Investigation of the effect of the separation zone on the vibrations of a cone

A numerical experiment has been carried out to determine the decisive factor in the loss of dynamic stability by a cone with a circular conical stabilizer. It is shown that the inertia of the separation zone formed on the lateral surface of the cone can play this role.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 1, pp. 190–191, January–February, 1987.
