Patent Application
20220314906
Many systems are provided aboard vehicles, such as aircraft, that consist of moving mobile parts. Wing elements, (for example, an aileron, a flap, an air brake, etc.), elements of the thrust reversers, elements of a propeller pitch driving mechanism, (for example, on an helicopter or a turboprop engine), etc., are just a few of such mobile parts.
Mobile parts are associated with other aircraft systems. For example, most aircraft are equipped with landing gear that enables the aircraft to travel on the ground during takeoff, landing, and taxiing phases. This landing gear comprises several wheels which may be arranged according to configurations varying from one aircraft to the other. These wheels can be braked via movement of a plunger that slides relative to brake friction members. Further, some landing gear may be retracted inside the wings or the fuselage of the aircraft to decrease air drag on the aircraft during flight phases. In these systems, a landing gear strut, for example, is movable between an extended position and a retracted position.
Actuators are commonly used to affect movement of these mobile parts.
Generally, an actuator is a mechanical device for moving or controlling components of a mechanism or system. Actuators receive energy and convert the energy into the mechanical motion of an actuator member. For example, the actuator member may be able to move between an extended position and a retracted position. The energy may be transmitted to the actuator member through the use of pressurized liquids (i.e. hydraulics) or pressurized gases (i.e., pneumatics) so that the actuator member moves in response to the pressure changes in the liquid/gas. Alternatively, or additionally, the energy may be transmitted to the actuator member electrically or through other known means of transmitting energy. The energy transmission and the resulting movement of the mechanisms of the actuator, (e.g., the movement of the actuator member), may be controlled remotely or locally, and may be manually or automatically operated.
On modern aircraft, electromechanical actuators are being used to implement such mobile parts. In fact, the advantages of using electromechanical actuators are numerous: simple electric distribution and driving, flexibility, simplified maintenance operations, etc. Generally, an electromechanical actuator comprises a mobile actuating member which moves the mobile part, an electric motor intended to drive the mobile actuating member, and thus the mobile part, and one or more sensor(s) for sensing various parameters of the electromechanical actuator.
These actuators, whether hydraulic/pneumatic, electromechanical, or otherwise, require lines for energy transmission and signal transmission, (e.g., control signal transmission, feedback signal transmission, etc.). These lines are typically arranged in what is called a harness. Current harnesses in aircraft are externally mounted, via brackets, to a structure component a spaced distance from another structure component. This current design on aircraft adds weight, increases costs, and is vulnerable to damage from bird strikes, etc.

Turning now to
As shown in
The structural component 20, or parts thereof, can have any shape, cross-section or configuration, which will depend on its intended application. For example, the structural component can include any number of passageways 26 (e.g., 1-N). Each passageway can have any cross-sectional shape and can extend the entirety of the structural component 20 or sections thereof. The shape, cross-section and/or configuration of the structural component 20 can be constant along its length or sections thereof. In other embodiments, the shape, cross-section and/or configuration of the structural component can vary along its length or sections thereof.
In some embodiments, the structural component 20 can extend in a linear manner along its predetermined length, as shown in
In the embodiment shown in
In some embodiments, the structural component 20 can include or be integrally formed with an attachment interface 40, as shown in
The embodiment shown in
In some embodiments, the surfaces of the passageways 26 can be plated, coated, or otherwise formed with an anti-friction material, such as PTFE, to improve routing of the electrical wire 44 through the passageways 26 after fabrication of the structural component 20, and to mitigate any vibration effects of wires fretting against the inside of the structural component 20. Additionally or alternatively, the electrical wires 44 in some embodiments can be single or double shielded wires, and may include in these or other embodiments an anti-friction braided jacket. In embodiments where the structural component 20 is constructed out of a conductive material, the electrical wires can include an insulating jacket 48 or a layer of dielectric material. For some applications, the jacket 48 can have other properties, such as protection against electromagnetic interference (EMI) and/or high intensity radiated fields (HIRF).
According to aspects of the present disclosure, any structural component, or part thereof, can be fabricated by additive manufacturing (AM) techniques. Conventionally, the structural components have been heretofore fabricated by traditional metal fabrication techniques, such as CNC machining, forging techniques, casting techniques, or metal forming techniques. In one aspect of the present disclosure, an alternative fabrication technique or methodology is provided wherein the structural component is fabricated layer by layer via the process of, for example, direct metal laser sintering (DMLS), selective laser sintering (SLS), selective laser melting (SLM®), electron Beam Melting (EBM), electron beam freeform fabrication (EBMM), sometimes referred to as electron beam additive manufacturing (EBAM®), fused filament fabrication (FFF), sometimes referred to as fused deposition modeling (FDM®), or a similar form of additive manufacturing, depending, for example, on material selection, desired properties of the finished part, the part's intended application, etc. Embodiments of these components parts can be fabricated as described below. Other embodiments of the component parts can be fabricated with any conventional process, such as extrusion, forging, casting, metal forming, etc.
With the use of additive manufacturing techniques and methodologies in some embodiments, the designer of the structural component has a large degree of flexibility in the orientation, placement, and shape of the passageways/lines (e.g., transmission lines). For example, a number of small passageways can be placed side-by-side instead of a single large passageway. Additionally, the placement of the embedded transmission lines can be designed such that they avoid high stress areas of the structural component and has easily accessible inlets/outlets.
In some embodiments of the present disclosure, the structural components 20, 120, 220, or parts thereof, are fabricated out of metal, thermoplastic, etc., in an additive manufacturing technique. Additive manufacturing is a type of three-dimensional (3D) printing where material is solidified in a pattern controlled by computer-aided design (CAD) instructions, and the part being produced is built on a layer-by-layer basis. Unlike a conventional machining process, where material is removed from stock to produce a part, additive manufacturing builds the part by adding layers, where each layer is solidified by a computer-controlled source, such as a laser or an electron-beam, before the tray or bed moves incrementally to allow a new layer to be solidified adjacent the previous layer, or by adding solid stock material directly. Additive manufacturing is capable of producing parts from a wide variety of materials, including metals, polymers, and minerals.
One type of additive manufacturing, powder bed fusion (e.g., selective laser sintering (SLS), selective laser melting (SLM®), etc.), can be used to fabricate the structural components. The powder bed fusion technique uses a high power-density laser, or an electron-beam, to melt and infuse a metallic powder into a solid. A wide variety of alloys are compatible with the powder bed fusion technique. To start the process, a 3D CAD model is broken into layers, typically on the order of 10 to 100 μm thick, and each layer is converted to a two-dimensional (2D) image for processing. During the additive manufacturing of the powder bed fusion technique, a thin layer of metal powder is applied to an operating plate or bed, and the laser traces the 2D image of a layer, melting and fusing the powdered metal together into the shape of the layer dictated by the CAD data. Then, the plate lowers by the thickness of a layer and the recently printed layer is covered by another thin layer of the metal powder and the laser traces the next image of a layer, melting and fusing the powdered metal together into the shape of the new layer and to the previously printed layer.
In other embodiments, the structural components 20, 120, 220, or parts thereof, can be fabricated out of metal wire using EBM or EBAM®. Differing from the SLS process, direct deposition, such as EBM or EBAM® uses a wire feed for producing complex metal parts with a heat source, (e.g., electron-beam) to generate heat and melt a solid metal stock (e.g., wire or rod) into a part. The direct deposition process creates parts in an additive manner, directly depositing a solid metal stock. The direct deposition process is able to produce metal parts with strength approximately equivalent to forged metal parts.
In some embodiments of the present disclosure, the structural components 20, 120, 220, or parts thereof, can be fabricated out of thermoplastic, employing fused filament fabrication (FFF) techniques, such as fused deposition modeling (FDM®). Generally described, FDM® techniques employ a fused deposition modeling system or the like to build a 3D part or model from a digital representation of the 3D part in a layer-by-layer manner by extruding a flowable part material. The part material is extruded through an extrusion tip carried by an extrusion head, and is deposited as a sequence of paths, or “roads,” on a substrate in an x-y plane. The extruded part material fuses to previously deposited modeling material, and solidifies upon a drop in temperature. The position of the extrusion head relative to the substrate is then incremented along a z-axis (perpendicular to the x-y plane), and the process is then repeated to form a 3D part resembling the digital representation.
Movement of the extrusion head with respect to the substrate is performed under computer control, in accordance with build data that represents the 3D part. The build data is obtained by initially slicing the digital representation of the 3D part into multiple horizontally sliced layers. Then, for each sliced layer, the host computer generates a build path for depositing roads of modeling material to form the 3D part.
Of course, in some embodiments, a combination of two or more additive manufacturing techniques briefly described above can be employed to fabricate the structure components with one or more embedded passageways or lines or one or more externally formed passageways or lines. After fabrication, other post-machining or post-processing steps can be carried out.
As can be seen in
The digital model 202 at block 802 may be obtained in a number of ways. For example, the digital model 202 may be obtained by generating a solid model of the structural component and/or surface model of the inner surfaces of the passageways within CAD software 204 (see
In other embodiments, the digital model 202 may be obtained by scanning a previously fabricated component part, a prototype of the component part made from clay modeling, etc., and inputting the scanned data into a suitable CAD program, such as CAD software 204. For example, a component part may be scanned (e.g., measured) using a digitizing probe 208 that traverses the surfaces of the object to generate suitable 2 and 3 dimensional data indicative of the geometry thereof.
In yet other embodiments, the digital model 202 can be created in a CAD system with the use of computer 210 and CAD software 204. The design can be general to very detailed, but generally includes design details such as external shape and size of the part, internal passage size and location, cross-sectional shape along the structural component, and the like. In some embodiments, the digital model includes graphical data representative of the structural component 20, structural component 120, structural component 220, etc., or parts thereof.
Once the digital model 202 of the component part is obtained, the method 800 continues to block 804, where the digital model 202 can be viewed and optionally manipulated by the computer 210 within CAD software 204. For example, at block 204, the CAD technician or the like can interactively modify the digital model 202 via the CAD software 204 in order to alter the geometry of one or more portions of the component part, aiming for improved characteristics, modifications for a custom or new installation, etc. In some embodiments, the modified digital model 204 includes graphical data representative of the structural component 20, structural component 120, structural component 220, etc., or parts thereof.
Examples of suitable CAD software that be employed for carrying out aspects of some embodiments of the present disclosure include but are not limited to Solid Works, Pro-E, CATIA, etc. Once obtained and/or modified, the digital model 202 or modified digital model 212 (optional) can be saved, for example, to system memory, such as the data store 206, and/or associated memory, such as data store 226 from a local or remote server 230 or a cloud based storage solution.
Once the CAD design of the part is created, the structural component can then be fabricated, using any additive manufacturing process, such as fused filament fabrication (e.g., fused deposition modeling (FDM®)), stereolithography (SLA), selective laser sintering (SLS), electron beam melting, electron beam additive manufacturing (EBAM®), among others, with an additive manufacturing machine 222.
The additive manufacturing machine 222 is utilized to fabricate the component part in three dimensions on a bed, such as a fixture or fixtureless platform, from a CAD data file, such as the digital model 202 or modified digital model 204. In order for the additive manufacturing machine 222 to fabricate the component part in some embodiments, the CAD data file, such as the digital model 202 or modified digital model 204, may need to be translated into suitable machine instructions. Accordingly, at block 806 of the method 800, the digital model 202 or modified digital model 204 is processed for compatibility with the manufacturing system, including the additive manufacturing machine 222. In an embodiment of the present disclosure, a surface file (also known as a .stl file) is created from the either the digital model 202 or the modified digital model 204, depending on which is being used to fabricate the component part. The surface file conversion allows the manufacturing system to read CAD data from any one of a variety of CAD systems, such as CAD software 204 running on computer 210. In some embodiments, processing of the CAD data file (e.g., digital model 202, modified digital model, etc.) can be carried out by the computer 210, the additive manufacturing apparatus 222 or a combination of the computer 210 and the additive manufacturing apparatus 222.
It will be appreciated that the CAD data files or surface files may be stored on a computer-readable medium either associated with the CAD system, the manufacturing system or a networked or cloud based storage solution. For example, computer-readable media can be any available media that can be accessed by the computer 210 or the computer 210 and/or the additive manufacturing apparatus 222. By way of example, and not limitation, computer-readable media may comprise computer storage media and communication media. Computer storage media includes volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. In some embodiments, this surface file is then converted into cross-sectional slices or slice files, where each slice can be uniquely defined about its build strategy by varying the tool path, laser beam, bed, tray, etc., of the machine 222.
Once suitable machine instructions are created (if needed), such as the surface and/or slice files, at block 806, these machine instructions are then used by the additive manufacturing machine 222 to build the object or component part at block 810.
In one embodiment, an EBAM® apparatus is used to carry out the machine instructions. With EBAM®, an electron beam is used to melt wire onto a surface to build up a part. With this process, an electron-beam gun provides the energy source used for melting metallic feedstock, which is typically wire. In some embodiments, the desired wire material is selected from a group consisting of titanium, nickel chromium, austenitic nickel chromium (e.g., Inconel®, etc.), stainless steel, just to name a few. Using EBAM®, feedstock material is fed into a molten pool created by the electron beam. Through the use of computer controls, the molten pool is moved about on a substrate plate, adding material where it is needed to produce the object based on the build strategy of the part to be manufactured and represented in the CAD data file. This process is repeated in a layer-by-layer fashion, until the desired 3D object is produced.
In another embodiment, a FDM® apparatus is used to carry out the machine instructions. In this regard, a filament of the desired material passes through a heated liquefier. In some embodiments, the desired material is selected from a group consisting of thermoplastics. In some embodiments, the thermoplastics includes a class of thermoplastics comprising polyetherketoneketone (PEKK), such as Antero 800NA from Stratasys Direct Manufacturing. Other examples of materials that may be used in these embodiments include but are not limited to nylon, ABS, polyetherimide (e.g., Ultem®), thermoplastic polyurethane (TPU). Of course, other materials may be used.
The liquefier melts the material and extrudes a continuous bead, or road, of material through an extrusion tip carried by an extrusion head and deposits the material on a fixtureless platform. The extrusion head is computer controlled along the X and Y directions, based on the build strategy of the part to be manufactured and represented in the CAD data file. When deposition of the first layer is completed, the fixtureless platform indexes down, and the second layer is built on top of the first layer. This process continues in computer control until the part manufacturing is completed.
After the object, such as the component or component part, is built at block 808, one or more post processing steps can be optionally carried out at block 810. For example, the passageways of the structural components or other surfaces can be deburred or otherwise smoothed, as needed. In some embodiments in which the structural component is fabricated out of thermoplastic, the object may be plated or otherwise coated with a conductive or magnetic material. In one embodiment, one or more external surfaces of the component or component part, such as structural component 20, is plated or coated, for example, with nickel, zinc or copper.
In embodiments that manufacture the component or component part out of metal, nickel, zinc or copper plating or coatings may be applied in some embodiments and omitted in others. In these or other embodiments, the post processing steps can additionally or alternatively include plating or otherwise coating one or more of the passageways of the structural component 20 with an anti-friction material, such as PTFE. In some embodiments, the anti-friction coating can be subsequently applied via suitable processes onto the metal plating or coating.
Next, at block 904, a digital model 202 (see
Once obtained and/or modified (optional), the digital model 202 or modified digital model 212 (optional) can be saved, for example, to system memory, such as the data store 206, and/or associated memory, such as data store 226 from a local or remote server 230 or a cloud based storage solution.
Once the CAD design is created, the object, such as structural component 120 and/or 220, can then be fabricated with the use of any suitable additive manufacturing process, such as fused deposition modeling (FDM), stereolithography (SLA), selective laser sintering (SLS), electron beam additive manufacturing (EBAM®), among others, with an additive manufacturing machine 222.
The additive manufacturing machine 222 is utilized to fabricate in three dimensions the passageways/lines 126 and/or 226 onto the external surface of the conventional structural component from a CAD data file, such as the digital model 202 or modified digital model 212. In order for the additive manufacturing machine 222 to fabricate the component part in some embodiments, the CAD data file, such as the digital model 202 or modified digital model 212, may need to be translated into suitable machine instructions. Accordingly, at block 906 of the method 900, the digital model 202 or modified digital model 212 is processed for compatibility with the manufacturing system, including the additive manufacturing machine 222. Similar processing, for example, has been described above with reference to block 806.
Once suitable machine instructions are created (if needed), such as the surface and/or slice files, at block 906, these machine instructions are then used by one or more additive manufacturing machines 222 to build the passageways and/or electrical lines onto the exterior surface of a conventional structural component at block 908. It will be appreciated that the type of AM technique will depend on the intended structure (passageways, electrical lines, etc.,) to be fabricated. Optional post processing/machining can be carried out at block 910.

In this regard, a program element is provided, which is configured and arranged when executed on a computer for fabricating the component part, such as the structural component 20, the structural component 120, the structural component 220, or parts thereof.
