: Aeroelastic vibrations of rockets fairing, which are parabolic or conic shells, are considered. These shells are faded-in by stringers and rings. The dynamic instability of such structures in supersonic gas stream is analyzed.

Keywords: ring-stiffened conical shells, shell space mode, supersonic gas stream, vibrations of rocket deflector
