  • Methods and systems for damping a cabin air compressor inlet
    Patent number: 10350863
    Abstract: A panel includes a structural substrate and a damping element including a viscoelastic material (VEM) layer coupleable to the structural substrate of the aircraft, and a constraining layer coupled to the VEM layer. The VEM layer is configured to dampen a vibration of the structural substrate. The constraining layer is configured to apply a shear force to the VEM layer.
    Type: Grant
    Filed: July 30, 2014
    Date of Patent: July 16, 2019
    Assignee: The Boeing Company
    Inventors: Alan E. Landmann, Mark A. Negley, Jaffar S. Iqbal, Bret A. Voss, Mark M. Gmerek, Giacomo Licciardi
  • Methods and systems for determining a structural parameter for noise and vibration control
    Patent number: 9805150
    Abstract: A computer system enables a noise level associated with a structural substrate to be reduced. The computer system includes a memory device for storing data, and a processor in communication with the memory device. The processor is programmed to define a modulus of elasticity, a thickness, and/or a distribution associated with one or more damping elements coupleable to the structural substrate, define at least one operating parameter associated with the structural substrate and the one or more damping elements, simulate a first performance of the structural substrate and/or the one or more damping elements to generate a first performance data set; and determine whether the first performance data set satisfies a predetermined threshold. The first performance data set is associated with the at least one operating parameter and the modulus of elasticity, the thickness, and/or the distribution associated with the one or more damping elements.
