КИНЕМАТИКА И ГИДРОДИНАМИЧЕСКОЕ СОПРОТИВЛЕНИЕ ТОРАКАЛЬНЫХ НОГ CALANUS HELGOLANDICUS (CLAUS)

Biomechanics of swimming limbs is described for Calanus helgolandicus. Five pairs of its thoracic limbs represent an integrated kinematic chain of the locomotory apparatus possessing two stable positions depending on the relative position of the thoracic segments. Hydrodynamic resistance of the C. helgolandicus swimming limb is studied by means of its enlarged model in a special hydrodynamic trough. It is revealed that resistance of the limb is dependent on its position in the flow, profile, relative position of segments and availability of hairs.
