I. Jason--Thanks for the detail. The clevises are threaded on to the rod, one of which with tread lock to prevent the pushrod from being able to rotate and unscrew out of the clevis. Below is the first stage of building the reinforced ribs. This setup reduces the weight of the control rod verses a comparable metal one and is easier to set up than the plastic tube control rods. The wires you see are from the landing gear. In comparison to the wings sheeting the fuselage is an entirely different challenge. These markings can be seem on the first picture of the fuselage with the firewall mounted, sorry I missed getting a picture of it before it was installed. Wipe down the fiberglass with rubbing alcohol to remove any wax residue. Delta-efficient for high speed flight. This is critical since mounting the landing gear so that it is angled in or out increase the stress on the gear when landing and thus the chances of the gear collapsing. The RC airplane design calculator has been created in order to provide an approximation of specific airframe parameters. The reinforced former in front of the wing has a hole cut into it to accept the peg from the wing. The canopy is constructed similarly to the engine cover with the exception that a pre-made bubble was added into the construction process to be the shape of the canopy. Once again this control surface is constructed very similar to the wing. Foam- Fast to build and durable, however the airplanes are generally heavier since the foam requires substantial reinforcements to to be able to with stand the flight loads of a substantially sized airplane. Once the balsa pieces are stacked to form the tips, cut out the top view of the tip into them. This will allow for a large spar for increased strength and also for landing gear to easily fit inside of the wing. The task employs a series of steps and skills that can be acquired by anyone. You can see the final truss design marked out on the fuselage cross sections as boxes. First glue the spacers onto the inside of once of the fiberglass spacers with thick CA. A good starting point is to thoroughly understand the requirements of the aircraft that you are designing; here are some questions you should ask yourself: Once you are clear which factors will drive the fuselage design you can start to sketch a preliminary outline of your fuselage. Use a squeegee to wet the surface with resin. It is good for the shaft to have play in the vertical direction, however lateral motion should be minimized. Wet the next sheet of fiberglass and after squeegeeing out the excess epoxy place it onto the previously placed fiberglass ply. How is my aircraft powered? A slenderness ratio (length-to-diameter) of between 5 and 6 produces the minimum drag case. The pockets need to be large enough to allow the drive shaft to rotated freely within therefore I made mine 2.5" long. Aerodynamic Lift, Drag and Moment Coefficients, Introduction to Aircraft Internal Combustion Engines, The Aircraft Electrical System – An Overview. However, you may notice that some pictures that I reference may be further along than described to that point. I also knew that I wanted to make it fully sheeted with balsa and fiberglass, because I love the look of wood. I'm building a flying wing and didn't know about the 3D capabilities in AutoCad. The basic methodology behind the structural design of a fuselage is to ensure that the skin/stiffener combination does not buckle between transverse frames. Sorry that it has taken so long to finally publish a video if it flying, but i did not have access to a paved runway while I was at college. This design methodology was born out of the use of aluminium rather than steel as the primary structural material used in the design of aircraft structures. These motors has increased efficiency over brushed motors do to reduced friction and increased electrical efficiency. Begin laying pieces of fiberglass around the cowl building up one layer at a time. It would allow me to rapidly design and test new ideas and building techniques. The angle of the horizontal stabilizer must be slightly nose down to ensure the stability of the airplane, otherwise it will be unflyable. It is attached with a series of bolts. Therefore I twisted the wing tips down so that they will stall after the root. Once sheeted drill 2 holes into the lower balsa rails and install a wire into the holes. Lay the boards being glued face down on the the working surface with the edge being joined over the packing tape. Tip- The outermost portion of the wing designed to streamline the end of the wing. In a semi-monocoque structure both the skin and set of frames are load carrying and contribute to the overall stiffness of the structure. I used 3 pieces per layer: top, left, right side. Sketch the airplane- First I drew my preliminary design sketch on graph paper without any dimensions. Aerodynamic loads as a result of the aircraft maneuvering through the air. Cut the trailing edges of the rib out of 1/16" balsa. Glue the horizontal stabilizer in place using 5 minute epoxy, since it will produce a very strong bond while also filling any gaps that my be hard to see. The wings are a one-piece design with a fiberglass spar on the bottom wing. The main aim of this project was to design, analyze and build an . Therefore I re-scaled my preliminary drawing to have a 60 inch wingspan (Wing area=630in^2) not counting the wingtips. ahoy...a very compelling build log....I build my planes as a favorite past time....alas I can't build all of them at once..and lo..there is a way to design ones own, great job. Once the cowl has cured put on the appropriate protective equipment and sand the outside smooth. Step 1. Wood was chosen over a composite tube because the airplane is designed with 2 degrees of dihedral and the joint in the center of a composite tube wing would difficult to make strong enough to withstand the bending load. Since I am leaving the wood grain exposed when the model is finished it is important to match the grain and color of the board to the piece next to it. It will likely not be as long as the upper member since it will hit the horizontal stabilizer. Additionally on the control horn side the balsa is cut back further to allow a piece of basswood to be installed. Once again the wing was placed nose down on the table to ensure that the wing was mounted straight. Excellent work. Stiffeners and stringers are responsible for transmitting the axial loading (both tension and compression) that arise out of the bending moments induced through the fuselage structure. Once the shape is close use the tape technique that was used on the wing to protect the ribs as the sub leading edge is sanded. The fuselage structure will not fail due to excessive loading throughout the entire aircraft flight envelope. See more ideas about model airplanes, rc planes, rc airplanes. The mount must also be made as lightly as possible since it is difficult to compensate for a tail heavy airplane with out adding a lot of weight to the nose. They are a fast to check and are worth calculating rather than just eyeballing the design. Here I will describe how the center wing ribs were attached and then how the landing gear ribs were fitted to the wing. If it is off a spacer between the shelf and the servo may be required. RC. V Tail/ Inverted V- Less efficient than a conventional tail since lifting forces are pointing in a direction other than the desired on increasing drag during maneuvers. These airplanes will allow you to see what configurations are common for the mission. I think it was probably 20 hours easy, plus the time that was spent proof reading after that which thankfully I had some help on. Install the flap servos in the wing as was done on the ailerons. If you aren’t asking about specific aero dynamics then there is going to be one big rule you need to make your RC plane controllable. Also it is important to take into account if the wing had dihedral since the gear will then either have to not extend 90 degrees or it will need to be mounted at an angle in the wing, in my case it is mounted in the wing at an angle. Efficient because the larger main wing is more efficient than the smaller tail at producing lift. Use the fuselage as a guide to sand the formers to shape. These are to increase the rigidity of the nose of the airplane. Cut the rudder off of the vertical stabilizer using a razor saw. fuselage 3. This Iinstructable is entered in the Epilog VI contest to win a laser cutter. Now using the “section plane” button at each of the wing rib locations a cross-section of the wing will be generated. Gently lift the sheeting up being carefully to not bend it to far and crack it. tell me honestly how long did it take you to do this instructable up? This was done to ensure that if the gear was damaged or moved during flight it would still be able to open or close. The sub leading edge is 1/4" thick over sided balsa strip that can be glue on to the ribs with thick CA. The rotatory drive system that I purchased did not include a set of pockets so they had to be fabricated. The location of doors and windows on the fuselage is another important consideration that must be carefully studied. I began by making preliminary holes in the upper deck of the the truss to allow the surface to be test fitted. The trailing edge / drag spar is made from 1/16” thick balsa sheeting, it helps add to torsional rigidity while also unifying the wing ribs to allow the control surfaces to be mounted to the back of the ribs. This airplane design calculator assumes that the shape of the wing is of a constant cross sectional area. Great starter plane and plenty of parts around to repair it. Starting with the center of the wing cover the section the is inboard and forward of the gear doors. The shear web is made from 1/32” thick basswood sheeting, and is glued between the upper and lower spar caps to join the structure. 1.1. To aid in aligning the wing ribs during construction I highly recomend drawing a horizontal line from the trailing edge of the wing through the leading edge. Sheet the first side of the vertical stabilizer using one of the methods used on the wing. To save time constructing it I had purchased strips of 1/2x1/16x36" hard balsa to make the corners out of, however it was challenging to find enough straight pieces. The wing tips are simple to make however they can be rather time consuming to achieve the desired shape on both wing tips. All Up Weight: 425 grams . From here there are general guidelines for how many watts of power per pound are required. The first rule is that edge joints are no longer an acceptable way to join sheets because they will be impossible to align and will easily brake on the tight curves being made. It had substantially better low speed performance than i was expecting, and was very maneuverable. I have finally had to opportunity and the nerves to fly the airplane. All sheeted surfaces on this model are covered in 1/32" thick balsa wood. Things to look for include very tight ribs,very loose ribs, and that the spar cap is fully enclosed by the spar slot in the rib. Stand one strip of balsa upright in front of the straight edge and then lay down the second piece flat on the table to hold the other piece in place. The top section of the fuselage truss is flat in respect with to the direction of flight, therefore once this was trimmed to be perpendicular to the table the firewall could be set with 0 degrees of down thrust. An ESC must be selected that can handle the desired voltage and current of the motor. Rectangular- Easiest to build since it will have the same shape along the entire span. Question I have tried making beams like this previously with wood glue and have found it to be a headache because the water in the glue will swell the wood along the joint which will bend the beam. Put on a pair of gloves and ensure there is adequate ventilation. It is also a good platform for beginners to learn about flying. Glue together 4 layers of 1/16" balsa to make a piece of plywood for the rear former of the canopy. I had to drop out do to the cost of insane tuition and a complete lack of preparation and funding. This Instructable is entered in the Epilog Challenge VI and radio control contest, and please feel free to comment with questions I will be more than happy to help. It is made from 1/8" thick plywood and has lightening holes in it to reduces excess weight. The lower spar cap is installed as two separate pieces and is joined in the wing unlike the upper spar cap that was was installed as one piece. RC CAD is a software specially designed to help modelers to create airplanes. Again since these templates are actually the wing skin the inside of the innermost line is the correct one to cut on. To efficiently design with steel, engineers had to make use of very thin sections which were intricately curved and shaped to prevent buckling of the thin structure. Nearly all of the airplane is sheeted balsa covered with .75oz fiberglass. The heavier way is to build the sides from thicker balsa. Conventional tail- The standard for most airplanes. Make a jig to hold the spar stock while cutting. First cut the rib shape from from 1/32" basswood and sand the rib as done on the previous ribs. As a general statement to produce the same power a high kv motor will spin a smaller prop faster while pulling a higher current(higher current=lower battery life) compared to a low kv motor that will spin a larger prop much slower and with a much lower current draw but at a higher voltage. Since the flaps are thicker than the ailerons an additional layer of balsa may required to make the front of the flap circular. Therefore the only method that I had available to me was to make my own templates for each rib and then cut and sand each rib until it was the perfect fit. Squeegee (clam shell packaging works great). To import an airfoil into autocad the fastest method that I have found has been to open the airfoil text file with excel so that it will organize the data(these files for many airfoils can be found on the UIUC airfoil database). Lastly I wet and applied the glass to the nose of the fuselage. Not every flight is a smooth one and should your Electric or Gas RC plane ever need repairs, we have you covered there, too. Apply a piece of duct tape along the ribs that it will be sanded in front of. Making A Fuselage Preparations. To do this the segments of the spar that are sticking out had to be very firmly attached. Attach the drag spar and sand as was done of the wing. Generally it is good to start by creating a number of cross-sections of your proposed fuselage over the critical components and then begin to join them up to form your preliminary design. Select the sheets of balsa that will be joined on the edge. A fuselage structure is loaded in a number of ways. They are all made from 1/16" balsa, with the exception of a few structural ribs that are made from 1/8" plywood. The fourth wing has a fully boxed spar with shear webbing on both the front and back of the spar. Using various thicknesses of balsa as required to build up the required thickness up to the door on both the front and rear side of the door. Using a piece of basswood carve it down into a wedge to and then sand it until it is the perfect angle to mount the gear straight. This is a plane I designed using RCTestFlight's fuselage from his Slow Trainer. Trainer Design By reducing the dimensions of a full-sized aircraft proportionally, a scaled model will be obtained, however, it seldom becomes an easy flying one. Additionally it contains an air scoop to cool the motor. As such it is of the up most importance that the wing spar is strong enough to withstand the loads it will be subjected to. The remainder of the structural ribs can be done at this point with the exception of the landing gear ribs. Glue thin strip of balsa onto each side of the pocket till it is the thickness of the opening in the aileron. It may still be possible to cover this area however it will likely require more than one piece of covering. At that point I replaced the two pico servos with one high torque micro servo). Sand to the final shape and rough the surface to that it can be written on easily. I chose to install two brackets. People who think fuselage sides should be made from lite-ply shouldn't be designing model airplanes. Mark where the elevator will begin on the ribs and then cut off the excess rib material with a razor saw. It lets you create airplane models with particular specifications. Then cutout the sheeting and verify its fit in the position of the flap. The hinge is a rounded control surface with the pivot point in the center point of the circular leading edge to minimize the hinge gap and to have smooth edges. This overlap allows the joints to come together smoothly and also allows them to be sanded after the sheeting is in place. Flip the wing over and while supporting the skin from underneath use small drops of thin CA along the joints to glue the sheeting on. Hollow out some of the foam so that is can fit over the motor, then bolt it onto the airplane with the spinner. Place a bolt through through the landing gear into the drilled hole and then drill the remaining holes using the gear as the guide. Basswood was chosen for the since it is a hardwood with a very straight grain, furthermore it is very strong for its weight. Concentrated point loads: for example the interface between the fuselage and the tail. This maximizes the strength of the part by allowing for continuous fibers along the length of the part. The higher the Reynolds number the larger the chord), this means that the root if at the same Reynolds number (same chord as tip) would stall first and thus the airplane would maintain role control. One precaution that was used on the canopy was wrapping it in tape to preserve the frosted look by ensuring that resin would not get on the bubble. In my case I ran the grain along the leading edge, this will leave the center of the wing with a V where the grains of the wood come together, however since this will not be seen I can accept this. The vertical and horizontal stabilizer must be mounted precisely to ensure that the correct angles are achieved. Trace the wing rib shape onto 2 oz fiberglass leaving about 1/2" around the outside of the ribs as shown in the photos. Then using the trailing edge and the mark on the leading edge mark align the rib so that the mark and the trailing edge are the same height above the working surface. The distribution of these point loads into the skin structure becomes very difficult to efficiently achieve. RcCad is another free aircraft designer for Windows. Cut sheets of basswood with the grain to be slightly wider than the spacing in between the wing ribs. LEARNING FROM THE NATURE. The outer gear doors are attached to the landing gear and move with them. How Does the RC Plane Work? My name is Bruce Stenulson, and I've lived in the central Colorado Rocky Mountains for over 37 years. This large angle will make it difficult to assemble the wing later on due to the large amount of excess wood and sharp angles on the edges of the ribs that will need to be removed. Apply a small amount of epoxy to the center wing rib and align it on the spar as done previously. The pictures in this step are all labeled with the step that they go along with. I did have to clean the joints after the resin cured, this was done by very carefully running a razor saw though the gaps until the doors moved freely. It would also allow me to share my passion and love of aviation with others. Furthermore I had mis-measured the space required for my landing gear so I had to adjust the size of the landing gear cross members that connected the landing gear to the ribs. Cover the other side of the horizontal stabilizer by slowly working your way from the leading edge back, by bending the sheeting up and applying thick CA to the ribs. The construction was complex with many formers … Article by RideElectric. Next adhere the vertically grained core onto the the rib blank. The flaps will be constructed later on. Double or triple tapered wing- Used to increase the efficiency of a tapered wing by making its lift distribution closer to that of an elliptical wing. To have a successful airplane it is paramount to calculate a few stability terms to ensure that the airplane will be stable and thus flyable. Once the correct position is found mark one of the mounting holes and drill using the appropriate drill bit being careful to support the end of the wings so that the end ribs are not crushed. Install the leading edge onto the flap. With the appropriate safety precautions remove the excess from the ribs. Check out these sources of 3D printed RC plane parts which will get you flying again in no time! AeroFred is almost the Thingiverse of the RC planes. Repeat steps 5-11 to the other side of the rib and to all remaining ribs. The lower spar cap can be challenging to install since it must fit into all of the spar notches in the wing with out being such a tight fit that it actually twists the wing, after all the effort was spent ensuring that it was constructed with the desired twist. To join the truss sections together I first tacked them together with CA, then installed a balsa doubler inside the truss at the joint between the sections. Use a paper towel to wipe any remaining dust off of the part. Parent aircraft are aircraft that are similar to the one that is being designed. Cut the remaining formers into rectangles and glue them onto the frame. This step will prevent the skin from being wavy and going up and down between formers. Creating an original model airplane designis a challenging and rewarding aspect of the RC flying hobby. Fitting the landing gear proved to be challenging due to the the wing being rather thin. Abandoned Application number US13/987,314 … Glue the sheets of 1/32" balsa together as was done for sheeting the top of the wing. To add to the challenge the shear web was installed on the leading edge of the wing, this had its own pros and cons. Draw the blue print to build on and then cover with wax paper. Begin test fitting the other side of the spar cap, in addition to checking and fixing its fit with the wing ribs. Now cut the middle rib so that it can be installed in two pieces on the spar. Excess fiberglass around the edges can often be first cut with scissors. The fuselage slenderness ratio (ratio of length-to-diameter). The earliest aircraft fuselages were built with a space frame or truss like construction. Shear webbing is absolutely necessary in a wing since it dramatically increases the rigidity and strength of the wing for very little weight. That is enough about how the gear works lets get to how to build them. It was completed in four pieces in one wet layup: right top, left top. Glue in the hinge pockets and then the hinge block into the aileron. Helpful. In my case this alignment would give me the 2 degrees of washout that I desired. The key to smooth sheeting and tight joints is to dry fit again and again, and to lightly draw alignment marks on the pieces being sheeted to help align the work when gluing it. This requires the main airplane wing to be rectangular in shape when viewed from above and as pictured below. To design a plane, engineers must understand all of these elements. Trace that view onto the other tip and cut it out. Be careful to not apply too much or else it will soak into the surrounding wood. However this comes at the price of a higher current draw, and the BEC or receiver pack must be carefully sized for the number and size of servos being used, Determine the level of performance that you desire out of the airplane. In my case it had to be because the wing had dihedral and my landing gear extends a full 90 degrees, therefore if they were not they would be bent outwards when extended. I took pride in the planes I built for scratch kits in the past. Glue on a base made from the same material as the bottom, being sure it is aligned with the bottom piece. Continue dry fitting until the edge of the new sheet comes to end of the scarf joint on the sheet on the other wing. Once glue has been applied to all of the joints insert the spar cap. One additional but important consideration is the design of the cockpit. Using sand paper rough up the side of the servo that is being glued in. Therefore the frames must be stiff enough that they do not buckle globally, and the skin and stiffeners, which form a series of segments on the fuselage, must not buckle locally. It is made from a 4mm carbon tube with 2-56 threaded rod epoxied about 2 inches deep into the tube on either end. The pocket is also build using 1/16" inch bass wood with the edge of the bracket being supported with 1/8" inch basswood. Measure out the spacing of the ribs and glue them into place. However towards the end of the door fitting one of the servos had an electrical glitch and would no longer respond. Down thrust is include to reduce the airplanes tendency to climb as the throttle is increase. Now that the sides of the truss are formed they must be joined. The process that is being used to apply the fiberglass called a wet layup since the resin is being used to wet the fibers. 4 years ago. On the back side attach the gear with a washer and a nylon lock nut to ensure that the nut never comes off since it would be very difficult to replace and also could get stuck in the landing gear mechanism. A spacer is used to prevent the gear from striking the door as it opens. Us a sanding bar to very gently sand the formers. Place a ruler between the marks and then mark all of the ribs, additionally make the location of the center of the radius being made for the hinge. A well designed fuselage will be optimized for payload, weight, aerodynamic drag and the ability to stretch or shrink in length to accommodate new variations or configurations of the aircraft during its life. Remove the cowl from the airplane and cut enough 75oz fiberglass to put at least 4 plys over the entire cowl. If I can give one person the tools or motivation to take his/her craft to the next level then this has been a successful Instructable. Build a mounting shelf as done for all the other servos in the aft section of the fuselage and epoxy the servo into place on it, being sure to line up the control arm with the control horn on the elevator. Important considerations are the curve in the edge since no boards are actually cut straight, the wood grain, wood color, and hardness. The wing is then hollowed out using “solidedit” and then selecting “shell”. Be careful to not add to much or else it will seep through the skin. Fabrication is difficult since all ribs are different sizes and do not uniformly change in size. The payload of civil aircraft can consist of passengers, baggage and cargo. Axial loads are carried by the longitudinal stiffeners and stringers. The recommended build material when using the design parameters for the RC airplane design calculator is foam board. I will then show how I built my airplane showcasing the many different wood working and fiberglassing techniques required to build a similar airplane. Fuselage Design. Dry fit the sheeting and glue it in place. Since the landing gear doors are thicker than the sheeting on the wings they will stick out beyond the skin, therefore a fairing must be made. Fuselage Construction. Some early types had tandem stacks of multiple planes, such as the nine-wing Caproni Ca.60 flying boat with three triplane stacks in tandem.
