On the Method of the Wing Hydrodynamic Characteristics ‎Calculation at Non-Stationary Movement ‎

Romanenko E.V., Pushkov S.G.

Approximate expressions of hydrodynamic forces were used to develop a mathematical model of the flat ‎rigid wing with different shape and aspect ratio varying pitch-axes location and sufficiently large heaving and ‎pitching amplitudes. A peculiarity of this model is the usage of the first–order aerodynamic derivatives ‎coefficients and kinematic parameters. Formulas for the calculation of the thrust and efficiency were derived. ‎The results of calculations are in good agreement with numerical solutions.
