[0001] This non-provisional patent application is a non-provisional patent application that was filed on June 18, 2018, and claims the priority of U.S. Provisional Patent Application No. 62 / 521,478, entitled "Hybrid Fluid Flow Attachment Component Integration Device". The contents of this specification are hereby incorporated by reference.

Technical Field

[0002] The present invention relates to a hybrid integration device, assembly or assembly composed of attachment parts for fluid flow, which are composed of attachment parts for fluid flow made of different materials and / or manufactured using different manufacturing methods and joined in a unique manner.

Background Art

[0003] In fluid flow systems, fittings are used to connect pipe sections, accommodate different sizes and shapes, and for other purposes such as regulating (or measuring) fluid flow. Examples of some conventional fittings for fluid flow include elbow joints, couplings, union joints, reducers, T-joints, cross joints and cap joints. Fittings for transferring oil, air, water and fuel are commonly used in many industrial applications including aircraft and other turbine engines, not only in domestic / industrial plumbing.

[0004] In conventional applications where weight is not a concern, fittings for fluid flow are often machined by forging various materials. Fittings manufactured by machining from forgings generally have a heavy weight because many of the forgings remain after machining. Although weight reduction by additional machining can justify cost increases in the case of aircraft and aerospace industries, there is a need to realize a method for manufacturing universal lightweight fittings that is more efficient than machining forgings.

[0005] Mounting parts machined from cast forged products also have other defects. For example, the internal flow paths of such mounting parts are not smooth, which can cause turbulence or interruption of the flow path. Furthermore, because such mounting parts are machined from specific forgings, there is often only one mounting method / structure (e.g., screw-in). In other words, there is a need for a mounting part assembly device that provides smooth flow paths and allows for various mounting methods / structures.

[0006] Axial-load bulge forming (ALBF) is a known technique for manufacturing complex products such as aircraft, jet engine, and other aerospace components that cannot be manufactured cost-effectively by conventional methods such as hydraulic forming, stamping, drop hammer forming, or spinning. ALBF allows for the production of complex shapes from thin-walled sheets while minimizing material wear loss. While ALBF is useful for manufacturing some mounting components such as reducing joints, T-joints, cross joints, and Y-joints, it cannot be used to manufacture other required mounting components such as threaded nipples and union joints, which require much heavier and thicker walls. In other words, there is a need to realize a method for manufacturing mounting component assembly devices that have both lightweight, thin-walled components and thick-walled components.

[0007] Common ALBF fittings such as reducing fittings, T-fittings, cross fittings, and Y-fittings are often used in combination with various other fittings. Manufacturing and stocking a large number of common ALBF fittings that are integrally molded or integrated with various different types and sizes of connectors is costly. Instead of stocking such a large and diverse range of common ALBF fittings, it has been proposed to stock a limited number of thin-walled fittings made of "standard" ALBF, which customers can then weld or swage to more "specialized" fittings / connectors. However, connecting ALBF fittings to specialized fittings is difficult for several reasons. The legs of thin-walled ALBF fittings are not uniformly thin, making welding difficult. The legs of these base fittings are often short, making it difficult to connect them to conventional swaged fittings. Also, the legs of these base fittings are rarely perfectly round, making it difficult to achieve a leak-free connection. ALBF mounting components and specialized mounting components are often formed from different materials, making welding equally difficult. Therefore, there is a need for a method that allows for easy and reliable connection of specialized mounting components to standard thin-walled mounting components manufactured using ALBF. [Overview of the Initiative]

[0008] The present invention provides a hybrid assembly of fluid-flow fittings composed of different materials and / or manufactured using different manufacturing methods. It connects individual fittings in a unique way that solves several problems of the prior art. In one preferred embodiment, the assembly consists of a standard ALBF fitting, here referred to as the base fitting, and an SMA fitting that can be used to connect another fluid-flow element, such as a pipe, to the ALBF fitting. In another preferred embodiment, the assembly consists of a standard base fitting and an SMA fitting that can be used to connect another standard fitting to the ALBF fitting. Since various ALBF / SMA fittings can be provided as kits, users can combine these fittings to form multiple hybrid assembly units tailored to specific applications.

[0009] In one preferred embodiment, the hybrid fluid flow integrator has a base fluid flow fitting connected as a whole to a custom fluid flow fitting. The base fitting is preferably formed from a thin metal sheet or tube by axial load bulge forming. The base fitting has an input port, at least one output port, and a fluid flow channel connecting these input and output ports. The custom fitting is preferably machined from a shape memory cast alloy. The custom fitting has a parent shape, a martensitic shape, an output port, an input port, the input port having an inner diameter of the martensitic shape slightly larger than the outer diameter of the output port of the base fitting, and a fluid flow channel connecting the input and output ports. The input port of the custom fitting is preferably connected to the output port of the base fitting by interference fit in the parent state.

[0010] The novel connection method can also address situations where at least one output port of the base mounting component is not perfectly circular before crimping. Furthermore, this novel connection method can address conventional connection problems such as when the base mounting component and custom mounting component are made of materials that cannot be welded, when conventional swaged mounting components cannot be used, or when the material is too thin to weld.

[0011] In another preferred embodiment, the fluid flow integration kit has a base-side fluid flow mounting component and a plurality of the above-mentioned custom-side fluid flow mounting components. The input ports of the custom-side mounting components are connected to the output ports of the base-side mounting component by a crimp fit. Since the multiple custom-side mounting components can have different output ports, the user can specialize this integration for a specific application. To prevent the custom-side mounting components from reverting to their parent shape, the kit has means for storing the custom-side mounting components below their transition temperature.

[0012] A further preferred embodiment of the manufacturing method for a custom-side fluid flow integration device includes the steps of forming a base-side fluid flow mounting component from a metal sheet, machining the custom-side fluid flow mounting component from a cast shape memory alloy, and mechanically connecting the base-side mounting component and the custom-side mounting component by attaching the input port of the custom-side mounting component to the output port of the base-side mounting component. These mounting components are configured as described above. For mechanical connection, it is preferable to deform the custom-side mounting component at a temperature below its transition temperature, attach the custom-side mounting component to the output port of the base-side mounting component, heat the custom-side mounting component, and crimp the two ports together. In one preferred method, the custom-side mounting component is deformed at a temperature considerably lower than room temperature and below its transition temperature, the custom-side mounting component is attached to the output port of the base-side mounting component, and the custom-side mounting component is heated to room temperature to perform the mechanical connection.

[0013] Because SMA mounting components are used, welding and crimping are not required. The compressive force of the SMA mounting component returning to its parent shape swages and / or coins the outer surface of the base mounting component. This compressive force returns any non-circular ports on the base mounting component to circular shape and crushes any surface defects, thus forming a leak-free seal between the custom mounting component and the base mounting component.

[0015] For illustrative purposes, several embodiments of the present invention are shown in the accompanying drawings; however, those skilled in the art will understand that the present invention is not limited to the exact configurations and means shown and described in the accompanying drawings. Throughout the specification, the same reference numerals indicate the same elements. To those skilled in the art, many possible modifications within the spirit and scope of the invention will be apparent from the following detailed description.

[0016] Unless otherwise specified, all technical and scientific terms used in the various grammatical forms have the same meaning as commonly understood by those skilled in the art to which this invention pertains. As used herein, the term “shape memory alloy (SMA)” refers to an alloy, also known as smart metal, memory metal, memory alloy, muscle wire, or smart alloy, that returns to its original ("parent") pre-deformed shape after the temperature of the deformed shape is raised above its transition temperature. As used herein, the term “transition temperature” refers to the entire temperature range over which an SMA undergoes a complete transition from the austenite phase to the martensite phase, or vice versa.

[0017] Figures 2 and 3 show a hybrid fluid flow integration device configured according to a first preferred embodiment of the present invention. The entire device is denoted by reference numeral 10. The device 10 as a whole has a base mounting component 12 and a custom mounting component 30 that are connected at overlapping fluid flow ports. In one preferred embodiment, the base mounting component 12 is T-shaped and has a central body portion 12a, an input leg portion 12b, and two output legs 12c and 12d. An input port 14 is formed at the end of the input leg portion 12b. Opposite output ports 16 and 18 are formed at the ends of the output legs 12c and 12d, respectively. These central body portion 12a and legs 12b, 12c, and 12d form a fluid flow channel that connects to the input and output ports.

[0018] In this embodiment, the base mounting component is T-shaped, but those skilled in the art will understand that the base mounting component can take various other shapes, and this does not deviate from the scope of the present invention. For example, in other embodiments, the base mounting component may be cross-shaped, Y-shaped, or in the shape of a straight, smooth bore reducer or expander.

[0019] In preferred embodiments, the base mounting component 12 is formed from a thin-walled metal sheet tube or a tube with thin walls to reduce the weight of the device 10, which is particularly important in the aerospace industry. Preferred materials for the base mounting component depend on the application, but examples include 321 and 347 grade austenitic stainless steel, various types of titanium (industrial purity 3Al-2.5V), 625 and 718 grade nickel alloys, and 3003 and 6061-0 aluminum alloys. The base mounting component 12 can be formed by known art, but in preferred embodiments shown in Figures 2 and 3, the base mounting component 12 can be formed from a metal sheet or tube by axial load bulge forming (ALBF). By using ALBF, the base mounting component can take on a wide range of complex shapes.

[0020] In one preferred embodiment, the custom-side mounting component 30 has a threaded nipple, which in whole has a cylindrical threaded body portion 30a and an input collar 30b. An output port 32 is formed at the end of the output collar 30b and is composed of the inner and outer walls of the collar. An input port 34 is formed at the opposite end of the body portion 30a. The inner and outer diameters of the input port are composed of the inner and outer walls of the input collar 30b. The ports 32 and 34 are connected by internal fluid flow channels extending within the body portion 30a and the collar 30b. As described below, the inner diameter of the output port 32 in the parent configuration is slightly smaller than the outer diameter of the input port 14 of the base-side mounting component.

[0021] In a preferred embodiment, the custom side attachment part 30 is formed from a shape memory alloy (SMA) such as Nitonol or Tinel (a titanium-nickel alloy), and the transition temperature of this alloy is about -150°F. The custom side attachment part 30 has a parent shape and a martensite shape. The parent shape is the shape of the attachment part 30 at room temperature after machining the casting material to its final dimensions and finish. In the parent shape, the microstructure of the attachment part 30 is a completely austenite structure. The martensite shape is the shape of the attachment part 30 after cooling the attachment part 30 to a temperature below the transition temperature and deforming it to expand the outer diameter of the internal fluid flow channel or the output port 32. In the martensite shape, the microstructure of the attachment part 30 is a completely martensite structure.

[0022] The custom side attachment part 30 can be formed by known techniques. In the preferred embodiment shown in FIGS. 2 and 3, the base side attachment part 30 is manufactured by machining from a casting material. This is because SMA is generally manufactured by casting. Note that the custom side attachment part 30 can also be manufactured by machining from SMA manufactured by other techniques. In other embodiments, the custom side attachment part can also be manufactured by other techniques such as casting.

[0023] In this embodiment, the custom side attachment part 30 is illustrated as a nipple, but those skilled in the art should understand that the custom side attachment part can take various other shapes without departing from the scope of the present invention. For example, in other embodiments, the custom side attachment part can be a cap joint, union joint, barb joint, valve, etc. As described below, in yet another preferred embodiment, the present invention includes a kit having various custom side attachment parts that can be connected to a standard base side attachment part to form an attachment part assembly device suitable for various purposes.

[0024] Continuing the description with reference to FIG. 3, the base-side mounting component 12 and the custom-side mounting component 30 are connected to form a hybrid fluid flow mounting component assembly 10. Generally, these mounting components are connected by an interference fit between the input port 14 of the base-side mounting component 12 and the output port 32 of the custom-side mounting component 30. As described above, the inner diameter of the output port 32 of the parent shape is slightly smaller than the outer diameter of the input port 14 of the base-side mounting component. In a preferred embodiment, first, the custom-side mounting component 30 is cooled to a temperature below its transition temperature to perform the interference fit. Next, the inner diameter of the entire custom-side mounting component 30 is expanded by known techniques, for example, by using a tapered mandrel, so that its inner diameter is slightly larger than the outer diameter of the input port 14 of the base-side mounting component 12. In another embodiment, only the inner diameter of the output port 32 is deformed and expanded. Next, the output port 32 is fitted onto the entire input port 14. Finally, the custom-side mounting component 30 is heated to room temperature, and the inner diameter of the output port 32 returns to its parent shape where it is smaller than the outer diameter of the input port 14 of the base-side mounting component. A compressive interference fit occurs at the port interface due to the negative size difference between the overlapping ports.

[0025] In the embodiments shown in FIGS. 2 and 3, the custom-side mounting component 30 is connected to the input port of the base-side mounting component. Those skilled in the art should also understand that the custom-side mounting component 30 can be connected to one of the output ports. Therefore, the characteristics, designs, etc. described below can be applied to any of the ports 14, 16, 18 or the legs 12b, 12c or 12d of the base-side mounting component.

[0026] Regarding the dimensions and material of the custom-side mounting component, it is preferable that the custom-side mounting component 30 be designed to generate sufficient compressive force on the port side, causing swaging and ensuring a leak-free seal. If the legs and / or port of the base-side mounting component were not circular during the original formation, it is preferable that the compressive force of the custom-side mounting component be high enough to deform the port back to a circular shape. Since there is a limit to the total tolerance (non-circular % + diameter tolerance) that the custom-side mounting component can handle, it is preferable to limit the diameter expansion of the custom-side mounting component in the martensite phase to approximately 8% to ensure that it returns completely to the parent shape.

[0027] The dimensions of the ports of the base-side mounting components, particularly the wall thickness, should preferably be designed to have sufficient "resistance" to the compressive force of the custom-side mounting component 30. The base-side mounting component 12 should preferably be configured to exhibit sufficient resistance to compression so that no coining occurs on its outer surface, thereby preventing small defects on the outer surface that could cause leakage from occurring. The port dimensions can be changed depending on the material of the base-side mounting component and the operating conditions of the assembly device, but they should be easily identifiable to a person skilled in the art, as described below.

[0028] In addition to providing excellent sealing properties, the interference fit and coining ensure superior resistance to axial loads. For example, in high-pressure applications such as operating pressures of 15,000 psi or less, or burst pressures of approximately 45,000 psi, the base mounting component 12 needs to be formed from a thick-walled tube made of a rigid material such as 625 Inconel. In such cases, the compressive force of the custom mounting component 12 will not cause any deformation of the base mounting component, nor will it ensure sufficient resistance to axial loads. To reinforce the deformation and coining of the base mounting component 12, the custom mounting component 30 can be lined with a harder material such as 718 Inconel, creating a contact surface that is harder than that of SMA material.

[0029] Figure 4 shows a hybrid fluid flow mounting assembly configured according to another preferred embodiment, the entire assembly denoted by reference numeral 110. Overall, the assembly 110 comprises a base mounting component 112 and several custom mounting components 130, 140, each connected at one end to output legs 112c, 112d of the base mounting component 112, and at the other end to a pipe 160 of a predetermined length. The base mounting component 112 is identical in structure and manufacture to the base mounting component 12 in the embodiments shown in Figures 2 and 3. In this embodiment, the base mounting component connects to several custom mounting components 130, 140 provided in kit form. In a preferred embodiment, the kit contains a number of custom mounting components from which the user can select and assemble the custom assembly.

[0030] Similar to the custom mounting component 30 described above, the custom mounting components 130 and 140 are each made of SMA and have input ports that connect to the port of the base mounting component 112 by a crimp fit. Continuing the explanation with reference to Figure 4, the two custom mounting components 130 and 140 each have long and short couplings, and a dry film lubricant 132 is applied to the inner diameter of at least one end of these couplings. These couplings are connected to the base mounting component 112 and a pipe 160 of a predetermined length using the same cooling / deformation / heating methods described for the custom mounting component 30 shown in Figures 2 and 3. The SMA couplings are used to swage and coin the overlapping outer surfaces of the base mounting component 112 and the pipe section 160 in the same manner as described with reference to Figures 2 and 3.

[0031] In this embodiment of the assembly device 110, the input leg portion 112b of the base-side mounting component 112 is connected to another mounting component having the same assembly device 10 as shown in Figures 2 and 3. In this embodiment, the base-side mounting components 112 and 12 are manufactured from the same material and connected using conventional techniques such as swaging or welding.

[0032] Figure 5 shows a hybrid fluid flow mounting component assembly configured according to yet another preferred embodiment, denoted by reference numeral 210. The assembly 210 as a whole comprises a base mounting component 212 and several custom mounting components 230, 240, each connected at one end to output legs 212c, 212d of the base mounting component 212, respectively, and at the other end to an additional mounting component 262, which in this embodiment preferably has beam seal adapters. The base mounting component 212 is identical in structure and manufacture to the base mounting component 12 in the embodiments shown in Figures 2 and 3. In this embodiment, the base mounting component 12 connects to several custom mounting components 230, 240, which are provided in kit form. In a preferred embodiment, the kit contains a number of custom mounting components from which the user can select and assemble a custom mounting component assembly.

[0033] Similar to the custom mounting component 30 described above, the custom mounting components 230 and 240 are each made of SMA and have input ports that connect to the ports of the base mounting component 212 and the adapter 262 by crimp fit. Continuing the explanation with reference to Figure 5, the two custom mounting components 230 and 240 each have a coupling, and a dry coating lubricant 232 is provided on the inner diameter portion of at least one end of this coupling. These couplings are connected to the base mounting component 212 and the adapter 262 using the same cooling / deformation / heating method previously described for the custom mounting component 30 shown in Figures 2 and 3. The SMA couplings are used to swage and coin the overlapping outer surfaces of the base mounting component 212 and the adapter 260 in the same manner as described with reference to Figures 2 and 3.

[0034] The assembly device, kit, and assembly (assembly) method of the present invention, as described above, exhibit superior performance and effectiveness compared to conventional methods and solve several problems of the conventional method. According to the present invention, mounting parts made of different materials and manufactured by different methods can be connected quickly, at low cost, and reliably. Since the base-side mounting part can preferably be formed from ALBF, the base-side mounting part can take on a unique and / or complex shape, and can be made from the minimum amount of material, thus reducing the overall weight compared to mounting parts obtained by machining from forgings.

[0035] Since ALBF mounting parts generally have smoother surfaces than mounting parts obtained by machining from forgings, the assembly apparatus of the present invention has a smoother flow path than conventional mounting part assembly apparatuses.

[0036] The connection method achieved by swaging and coining using SMA mounting components, which involves compression action, makes it possible to connect base-side mounting components to various mounting components having different material compositions, configurations, and / or manufacturing methods. For example, a novel mounting component assembly device can incorporate both lightweight and thin-walled components and thick-walled components.

[0037] Thin-walled mounting parts manufactured from ALBF often have non-circular shapes, surface defects, and short, / or unevenly thickened legs. These defects make it difficult or impossible to weld or connect ALBF mounting parts and swage them. The connection method of the present invention allows for easy and reliable connection of thin-walled ALBF mounting parts to other custom-made mounting parts without welding or the use of conventional swaged mounting parts.

[0038] It should be understood that the descriptions illustrating embodiments, specific examples, and data are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art should be able to make various modifications within the scope of the present invention based on the above descriptions, disclosures, and data, and all such modifications are included in the present invention.
