Abstract
Methods of creating large specific supports during the explosive motion of a model profile, which are related with the generation of both self-similar flow with a closed dead zone of maximum possible volume and a circulatory flow, are considered. Possible mechanisms of using by birds and marine animals of the vortex energy of both the surrounding medium and a system of Π-shaped vortex bunches for facilitating their motion are discussed.
