Thanks. That’s the next project for us after this contest. I used foam sanding pads, and smoothed all the surfaces, then cleaned with. Once over the zero, lower the bit ever so gently down to just above the top of the piece. 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. Thank you for considering this submission X-acto, utility knife, something sharp I see the concern but ribs on most airplanes are not heavily loaded and even aerobatic airplanes are using routed ribs now. Considering his project is a bi-wing aircraft, and has 32 wing ribs, that’s a lot of tedious hours.                     Negatives for molds on Step 13. Download Now.                     Bas-reliefs 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. For this we did a comparative study on particular 150 seater regional aircraft [1][2][3]. 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.                     Patterns for Cabinet doors 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. 3D When the detail design of a wing rib under different loading conditions is subjected to buckling, it is found to be safe. Most great advances come from trying something new. I taped the relevant portions together and traced the image to be cut on white butcher paper. on Introduction. I could place staples more accurately to secure the material safely. Try the free ones, or the trial downloads,  and spend some time assessing their capabilities. It’s finally time to turn the router on and start the sequence of cutting from Mach3. current design philosophy made popular by 3D aircraft of spacing ribs 7" apart. Use that or wireless or whatever you move files with, from your cozy office to the cold and manly shop. This is my least favorite way as it is the most time-consuming, tedious and You will need a full-size rib layout to construct a plywood jig. Share it with us! On the other hand, a few plans only provide a small drawing of the wing rib showing its essential dimensions. 8 years ago I like to put on noise cancelling earphones with my favorite music playing in the background. Contact. (CAD – Computer Aided Design) Various loads are acting on rib like pressure load, inertia load etc. Glue                     Giant mazes on a half sphere to be played by young children (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. Now using the “section plane” button at each of the wing rib locations a cross-section of the wing will be generated. (http://www.rhino3d.com/resources/display.asp?language=en&listing=545) A primary focus of this report will be to                     Giant Spirographs using chalk for outside Fore 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. Mach3, EMC, or similar (http://www.machsupport.com/) (http://www.linuxcnc.org/) When the cycle ended, and the router came back to zero, I turned it off, then removed all the staples. Wing Rib Stress Analysis and Design Optimization. The intent of this research is to mature HyperSizer’s usability for final design and certification of traditional transport wing box structures. The spars are the wing's main structural elements and are usually made of wood or aluminum. 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. 2D Ordinary rib will be superior as grain orientation and strength of the spruce (or douglas fir..) is way higher than of the plywood. We would work on some idea, hack, project, or repair of some item with what we had in the shop. Did you make this project? 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. I was enlarged 1.6%. Baltic birch plywood – ¼” 5 ply or similar The traditional approach is to make a jig, take hundreds of small sticks and glue and staple them together. To download devWing LE, devWing or devWing Cam see the. Some CADs have CAM with them but they tend to be the pay-for types. I and C shapes are the cross-sectional configuration. Much better than double sided tape and easier than various clamping systems. It’s a wonderful world! Check out Sketchup (free) with the ruby script that allows output in .stl and .dxf formats. Aircraft Structures 1. No Cad skills are required!                     Sculpture Drawing a ribbed wing with a complex wing plan, different airfoils and a lot of 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. Place the item against the vertical face of the angle and hold in place with the mini clamp. I like ribs spaced no more than 2-1/2" apart and even closer when the wing will be fully sheeted. I use a face shield. I powered the machine and computer and opened up Mach3. For this run I had the cardboard template to trace on a piece of Birch plywood.                     Negative busts Caps and diagonals should be much wider. Then I place a feeler gauge below the bit and, extremely slowly, move it down to just touch the gauge. this also allowed us to pin the material - usually wood - down with panel pins. This project would be a fine experiment. The Riblett 66” wing is 1.5” thicker and 3” longer than the traditional Piper wing. 8.Do the same for each rib in your tapered wing and you will have all of your tapered rib patterns ready to use. Price $ $$ $$$ $$$$ $$$$$ Quick Shop. design sizing that includes many failure analyses at all load conditions for all areas of an airframe. It almost worked perfectly. They are less thick than the plywood, short in length, and are easily cut with an x-acto knife.) Stabilize the cardboard (later the plywood). Some are free, some are not. Marco Pinto's rib CAD files are great. 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. Rick Shore, Participated in the Make It Real Challenge. Using .002 gets the bit located in space just half-a-hair above the material.

Reply (http://www.cncezpro.com/gcodes.cfm) Staple gun 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 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. Control at various operating speeds, the amount of lift generated, balance, and stability all change as the shape of the wing is altered. Aircraft Design. Now is the time to really look at the product. Lastly, if the project is cut completely from the waste material, I have a template that will prove useful. This will be important in moving your drawing files to the CAM generator (more about that later). 7 years ago Off and cutting. Use at least a filter mask for non-toxic woods and cardboard something better for MDF and plastics. Right? CATIA V5 is used for rib modeling. ribs in aircraft wing. I just glued the pieces together while they lay on the garage floor. You do remember NOT to have the router on during this step. Ok, the condensed version: 7.You now have your smaller tapered rib! 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. Just like your mother used to say “don’t forget your mittens”, remember the safety stuff.                     Spirographs – small 8.5 x 11 The newest design from team AeroMax use many CNC done wooden plywood parts in the aeroplane structure. He also brought over his homemade CNC Router. Last summer Mike and I began getting together at least once a week, or more, for what we called guy time. The 1/4" center rib should be angled 50 to produce the proper dihedral angle. For 25 years I was asked to build the most amazing things. Mach3 works with windows. What airplane is it for? More tools (http://www.guitar-list.com/download-software/convert-sketchup-skp-files-dxf-or-stl) CAM generator In an aircraft, ribs are forming elements of the structure of a wing, especially in traditional construction. This means it is strong (thicker shank), and will cut 1/8” wide with a square bottom. Our homemade CNC can cut 31” x 21” and cuts at a maximum of 25”/ min. In the original design, ribs of the BS-1 wing had full plywood webs with vertical angle blocks for brac-ing. My program has CAM output, so the g-code was created, and ready for the homemade CNC machine. on Introduction, Oh yes, it's absolutely much faster and very likely better use of materials. Be VERY careful, they are quite sharp.                     Full Busts 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. wing drawing, The Project Wizard will drive you to draw and cut the ribbed wing using a Pure plywood ribs should be designed for that lower strength of the material. From these, you are supposed to make your own full-size rib layout. Test it, measure it, look it over closely. Then again, plywood would have increased strength in other directions, and wouldn't have failure-prone joints. 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. 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. This wing will … The interplay between us was so fun we began to invite others to our “club”. 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. Search inside document . ---Eyes and face – Flying objects do sometimes come from the machine, best to protect them.                     Multi-level mazes I wouldn’t know that, but, there are a wide range of band aids and compresses readily available in our shop, just in case. Wing Ribs and Parts; Accessories; Filters. Vector Drawing Program About That full-Size Wing Rib Drawing . 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. 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. Writing skills You want extra room for clamping down the outer edges with screws, cam locking devices, or even double-sided tape. I said I’d give a go. on Introduction. Here is some links. Othervise it is clever idea to simplify ribs manufacturing and to speed up the process. the detail design of a wing rib under different loading conditions is subjected to buckling, it is found to be safe. Fig. But we have to get off on the right foot, or inch, or thousandths of an inch. At our monthly meeting of the Experimental Aircraft Association, I was telling the members that I had access to a CNC router. Which brings us to the all-time favorite subject of OSHA,   da-da… SAFETY. Smaller 3 or 4 rib pieces are better suited for smaller groups. There are so many design programs out there (http://crunkish.com/top-ten-cad-software/) (http://www.freecad.com/). 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. EMC is the open-source Linux version, Next I loaded the g-code using a flash drive. The tooling bits, I’ve found, do break, and are pricey. Our club of makers would continue to explore the vast world of CNC routing. 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. On top of this using 3M spray glue I attached the wing rib drawing that I plotted from the dimensions on the plans. The efficient design will be achieved by the use of strength of material approach. Quickly, one member asked if I could cut out wooden wing ribs. haha. Pin and glue the 1/2" wing tip pieces in place and add the W3 and W4 ribs. Many theories are just rumors even. I had some cardboard to use for the test cut.                     Wood Blocks for printing from ancient lithographs Now, only 31 more. Bigger tools I love it. optimize an aircraft wing spar beam for a six seated aircraft. available elements is no more a problem. You are impatient (well that, at least, describes me at times). And this will resulted in heaviest ribs, than odf classic design. FAA-PMA.                     Art prototypes DevWing Cam, the version of devWing with Cam features, can also create a Cam 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. Mostly I'm just curious. W2 ribs in place. You have been at it for a while. Three versions of 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. Turn the router on first. Well done! Make sure you look at what they can import and export. CNC Router   (www.100Kgarages.com) In just a few minutes you can have I remove the waste sections, and vacuumed or blew off the dust so the machine is ready for the next experiment. 7 years ago FAA Approval. 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. Most of the time, this point will be the top-lower-left corner of the drawing. Sweet! Many treacherous opportunities lie here. Jump to Page . Therefore the inner wall of the wing skin is the rib shape. Dust collection system Tests were made on many designs of wing ribs, comparing different types in various sizes. 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. Having dealt with wooden wing ribs I can see where this will save the builder lots of time and money. Here is a small selection of my personal list of projects: Then I clicked the green button on the screen labeled Cycle Start. We got it up and running and have been creating a number of interesting projects that are being submitted for this contest. 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. Not        too loud as you want to lightly hear the machine as it runs, giving you a heads-up to any problems. In the current report, a complete stress analysis for a wing box rib portion subjected to different kinds of loading is introduced. 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. The backdraw of the plywood is also the grain orientation, and it can not be used to its best strenght. Another way to make ribs for a tapered wing is manually plot or use rib-plotting software to draw each rib pattern individually. . 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. The lower end and free are getting better all the time. 70% of the work is in making the ribs and making them to the correct size. them. I've done some ribs for people too. Quickly, one member asked if I could cut out wooden wing ribs. 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. ---(If at all possible make or buy a dust collection system to keep the fumes and dust to a minimum. Wing ribs may be constructed of wood or aluminum, and aluminum ribs may be either formed sheet or formed extrusion. placement, Wing panel airfoils and 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. You really want to fire that thing up. Wing Ribs The wing ribs are the largest templates in the plans set, and the one most vulnerable to dimension errors. Then took it to a local architectural copy shop (FedX-Kinkos would do) and had them make a digital file. 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. By a 3D preview you can check every step of the creation of the wing, 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. DESIGN AND ANALYSIS OF A MULTI-SECTION VARIABLE CAMBER WING. I use Rhino 3D which has a feature in the view menu to place a background bitmap, jpeg also works. I suggest that a comparative load test should be done between that CNC-ed rib and ordinarry build up rib from spruce sticks. You are on page 1 of 97. Regarding the design of the ribs themselves, as mentioned, 1 is a classic truss. If all is going well, just watch and enjoy the moment. I then met with the aircraft builder for his approval.                     Interchangeable mazes of increasing difficulty Be slow and careful to NOT run the bit into the material or hold-down clamps. 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. The higher end ones have a steep learning curve and take a while to be comfortable with. milling machine. I then  clicked the Reset button. We have in mind a large backlog of ideas that would be furthered by winning the PRS Standard 96-48-6 ShopBot . 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. Most of the time, it takes several tests and iterations to get it right. I have a background in fabricating Museum, Zoo and Nature Center exhibits. 8 years ago For the following results, it was assumed, the a maximum of 60% sag occurs between two ribs. Many tests were also made on parallel-chord specimens of truss and plywood forms in place of the actual ribs … Tooling Bits If it needs improving, return to Step 4, and go for Plan-C, or Plan-D, etc. 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). I'm building a flying wing right now too. They also sized it a bit to match the dimension given on the plans. Drawing, compatible with devCad Cam Pro 2. step by step approach. Winfoil is a an aeronautical computer aided design tool for designing, analysing and modifying model aircraft. :). Some very interesting results WILL occur and you really don’t want that experience. . 1 of wood, 2 of stamped metal. This is the interfaces that actually translates the g-code into movement by the router. 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. Faster tools. Sandpaper or foam blocks, (Things I need) 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. 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. 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. and go forth and back among the project wizard panels to retouch Things you need / Materials and equipment list:                     Mazes for more than one player The traditional approach is to make a jig, take hundreds of … Also that it is oriented correctly in the X and Y plane. Large scanner I have two Marske Flying wings that I want to build. 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. Plan B was run thru successfully.                     Picture frame mazes 7 years ago Good job. (http://www.cnccookbook.com/CCCNCGCodeCourse.htm) 2: Wing section, showing various degrees of the cover material sagging between ribs. Sad huh? I've noticed that many times we get buried in conventional thinking that is based on a theory nobody fully understands in aviation. Here we go, ignore this at your own peril. To me, this is amazing stuff, I used to hand cut all of these projects. West - Corona, CA Midwest - West Chicago, IL ---Ears - CNC machines are loud. (Tabs are small bits of the wood that hold all the various parts together. Thus a Maker Space has taken over my shop. 73994554-44848151-WING-SPAR-Presentation. Wally. The ribs form part of the boundary onto which the skins are attached, and support the skins and stiffeners against buckling. Sometimes it's better to just see if you can get something to work since everything is a great compromise in design anyway. The plywood was three thirty-seconds inch thick with mahogany faces and poplar core. Yeah!!! Then under “section plane” select generate section. Photography Skills Patience Cut the cardboard/plywood  larger than the project. (Computer Aided Manufacturing) Computer I have been also researching the design of my own and came up with a plan for a sporty looking, low wing, part 103. I never make that mistake. Two methodologies for the design of the wing rib are presented. No Cad skills are required! Designed specifically for holding wing ribs… your drawing printed or the cutting path ready to be imported in your CNC WING is a USA manufacturer using state-of-the-art materials and technology to deliver a tougher and longer lasting boat.. Then press the push pin through the hole in the angle and into the building board. 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. Riveting and spot welding are the The spar webs and caps are collectively referred to as the wing spar. longitudinal elements, Using DevWing you can create in a very simple way a ribbed 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.                     Cameos Location & Hours. I prepared to stop the cycle if it ran off in some bizarre direction. 2.5D Make sure that the piece you load on the machine is bigger than the project. I hope you can help me. X, Y and Z must be zeroed. settings, Spars, jigs and other I was given the sheet of blueprints (actually white zeroxed copies) to work from. Ribs definition and ---Breathing – All materials have some dust created during the cut. I then use the control point curve to trace the outline and then scale it to the right size in the "transform 2D" function. Kitfoxes have routed wood ribs but the factory does them by hand. At last the fun began. devWing are available, see the. It acts as a load distributor. 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. on Step 3, I would like to know more about how you faired the rib profile before you created the "G" code. 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 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. Seems obvious, doesn’t it? The ribs are then cut in pairs. How it works: just position the 90 degree aluminum angle next to the item you want to hold. I'd be curious to run a stress test to failure on this and a traditional built-up rib. Aircraft Structures II. 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. Wish I had done it earlier.) Title of Thesis: ABSTRACT. Regardless of the method, one wouldn’t want the highly rotating router bit or the router itself crashing into something hard and unyielding. The wing tip and root were then selected as the faces to remove, and what is left is the wing skin. Most plans come with a full-size drawing of the wing rib(s). Wing design can vary to provide certain desirable flight characteristics. Before any machinery is turned on, install the bit into the router you have. So, I went back the CAD and placed a number of tabs around each part. By that time I have lost the exact shape and the rib is worthless. About this time Mike introduced me to Instructables.com and I was hooked. (http://solsylva.com/cnc/vacuum.shtml). Web and truss are the main types rib. 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.
