  • Plates and plate assemblies for noise attenuators and other devices and methods making the same
    Patent number: 11562726
    Abstract: Plates and plate assemblies for noise attenuators and other devices and methods of making the same are described herein. An example plate assembly includes a support frame to be coupled to a body of the noise attenuator. The support frame has a plurality of radially extending ribs. The plate assembly also includes a disc-shaped plate having a plurality of openings forming flow paths to attenuate noise. The disc-shaped plate is coupled to the support frame such that pressure-induced loads on the disc-shaped plate are distributed to the plurality of radially extending ribs of the support frame.
