Abstract

An apparatus and method of preventing ground resonance of an aircraft, in which ground resonance may be prevented by detecting vibrations caused by rotation of a rotor (4, 4y, 4b) in the aircraft and adjusting stiffness and damping performance of a landing gear (5, 51, 52), are provided. The apparatus for preventing ground resonance of an aircraft includes a at least one sensor (10) for monitoring rolling of a fuselage of the aircraft according to rotation of a rotor; a vibration sensing unit (20, 21, 22) installed on the fuselage (2) and detecting vibrations of the fuselage; a damper installed on the fuselage, constituting landing gear, and varying a natural frequency of the fuselage; and a control unit (40) controlling stiffness of the damper based on a phase difference between vibration signals and the rolling of the fuselage.
