Popis:	The influence of various unsteady aerodynamic models on the flutter prediction of propellers in axial flight is investigated. The aerodynamic models include: Theodorsen’s model, two different cascade models, and a detailed three-dimensionalmodel.Amodeloftheunsteadybehavioratanglesofattacknearandbeyondstallisalsoincluded. These aerodynamic models are implemented in an aeroelastic analysis of a multibladed propeller. The model is validated by comparing its results with experimental results from the literature. The validated model is then used to study the differences between the various aerodynamic models for different combinations of numbers of blades and advance ratios.
