Problems solved by technology

During operation, machinery may generate sound-causing vibrations.
Although such aircraft systems are generally safe, reliable, and efficient, these systems may be sources of noise or other types of unwanted sound, especially during aircraft take-off and landing operations, as well as while an aircraft is idling or taxiing at the airport.

Embodiment Construction

[0017]The following detailed description is merely exemplary in nature and is not intended to limit the inventive subject matter or the application and uses of the inventive subject matter. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.

[0018]The embodiments described herein are generally directed to sound attenuation, particularly for the suppression of noise generated by operating machinery, such as turbine systems. For purposes of illustration, certain embodiments provided herein will be described in the context of sound attenuation apparatus implemented on an aircraft, such as on a gas turbine engine, on an APU, or on an ECS. However, the present disclosure should not be viewed as limited to such aircraft-based implementations. Rather, it will be appreciated that the apparatus and methods described herein will find utility in any system that employs the use of operating machinery generating...

Abstract

A stacked cavity structure for arrangement on a mounting surface of a duct includes a support spine configured to be arranged on the mounting surface and extending into the duct with a longitudinal axis defining a longitudinal orientation. The stacked cavity structure includes a plurality of arms extending from the support spine and at least partially forming a plurality of overlapping cavities relative to the longitudinal orientation. Each of the plurality of arms includes at least a proximal first arm segment and a distal first arm segment.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a continuation of U.S. patent application Ser. No. 15 / 956,017 filed on Apr. 18, 2018. The relevant disclosure of the above application is incorporated herein by reference.TECHNICAL FIELD[0002]The subject matter disclosed herein relates to sound attenuation apparatus, and more particularly, to sound attenuation apparatus and methods of manufacturing the same that may be used in connection with turbine systems.BACKGROUND[0003]During operation, machinery may generate sound-causing vibrations. For example, modern aircraft may include various turbine systems such as jet engines (e.g., one or more gas-powered turbine engines), auxiliary power units (APUs), and / or environmental control systems (ECSs). Although such aircraft systems are generally safe, reliable, and efficient, these systems may be sources of noise or other types of unwanted sound, especially during aircraft take-off and landing operations, as well as while an a...
