Making Foam Wing Cores is relatively easy, using styrofoam. Im building my second plane in the garage now. The foam itself does the job of the diagonal members in holding the caps in place and absorbing shear forces in the rib. The most recent recommendation for foam that I have found: Blue Styrene: Dow Chemical Co. This is the first video in what will be an amazing build series, and [Peter] hopes to get this thing up in the air by September. Specifications we want to look at are as follows: Wingspan 36ft/11m Wing Area 70sq ft/6.5m^2 Empty weight 155lb/70kg The guys not rich, that only makes it worse stop leeching off your parents dude. I've actually poured the two-part expandable urethane foam between bulkheads on a keel structure, let it expand, then sanded it back down to the bulkheads, making a rough shape for a plug very quickly. @jamesqf; No, it isn't. He has decided not to release the plans as the plane is not a good performer due to being higher weight versus his intended results. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Was Galileo expecting to see so many stars? With a two-place ultralight, you can take a passenger along for the ride. Peters device may be unusual in that it could be reusable if he succeeds in flying it more than once. You can also shape parts such as a complete fuselage out of foam, then cover it with wood and/or fiberglass, and go a step further, to produce a finely-finished plug, from which you can then make molds. (depending on options) Gross weight: 725 lbs. The Phantom x1 was introduced in 1982 as a single-engine tractor configuration single-seat, high wing and tricycle gear ultralight aircraft. Or, if you take proper safety precautions, you can use a solvent, such as gasoline or acetone to melt the foam out of the inside. Suspension be carefulit melts when it becomes hotdon.t use styrole or styrene or however it is called regarding what chemical stage of priduction is wuoted. Richard is spot on! Foam Fuselages, Cowlings, and other parts can be made using at least three different methods. his airpkane flys, yesit simply shows that we all are restricted without any real reason but that Governemnets hate us to fly, they all fear terrorismit started with ww1anyone can build an airplane, it,s actually cheaper amd easier to do than a good sailing yacht( i tried both, and gave upwhat for? Making Foam Wing Cores is relatively easy, using styrofoam. Japan hosts a Japan International Birdman Rally over Lake Biwa every year where anyone can build a man-carrying ultralight and fly it, albeit once, off a dock for distance and entertainment value. and those control by law what i do and i have to pay them? Think about that the next time someone brings up the Part 107 drone certification. Its actually pretty easy and you don't need a vacuum or many tools. That's why, in addition to the structural strength it adds, foam wings and fuselages are always sheeted and/or fiberglassed, before any finishing work can be done. The Firestar is one of Kolb Aircraft's classic proven designs and has been in production since 1985. Peters plane will never get enough air time for fatigue to be an issue. So what *is* the Latin word for chocolate? Trike Wing Sails. It has the advantage of being very easy to sand and shape, cuts easily with a hot wire, and, in the lower densities ("white" and "blue") is fairly light. I used a four template setup: one template for the top center, one for the bottom center, one for the top tip, and one for the bottom tip. How can filling the empennage (aluminium tube) with Styrofoam stiffen it to avoid buckling as seen in Whingding ultralight? For initial design direction, I think a very good place to start is SparrowHawk. Waxing the Templates The mylar templates must be prepared before they can be used to make parts to ensure that they do not stick to the wing. foam cores are great for low stress constrcution amd no gasoline or other solvents coming thereimagine a gasoline tank is filled and some fuel trickles into the foam core, a death sentence! You do realise that familiy relations work very differently in different parts of the world, right? This requires quite a bit of time and work, but the finished wing is very light and has very good performance characteristics. Phone 509.682.4359 and visit northwing.com The hot wire follows along the template edge and cuts out the wing. As previously mentioned, under these rules, you must register your aircraft and have a current airworthiness certificate issued by an FAA inspector. and yes, the old specialistsin the EU clubs who have piwer over homebuilders use 50 yrs old wire cutting styrofoam techniques! and yes, asking for money bcs he is broke and wants to fly is low! All these characteristics combine to give an aerodynamically clean wing with a 12-to-1 glide ratio. You could cut the control surface out, then remove some leading edge material and replace it with balsa. The landing gear consists of a one piece prefab aluminum slab made from 1/2 x 4 2024-T351 alloy. middle ages! Tests are invaluable. A six foot chord and a 30 foot span provides for lift at 24 mph (14 with flaps down) and low drag co-efficient at the maximum level flight speed of 64 MPH. The maximum you can get is one atmosphere, which is roughly 1 bar, right? Go look up the Skypup Ultralight a design from the early 80s that used douglas fir or spruce cap strips and dow foam in between them. I've sheeted a lot of RC Airplane wings over the. The spindles are pre-welded and drilled for easy installation. Visit, Not the answer you're looking for? The problem with NACA foil designs is that they are not designed for a maximum speed of 64 MPH and a minimum flight speed of 24 mph. The first step in this process is to cover them with a release wax. 6/3/2022 $800.00. I never try a new process, such as paint, etc., on a major project. Sometimes, depending on the layup schedule, scoring the bottom surface of the wing might be required.Sand Hinge Line I used a foam sanding block to create the space for negative aileron deflection. With the Hi-Temp release wax I used, I waxed on, let dry for about 30-60 seconds, then buffed off. The relevant calculations have already been done, and [Peter] is already flying an RC scale model of this craft. is supplied as granular pellets saturated with a blowing agent typically pentane that is expanded into a mold with heat (the heat volatilizes the agent and the little beds puff like popcorn). Next, I made a partial layup in a mold for a vertical fin, and tested it there. Im building my first light sport aircraft and its one step above an ultralight and I wanted to have high back country bush stol capabilities and I would like to know if I should incorporate flaps with my ailerons or should I just run with flapperons what would be the advantages not knowing and at the risk of sounding stupid. it dissolves like sugar in that stuff as sugar does in water, second: foam cores more and more become an issue when you search around for delamination, not bcs styrole gasses out forever, but ncs the designers are undereducated and don,t calculate the local stresses on the binding areasthat simple! Why do we kill some animals but not others? Pretty cool project and hope he survives the test flights :D, (I accidentally clicked report, sorry, I hope your post isnt removed). , Hmm, does any humongous, only slightly heavier than air, craft with slightly negative buoyancy in air, but also with an aerodynamic lift, pass as an ultralight, or the regulations correctly specify mass instead of weight? A second seat is added behind the pilot. I recently saw a 2009 GT 400 for sale with 96 hrs on airframe. And than you just spray it? On that graph, it shows habitual use at 10% ultimate strength basically never fails, and thats his plan. Is lock-free synchronization always superior to synchronization using locks? It's composed of once-living but now empty cells, with cell walls of cellulose & lignin. Four axis CNC milling (Comment Policy). You can use Value XPS to fold airfoil shapes by adding a layer of tape to support the leading edge curve during bending. VACUUM! I am in the process of design of an ultralight plane for which I only have some of the skills needed. Custom cut foam core prices $20.00 and up Great job Peter. Other countries do this too with the first I believe having been done in the UK in 1971. Are ribs not supposed to be made of rigid, strong, woody and light material i.e pine,balsa etc.? Loadlifters Panel Loader: 3/4 inch webbing and ladder locks Ultralight: 1.2mm Spectra line and Lineloc tensioners. its nice, like the idea of a slow electric foam plane. we already have 50%+ on firts flight failures! This ultralight originally debuted in 1995, was discontinued for a while, and has since made a return with the Jordan Lake Aero company. Poplar, however, is ultimately stronger and available at his local home improvement store, even though it does weigh a bit more. Here's what this simple wire tool would look like. the EU basically outlawed anything that is jot an Experimental amd most other countries world wide imply military control on aviationbcs drug and gun dealers use any old gum airplane found in the woods or somewhere with lost certification amd such and still fy for years with them and transport their goods! I would rather not change a design that seems to work well but I could use some help in designing a spar or spar system that will support the wing/aircraft combintion. Carefully peel away the breather cloth, peel ply, and mylars, any you are left with your composite wing! TAKE 5% OFF these prices + FREE Wing Shipping if purchased in December! Leave the panels on the ground, interested love to fly south with birds lol. I could be wrong, but I dont believe anyone has gotten seriously hurt flying these contraptions. How do wing ribs withstand lateral lift force? The materials are birch plywood (3 ply) for the web and Sitka spruce for the caps. Scratch build micro size 24 wingspan super fast and stable foamie flying wing. I have also had the privilege of talking with a number of modelers and taking bits and pieces from each of them to come up with the following way that I . crazy! Parallel struts and x-wires provide the wings with their support. The airfoil above operates well in the range between 24 and 64 MPH according to the NASA Foilsim program and Aeval software. The first design simply labeled "Whing Ding," was first flow in 1971. I know very well how important my wing is to my life. Apparently Joe doesnt do his homework before spouting off. What gives? I see no point in solar panels on board, I suppose you might be able to squeeze out 5 more mins in an hour flight? The function of the diagonal members (to carry shear loads) can be performed by 45 glass fabric on the surface of the rib. . This particular wing is intended for an Discus Launch Glider that meets F3k rules and requirements. So be VERY careful if you use this method. $17,800 ATF Light Soaring Trike with 200cc Minari engine - Solairus 16.8M Wing. But you succeeded! The wood rib has the primary compression and tension members in the capstrip, with the diagonals absorbing shear loads, converted to compression and tension loads along the legs of the truss. it.s still common practize in the EU homebuilt clubs that control the homebuilders under advice/ force by the authoritiesbcs they seem to tjink tjise old guys know their tradeyes, somehowseemingly on 1980 ies levelsbut take toms of money for controls Cheap, saves time. I used regular Krylon Indoor/Outdoor spray paint. Make sure all the layers are in the right order, then turn on the vacuum and set the pressure. This gives you repeatability, which makes sense for a complex project. Powered by Invision Community. This highly accurate machine can be used to cut anything that a hot wire can pass through safely. I left about 6-8 inches excess on both sides for the bag clips, which are used to seal the bag after the parts are inserted.Inserting Hose & Sealing Bag A small slit is cut into the side of the bag for the vacuum pump hose to be inserted. Then cut some lengths of yellow nyrod to fit, and epoxy these through the tube and into the elevator halves. Wipe off any excess epoxy and let it cure, then sand the surface smooth. If youre concerned about [Peter]s safety, hes also put up a GoFundMe page for a parachute. I would prefer an aerodynamic plane that can take me 200Ks with low fuel usage. I have 1 two place (for sale) and also 6 others. The FT hosts did the Redbull Flutag a few years back so powered flight seems like an obvious next step. Also, the "negatives" should be sanded as well, and be sure not to loose them. low wing, part 103. The foam is used to take small shearloads and support the primary structural element in absorbing tension and compression loads. no, there is a paragraph against it! The Wingspan is 38.5 inches. Foam on it's own is not structural. People thought epoxy was better due to leaking and delamination of older fiberglass techniques. In a composite structure, the foam serves the purpose of providing a shape, while the material that surrounds it serves the purpose of providing the strength. The wing won't hold any fuel - the 30 pounds of fuel is located at the center of gravity. Good luck and be safe [as possible]. 4 years ago Efficiency for instance is abysmal for these. I get the feeling that Richard has his head screwed on. ChengLInk liked ESP32 E-Paper Weather Display. There will be a handful of people touched by your videos that will become aviators and innovators because of you! Don't glue it to the stabilizer itself! I have seen all your videos and I think you got a great start of something fun I was wandering where you got your plans from and the name of the plane I was thinking of maybe trying to use the same plane but add a few more motors for vertical take off ? The outstanding new design winner from the 1982 EAA International Air Show earned that title with high scores for appearance, design, engineering, flying performance and portability. Foam Wing Construction Terry Boston SPA 698. surely very eko friendlyand millions of km of new copper cables for charging stationsall that is powered by fossile fuels for the engines, trucks and machinery to dig the ores, coal for processing amd so basically all a lie, not eko friendly at allat the contrary, as it doubles the need for ores and metals and fossile fuels for producing all that stuff, so combustion engines are lighter, need thereby less fuel at the emd amyways, don.t need extra mewly built faciluties and infrastructure and so onelectric propulsion is a lie! Bud Bennett has updated the log for Seismometer. Weight is a prime concern but drag is not. You must be aware that these solvents are highly combustible, and that the melting foam produces toxic fumes you must avoid, and that the melted foam itself is rather a nasty mess. it worksfoam is hood for low loads spread over wode areas, damping flutter and vibrations and insulation against temp. Is that after you have some wax? There are two options, single page with full plans and two page single wing, just flip the wing template for other side. his batteries free! The video (below) is unclear, but we can only hope [Peter] has read up on the strength of aircraft frames and the orientation of the grain of each structural member. Make sure to print at 100%. Useful load: 400-445 lbs. I have been thinking about ultralighs for years and now that Im retired I have time for my bucket list. If your aircrafts empty weight is over 254 pounds, you will be flying under GA Rules (Part 61 & 91). ) so what plqns do you need? Hes using foam insulation sheets for the body of the fuselage, reinforced with plywood and poplar struts. Then carefully cut out only the area occupied by the leading and trailing edges, leaving the control surface in place. You either are unwilling to help or don't know how to build the spars any more than I do. Thanks. However, ribs at the wing root of a removable wing sometimes have to carry half the lift load, for example in gliders. There a foam rib would be totally inadequate. If a law is new but its interpretation is vague, can the courts directly ask the drafters the intent and official interpretation of their law? So please be patient. This could be used for installing a wing socket for a joiner tube, or simply a channel to route servo wires through. Sign up for our newsletter and be in the know. You have contributed to experimental and ultralight aviation and advanced our pool of knowledge. not heat resistantwhen you park the bird in the Arizona sun and have a dark paintjob done, it basically evaporates inside and weakens! Use a high quality brush to get the smoothest finish. Im confused when, and onto what, you spray paint? Thank you for telling me to learn how to design the aluminum box to fit my needs - perhaps that is the most important thing your post said. on Introduction, good question. I used Lowes foam which was a cheaper alternative to rohacell foam. take care Is email scraping still a thing for spammers. This means laying out all the tools and materials you need, making strips of tape, laying out cloth, etc. so his constructions show that possibly anything can flybcs he builds in real size! The first was a plans built, two seat wood and fabric strut braced high wing with a converted Volkswagon (Revmaster). Looks great ! After the blanks are made, the wing templates can be aligned on them and the airfoil can be cut. If [Peter] can keep the weight down in other areas, poplar is an excellent choice due to cost and availability. I've built a number of models over the years with foam wings and stabs of all sizes from .25 Pylon racers to 43% models with 200cc gas burners. BE SAFE! Hes friends with Flite Test, and there he built an enormous RC cargo plane that could easily carry a small child aloft. Thread starter pilotnick12; Start date Sep 2, 2013; Tags design foam homebuilt ultralight ultralight design 1; 2; Next. Most are designed for speeds in excess of 200 mph and are inefficient at speeds below 70 mph. A strong and simple control horn can be made by threading a nylon aileron connector onto a 6-32 machine screw, then screwing it into the dowel. Yes,legally, any moron can jump in an ultralight and fly. [Peter Sripol] is something of a legend in the DIY RC aircraft crowd. the UK fights against it with stronger controls! [Peter]s going to fly this thing if you complain or concern troll or not, so donate a dollar for the parachute if yourethat concerned. If it passes static it will be strong enough. just another delusional heavy crap added to the bird! This can be accomplished with physical pressure on the sheeting/foam/sheeting "sandwich", or by vacuum bagging, which is the superior method. The hinges need to be cut on a bias, this is to align the fibers in the best possible way to create a hinge. In one afternoon, I cut foam wing cores, assembled the sheeting, and had this shape, which is a lot more precise, and less expensive. It looks like the fiberglass and aluminium are the worst in terms of fatigue problems.
