A method for tuning a vibration response of an aircraft system (1) is disclosed, where the aircraft system (1) comprises an airframe (2) and at least one engine (10) dynamically coupled, the at least one engine (10) having an engine rotor (11) including a nose cone (20). The method comprises obtaining a range of frequencies associated with at least one resonance mode of the aircraft system (1) and adding mass within the nose cone (20) to offset at least one dominant excitation frequency of the turbofan engine (10) outside the range of frequencies associated with the at least one resonance mode of the aircraft system (1). A method of tuning dynamic coupling of an aircraft system (1) comprising an airframe (2) and an engine (10) mounted thereto is also disclosed.
