composite fan blade manufacturing process

They represent the first redesign in a decade. The complicated paths taken by the blade — involving not only their linear speed and direction but rotational motion as well — are then used as the basis for determining the impact scenario in the ballistic tests. Lightweight, increased engine thrust and efficiency, low-operating-cost, and laminar airflow into the engine are som… GKN Aerospace specialises in cold and hot structural parts, and is one of the world’s leading independent suppliers of light-weight engine frame structures. Kind Code: A1 . The structural evaluation of the composite fan blade indicates that the blade would buckle at a rotor speed that is 3.5 times the design speed of 2000 rpm. endobj In a third SBIR effort, A&P Technology is currently partnered with engine manufacturers to apply the braided composite materials to specific fan case designs and their individual performance requirements. In addition, research was begun on methods used to analyze and test metal-based designs to adapt them for use with composite case designs. However, today’s composite manufacturing processes features layers in different directions to absorb the required stresses and loads. Existing GE engines that incorporate carbon composite fan blades are the company's GE90-94B, GE90-115B, and GEnx engines. During engine shut down, typically 15 seconds, cracks can propagate rapidly in the fan case from the damage caused by the impact of the broken blade. ATL and AFP: Defining the megatrends in composite aerostructures. Passive damping concepts were first validated on carbon fibre reinforced epoxy composite plates and then implemented in a 1:5 model of an open rotor blade manufactured by resin transfer moulding (RTM). Other composite manufacturing processes: infusion, RTM, hot pressing, etc. This was accomplished, in part, by integrating reliable composite material models into the explicit finite element codes currently used for blade-out analysis on metal-based cases, to adapt them for impact simulation scenarios with composite containment cases. The process of making a composite propeller blade today is an exacting and high-tech process. Alternative foam cores are now being studied to determine if they will perform correctly during infusion and impact tests. This technology is being applied to large fan cases, up to 9.1m/3 ft in diameter, manufactured by the RTM process. #aeroengines #aramidfiber #ndi. A decade ago, MoMA’s design collection picked up a composite fan blade from the GE90 jet engine that Kray helped create. Researchers at the University of Akron (Ohio), Ohio State University and Arizona State University have provided critical support for the NASA research. Optimization results of the composite blade design One of the many challenges facing the jet engine designer is to contain a failed fan blade within the engine, so that it threatens neither passengers nor airframe. “The manufacturing of composites remains a manual process… Automated tape laying and automated fiber placement technologies take a key enabling role in production of today’s — and tomorrow’s — composite-airframed commercial jets. The stiffness match at ply interfaces, therefore, results in inherent structural toughness. The fan blades and fan cases being made at the facility are a feature of the Rolls-Royce UltraFan engine demonstrator, a new engine design which will reduce fuel burn and CO2 by at least 25% compared to the first Trent engine. NASA initiated several research efforts to reduce risk, which included improving the fidelity of the design process. Because the part profile varies in diameter, particularly in flange areas, hoop (circumferential) fiber lengths in the fan case should differ. 1$6$ 67, 3URJUDP LQ 3UR¿OH 6LQFH LWV IRXQGLQJ 1$6$ KDV EHHQ GHGLFDWHG WR WKH DGYDQFHPHQW RI DHURQDXWLFV DQG VSDFH VFLHQFH 7KH 1$6$ 6FLHQWL¿F DQG 7HFKQLFDO ,QIRUPDWLRQ 67, SURJUDP SOD\V … #aeroengines #aramidfiber #ndi. Out-of-autoclave prepregs: Hype or revolution? Oven-cured, vacuum-bagged prepregs show promise in production primary structures. After it is shipped to the component fabricator, the preform is simply wound onto the mandrel of a mold tool, where it is impregnated with resin via resin transfer molding (RTM) or vacuum-assisted RTM (VARTM), whichever is chosen by the part manufacturer. will develop & produce a new all-composite engine fan blade to reduce emissions. The engineering and manufacturing development of the wide chord hollow titanium fan blade is described by Miller (1996) as, “an excellent example of simultaneous engineering-design for a controllable manufacturing process as well as for product duty.” It is also noteworthy that the hollow titanium fan blade design and development began at the time that the original RB211 PMC fan blade … 5 Axis OneCNC CAD CAM CNC Turbine Blade Manufacture - Duration: 4:18.

Fan blades are among the most important components of an aircraft engine. A&P's triaxial braid, however, is formed in close proximity to the capstan, as it is being wound onto the capstan. The length of each tow is determined independently of the others, as it is drawn around the capstan's cir-cumference. Process steps for fan-blade development in ASC’s PDC include 3-D weaving of the preform (pictured here); forming and drying of the preform; placement of the shaped preform into the RTM tool (next photo); tool insertion into the press and injection of heated resin, followed by cure; demold of the still hot part (thrid photo down) and final finishing operations. as well as numerous destructive and non-destructive testing technologies. Nick Kray is no Picasso, yet his work is on display at New York’s Museum of Modern Art. The project involved improvisation of fan design by selecting the most appropriate aerodynamic blade … Each blade uses hand-laid carbon fiber prepreg as many as 1700 layers, and then it is cured and finished with an autoclave. %PDF-1.5 GKN took over Filton wing component and assemblies manufacturing unit and Filton-West is their new production plant making wing spars and trailing edge for A350. COMPOSITES MANUFACTURING Materials, Product, and Process Engineering As the capstan turns, the tows that form the braid are drawn from spools through the braiding apparatus. Together, the projectors and software simplify and accelerate manual composite layup processes. Innovative use of carbon-fiber braid yields a ductile structure that resists blade impact. Results were used to analyze and predict the blade dynamics during a blade out event, as well as to predict the impact events. Bob Griffiths Share. In this way a component with varying diameters along its length can have a reinforcement with straight hoop fibers at all points, including the most critical area of the flanges. Various infusion processes will provide a method of impregnating the resin into the fibers at minimum recurring cost. A ceiling fan blade includes a foamed layer, two paper layers, and two cover layers. The GEnx engine fan blades that power the Boeing 787 and Boeing 747-8 aircraft also use carbon fiber composite materials. Five stacks are adopted here. In many low cost composite manufacturing instances reliability is performed as a subjective and qualitative step rather than incorporating a quantifiable reliability metric. Section 4.0 describes the ply lay-up tailoring using optimization methods, along with the mathematical optimization problem formulation. 4 0 obj A two-step process was proposed for the structural integration of the damping devices into a full composite fan blade. Lengthy and expensive financial challenges, Rolls remains bullish about the long-term market for the Trent 1000.

One, the softwall fan case, features a casing of aluminum, over-wound with dry aramid fibers. will develop & produce a new all-composite engine fan blade to reduce emissions. There has been an evolutionary change in the design, size, structures, materials, and manufacturing process of fan blades over the past few decades. This video takes you on a virtual tour of MFG’s state of the art, 315,000 sf blade manufacturing facility in Aberdeen, South Dakota. At the blade construction booth, composite manufacturers working at Airbus Helicopters’ La Courneuve blade manufacturing facility, just down the road from Le Bourget, shared their experiences and encouraged the next generation of students to join their ranks. Composites are, after all, the only material that that is made as the part is made, and when you consider the host of fibers, resins and manufacturing processes available, the complexity can be a blessing and a curse. The fan blades of GE90 are 1.2m long. 3 0 obj Priority date (The priority date is an assumption and is not a legal conclusion. Cost analysis of composite fan blade manufacturing processes. In earlier work at NASA, damage testing was initially undertaken on flat panels to compare the CFRP panels with aluminum panels, using an air gun, with gelatin packs and then metal blade simulators as the projectiles. A comparison of the hole sizes generated in a composite panel with that in the datum aluminum panel (representing a typical metal fan case) was very encouraging, since the much smaller hole created in the CFRP structure indicated that there would be a reduction in the stress level in a blade-damaged CFRP fan case, when out-of-balance loads were inflicted by an asymmetric fan. Large blades have been made by filament and tape winding in glass-reinforced plastic, hand-laminated wood/epoxy, aluminum, and steel. A FBO event may be caused by fatigue failure Abstract: The disclosed composite airfoil includes a three-dimensional composite core extending longitudinally and having a chord-wise direction. Passive damping concepts were first validated on carbon fibre reinforced epoxy composite plates and then implemented in a 1:5 model of an open rotor blade manufactured by resin transfer moulding (RTM). Process steps for fan-blade development in ASC’s PDC include 3-D weaving of the preform (pictured here); forming and drying of the preform; placement of the shaped preform into the RTM tool (next photo); tool insertion into the press and injection of heated resin, followed by cure; demold of the still hot part (thrid photo down) and final finishing operations. Triaxial braiding provided an automated method of laying up the fibers in the correct orientation. EXPERIMENTAL IMPACT TESTING AND ANALYSIS OF COMPOSITE FAN CASES By Andrew Joe Vander Klok For aircraft engine certification, one of the requirements is to demonstrate the ability of the engine to withstand a fan blade-out (FBO) event. The blade’s onyx black sinuous curves are pleasing to look at, but for Kray they are no longer state of the art. In order to achieve this, researchers had to develop a new understanding of blade trajectory in blade-out scenarios. A carbon composite casing would save weight, but could it be designed to behave in a ductile manner during a blade impact? NASA is planning to perform impact testing and post-impact loading on composite fan cases from the SBIR program. Google has not performed a legal analysis and makes no representation as to the … Rolls-Royce has already conducted blade-off and birdstrike tests for this blade which have proved the concept. Besides, the present invention is made of foam material and paper instead of steel bars, so the ceiling fan blade is light-weighted (about 40-50 g). The relative manufacturing costs were estimated for large high technology fan blades prepared by advanced composite fabrication methods using seven candidate materials/process systems. ... GEnx carbon fiber composite fan blades. United States Patent Application 20110038732 . The new carbon composite fan blades will debut in the GE9X, according to a GE Reports article. 7�bs����� endobj <> Composite fan blade containment case. Naval architects reveal design, tooling and material selection guidelines for a new sportfishing powerboat. It has leveraged the success of this product to introduce additional fan blades on the GEnx Engines that power the Boeing 787 and Boeing 747-8. The braid is designed so that, when flattened, it is the correct width to cover the developed length of the fan case and the flanges. What is Aeroengine Fan blade? It is expected that the CFRP case will be more successful than the metal case, with the naturally good crack resisting properties of the braided structure being sufficient to maintain the case's residual integrity. Other equipment for blade manufacture includes a new five-axis machining system for drilling, milling and sawing of the composite blade root area. Such cases are usually constructed with a honeycomb cored sandwich structure. A&P's fan case braiding system enables formation of a reinforcement preform that conforms to a fan case design profile and maintains its cross-sectional geometry during shipping and handling, prior to molding. %���� In fact, composite fan blades have certain advantages for blade-off failures. “It’s a good profession. A ceiling fan blade includes a foamed layer, two paper layers, and two cover layers. TPI’s extensive experience in high-volume high-quality wind blade production gives us a uniquely innovative and detailed application of the design for manufacturing process in collaboration with its customers. At Hartzell, we pull carbon fiber socks over a solid foam core, then inject resin with a vacuum pump and cure the blade after it’s put into the mold and pressure is applied. It is designed to permit a broken blade to pass through its aluminum component, where it is stopped and contained within the external aramid fiber wrap. Because the application of this technology is targeted at a number of different engine companies, each with its own supply base, NASA needed an automated method of laying up a robust preform that subsequently could be shipped to a variety of composite fabricators for conversion into a composite component. The paper layers are positioned on two opposite faces of the foamed layer respectively. Source: A&P TechnologyA fan case made from A&P's braided preform, showing the integral flanges and the profile formed on the capstan. After cure is complete, it is removed from the mold, and refined to precise standards. It's well understood that composites manufacturing in general can be a complex and complicated process. Composites manufacturing processes usually involve multiscale models in both space and time, highly non-linear and anisotropic behaviors, strongly coupled multiphysics and complex geometries. There are two approaches to blade containment currently in common use. GKN took over Filton wing component and assemblies manufacturing unit and Filton-West is their new production plant making wing spars and trailing edge for A350. GE has had a history with composite fan blades on the GE90 series of engines since the early 1990s for the B777 programme, although these have always had a very high labour content within their manufacturing processes.

There are two approaches to blade containment currently in common use. There are three types of composite manufacturing processes: open molding, closed molding and cast polymer molding. Even with the help, making the blade was a hard climb. Rolls-Royce has already conducted blade-off and birdstrike tests for this blade which have proved the concept. The key component is its reinforcement, a triaxial braid developed by A&P. The flat tape is wound around a capstan that incorporates the profile of the particular containment case for which the braid is intended. They formed a joint-venture called CFAN and built a new composites factory in San Marcos, Texas. It's well understood that composites manufacturing in general can be a complex and complicated process. <>/Font<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> This involves a cyclic fatigue test representing the number of cycles experienced by the damaged case during engine shutdown. Measurement of damage propagation then will be analyzed and used to develop the capability to predict success or failure of the containment casing. There are a variety of processing methods within these molding categories, each with its own benefits. Aeroengine Fan blades are among the most important components of an aircraft engine. Cost analysis of composite fan blade manufacturing processes eBook: NASA, National Aeronautics and Space Administration: Amazon.in: Kindle Store The following is a brief discussion of the current methods for manufacturing composite blades in order that the relation of material choice, design, and manufacturing method to fatigue life may be presented. GAS TURBINE ENGINE COMPOSITE BLADE . The foamed layer is formed by foaming a polystyrene material. It is designed to permit a broken blade to pass through its aluminum component, where it is stopped and contained within the external aramid fiber wrap. When replacing aluminum with CFRP, weight savings are achieved, but few applications can justify a significant cost premium for the lighter weight. A two-step process was proposed for the structural integration of the damping devices into a full composite fan blade. A further program goal was to identify new nondestructive evaluation (NDE) and nondestructive inspection (NDI) methods for the braided composite structures. At Hartzell, we pull carbon fiber socks over a solid foam core, then inject resin with a vacuum pump and cure the blade after it’s put into the mold and pressure is applied. Pultrusion is an automated process that allows the continuous production of carbon profiles (24/7 production). Safran and Albany inaugurate third composite fan blade production plant for LEAP engine, in Mexico Querétaro (Mexico), February 21, 2018 Safran and Albany inaugurated today, in Mexico, a third joint manufacturing plant to make composite parts for the LEAP aircraft engine. The key material properties are the ductility of the metal cases and, in the case of the softwall system, the energy absorbing capabilities of the aramid fibers. Carbon fiber is on the order of 2.5 times less dense than the Titanium used on older fan blades. High-speed video of GEnx engine blade manufacturing at CFAN offers a great look at the complexity of composites manufacturing. The technology has been successfully demonstrated for the hardwall-type case and may find its first application on a turbofan jet engine built by Williams International (Walled Lake, Mich.). After the initial blade impact test, the fan case will be loaded in a manner similar to that experienced during the post blade-loss regime. This is the question being answered by A&P Technology (Cincinnati, Ohio) and the NASA Glenn Research Center (GRC, Cleveland, Ohio) in a project funded by the NASA Aviation Safety and Security Program. Examples of companies investing in manufacturing R&D in the UK include: Clipper Windpower - The progressive damage analysis of the composite fan blade shows that ply damage is initiated at a speed of 4870 rpm while blade fracture takes place at 7640 rpm. A&P's solution for this requirement was ingenious. Impact tests need to be performed in a manner that replicates the blade-to-case impact dynamics that are likely to occur in an actual engine blade failure. Background To conduct this study, GEC has assembled a project team that includes experts in all areas of wind turbine blade design, analysis, manufacture, and testing. NASA research into both softwall and hardwall configurations has led to a new generation of carbon fiber-reinforced polymer (CFRP), which promises to match the strength and ductility properties of a ductile metal casing but at a much lower weight. Also, the cost is reduced. There has been an evolutionary change in the design, size, structures, materials, and manufacturing process of fan blades over the past few decades. Not only does the fan case structure have to withstand the blade impact, but it must also retain its structural integrity while the engine is shutting down. In 2003, Roberts began extending the successful research performed during the Ultrasafe Program to higher technology readiness levels (TRLs) in the NASA Aviation Safety and Security Program (AvSSP). It's also an extremely different process than building Ti blades; most OEM's don't have the resources to be developing both at the same time. The composite blade 10 manufacturing process begins with the cutting of material into the proper ply section 40a-40g shapes which when positioned properly in the tooling 420, using the method of the present invention, will compact under heat and pressure to produce a composite blade 10 in accordance with the embodiments of the present invention as described above. The operating conditions and the major material indices which influences the performance We focus on consistency and quality control across our facilities, using hands-on training methods and employing repeatable manufacturing processes. Assuming this can be achieved at an acceptable cost, the technology could be launched on a new family of jet engines currently under development at Williams. Jim Dorer, William's Compression DTP team engineering specialist, believes the company may achieve up to a 40 percent weight saving over the metallic datum. endobj One, the softwall fan case, features a casing of aluminum, over-wound with dry aramid fibers.
