The present disclosure generally relates to fluid conduits, including fluid conduits that may be used in connection with aircraft.
This background description is set forth below for the purpose of providing context only. Therefore, any aspect of this background description, to the extent that it does not otherwise qualify as prior art, is neither expressly nor impliedly admitted as prior art against the instant disclosure.
Some fluid conduits may not be sufficiently strong, may be heavy, may be large, and/or may involve a complex assembly process.
There is a desire for solutions/options that minimize or eliminate one or more challenges or shortcomings of fluid conduits. The foregoing discussion is intended only to illustrate examples of the present field and should not be taken as a disavowal of scope.
In embodiments, a fluid conduit may include a body and a reinforcing portion integrally formed with the body. The reinforcing portion may be disposed at an inner surface of the body. The reinforcing portion may include a grid structure. The grid structure may include a plurality of beams that may provide a plurality of rectangular cells. A fluid conduit may be formed via additive manufacturing. A body and a reinforcing portion may be formed as a monolithic component.
The foregoing and other aspects, features, details, utilities, and/or advantages of embodiments of the present disclosure will be apparent from reading the following description, and from reviewing the accompanying drawings.
Reference will now be made in detail to embodiments of the present disclosure, examples of which are described herein and illustrated in the accompanying drawings. While the present disclosure will be described in conjunction with embodiments and/or examples, it will be understood that they are not intended to limit the present disclosure to these embodiments and/or examples. On the contrary, the present disclosure is intended to cover alternatives, modifications, and equivalents.
In embodiments, such as generally illustrated in
With embodiments, a reinforcing portion 30 may be disposed at or about an inner surface 22 of a body 20 and/or a reinforcing portion 30 may be disposed at or about an outer surface 24 of the body 20. A reinforcing portion 30 may include one or more of a variety of shapes, sizes, configurations, and/or materials. For example and without limitation, a reinforcing portion 30 may include a grid structure 32 that may include a plurality of beams 34 that may be interconnected to form a plurality of cells 36. The beams 34 may extend from the inner surface 22 of the body 20 in a substantially radial direction, such as radially inward. The beams 34 may be interconnected to form a plurality of cells 36 that may include one or more shapes. For example and without limitation, the cells 36 may include, without limitation, rectangular, square, and/or triangular shapes/configurations. The beams 34 may have a height or thickness 34H that may correspond to an anticipated or intended amount of bending stress. A height or thickness 34H of beams 34, which may or may not be the substantially the same for each beam 34, may be larger for fluid conduits 10, or sections of fluid conduits 10, for which increased or greater expected amounts of bending stress may occur or may be anticipated to occur. Additionally or alternatively, a height or thickness 34H of beams 34 may be lesser or smaller for fluid conduits 10 or sections of fluid conduits 10 with lesser expected amounts of bending stress. A height or thickness 30T of reinforcing portion 30 (e.g., a maximum height of beams 34) may, for example and without limitation, be at least as thick as a thickness 20T of other portions of body 20 (e.g., a fluid conduit 10 may be twice as thick at or about a reinforcing portion 30).
In embodiments, such as generally illustrated in
With embodiments, such as generally illustrated in
With embodiments, a reinforcing portion 30 may extend along an inner surface 22 of the body 20. A reinforcing portion 30 may extend partially or entirely around a perimeter or circumference 20C (e.g., an inner circumference) of the body 20. For example and without limitation, a circumferential extent 30C of a reinforcing portion 30 may be less than half of a circumference 20C of the body 20. In embodiments, a reinforcing portion 30 may extend along all or part of an axial length 20L of a body 20. An axial extent 30L of a reinforcing portion 30 may correspond to a size of an area of anticipated or expected increased stress, for example and without limitation, a shape or extent sufficient to cover a footprint and/or provide reinforcement for an external component 40.
With embodiments, a circumferential extent 30C and/or an axial extent 30L of a reinforcing portion 30 may be relatively small compared to a circumference 20C and/or an axial length 20L of a body 20, which may provide the body 20 with a lower overall weight and sufficient strength in areas of intended or expected increased stress. For example and without limitation, a circumferential extent 30C and/or an axial extent 30L of a reinforcing portion 30 may be less than 50%, less than 25%, less than 10%, and/or less than 1% of a circumference 20C of a body 20 and/or an axial length 20L of body 20, respectively. In embodiments, a circumferential extent 30C and/or an axial extent 30L of a reinforcing portion 30 may be greater than 50% of a circumference 20C of the body 20 and/or an axial length 20L of the body 20, respectively.
In embodiments, a fluid conduit 10 may be configured to act or function as a heat sink. For example and without limitation, an external component 40 may include an electrical component 46 that may be connected to an outer surface 24 of the body 20 such that the electrical component 46 may be at least partially aligned with a reinforcing portion 30 and the reinforcing portion 30 may dissipate heat generated by the electrical component 46 (see, e.g.,
In embodiments, such as generally illustrated in
With embodiments, such as generally illustrated in
With embodiments, some or all of a fluid conduit 10 may be formed as a single, unitary, and/or monolithic component (which may be referenced herein simply as “monolithic”). For example and without limitation, a body 20 and one or more reinforcing portions 30 may be formed as a monolithic component. Other designs may, for example, include separately forming a body 20 and a reinforcing portion 30, and connecting the body 20 and the reinforcing portion 30 together via fasteners, adhesive, and/or welding, among other methods.
In embodiments, a fluid conduit 10 may include one or more of a variety of materials. For example and without limitation, a body 20 and/or a reinforcing portion 30 may include a polymer, such as if the fluid conduit 10 is used in connection with aircraft cabin air flow. Additionally or alternatively, a body 20 and/or a reinforcing portion 30 may include a metal, such as if the fluid conduit 10 is used in connection with high temperature aircraft bleed air.
Various embodiments are described herein for various apparatuses, systems, and/or methods. Numerous specific details are set forth to provide a thorough understanding of the overall structure, function, manufacture, and use of the embodiments as described in the specification and illustrated in the accompanying drawings. It will be understood by those skilled in the art, however, that the embodiments may be practiced without such specific details. In other instances, well-known operations, components, and elements have not been described in detail so as not to obscure the embodiments described in the specification. Those of ordinary skill in the art will understand that the embodiments described and illustrated herein are non-limiting examples, and thus it can be appreciated that the specific structural and functional details disclosed herein may be representative and do not necessarily limit the scope of the embodiments.
Reference throughout the specification to “various embodiments,” “with embodiments,” “in embodiments,” or “an embodiment,” or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “in various embodiments,” “with embodiments,” “in embodiments,” or “an embodiment,” or the like, in places throughout the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Thus, the particular features, structures, or characteristics illustrated or described in connection with one embodiment/example may be combined, in whole or in part, with the features, structures, functions, and/or characteristics of one or more other embodiments/examples without limitation given that such combination is not illogical or non-functional. Moreover, many modifications may be made to adapt a particular situation or material to the teachings of the present disclosure without departing from the scope thereof.
It should be understood that references to a single element are not necessarily so limited and may include one or more of such element. Any directional references (e.g., plus, minus, upper, lower, upward, downward, left, right, leftward, rightward, top, bottom, above, below, vertical, horizontal, clockwise, and counterclockwise) are only used for identification purposes to aid the reader's understanding of the present disclosure, and do not create limitations, particularly as to the position, orientation, or use of embodiments.
Joinder references (e.g., attached, coupled, connected, and the like) are to be construed broadly and may include intermediate members between a connection of elements and relative movement between elements. As such, joinder references do not necessarily imply that two elements are directly connected/coupled and in fixed relation to each other. The use of “e.g.” in the specification is to be construed broadly and is used to provide non-limiting examples of embodiments of the disclosure, and the disclosure is not limited to such examples. Uses of “and” and “or” are to be construed broadly (e.g., to be treated as “and/or”). For example and without limitation, uses of “and” do not necessarily require all elements or features listed, and uses of “or” are intended to be inclusive unless such a construction would be illogical.
While processes, systems, and methods may be described herein in connection with one or more steps in a particular sequence, it should be understood that such methods may be practiced with the steps in a different order, with certain steps performed simultaneously, with additional steps, and/or with certain described steps omitted.
It is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative only and not limiting. Changes in detail or structure may be made without departing from the present disclosure.
This application claims the benefit of U.S. Provisional Patent Application Ser. No. 62/551,263, filed on Aug. 29, 2017, the disclosure of which is hereby incorporated herein by reference in its entirety.
