| Abstract: | 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.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 4, pp. 155–158, July–August, 1984.I thank G.
