Question Pretty cool project and hope he survives the test flights :D, (I accidentally clicked report, sorry, I hope your post isnt removed). North Wing manufactures high quality, weight shift control Light Sport Aircraft, Ultralight Trikes, Trike Wings, and Hang Gliders that are fun to fly. An ultralight is not required to have an airworthiness certification, and pilots of ultralights are not required to pass any tests of aeronautical knowledge or hold a medical certificate. Specifications we want to look at are as follows: Wingspan 36ft/11m Wing Area 70sq ft/6.5m^2 Empty weight 155lb/70kg Still very active. The hot wire follows along the template edge and cuts out the wing. The Firestar is one of Kolb Aircrafts classic proven designs and has been in production since 1985. Looks great ! Using 600 - 650 gross weight and a 6 g load factor will wood or wood / foam sandwhich work in this construction. In this work, we synthesized ultralight 3D structural CNTs/porous carbon foam composites (CNTs-CFs) using a simple chemical impregnation and pyrolysis method, in which in-situ growth carbon nanotubes with different morphologies and loaded with metal nanoparticles (Co, Co 9 S 8, Co 0.7 Fe 0.3 and FeC 3). minimal mufflersso , tell me anyone if his electric propulsion is reasonable or safeone RC engine with low service life costs less than 1k, expensive ones cost 2no extra weight..and as his batteries just hold for 15 minutes or suchsince ww1 its. I'm starting this process with the wing spar. It can handle almost all types of flying but really excels as a performance handling, cross-country aircraft with its completely harmonized controls and 800+ nm range. If [Peter] can keep the weight down in other areas, poplar is an excellent choice due to cost and availability. The wing will be fabric covered so the covering is not structural. Need several wings manufactured. As previously mentioned, under these rules, you must register your aircraft and have a current airworthiness certificate issued by an FAA inspector. Well return with full functionality soon. Bob. Learn more about Stack Overflow the company, and our products. Some ultralights have a foam rib core with an aluminum cap strip bonded to the edges to do this. TAKE 5% OFF these prices + FREE Wing Shipping if purchased in December! Maybe as cheap as 500 dollars. , 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? One of these, which comes very highly recommended by several experienced builders, is Carnauba 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. Great work so far. Make sure that it will takr the landing wheel loading and cycles you need if you have wheels. Richard is spot on! others are addicted to carbon laminateswhy? Peters plane will never get enough air time for fatigue to be an issue. 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! and he shows what is possible against the maistream.the rest is kinda dangerous. White bead foam can only handle a couple bars before it is crushed. Built in the USA with refined design, quality materials, and supported by a worldwide dealer network. COMING SOON! looking for 2 seat preferably. The airfoil above operates well in the range between 24 and 64 MPH according to the NASA Foilsim program and Aeval software. The H-3 is not an ultralight vehicle as defined in FAR Part 103. The foam itself does the job of the diagonal members in holding the caps in place and absorbing shear forces in the rib. 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. The cola in the can is doing the same thing as the foam in the wing; it makes sure that the empennage cannot dent (maybe cannot is an overstatement . I was under the impression from one of his other videos that he is working in the restaurant that his parents own. Hotwire to shape the foam into aerodynamic shapes is easy and repeatable. To fly under FAA Ultralight Rules (FAR Part 103), the single place aircraft must be used for recreational flights and have an empty weight of less than 254 pounds. 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. sorrytoo heavy! The difference is that styrofoam those stuck-together beads that everyones seen in coolers etc. Insulation foam covered in fiberglass is very popular with many home built aircraft. For initial design direction, I think a very good place to start is SparrowHawk. But you succeeded! 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. proven that combustion engines need about 200-250g of fuel per HP /hour.netto! no, we are compkaining on the qck of sophistication amd mass overpraise which is not rectified by the results and methods! 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. Why do we kill some animals but not others? I will use Junker style ailerons and ungapped hinged simple flaps. Don't glue it to the stabilizer itself! 4.00 x 6 Azuza wheels and wheelbarrow tires finish out the assembly and brakes can be adapted with little effort. Seeing that your parents are both supportive of your dreams enough so as to put their fears for your life and safety aside and allow you to experiment with life, Im guessing that they are also dreamers who have built their dreams into realities. Thanks, 9 years ago 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. First, finish gluing the joiner directly to the stabilizer halves with a little epoxy. A really quick and simple way to build an actual airfoil for an RC airplane wing. 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. Just remember that with a two-place aircraft, you will be flying under GA Rules (Part 61 & 91). Monnett Moni Ultralight Airplanes Hagerstown, MD 21740 USA. No, X86 Single-Board Computer! Laptop Motherboard? 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. Finally, I incorporated it into the "Eliminator 2" vertical fin, and on the other wing and tail parts. it burns like gas on fires! Do you paint onto the wing directly? Expect an inexpensive, easy to build and fun to fly aircraft. Where could I find wing templates for a wing like the airfish 2? Styrofoam 2 lbs/ft 0.2 lbs/ft density. It calculates realistic values depending on the geometry, airfoil But if it fails, expect to see the (hopefully not too) tragic results to appear on the Discovery and/or National Geographic Channel in yet another of their ubiquitous found footage on the Web programs that make up Soooo much of their content these days (the lazy bastards). It is with aluminum frame, with the same foam core fiberglassed flying surfaces. 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. The second category of ultralight aircraft is two place or two seaters. For slow-flying ultralights, how would a delta wing compare to a biplane layout of equal wing area? I haven't calculated the precise wing loading but its more than low enough for this airplane.I haven't taken them for their maiden flight yet, I will have to update this later. and yes, asking for money bcs he is broke and wants to fly is low! 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. This ensures that everything lines up when you place the foam cores on the mylars during the bagging process. Loadlifters Panel Loader: 3/4 inch webbing and ladder locks Ultralight: 1.2mm Spectra line and Lineloc tensioners. Im a huge fan of nothing beats aerodynamics though the macho idea of nothing beats horsepower seems to have come home to roost. The airplane has a 22-foot wingspan, is 17 feet long, and is powered by batteries. http://1.bp.blogspot.com/_w2EkcRcsSqA/S7EvXGMFk4I/AAAAAAAAAN0/tTiFEmGAY4c/s1600/fatigue+strength+composites.JPG. I am in the process of design of an ultralight plane for which I only have some of the skills needed. on Introduction, good question. Here's a closeup view of the layup used to create the skin hinges. Here's how they're done, in a vacuum bagged layup. 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. ask a civil ingenieer abozt construction, they will laugh at the idiocies done at airpkanes amd carsdon.t ask architects, thise are just designersartists! 1-place Trike Retrofit Kits. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Ultralight Foam Camping Mat Folding Beach Tent Picnic Mat Sleeping Pad. I know there are balloons that make the unpowered weight limit (155 pound), of both cloudhopper and basket designs; dunno if there are powered blimps making the 254-pound limit, but it should be possible. These test parts are approximately 4 inches square. if you can.t even that then don,t even start! Pictured above is 2004 EAA Sun-N-Fun Of course the aircraft are composite so they composed of different foams for different parts. Lengthwise reinforcements using glass rovings on the top and bottom side of the rib improve its bending strength. The foam is used to take small shearloads and support the primary structural element in absorbing tension and compression loads. I was wondering if you could make an entire structure (bulkheads, stringers etc.) 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 ? Leave the panels on the ground, interested love to fly south with birds lol. Sponsored. The order of the layers placed in the bagBAG Breather Cloth Peel Ply Mylar Fiberglass Carbon Parts Foam Core Carbon Parts/Kevlar Hinge Fiberglass Mylar Peel Ply Breather ClothBAG This is where the table would be. Such a simple plane. 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. 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. The design of this aircraft is an electric, twin-engine biplane. Fund your own parachute. and it is mot good for pressure loads as a thin laminateand delamination recently became an issue on airliners too! :nervous: I'm trying to design this plane with modern material technologies to make it lighter and, if possible, cheaper. After the blanks are made, the wing templates can be aligned on them and the airfoil can be cut. There are several commercial devices made for cutting foam wing cores and other parts. Bud Bennett has updated the log for Seismometer. 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. [Peter Sripol] is something of a legend in the DIY RC aircraft crowd. Pegasus H-3 The H-3 Pegasus is a low-wing, open cockpit monoplane by noted lightweight sportplane designer Bert Howland. Don't use the heavier ("pink") foam for flying model parts, in general, although it's good for making plugs. on the other hand homebuilts according to design drawings have endless problems with cracks and detailssimply bcs many designers don,t semm to know how to calculate stresses and forcesit.s ridiculous, when a construction comapny shrugs off a collapsing househmm? 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! Wings are hung to the fuselage with a single strut. and I ordered my bagging materials from CST: Ill add that, Thanks Charlie. There are several commercial devices made for cutting foam wing cores and other parts. The Wingspan is 38.5 inches. on Introduction, Reply Is it OK to use foam for the ribs of an ultralight's wing? I didn't do a very good job of getting the shape right, (got impatient, because it was "just a test") and correcting all those ribs would've been a very long process, and fairly expensive too. 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!) It is based off the Mark III Classic design with some aerodynamic enhancements to generate an extra 10-15 mph cruise speed. This site is currently in read-only mode. How To Make Plugs For MoldsDifferently. Was Galileo expecting to see so many stars? Very stable for a wing, with. Where is the best place in Mich to Learn how to fly a powered ultra-light. The guys not rich, that only makes it worse stop leeching off your parents dude. Are ribs not supposed to be made of rigid, strong, woody and light material i.e pine,balsa etc.? Here's an image you've seen many times, showing the profile of a foam wing and aileron. This can be accomplished with physical pressure on the sheeting/foam/sheeting "sandwich", or by vacuum bagging, which is the superior method. Some manufacturers/shapers had issues while others suffered less, I guess because of their choice of foam core as you mention. There are two options, single page with full plans and two page single wing, just flip the wing template for other side. Probably the hardest thing Peter had to do was to wade through all of the misinformation available by naysayers who are expert armchair engineers with degrees from the academy of negativity. 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. 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. Then calculate the area you will need given a length to chord ratio for your flight regime. It is known for its versatility, light weight, sporty handling and rapid climb rate. / 38.1 cm ) The maximum you can get is one atmosphere, which is roughly 1 bar, right? About: I got started making remote controlled airplanes from scratch as a kid. The answer depends on the wing loading of the aircraft. By using our website and services, you expressly agree to the placement of our performance, functionality and advertising cookies. New research shows that a combination of steel composite metal foam (CMF) and epoxy resin has more desirable characteristics for use as a leading-edge material than the aluminum currently in widespread use. There are motors out there. The Whing Ding is a super-simple ultralight airplane that was designed by Bob Hovey. To qualify as an ultralight, your prospective aircraft must meet certain weight requirements. Peter is not done building, though. Tesla now needs Uranium and powerplants to feed his cars, that.s. so everoyne dould build and fly freely! The function of the diagonal members (to carry shear loads) can be performed by 45 glass fabric on the surface of the rib. What is a good price ? Urethane foam is also fairly light, easy to sand and cut, and has the advantage of resisting most glues and solvents. I glued the strips on the leading edge of the wing before doing everything else. we have easy going and cheaper wood techniques, just the design is less curvy or takes more time to build. The wing structure consists of an aluminum D-cell spar on which the styrofoam ribs are mounted. The seller went from b7000 down to 6000 dollars . 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. It breaks. Here is an example of such a system, this one uses a drop bar:http://www.acpsales.com/Feather-Cut.htmlSanding Wing Cores Smooth After the wing cores are cut, little hairs will be left over. I will liken designs like these to the last gasp flak that cessna and piper were filling the skies with insisting that huge heavy aerodynamically dirty planes were ideal while the kit plane folks and the european theater kept advancing with new materials and ever cleaner slippery cost efficient designs. Here's what this simple wire tool would look like. The relevant calculations have already been done, and [Peter] is already flying an RC scale model of this craft. We already knew how it would work, and wasted less time and material. 9 years ago He obviously read up quite a bit, mentions static testing with 2000 lbs on the wings, etc. 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. Some ultralights have a foam rib core with an aluminum cap strip bonded to the edges to do this. I understand theres many ways to place valuation on a plane, its only my personal opinion that the way to do that has gone awry but I do hope I can convince at least one other person to say wait a minute, this cant be as good as it gets. (The tape can be removed when the foam is glued in place.) Air speed isn't directly the input that decides if a foil fits your use. ? Having said that, it has it's place in modeling, especially in the case of making plugs for molds. 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! 4 years ago Finally, you would probably tack glue the surface back onto the wing, and sand to the proper shape. Foam has some qualities you need to be aware of, as far as how it reacts with adhesives and solvents. The top pair of images is the inside, and the bottom pair is the outside. his birdsshort lived bcs they will fall apart within 2 yrs or simply become a hazzard when binding surfaces and joints weaken in no timebut who cares Consequently, the loads on the single structural members are low, too, so you can get away with foam-only ribs. Powered by Invision Community. Spars made of fiberglass are the key to giving the wing strength. Like an electric ultralight? Trim Excess Away from Trailing Edge The excess must be trimmed away with a exacto and a straight edge.Cut Hinge Line To cut the hinge line, carefully line up a straight edge on the top of the wing and slice down to the kevlar strip on the bottom surface on the wing. With a two-place ultralight, you can take a passenger along for the ride. Now, cut the two required pieces of balsa. Suspension 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. Torsion-free virtually free-by-cyclic groups. So be VERY careful if you use this method. You can use Value XPS to fold airfoil shapes by adding a layer of tape to support the leading edge curve during bending. Some people elect not to use PVA and only use wax. Kolb Firestar. 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. Useful load: 400-445 lbs. I use a silver sharpie on my carbon fiber and it works okay for marking things out. Stack Exchange network consists of 181 Q&A . I used Lowes foam which was a cheaper alternative to rohacell foam. so what? People with means really need to stop taking handouts. All these characteristics combine to give an aerodynamically clean wing with a 12-to-1 glide ratio. 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. Best of luck Peter and thank you for your enthusiasm and your contribution to experimental aviation! 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.) There are a lot of types, but extruded polystyrene (XPS) is common in the US. 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) And solvents wheelbarrow tires finish out the wing will be fabric covered so covering...
