Abstract
Outflow valve assemblies for an aircraft, aircraft including an outflow valve assembly, and methods for installing an outflow valve assembly on an aircraft, are provided. In one example, an outflow valve assembly includes a louver that is movably disposed to at least partially cover an opening formed through a fuselage on an aircraft. A motor is coupled to the louver and is configured to move the louver between a closed position to obstruct fluid communication through the opening and an open position to allow fluid communication through the opening between inside and outside of the aircraft. A sound absorptive panel is disposed adjacent to the opening to attenuate noise that is generated when the louver is in the open position.
