SUMMARY
: The laws of implementation of the mixed electrostatic-aerodynamic instability of three higher-order azimuthal modes (starting from the third mode) of a liquid jet are investigated analytically. In the situations considered, the behavior of the critical dependences as functions of the wavenumber is qualitatively similar and the difference is only quantitative. In all the cases, the instability of the higher-order azimuthal modes has the threshold nature with respect to both the external electrostatic field strength and the velocity of relative motion of the jet in the material medium.
