I like ribs spaced no more than 2-1/2" apart and even closer when the wing will be fully sheeted. Several of the interior waste pieces moved around in an uncomfortable way, and two of the trusses bent out (got too thin) as the router bit pushed them sideways. the detail design of a wing rib under different loading conditions is subjected to buckling, it is found to be safe. I see the concern but ribs on most airplanes are not heavily loaded and even aerobatic airplanes are using routed ribs now. milling machine. Have you looked into this?Please don't take this as a disparaging comment, it's a great use for a CNC router, especially if it gets another airplane in the air. Having dealt with wooden wing ribs I can see where this will save the builder lots of time and money. You want extra room for clamping down the outer edges with screws, cam locking devices, or even double-sided tape.                     Mazes for more than one player The wing ribs are joined to the spar to give the airfoil shape, making lift possible and distributing the load over a larger surface area. Othervise it is clever idea to simplify ribs manufacturing and to speed up the process. 70% of the work is in making the ribs and making them to the correct size. To me, this is amazing stuff, I used to hand cut all of these projects. I just glued the pieces together while they lay on the garage floor. available elements is no more a problem. on Introduction. on Step 13. I powered the machine and computer and opened up Mach3. Kitfoxes have routed wood ribs but the factory does them by hand. haha. X, Y and Z must be zeroed. I'd be curious to run a stress test to failure on this and a traditional built-up rib. The 1/4" center rib should be angled 50 to produce the proper dihedral angle. Seems obvious, doesn’t it? I and C shapes are the cross-sectional configuration. Most of the time, this point will be the top-lower-left corner of the drawing.                     Giant Spirographs using chalk for outside This is the interfaces that actually translates the g-code into movement by the router. (http://www.cnccookbook.com/CCCNCGCodeCourse.htm) Regarding the design of the ribs themselves, as mentioned, 1 is a classic truss. Using .002 gets the bit located in space just half-a-hair above the material. Most great advances come from trying something new. Make sure that the piece you load on the machine is bigger than the project. X-acto, utility knife, something sharp                     Full Busts Aircraft Structures 1. this also allowed us to pin the material - usually wood - down with panel pins. Fig. settings, Spars, jigs and other FAA Approval. The spars are the wing's main structural elements and are usually made of wood or aluminum. Here we go, ignore this at your own peril. On our homemade CNC machine, is a Porter Cable Trim Router  As I had selected Baltic birch plywood, I chose a ¼”shank 1/8” end mill. By analogy with the anatomical definition of " rib ", the ribs attach to the main spar, and by being repeated at frequent intervals, form a skeletal shape for the wing. In standard rib building (as I understand it) the wood grain runs parallel to each member, whereas with plywood the grain is going every which way. current design philosophy made popular by 3D aircraft of spacing ribs 7" apart. Our router only goes one speed in rotation and maxes out at 25 linear inches per minute, so the only control we have is how deep it cuts per pass, and the inches per minute speed it travels thru the material. Finally, we concluded that initially the design is of 4.592 Kg & optimize up to 2.964 Kg, so that weight is reduce by 1.628 Kg KEYWORDS: Wing RIB, Current Report & Plate RIB using FEM Packages But if you're making something like a Pitts that puts heavy loads on the wing ribs, ultimate failure strength is by far the top priority. You really want to fire that thing up.                     Spirographs – small 8.5 x 11 Some very interesting results WILL occur and you really don’t want that experience. That’s the next project for us after this contest. And this will resulted in heaviest ribs, than odf classic design. Software packages are to be used to design an aircraft wing spar structure and Finite Element Method (FEM) also be used to calculate the stresses developed at each station for a given bending moment. Use that or wireless or whatever you move files with, from your cozy office to the cold and manly shop. WING is a USA manufacturer using state-of-the-art materials and technology to deliver a tougher and longer lasting boat.. I then  clicked the Reset button. Then I clicked the green button on the screen labeled Cycle Start. design sizing that includes many failure analyses at all load conditions for all areas of an airframe. (http://www.rhino3d.com/resources/display.asp?language=en&listing=545) Some CADs have CAM with them but they tend to be the pay-for types. Location & Hours. He also brought over his homemade CNC Router. Aircraft Structures II. The tooling bits, I’ve found, do break, and are pricey. on Step 3, I would like to know more about how you faired the rib profile before you created the "G" code. Writing skills Thanks. DevWing, the innovative application to draw ribbed wings Using DevWing you can create in a very simple way a ribbed wing drawing The Project Wizard will drive you to draw and cut the ribbed wing using a step by step approach. Smaller 3 or 4 rib pieces are better suited for smaller groups. Caps and diagonals should be much wider. Dust collection system wing drawing, The Project Wizard will drive you to draw and cut the ribbed wing using a Then took it to a local architectural copy shop (FedX-Kinkos would do) and had them make a digital file. (http://www.freecad.com/CAM_Programs/))  For those of you who want to learn about g-code there are sites that will show you what it all means. Last summer Mike and I began getting together at least once a week, or more, for what we called guy time. Patience Pin and glue the 1/2" wing tip pieces in place and add the W3 and W4 ribs. Using created circles at each intersection within the internal trussing, I smoothed and cleaned up the intersections, thus replacing gussets that would have been present if built the traditional way. At our monthly meeting of the Experimental Aircraft Association, I was telling the members that I had access to a CNC router. For those of you who are using a CAD program that does not have this function, you’re going to have to find a separate one to do this. This wing will … ---(If at all possible make or buy a dust collection system to keep the fumes and dust to a minimum. In the first variation lightening holes were made in similar ribs, then a three forty-eighths inch full plywood web was substituted for the three thirty-seconds inch web, and. longitudinal elements, Using DevWing you can create in a very simple way a ribbed They also sized it a bit to match the dimension given on the plans. No Cad skills are required! Wing Ribs The wing ribs are the largest templates in the plans set, and the one most vulnerable to dimension errors. For 25 years I was asked to build the most amazing things. I loaded the file into my CAD program and with node editing, smoothed the exterior curves, or as known in boat making, fairing the lines. Title of Thesis: ABSTRACT. Now is the time to really look at the product. On the other hand, a few plans only provide a small drawing of the wing rib showing its essential dimensions. Here is some links. Many tests were also made on parallel-chord specimens of truss and plywood forms in place of the actual ribs … It also provides the ability to print the design (wing ribs, fuselage sides, wing and tail plans) to any Windows supported printer and export design components to DXF files for import into other CAD programs such as AutoCAD. Our club of makers would continue to explore the vast world of CNC routing. We have in mind a large backlog of ideas that would be furthered by winning the PRS Standard 96-48-6 ShopBot . Glue About That full-Size Wing Rib Drawing . Aircraft Design. I have never been able to make a rib that I could use right off the CNC table without doing a lot of hand work to get the profile fair. The least is you may lose some steps in the g-code and get the remainder of the cut all cockety-wampuss, and the worst is flying bits of high speed steel flying around. In the original design, ribs of the BS-1 wing had full plywood webs with vertical angle blocks for brac-ing. CNC Wing Ribs: At our monthly meeting of the Experimental Aircraft Association, I was telling the members that I had access to a CNC router. When the detail design of a wing rib under different loading conditions is subjected to buckling, it is found to be safe.

Another way to make ribs for a tapered wing is manually plot or use rib-plotting software to draw each rib pattern individually. Test it, measure it, look it over closely. Considering his project is a bi-wing aircraft, and has 32 wing ribs, that’s a lot of tedious hours. Web and truss are the main types rib. The Grumman F3F was the last American biplane fighter aircraft delivered to the United States Navy (indeed, the last biplane fighter delivered to any American military air arm), and served between the wars. The traditional approach is to make a jig, take hundreds of small sticks and glue and staple them together. The Design of Airplane Wing Ribs The purpose of this investigation was to obtain information for use in the design of truss and plywood forms, particularly with reference to wing ribs. You have been at it for a while. Lastly, if the project is cut completely from the waste material, I have a template that will prove useful. Sad huh? It almost worked perfectly. Photography Skills                     Wood Blocks for printing from ancient lithographs 2 has the center of the rectangular rib filled in with metal and the center circular portion and edges made as an I beam for strength. So, I went back the CAD and placed a number of tabs around each part. Mostly I'm just curious. Riveting and spot welding are the I remove the waste sections, and vacuumed or blew off the dust so the machine is ready for the next experiment. Various loads are acting on rib like pressure load, inertia load etc. West - Corona, CA Midwest - West Chicago, IL For the following results, it was assumed, the a maximum of 60% sag occurs between two ribs. When the cycle ended, and the router came back to zero, I turned it off, then removed all the staples. You are on page 1 of 97. The lower end and free are getting better all the time. Just like your mother used to say “don’t forget your mittens”, remember the safety stuff. Staple gun ---Breathing – All materials have some dust created during the cut. EMC is the open-source Linux version, Next I loaded the g-code using a flash drive. I prepared to stop the cycle if it ran off in some bizarre direction. Due to the ribs, which add a spanwise component to the stress in the membrane, the true shape will be somewhere in between the 100% and the 0% shape. In the current report, a complete stress analysis for a wing box rib portion subjected to different kinds of loading is introduced. Now using the “section plane” button at each of the wing rib locations a cross-section of the wing will be generated. On top of this using 3M spray glue I attached the wing rib drawing that I plotted from the dimensions on the plans. . The traditional approach is to make a jig, take hundreds of … Most plans come with a full-size drawing of the wing rib(s). I've done some ribs for people too. What airplane is it for? This is my least favorite way as it is the most time-consuming, tedious and The intent of this research is to mature HyperSizer’s usability for final design and certification of traditional transport wing box structures. Ordinary rib will be superior as grain orientation and strength of the spruce (or douglas fir..) is way higher than of the plywood. (http://www.cncezpro.com/gcodes.cfm) In an aircraft, ribs are forming elements of the structure of a wing, especially in traditional construction. The backdraw of the plywood is also the grain orientation, and it can not be used to its best strenght. Wally.                     Patterns for Cabinet doors your drawing printed or the cutting path ready to be imported in your CNC I said I’d give a go. I had some cardboard to use for the test cut. DevWing Cam, the version of devWing with Cam features, can also create a Cam G-code is a language defining where the router must go to perform the task you have in mind and is generated by the CAM. I use Rhino 3D which has a feature in the view menu to place a background bitmap, jpeg also works. The higher end ones have a steep learning curve and take a while to be comfortable with. Cut the cardboard/plywood  larger than the project. step by step approach. . CAM generator FAA-PMA. Use at least a filter mask for non-toxic woods and cardboard something better for MDF and plastics. Faster tools. (http://www.guitar-list.com/download-software/convert-sketchup-skp-files-dxf-or-stl) Both the leading edge and the trailing edge of the wing may be straight or curved, or one edge may be straight and the other curved. Right? 7 years ago Also that it is oriented correctly in the X and Y plane. Yeah!!! Mach3, EMC, or similar (http://www.machsupport.com/) (http://www.linuxcnc.org/) The newest design from team AeroMax use many CNC done wooden plywood parts in the aeroplane structure. A primary focus of this report will be to I love it.                     Art prototypes Which brings us to the all-time favorite subject of OSHA,   da-da… SAFETY. Design and Structural Analysis of the Ribs and Spars of Swept Back Wing The aim of this paper work is to design and analyze the ribs and spars of a 150 seater regional aircraft for the stresses and displacements due to the applied loads. The ribs are then cut in pairs. Since the bottom center section sheeting covers the rib locations in this area, use the rib positioning lines which are shown beyond the leading and trailing edges. Share it with us! This resulted in some clever solutions using rather odd materials. Winfoil is a an aeronautical computer aided design tool for designing, analysing and modifying model aircraft. You do remember NOT to have the router on during this step. Wing Rib Stress Analysis and Design Optimization. Thank you for considering this submission Reply Regardless of the method, one wouldn’t want the highly rotating router bit or the router itself crashing into something hard and unyielding. Some are free, some are not. About this time Mike introduced me to Instructables.com and I was hooked. 2D More tools We would work on some idea, hack, project, or repair of some item with what we had in the shop.                     Multi-level mazes For this run I had the cardboard template to trace on a piece of Birch plywood. Better Materials: Wing uses polyurethane exclusively in the construction of our tubes, sponsons and inflatable boats.The expected service life of a polyurethane tube is 7 – 8 years versus Hypalon which is only five. This means it is strong (thicker shank), and will cut 1/8” wide with a square bottom. There are so many design programs out there (http://crunkish.com/top-ten-cad-software/) (http://www.freecad.com/). Baltic birch plywood – ¼” 5 ply or similar I'm building a flying wing right now too. Tooling Bits Some drawing (CAD) programs have no way to get g-code from them. Three versions of Many treacherous opportunities lie here. them. I used foam sanding pads, and smoothed all the surfaces, then cleaned with. We got it up and running and have been creating a number of interesting projects that are being submitted for this contest. The ribs form part of the boundary onto which the skins are attached, and support the skins and stiffeners against buckling.                     Negative busts DESIGN AND ANALYSIS OF A MULTI-SECTION VARIABLE CAMBER WING. Computer For this we did a comparative study on particular 150 seater regional aircraft [1][2][3]. 1 of wood, 2 of stamped metal. Wing design can vary to provide certain desirable flight characteristics. I have two Marske Flying wings that I want to build. The plywood was three thirty-seconds inch thick with mahogany faces and poplar core. 2.0 Wing Box Rib Design The primary components in a commercial aircraft wing box are the skin panels, the stringers, the spars and the wing box ribs. Good job. Be slow and careful to NOT run the bit into the material or hold-down clamps. Wish I had done it earlier.) Our homemade CNC can cut 31” x 21” and cuts at a maximum of 25”/ min. Not        too loud as you want to lightly hear the machine as it runs, giving you a heads-up to any problems. My program has CAM output, so the g-code was created, and ready for the homemade CNC machine. But we have to get off on the right foot, or inch, or thousandths of an inch. I was given the sheet of blueprints (actually white zeroxed copies) to work from. Designed specifically for holding wing ribs… Before any machinery is turned on, install the bit into the router you have. Just a CNC tip - We often for complicated cuts used to print out the drawing - full sized - and the lightly tack glue to the material. I have been also researching the design of my own and came up with a plan for a sporty looking, low wing, part 103. Rick Shore, Participated in the Make It Real Challenge.                     Cameos I then use the control point curve to trace the outline and then scale it to the right size in the "transform 2D" function. Jump to Page . that way we could see a) that the material is big enough - b) where to put the hold down clamps that is going to be out of the way.We always used a piece of sacrificial MDF under the material so we could cut all the way through. I could place staples more accurately to secure the material safely. Control at various operating speeds, the amount of lift generated, balance, and stability all change as the shape of the wing is altered. Here is a small selection of my personal list of projects: Tests were made on many designs of wing ribs, comparing different types in various sizes. By that time I have lost the exact shape and the rib is worthless. 2: Wing section, showing various degrees of the cover material sagging between ribs. Once over the zero, lower the bit ever so gently down to just above the top of the piece. (Tabs are small bits of the wood that hold all the various parts together. and go forth and back among the project wizard panels to retouch Sometimes it's better to just see if you can get something to work since everything is a great compromise in design anyway. MY WING RIB JIG: MY WING RIB JIG: My jig is made up of two 3/8" plywood 70" x 10" pieces glued (Elmer’s wood glue) together to form a rigid base. Then press the push pin through the hole in the angle and into the building board. (Computer Aided Manufacturing) Did you make this project? Ok, the condensed version:                     Negatives for molds You are impatient (well that, at least, describes me at times). I hope you can help me. Then under “section plane” select generate section. Plan B was run thru successfully. I never make that mistake. Large scanner The interplay between us was so fun we began to invite others to our “club”. No Cad skills are required! Search inside document . To download devWing LE, devWing or devWing Cam see the. I like to put on noise cancelling earphones with my favorite music playing in the background. Wing ribs may be constructed of wood or aluminum, and aluminum ribs may be either formed sheet or formed extrusion. Quickly, one member asked if I could cut out wooden wing ribs. Drawing a ribbed wing with a complex wing plan, different airfoils and a lot of Now, only 31 more. I've owned a shopbot for 15 years and after you have the machine it's all about the CAD skills isn't it :) Have fun, I'll post my project "floater wing" soon. Sweet! The Riblett 66” wing is 1.5” thicker and 3” longer than the traditional Piper wing. Things you need / Materials and equipment list: Download Now. Mach3 works with windows. Contact. By a 3D preview you can check every step of the creation of the wing, Quickly, one member asked if I could cut out wooden wing ribs. We offer 6 different wing designs; Piper Cub (US35B airfoil), Taylorcraft (23012 airfoil), Citabria / Champ (NACA 4412 airfoil), and 3 different Riblett 56”, 63” & 66” chords (GA 30613.5). In just a few minutes you can have :). (http://solsylva.com/cnc/vacuum.shtml). How it works: just position the 90 degree aluminum angle next to the item you want to hold. 7.You now have your smaller tapered rib! The wing tip and root were then selected as the faces to remove, and what is left is the wing skin. Now I could move the non-running router around to position the 3D coordinates(X, Y and Z) of the bit by using the number pad on the keyboard or an separate number pad. Well done! CNC Router   (www.100Kgarages.com) It acts as a load distributor. I suggest that a comparative load test should be done between that CNC-ed rib and ordinarry build up rib from spruce sticks. 7 years ago Stabilize the cardboard (later the plywood). Sandpaper or foam blocks, (Things I need) placement, Wing panel airfoils and This project would be a fine experiment. Fore Ribs. ---Ears - CNC machines are loud. Check out Sketchup (free) with the ruby script that allows output in .stl and .dxf formats. Then I place a feeler gauge below the bit and, extremely slowly, move it down to just touch the gauge. The 4’ x 8’ table and 300”/min will vastly improve our ability to produce prototypes, develop and improve designs, create larger projects and test out 2.5D, then move to full 3D sculpting. Therefore the inner wall of the wing skin is the rib shape. Make sure you look at what they can import and export. While the skin panels, the stringers and the spars are main load carrying members in the wing box, the ribs only contribute little to the overall CATIA V5 is used for rib modeling.                     Bas-reliefs The efficient design will be achieved by the use of strength of material approach. 2.5D 8 years ago From these, you are supposed to make your own full-size rib layout. Pure plywood ribs should be designed for that lower strength of the material.                     Picture frame mazes Thus a Maker Space has taken over my shop. If all is going well, just watch and enjoy the moment. I used a staple gun with ¾” staples around the outer edges of the cardboard and the baltic birch, out of the way of where the router bit would travel. I have been researching building aircraft for a long time and want an ultralight (can't solo- not old enough) but none of these airplanes are as strong as I would like or are too much. Since the ribs compose an appreciable part of the wing, an accurate design for the wing rib that guarantee the necessary strength with minimum weight. Much better than double sided tape and easier than various clamping systems. http://crunkish.com/top-ten-cad-software/, http://www.guitar-list.com/download-software/convert-sketchup-skp-files-dxf-or-stl, http://www.rhino3d.com/resources/display.asp?language=en&listing=545, http://www.cnccookbook.com/CCCNCGCodeCourse.htm, Plywood Mandala Carving Without CNC Machine. Vector Drawing Program The spar webs and caps are collectively referred to as the wing spar. If it needs improving, return to Step 4, and go for Plan-C, or Plan-D, etc.                     Interchangeable mazes of increasing difficulty devWing are available, see the. You will need a full-size rib layout to construct a plywood jig. It’s a wonderful world! ribs in aircraft wing. The 5-bone Carvery Rib of Beef on the bone is a classic - beautifully marbled meat with just enough fat, cooked on the bone to provide full flavours and moist tenderness. I then met with the aircraft builder for his approval. Then again, plywood would have increased strength in other directions, and wouldn't have failure-prone joints. Wing Ribs: The ribs are spaced equidistant from one-another (as far as is practical) and help to maintain the aerodynamic profile of the wing. 3D At last the fun began. 7 years ago It’s finally time to turn the router on and start the sequence of cutting from Mach3. Bigger tools Off and cutting. I have a background in fabricating Museum, Zoo and Nature Center exhibits. I've noticed that many times we get buried in conventional thinking that is based on a theory nobody fully understands in aviation. I taped the relevant portions together and traced the image to be cut on white butcher paper. on Introduction. This will be important in moving your drawing files to the CAM generator (more about that later). 6.Now swing the rib pattern so the bottom of the rib pattern matches up to the same point and again trace the bottom edge of your rib pattern onto the paper. I use a face shield.                     Giant mazes on a half sphere to be played by young children on Introduction, Oh yes, it's absolutely much faster and very likely better use of materials. Two methodologies for the design of the wing rib are presented. Marco Pinto's rib CAD files are great. Wing Ribs and Parts; Accessories; Filters. W2 ribs in place. 8.Do the same for each rib in your tapered wing and you will have all of your tapered rib patterns ready to use. Ribs definition and They are less thick than the plywood, short in length, and are easily cut with an x-acto knife.) Drawing, compatible with devCad Cam Pro 2. I wouldn’t know that, but, there are a wide range of band aids and compresses readily available in our shop, just in case. Price $ $$ $$$ $$$$ $$$$$ Quick Shop. Remember the adage that computers, (along with dangerous machines attached to them) only do what you tell them to do, not what you want them to do. Try the free ones, or the trial downloads,  and spend some time assessing their capabilities. I was enlarged 1.6%. (CAD – Computer Aided Design) optimize an aircraft wing spar beam for a six seated aircraft.                     Sculpture Plus, in the most-recent printing of the plans, the templates are actually reduced to fit on a single 8x10 page rather than the 11x17 fold-out. 73994554-44848151-WING-SPAR-Presentation. Many theories are just rumors even. ---Eyes and face – Flying objects do sometimes come from the machine, best to protect them. Place the item against the vertical face of the angle and hold in place with the mini clamp. Most of the time, it takes several tests and iterations to get it right.
