Outflow valve assemblies for an aircraft, an 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.
提供一种用于飞行器的流出阀组件、包括流出阀组件的飞行器、以及用于将流出阀组件安装到在飞行器上的方法。在一个示例中,流出阀组件包括百叶窗,该百叶窗可移动地设置成至少部分地覆盖穿过飞行器上的机身形成的开口。电机联接至所述百叶窗,并且被配置为使所述百叶窗在关闭位置和打开位置之间移动,所述关闭位置阻止通过所述开口的流体连通,所述打开位置允许通过所述开口在所述飞行器的内部和外部之间的流体连通。吸音板邻近所述开口设置以减弱当所述百叶窗处于所述打开位置时产生的噪声。
