Thank you for the concern. PaulS1950, What type of insulation foam is used in these aircraft? The Phantom x1 was introduced in 1982 as a single-engine tractor configuration single-seat, high wing and tricycle gear ultralight aircraft. The wing will be fabric covered so the covering is not structural. The foam itself does the job of the diagonal members in holding the caps in place and absorbing shear forces in the rib. idiotic! Years ago, I spoke to a professional boat builder about using insulation foam (specifically Styrofoam and no-name clones of such) and he advised strongly against it. take care I am in the process of design of an ultralight plane for which I only have some of the skills needed. With all the brands and models on the market, it can be hard to sift through the noise and zero in on the best options for your ultralight purchase. Suspension Have there been any floats/wheel combo added to a ultra-lite? @jamesqf; No, it isn't. He wants to make a lighter, STOL airplane that he plans on being performance-oriented. VACUUM! Be careful not to add too much spray paint, because it will add weight to the finished wing. Here's what this simple wire tool would look like. Connect and share knowledge within a single location that is structured and easy to search. 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. A wood structure as precise could have been built, but the time factor was not something I was not happy about, so I went with foam. However, ribs at the wing root of a removable wing sometimes have to carry half the lift load, for example in gliders. I have seen several YouTube videos of ultralights and even HPAs (Human Powered Aircraft) that use foam as the ribs of their wings. This is the hardest part, dont believe me? Conyers, GA 30094 USA. old hippie methods? $17.33. As far as anyone in Germany or Switzerland having built even one wing that is designed to operate in the speed range that mine will and although they do have some microlight aircraft their aircraft do not meet the specs for the USA FAR 103 ultralight specifications for weight or speed range. White bead foam can only handle a couple bars before it is crushed. The first was a plans built, two seat wood and fabric strut braced high wing with a converted Volkswagon (Revmaster). Here is a commercial site (I have no connection to this) about the agents used in sheet XPS: http://bit.ly/2vxr6p2, the problem is not the pentane , extruded styrofoam is simply not gasoline resistant! (Hence the 2000->200 test). Then drill a couple of small (1/8th inch) holes from the front (leading edge) side of the tube, through the tube and into the stabilizer about an inch or more. Again, good luck [Peter], please be careful, Download the flight simulator X-Plane, there is a plane builder, design your plane, fly it. Finally, you would probably tack glue the surface back onto the wing, and sand to the proper shape. Because its going to be incorporated into a house there are some pretty strict standards about reactivity, VOC and outgassing no bueno if it makes people sick both in the factory or at home, or causes the shower stall to come apart. (The tape can be removed when the foam is glued in place.) Its made out of insulation foam. Then develop an aluminum box to take all the loads and the torsion, Then check for flutter, then see if it will fit into 9inch limitation. Contact Brendan@usysinc.com, Can you describe how you painting the wing? Both Upper and lower wing are removed as well as rear horizontal stabilizer. Built in the USA with refined design, quality materials, and supported by a worldwide dealer network. The construction of [Peter]s ultralight will be a highly refined version of this. Foam has some qualities you need to be aware of, as far as how it reacts with adhesives and solvents. When considering your options, rank the merits of each aircraft and compare them using the Ultralight News handy 10-point system for rating ultralight aircraft. Expect an inexpensive, easy to build and fun to fly aircraft. As with any, guy builds an airplane in his basement story, there must be a significant amount of time dedicated to the legality, practicality, and engineering of said plane. I will use Junker style ailerons and ungapped hinged simple flaps. 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! 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 kevlar will create a very nice lightweight hinge in the completed wing, but its also very strong. Then develop an aluminum box to take all the loads and the torsion, Then check for flutter, then see if it will fit into 9inch limitation. Once done, gear doors were roughly outlined, then traced and cleaned up, using gridded vellum. The machine uses servos paired with high resolution encoders to give accurate and repeatable results. I use a 1/4 inch carbon fiber tube for most of mine, but you could use a rigid wire, or other material, depending on the size of the elevator assembly. I would suggest you start with an NACA airfoil configuration http://www.allstar.faero/wing31.htm . Prepare Templates Paper templates are made in all the shapes of the fabric that need to be cut out, card stock or index makes for the best tracing paper.Trace Templates on the Fabric Tracing on the fiberglass and kevlar is pretty straight foreword. Standard features include an open cockpit, removable wings, steerable tail wheel, 4 point safety harness, fuel tank, factory welded fuselage and tail. The basic process is to produce templates first, (usually a "root" and "tip" template) then use the electrically-heated hot wire to cut the basic wing shape out of the foam. middle ages! CA and polyester resin will also melt styrofoam, and should not be used. 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. he did a great job for someone with such lack of information/knowledgei even got my firts ideas from himnow 2 yrs later and hundreds of hours of research i know bettersorry.the best stuff he explains is the balance! Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. we in construction learn this in tje second semester! Great work so far. The Gull may be light on weight, but it delivers on performance with smooth flight and phenomenal fuel economy. The airfoil above operates well in the range between 24 and 64 MPH according to the NASA Foilsim program and Aeval software. Cutting and Storing Fabric I cut all the straight lines with an exacto, some of the curves too. The finished weight on this set of wings is 129.9 grams. Styrofoam 2 lbs/ft 0.2 lbs/ft density. Wings are hung to the fuselage with a single strut. Phone 509.682.4359 and visit northwing.com the FAA grounded him bcs he showed his private parts on a vid( by accident?dunno..who cares..). Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? Tests are invaluable. Very stable for a wing, with. 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. You need to determine the local loads and then decide if foam alone will be sufficient. Richard is spot on! Ultralight Foam Camping Mat Folding Beach Tent Picnic Mat Sleeping Pad. The epoxy boards would ding and dent to hell and back if you just looked at them. How would I go about calculating the strength of a wooden spar that is 5 inches high, has a web thickness of 1/8" and a top and bottom cap of 1.5" x .75"? There will be a handful of people touched by your videos that will become aviators and innovators because of you! bending wings made from willow and ash! The foam is weatherproof, easy to form, and less rigid than Depron, but more flexible. https://www.boatdesign.net/attachments/fatigue2-jpg.8544/. The seller went from b7000 down to 6000 dollars . Sign up for our newsletter and be in the know. (Use the appropriate type of wire for your power requirements, and use caution.). Pegasus H-3 The H-3 Pegasus is a low-wing, open cockpit monoplane by noted lightweight sportplane designer Bert Howland. Can "a drone" damage the wing of "an aeroplane" to the extent it actually threatens its ability to fly? Making its debut at the Midwest LSA Expo Sept. 10-12, 2020, was Aeromarine's new Part 103 ultralight aircraft, the Merlin Lite. Other countries do this too with the first I believe having been done in the UK in 1971. It is also easily fiberglassed, using either polyester resin or epoxy. Where could I find wing templates for a wing like the airfish 2? If you intend to fly with a passenger, you are required to earn a recreational pilot certificate. This particular wing is intended for an Discus Launch Glider that meets F3k rules and requirements. This highly accurate machine can be used to cut anything that a hot wire can pass through safely. Like to hear about 1 and 2 seatersI,m old 90 and was an IFR rating all in single engines. Receive coupons and special promotions! Also, the "negatives" should be sanded as well, and be sure not to loose them. That pentane may be what your friend was referring to its either been replaced in most applications or is in the process of going there. I used a gravity fed system, which pulls the wire through the wider chord of the wing slightly faster than at the tip. Then design the Ailerons that will take control of the aircraft with the fuel moving outward to inward in knowing where the center of gravity of your aircraft is fully loaded. You do realise that familiy relations work very differently in different parts of the world, right? and so onand so on I believe that it would be lighter to use the leading edge "D" box spar and the rear spar that the flaps will hinge on as the load elements and attach the wing to the top of the fusalage and with struts at some length of the span for twist prevention and longtitudinal stability. This isnt a comment but a question. North Wing manufactures high quality, weight shift control Light Sport Aircraft, Ultralight Trikes, Trike Wings, and Hang Gliders that are fun to fly. 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. For slow-flying ultralights, how would a delta wing compare to a biplane layout of equal wing area? Make sure you measure out your epoxy precisely and mix it thoroughly to ensure the strongest finished structure. its normal that many people tell bad things, if someone new starts such a project. This ultralight originally debuted in 1995, was discontinued for a while, and has since made a return with the Jordan Lake Aero company. I ordered fabric from ACP composites: http://www.acpsales.com/home.html. Torsion-free virtually free-by-cyclic groups. Peters device may be unusual in that it could be reusable if he succeeds in flying it more than once. but with airplanes itls a daily treat? This part gets kind of tricky, I used mostly exacto, but I found I wanted scissors for a couple of things. I use a silver sharpie on my carbon fiber and it works okay for marking things out. I will close by pointing out that two bicycle mechanics figured out how to fly well by understanding aerodynamics were king while simultaneously beating out a huge government funded push to create a controllable airplane headed up by a man with the familiar name Langley who insisted horsepower was what was needed. That is produced by phantom aeronautics of Three Rivers Michigan and is available in kit form. The foam is used to take small shearloads and support the primary structural element in absorbing tension and compression loads. It looks like the fiberglass and aluminium are the worst in terms of fatigue problems. Folding Camping beach Waterproof Sleeping Pad Mattress. The MX II Sprint was built with the new pilot in mind and is one of the easiest two place ultralights to assemble and learn to fly. And with all of the modern materials and so much work being done by so many experimental builders over the years there is a wealth of information out there. The wings are also covered with doped fabric. It breaks.

The difference is that styrofoam those stuck-together beads that everyones seen in coolers etc. crazy! I also cut out the doors, and did some testing to decide how we would hinge them, and how we would operate them. Ultralight: Wings with no lumbar pad, 1/4 inch EVA foam. The purple "dot' in the image is another item you may want to add, which is a hardwood dowel, epoxied into the leading edge of the control surface, which will serve as a mounting for a control horn. Go. So far, everything is not as sketchy as it could be. My plane will have a 30 foot one piece high wing with a chord of 6 feet and maximum thickness of 9 inches. 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. Hes friends with Flite Test, and there he built an enormous RC cargo plane that could easily carry a small child aloft. It calculates realistic values depending on the geometry, airfoil some hidden repirts can be foundsimply designers seem not to have any clue or education about stress loads in a stringerand wings or fusellages are basically complex stringersso a foam core wrapped in a hogh strength skin only good for srtess but no compression has a big flawthe foam core is too weak on the outer regionsbut everyone ignores thisso others laminate two wing skins, embedd a stringer out pf wood but better aluminium and glue it all togetehras long as the aluminium is not tired of chnaging stress loads( and all aluminium tires out.) I used regular Krylon Indoor/Outdoor spray paint. and insert them into the slot you've made. his motors were free! Only a few make it close to the opposite end of the lake without a dunking. Complete airframe kit cost: $6,995. on Introduction, Reply Just remember that with a two-place aircraft, you will be flying under GA Rules (Part 61 & 91). What are the penaltys if you was to get caught flying a light sport aircraft with a passenger with out any licensing at all , i live in alaska, After seeing the U-tube video, I now have to have one. The answer depends on the wing loading of the aircraft. No, X86 Single-Board Computer! Here's how I do it: Cut a slot for the joiner tube, and carefully tack glue it only to the elevator halves. COMING SOON! Cutting Wing Core Blanks Wing Core Blanks must be cut from foam. The process for building the stabilizers is almost exactly the same as building a wing, except its smaller and uses a symmetrical airfoil shape. Don't glue it to the stabilizer itself! A few years ago, [Peter] built a gigantic remote-controlled cargo planeout of what is basically foam board and a few aluminum tubes. The layup above was trimmed a bit, then some temporary formers were CA'd into it, so we could verify the retract operation. The spindles are pre-welded and drilled for easy installation. Thanks, that graph is very interesting and sobering. The EZ Lam Epoxy I used required a 2:1 mixing ratio.Rolling Epoxy Spread the epoxy evenly over the fiberglass, Carbon, and Kevlar parts as carefully as possible. And than you just spray it? As previously mentioned, under these rules, you must register your aircraft and have a current airworthiness certificate issued by an FAA inspector. Sign up for a new account in our community. ( i.m so envious! [Peter Sripol] is something of a legend in the DIY RC aircraft crowd. You could cut the control surface out, then remove some leading edge material and replace it with balsa. if you can.t even that then don,t even start! Is email scraping still a thing for spammers. I raise an eyebrow at most of these entries. If your aircrafts empty weight is over 254 pounds, you will be flying under GA Rules (Part 61 & 91). I really like building my own stuff! Kolb offers more safety, fun and performance in 254 pounds than any other manufacturer. With a two-place ultralight, you can take a passenger along for the ride. 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. Its my understanding that the weight limits apply to the deflated balloon or blimp. Hotwire to shape the foam into aerodynamic shapes is easy and repeatable. Working Time I used 30 minute epoxy, which means the epoxy has a 30 minute working time from when you mix it to when your part should be under vacuum. I used Lowe's foam which was a cheaper alternative to rohacell foam. Training for pilots operating under FAR Part 103 is self-regulated and you need not obtain an FAA pilot certification. Bob. it.s outlawed since 2019 almost everywhere) if you use foamcores you need to know the stressload distripution running thourgh the airfoil area, and most let that outand so the stresses on the binding surfaces are too much and the foam comes looseor it.s simply not propable of taking changin intervall loadslike many poor aluminium alloys..they stress out pver time and get crackswood holds up the longest, uless it starts to get moldy/ rotten) This means laying out all the tools and materials you need, making strips of tape, laying out cloth, etc. A second seat is added behind the pilot. When I install these on the actual model, all the guesswork will be done, and we know they'll work right. Panel loader: modular full wrap-around 3/8 EVA foam hipbelt and a double pull 1 inch buckle. For the Lowes Foam I used, I pulled about 10 bars of pressure. most make one mistake, when they add a stress loaded part instead of an unstressed part( replacing fabric skin for plywood) they still fuck in hundreds of diagonal strutsAND add the fabric on topand so onbcs they have no education amd knowledge about whta they are doing, just rules of thump Foam Fuselages, Cowlings, and other parts can be made using at least three different methods. Why were most of the first-generation-Learjet wing mods never approved for the Learjet 23? Then load it up with 200 lbs and start shaking. Copyright ScienceForums.Net I didnt realize that it can get so bad. The maximum approved gross weight for a two-place ultralight is 1,320 pounds. Well return with full functionality soon. cant believe I left it out. Essentially, you use the foam as a scaffold and place stiffer material where the sticks on the wooden rib go. Need several wings manufactured. use PU, epoxy, wood and well approved metalsforget styrofoam! Next Last. It was the first fully enclosed ultralight on the market and has become a time-honored classic. $39.58. Once you've built the horizontal stabilizer, use the method above to create the "built-in" control surfaces. Thread starter pilotnick12; Start date Sep 2, 2013; Tags design foam homebuilt ultralight ultralight design 1; 2; Next. Should I include the MIT licence of a library which I use from a CDN? try to build a mold and spray PU foam of needed desity/stress strength etc into itoff course you jeed some foul or wax to take it outsome build that wayor you foam a block and cut all outand so onit.s still primitive amd many companies just before covid pisted NEW videos about their crude building processes! Even given that there was an abundance of information and materials to work with since flight first began in America, you are still a pioneer. So be VERY careful if you use this method. $17,800 ATF Light Soaring Trike with 200cc Minari engine - Solairus 16.8M Wing. He was working as a waiter and lives in his parents basement. Did you make this project? Two flying and and 4 to putter with. These need to be sanded away so the wings are nice and smooth. Here's how they're done, in a vacuum bagged layup. One advantage of making foam wings is that it's easy to be both fast and precise. Next, any interior cutouts and/or installations are done in the foam, before it is sheeted and/or fiberglassed. There are motors out there. and I ordered my bagging materials from CST: Ill add that, Thanks Charlie. The Long-Ez and variants, the KR-2, Quickie, Velocity, and many more. The design of this aircraft is an electric, twin-engine biplane. This greatly helps to reduce the finished weight of the part.Placing Cores After the epoxy is evenly spread, the foam cores are placed on the bottom of the wing, then I flip the top mylar over on-top of the foam core and carefully place in the vacuum bag. The Sling 2 Kit is identical to the Sling LSA and upholds the same performance qualities as its S-LSA ASTM-standard sister aircaft. (Shown in yellow above) Now you have a light, rigid and vibration resistant connector that will maintain elevator alignment! Peter obviously learned a lot about aeronautics through the construction and flying of RC planes, a luxury that the Wright Brothers didnt have. 1998-2023 PilotMall.com All rights reserved. This is slow for a Cessna, but just about right for the gigantic remote-controlled planes [Peter] has already built. Rock Paper Scissors Using Tinkercad Circuits and Arduino, Punchy the MECH & the Autonomous Fight Club. Brand F.B. The first step in this process is to cover them with a release wax. I bent the aileron open to about 70 degrees then ran the sanding block up and down the gap until I created the appropriate amount of space.Sand Leading Edge Seam Depending on how well you lined up your seam, the leading edge will most likely need a little sanding to make it nice and smooth. The pressure depends mostly on the foam core that you use. 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. First, finish gluing the joiner directly to the stabilizer halves with a little epoxy. The top pair of images is the inside, and the bottom pair is the outside. , 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? I sprayed down the 1" carbon fiber bias cut strips I was using with 3M then carefully wrapped them onto the leading edge. There is a certain mystique and allure about ultralight aircraft. 9 years ago Sometimes you'll have a need to cut a channel, or other hole in your core, span-wise. Some foams can withstand more pressure than others. . There are a lot of types, but extruded polystyrene (XPS) is common in the US. The relevant calculations have already been done, and [Peter] is already flying an RC scale model of this craft. Some are serious contenders sponsored by universities and clubs and some are little more than costumes put on by individuals, but all eventually end up in the lake to great applause by the audience. Youre second design looks much improved though you need to redesign the gear and tweak the weights and balances. How do you apply 10 bar pressure using vacuum? Consequently, the loads on the single structural members are low, too, so you can get away with foam-only ribs. The kit allows the builder a bit more freedom . 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. Then, work the hinge until the aileron moves freely. The leading edges of aircraft wings have to meet a very demanding set of characteristics. I watched all of the videos available of both projects. $18.60. Apply epoxy to the exposed foam surfaces in the wing only, (You don't want to glue the two pieces of balsa to each other!) I havent tried it personally, but I have heard that things can sometimes stick.Spray Painting This is the fun part of the mylar prep, spraying on the colors of your finished airplane. videos on youtube, interested in knowing approximate weight and range you got with that setup. Pilots looking for the best bang for their buck on a tried and true ultralight will be delighted with the Jordan Lake Air-Bike 103. Ultralight Foam Camping Moisture Proof Picnic Mat Folding Tent Sleeping Pad 2023. What does a search warrant actually look like? 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. Weight is a prime concern but drag is not. The options for the Airbike include various engines, folding wings brakes, trim, wheel pants, wing tips bucket seat, extra fuel, plus various quick build and assembly packages. Now, cut the two required pieces of balsa. Yes, this ultralight is constructed out of insulation foam, but you can think of that as just a skin. Make sure to print at 100%. February 20, 2012 in Engineering. Tesla now needs Uranium and powerplants to feed his cars, that.s. After the epoxy is evenly spread and has thoroughly impregnated the fabric, I lay out paper towels over it and roll out any excess epoxy. It will take-off at about 25 - 27 mph and have a maximum straight level speed of 63 - 64 mph. I'm starting this process with the wing spar. Though it may be adequate, Im not technically an engineer, This isnt the first time someone from the Flite Test family has done foam board manned flight. If it passes static it will be strong enough. proven that combustion engines need about 200-250g of fuel per HP /hour.netto! If I use wood "I" beams and protect them from UV and moisture they will last for hundreds of years and be lighter than an aluminum box. 4 years ago Great job Peter. I never try a new process, such as paint, etc., on a major project. 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! Cutting Templates I cut my airfoil templates using my CNC machine. 1 of 2 Go to page. This foam and wood build will be wrapped with carbon fiber and fiberglass sheet, epoxied, and hopefully painted with flames on the side. Very slick, and much easier to maintain precise fit and alignment. Cheap, saves time. Sorry for my bad english. There are several commercial devices made for cutting foam wing cores and other parts. Do you have any data for wood? This ensures that everything lines up when you place the foam cores on the mylars during the bagging process. Painting PVA After the mylars have been waxed, a thin layer of PVA is added to help ensure a nice mold release. he prooves that it.s easy and simpkethe lifespan of his plane is short anyways, he built anotherone laterunderpowered again bcs electric propulsion is a lie! Use a high quality brush to get the smoothest finish. what elsei want 2 ums 16 hp radials for free too, each is 2,8-3,2kand i want the same rules for ULs where i live or a free visa to fly in the US tooyes.we all can wantbut realuty sucks! 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 ? If you just want to make one part, and don't care about repeatability, you may choose the "lost mold" method. He is very overt about his Thai background and the restaurant his family owns. This tandem style seating configuration minimizes the difference in center of gravity when flying alone vs with a passenger. You need to be a member in order to leave a comment. Its important to let the spray paint completely dry for a day before bagging your wings. I would only recommend this project to an more advanced builder. itls harmful to the environment, just when you consider charging losses of 20% every time sou use any kind of batterie, production and twice the weight all he proves is that it can be donewhen you use 2 cheap RC 160 ccm engines they hold on for 50 hrs u til they need a rebuild amd then you have 16-20 hp easilyand not 5-8his one had merely 5 kw! What is a good price ? I have been thinking about ultralighs for years and now that Im retired I have time for my bucket list. his batteries free! Foam Wing Construction Terry Boston SPA 698. By the time I got to this stage, it was no experiment. Where I must fly there is only woodland or sea, and the sea has crocs, so reliability is everything. and he shows what is possible against the maistream.the rest is kinda dangerous.
