The article presents a developed hydrodynamic model of deformable caudal fin in steady
motion. We obtained dependencies of thrust coefficient and hydrodynamic coefficient of
efficiency on vibration frequency and position of the axis of angular oscillations. We have
studied the influence of deformation of the ends of caudal fin model on its hydrodynamic
properties. Analysis results are offered.
Keywords: bearing surface, free vortex surface, deformable thin wing, steady motion,
caudal fin model, thrust coefficient, hydrodynamic coefficient of efficiency.
