Title:
METHODS AND SYSTEMS FOR DAMPING CABIN AIR COMPRESSOR INLET
Document Type and Number:
Japanese Patent JP2016033006
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide methods of producing an aircraft noise-damping panel which is not bulky but lightweight, withstands an operating temperature range of the aircraft, and has no lack of relevant frequencies.SOLUTION: A panel includes a structural substrate 310 and a damping element 320 including a viscoelastic material (VEM) layer 330 coupleable to the structural substrate of the aircraft, and a constraining layer 340 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.SELECTED DRAWING: Figure 3
