New analytical method is used to estimate hydrodynamic forces produced by dolphin's flukes. A mathematical model is proposed that describes dolphin's flukes as a flat rigid rectangular wing whose pitch axis location varies, heaving and pitching amplitudes are sufficiently large, and the phase angle shift for the combined oscillations can change arbitrarily.(More)
The inductive reactance of a flat and rigid wing performing harmonic oscillations with a sufficiently large amplitude at an arbitrary position of the axis of rotation was estimated. In the plane problem, analytical expressions for the components of inductive reactance through the coefficients of hydrodynamic derivatives for harmonic variations in the angle(More)
