A study is made of the influence of a small deviation from axial symmetry of the flow in the wake behind a body on its stability. Such deviations occur, for example, in the wake behind a circular cone at an angle of attack. The problem is solved by the small-parameter method for an inviscid incompressible fluid. It is shown that deviation from axial symmetry has a strong effect on the flow stability.
