For a Magnus cylinder, it is the same, and the authors did not believe it necessary to “explain why it also should apply to rotating cylinders”.

@PierreB

Here it is the average elevation angle in relation to the entire crosswind eight-figure path which counts to determine the cosine, then the cosine squared if we only count the force of the wind, and finally the cosine cubed if we count the power of the wind.

I’m sure it is just a lack of understanding on my part, but I can’t trust unsourced claims to clear things up.

I haven’t read it yet, but in addition to the Argatov paper, this also seems like it could be relevant: Unified momentum model for rotor aerodynamics across operating regimes
