Excerpt from the book
The non-Orthodox pressurization motion behavior of a mackerel fin.
When the momentum exchange at the membrane surface of caudal fin is very high, the biological control and control surface behaves flexible, resilient elastic and can yield a non-axial flow. The pressurization deformation interaction correlated with the direction of the force acting in the sense of a conventional stress-strain regime. Conventionally deformed components behave mechanically Orthodox. In normal operation, however, technically speaking the "design range of flow component" shows a fish fin mechanically nonorthodox, indeed paradoxical deformation behavior: a direction opposite to the force acting deformation realize paradoxical pressurization Deformation interactions.
