Posted By Lucie Gaget on Jan 10, They are becoming an essential tool for the aeronautics and aerospace industries. More and more engineers are using 3D design software in order to 3D print, for prototyping or production.
But it can also be used for the visualization of a project. For aircraft design, engineers need to create technical 2D drawings and 3D models. A lot of specific features have to be offered by this kind of software to allow the creation of mechanical designs and reliable aircrafts. In this blogpost, we will see why 3D modeling is becoming so important for aeronautics.
And as we know that finding the right Computer-Aided Design software can be a real challenge, we decided to help you with a selection of the best aircraft design software. The 3D printing technology is taking more and more space in the aeronautics sector. Indeed, additive manufacturing is becoming a great asset for this industry. If you want more details, you can read our blogpost about the future of 3D printing in aerospace and aeronauticsand see how an online 3D printing service such as Sculpteo could help you.
Indeed, the way parts are designed and produced is progressively evolving thanks to additive manufacturing. Engineers are now able to create parts with intricate or conceptual designs at the same costs as parts with simple geometries.
In order to change the manufacturing process and start using 3D printing, engineers have to find the right software to design those kind of complex projects. Aerodynamics and aircraft designs are requiring tools with a high level of efficiency and accuracy.
Moreover, airplane designers need a lot of analysis features and design tools in order to create an aircraft with optimized flight conditions. That is precisely where CAD software is becoming an interesting tool.
It can be used for the visualization of a project, for analysis, but also to do some rapid prototyping or directly for production. These projects require programs able to use the finite element method in order to resolve problems linked to structure or fluid flow for example.
In aircraft engineering, you have to be able to get aerodynamic analysis, to modify geometries and get accurate views.
In order to help you in you researches for the best aircraft design program, we made a top of the best software for aeronautics. Aeronautics require accuracy and efficiency.The scale model RC airplane has to be balanced but where is the position? There are many schools of thought regarding where to balance a scale model RC airplane. I do not wish to get into any arguments with aerodynamicists, who know far more than I do but I would like to pass on the information that I have used to successfully find that elusive and so important point!
The above photo does prove that the methods listed here do work and are fairly simple to use. If you would like more info on the Fantome or even purchase a set of plans visit this page. For the scale model RC airplane, I prefer to take these facts into consideration. When designing a scale model we do not have the ability to change dimensions or ratios-we are restricted by our wish to build an accurate reproduction of the full size.
For a constant chord wing the MAC is obvious but for tapered or swept wings it is not so easy. However a simple graphical method is shown here. Draw or trace the wing shape as shown. Then extend the Leading Edge L. Also square off the tips. Now extend the opposite chord lengths as indicated on the drawing; i.
The four extreme points are then connected by diagonals. The Moment Arm was found to be Say 5 inches. For the scale model RC airplane with an elliptical wing, such as the Spitfire, we divide the wing area by the wing span.
The result is the average chord. If you now move your ruler along the wing plan, until you find this dimension, this will give you the position of the MAC or at least close enough for our purposes.
Do a similar exercise for the tailplane and you will now be able to find the moment arm. Now you should have all the information to plug in to the formula. If the scale model RC airplane you are designing is a delta or of a tailless configuration then the formula reduces to. This point is the CG or balance point.
If you are still having problems locating that elusive balance point on your scale model RC airplane, then please contact me via the "Contact Us " page.

Use this airplane design calculator to help you determine key airframe dimensions along with an approximate target weight and power for your radio control aircraft. The recommended build material when using the design parameters for the RC airplane design calculator is foam board.
Design. Test. Print. Build. an Aerodynamic RC Plane (Tutorial)
Building with foam board allows a lightweight, inexpensive and easy to build airplane. This airplane design calculator assumes that the shape of the wing is of a constant cross sectional area.
This requires the main airplane wing to be rectangular in shape when viewed from above and as pictured below. Each calculated parameter can be reviewed in the image below to better understand where the dimensions are measured from. To use the calculator simply select the type of airframe that you are building. Next, enter the wingspan of the airplane you plan to design and make.
The wingspan of the airplane is entered in imperial inches units. Airplane Design Calculator — Use this airplane design calculator to help determine specific dimensions of your design. Made with by Graphene Themes.

Trainer Sport Glider.The design of RC planes, can be simplified, so that you can fly your own, maybe one of a kind, scale model. Can you design your own RC aircraft, possibly a unique scale model, that is the envy of flying buddies?
Yes it is possible, but be prepared for a LOT of work! You must be a somewhat experienced model builder, with a couple of kits under your belt. If you can see how to improve things, in the kits you have built, then you will love being able to do things YOUR way, in your own RC airplane.
Where to start? I know I have a list of "to build" scale models, and I seriously doubt, if I will live long enough to complete it! You can of course, design to any size you prefer and chose the power source you like, even go to an RC electric plane.
See how to choose the best scale RC model aircraft for you. I have found it very useful, to have a plastic model available, during the design and build phase. A few other useful tips, can be found ,by reading about plastic model aircraft. A 3-view drawingof the desired plane, is almost a necessity, read how to find the set of scale aircraft drawings you need for your next project.
Click here for more details. You may find more than one 3-view and see differences between them. Drafting of your own plan, may seem to be a daunting task-but it may be easier than you think. You do not have to be an experienced draftsman-after all you maybe the only person to see the fruits of your labors! Mechanical drafting, using a Tee Square and set square, can be very rewarding.
If you use drafting paper. A set of compasses and French curves will make the job that much easier. If you have the experience, then CAD design can be extremely accurate and some CAD programs are very good at importing scans of 3-view drawings. I have used Autocad for many years and now use it exclusively for drafting of RC planes. See this page - "Radio Controlled Planes and how to Balance them.
Click here for more information. If you are designing your own, then you are on your own! When building that new RC airplane, keep your bench top tools organized and right at hand! Click here for full details. Maybe the best advice I can give you, is to direct you to a book I purchased, several years ago, and unfortunately is now out of print.
This reference is used every time I start a design. Some of the information is way out of date, but the majority of it is applicable and very useful.
Try and find a used copy-But do not pay too much! Some of the prices I have seen are crazy! For a look at a library of RC airplane design books- just click here.

Written by Peter Carpenter.It opened an entirely new segment of modeling to me, while also greatly increasing the precision in which I designed and developed scratch build scale airplanes. I have been using CAD programs now for more than 20 years and this post is an online version of my presentation for drawing 3-views and developing plans to build RC airplanes.
There are several reasonably priced CAD programs intended specifically for modelers looking to start playing with the design and drawing program. The program is in my opinion, the easiest and quickest CAD program to learn. I have designed many RC airplanes using Graphite and I am now using version 9. I then simplifed and added modern hardware to the design. It turned out to be a great flying airplane just like the original Kaos When it comes to scale airplanes, CAD allows you to duplicate any airplane there is.
Just start with simple designs and work your way up to more complicated ones. The other way to produce drawings, is to take direct measurements of the things you want to draw. For the development of plans where you trace an existing airplane drawing, there are some rules I made that make the job a lot easier. After developing your front, side and top views of your model, you have to make sure they are all to scale with each other. Now make a mirror image, flip it around and add it to this one and you have a complete wing plan.
Just download the airfoils you need and add to your CAD File. Just like everything else, you develop the ribs starting from the outside of the basic airfoil shape and working inward in steps. You can also loft ribs if you want to develop your wing with a progressive airfoil shape that changes from the root to the tip. Start with the wing planform, and the rib placement. Make sure the ribs are spaced evenly. The stack the airfoils and divide into a number of stations. Connect the station lines from the tip to the root rib.
Then divide these lines by the number of the ribs you want. If you want 10 ribs, then divide the lines into to 10 equal sections. Using the spline tool, connect the dots and you develop the individual ribs.Here, I will show you how I made my twin motor RC airplane with a 75in 6.
These instructions will show you the basic ideas you need to think about and do when designing and building any RC Airplane. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Why do you want to build a model airplane in the first place? It could be just to have fun with and fly around, or you may want to attach a camera and get some Aerial Photography and FPV.
You will need to choose what electronics to use for your aircraft. Pick a motor and battery that will give you a decent amount of thrust, and fair flight time. For this plane, I used 2 motors that would provide roughly g of thrust with a 10x4. I found that with a mAh 2. So, in all, I will have two mAh batteries on board. Determine what controls you want your model to have, and purchase an appropriate Receiver. This is 5 channels, so I will need at least a 5 channel receiver.
After equating the required spot on the receiver for the BEC we'll get to that I went with an 8 channel receiver so I would have plenty of free plugs. I knew this plane would turn out quite large, so I chose to use larger servos, which draw more Amperes. So I had to use an external BEC.
The BEC basically takes power directly from the battery, and drops the voltage down to a desired level, and sends power only to the servos and Receiver. Now, with all of your electronics chosen, you can add up their weight and be sure to add in a large margin for the weight of the model itself. The total weight could be 2 to 4 times the weight of all of your electronics. I estimated that my plane would weigh about g total.
Now that you have a total weight estimate, you can use the desired flight handling affected by Wing Loading to calculate the total amount of wing area you need for your plane to fly.
The best way is to use an online calculator such as the one here:. Plug in your model weight, and experiment with different "Wing Areas" until you get a low wing cubed loading. The lower the better. I always try to start out with my models being in the "Glider Category" since after it is built it will most likely be heavier than you calculated, which would put it in the "Trainer Category", which in my opinion is the best for fun flying airplanes.
I found that square inches would give the plane a Wing Cube Loading if 4. Now that you have the total wing area needed, you can divide that number to find a wingspan and wing chord width from front of wing to back. Any combination of wing chord and wingspan that multiplies to get your total wing area will work, but different Aspect Ratios are also important. You can find the aspect ratio of the wing by taking the wing chord divided by the wing span.
High aspect ratio wings having a lower number - yes, its confusing are generally used for gliders and trainer airplanes, while Lower aspect ratio wings will be used for more aerobatic models. A high aspect ratio basically means the wing will be long and skinny, while a low aspect ratio wing will be short and wide.

Since your wing dimensions are already set, now you can design the tail and fuselage. For my plane, I went with a Horizontal stabilizer area of inches squared because it just looked right in my drawings. Horizontal Stabilizer dimensions: 26in by 9 in.These are fairly basic and easy to calculate formulas that will give a good indication of what to expect from an aircraft before flying it for the first time.
Some of these formulas depend on a rudimentary understanding of Trigonometry. I have attempted to explain just what you need to know as simply as possible.
The series teaches you how to do the math to convert angles to measurements, calculate areas, etc. If you want to learn how to determine the correct amount of side thrust, the correct wing dihedral or similar information then you will need to consult a trim chart. Before you can even begin to trim your model you must locate the correct Center of Gravity. If you fail to do this then any other trim adjustments you make will be wrong. Trimming a Radio Control Model Aircraft These links to external websites are provided to help you determine how to properly set up and trim your radio control models.
May 05, Useful Formulas used with Flying Model Aircraft The formulas presented on this page should be helpful to newcomers to the hobby. Aircraft Proving Grounds — Provides a great deal of information beyond typical trim charts. This is a freeware program that will convert just about any unit to any unit. Another way to convert units is to simply type your question into Google.
I found this by accident by simply deciding to try it. Go to the Google homepage and type the number of units and the unit type into the search box.
Then type "to" and the units you want to convert. Type without the quotes" ounces to grams " to get the conversion. Please Excuse My Whining Dept. Think of an odd number greater than Got it? OK, divide that number by 16 in your head to determine the decimal equivalent Have an answer?
