Abstract
An apparatus and method for attenuating noise and vibration in a propeller aircraft comprises a tuned vibration absorber adapted to be mounted to the skin of a fuselage of a propeller aircraft. The tuned vibration absorber may be tuned to the second harmonic of a blade passage frequency of a propeller of the aircraft. The tuned vibration absorber may be connectable to a separately formed mount, which can be mounted to the fuselage skin independently of the tuned vibration absorber. The apparatus may include a cover to prevent interference between the tuned vibration absorber and other components in the aircraft. The apparatus may be used in combination with other attenuation systems to attenuate noise and vibration over a broad range of frequencies.
