Abstract
Due to the anomalous behaviour of the Joukowsky rotor, this model is analysed in details for small tip speed ratios. The analysis is carried analytically and by comparison to additional CFD computations and some recent experiments. It is found that the model only attains a well-defined optimum for tip speed ratios larger than 0.93, but that other inherent features of the equations by themselves will limit the power performance at smaller tip speed ratios.
