LAMINATED PASSENGER WINDOW FOR REDUCED NOISE TRANSMISSION
摘要
An aircraft window configuration utilizes a laminate build-up of the primary pane to increase damping and reduce the structural response to the turbulent boundary layer outside the aircraft. The laminate may consist of several acrylic layers or a combination of acrylic and glass layers. Noise dampening results from the introduction of a transparent visco-elastic material or a urethane. A vacuum layer may be introduced between the primary pane and a middle, or fail-safe pane. The vacuum layer decouples the panes over a broad frequency range resulting in a lower response of the inner pane that radiates noise into the passenger cabin. Such a window configuration reduces weight and improves noise performance. A damped laminate also reduces pane deflections into the air stream and improves aerodynamic performance of the aircraft.
