Patent

CA 2670187

An acoustic panel system is provided. The acoustic panel system includes a plurality of acoustic panel segments aligned circumferentially about an inner diameter of a fan containment case (36), each segment comprising a radially inner surface (202) defining a portion of a fluid duct, a radially outer surface (218) defining a gap (216) between the fan containment case and the acoustic panel segment, and an aft end lip (206) configured to be inserted into a mating groove in the fan containment case, at least one damping bumper (220) coupled to the radially outer surface, said bumper extending from the radially outer surface to the fan containment case, said damping bumper comprising an energy absorbing elastomeric material configured to facilitate dissipating a forced response of a vibratory stimulus.
