if we include the sails, but it seems that the Magnus effect gives much higher lift coefficients for the same spin ratio of about 1 (see Omnidea for example).
Moreover, and returning to the initial use of MARS as a horizontally mounted drag-based VAWT, the given power coefficients (maximum Cp of 0.38) are unrealistic.
