Abstract: A mounting assembly for mounting a sound-deadening body to a fuselage of an aircraft and a method for attaching a sound-deadening body to a fuselage of an aircraft using the mounting assembly is disclosed herein. In a non-limiting embodiment, the mounting assembly includes, but is not limited to, a retaining member that is configured to engage the sound-deadening body. The mounting assembly further includes an isolating member that is engaged with the retaining member. The isolating member is configured for connection to the fuselage and is further configured to diminish transmission of vibration from the fuselage to and through the retaining member, and therefore to reduce the transmission of sound into the cabin.

Abstract: Aircraft, wing-to-body fairing assemblies, and air exchange systems are provided. An aircraft includes a fuselage, a wing secured to the fuselage, an outer skin panel, and an air exchange system. The outer skin panel is secured to the wing and/or the fuselage and at least partially defines a cavity. The air exchange system is secured to the outer skin panel and exchanges air between the cavity and an external environment. The air exchange system includes an air inlet, a diffuser, and a silencer. The air inlet is disposed in the outer skin panel and accommodates an air flow between the cavity and the external environment. The diffuser is attached to the air inlet and has a varying cross sectional area to change the speed of the air flow. The silencer is attached to the diffuser and communicates the air flow between the diffuser and the cavity and reduces noise.

Abstract: A method for attaching a component to an internal portion of an aircraft fuselage is disclosed herein. The method includes mounting a vibration isolator assembly to the internal portion of the aircraft fuselage. The vibration isolator assembly has a protruding engagement portion having a flange. The method further includes defining an opening in a vibration-deadening body. The method further includes positioning the vibration-deadening body over the vibration isolator such that the protruding engagement portion is received within the opening. The method further includes pressing a retaining member onto the protruding engagement portion such that the retaining member engages the flange. The retaining member will retain a portion of the vibration-deadening body below an end of the protruding engagement portion. The method still further includes attaching the component to the protruding engagement portion.
