[Appearance of the flutter on surface of the body of whale-like dolphins]

In the article a problem of the flow near of elastic surface body whalelike is considered. The opportunity appearance of the flutter on a surface body is shown. Additional capacity, necessary dolphin is designed at navigation in case of occurrence the flutter. It is shown, that this capacity makes about 26% of limiting capacity, output dolphin. Number Relcr = 4,4.10(6) transition to flutter's mode of the flow the body of the dolphin is found. It is discussed evolutionary formed the mechanism of antiflutter stabilization of the body.
