Analysis of stabilizing fin at Mach numbers from 2 to 7 was performed, based on preassigned mode shapes with piston theory representing aerodynamic forces; eigenvalues of various dynamic systems were determined for flight cases along given trajectory and for hypothetical flight cases to establish flutter boundary; for 2-mode systems eigenvalues were determined analytically; for systems with more than 2 modes iterative procedure was developed to determine eigenvalues.
