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