The investigation of behaviour of missile aeroelastic oscillation frequencies inside the dynamic stability area under variation of individual structural components mass and stiffness

The article considers the results of study of the missile oscillation frequencies sensitivity in the flow with regard to variations of the missile components mass and stiffness. The oscillation frequency is shown to increase when the mass of missile components increases and to decrease when the stiffness of missile components increases. This effect occurs inside the aeroelastic stability area.
