Impact of Design Parameters of a Stabilator on Critical Flutter Speed

Abstract An assessment of the impact of design parameters of a stabilator on the critical flutter speed is presented using a beam structural model of the aircraft. Aerodynamic characteristics were calculated based on the quasi-steady-state hypothesis. The design parameters considered include torsional stiffness, bending stiffness, and the position of the anti-flutter weight. Numerical results for a Yak-130-type aircraft are presented.
