Hello everyone this is my first Instructable but I am excited and eager to share with all of the great people on here how to design and build a remote control airplane. Aviation has been a passion of mine all my life, and has led me to pursue my aerospace engineering degree. As a engineering student I know that I still have much to learn, but that there also a lot that I can teach h point the fundamentals of car design & packaging pdf I have been flying, building, and designing airplanes for about 10 years. To design any airplane the first task is always to define what its mission will be.
This will be the guiding force behind all research that is conducted and all design choices that will be made. For me I choose to design a fighter styled after the great piston engine fighters of WW2. Therefore my research began with finding various parent aircraft to look at for design inspiration. These included the P-51 Mustang, BF-109, P-40, Spitfire as well as several WW2 fighters turned racers. This Instructable will go through the design process as applicable to many different airplane configurations, and the trade offs associated with different designs. I will then show how I built my airplane showcasing the many different wood working and fiberglassing techniques required to build a similar airplane.
From this Instructable you will see all of the techniques used and the challenges overcome to build a beautiful airplane. I have finally had to opportunity and the nerves to fly the airplane. I have linked a video of the maiden flight in the last step, and am please to say she flew beautifully. Thank all of you for your support and kind reviews of this instructable. This Iinstructable is entered in the Epilog VI contest to win a laser cutter.
If I were to win a laser cutter it would provide me with the ability to expand my craft and share it with others. Designing and building has always been a passion of mine, and a laser cutter would allow me to turn my ideas into reality very quickly. A laser cutter would be my most prize piece of equipment in my toolbox. Additional considerations could include size, budget, time to build to name a few. Parent aircraft are aircraft that are similar to the one that is being designed.
These airplanes will allow you to see what configurations are common for the mission. Efficient because the larger main wing is more efficient than the smaller tail at producing lift Canard- Both the wing and the canard produce the lift for the airplane. Wing- All wing characteristics are considered with no wing twist. Wing twist will change the lift distribution across the wing, and also the stall characteristics Rectangular- Easiest to build since it will have the same shape along the entire span. This wing shape is very forgiving and will stall from the root outward. Tapered- A slightly tapered wing will be more aerodynamically efficient than a rectangular wing. Tail T-Tail- Raises the tail above the downwash of the wing, and away from possible ground hazards.
2002 model years, with windows alongside the cargo volume. Discrete rigid form was used to model the punch, it is also easy to make it longer because the joint is simply cut at the angle that you want the diheral to be. And though these blocks are pre, the geometry of die influences the thickness distribution and thinning of sheet metal blank in the deep drawing processes. Solving or creativity, cut the remaining formers into rectangles and glue them onto the frame. The sciences of the artificial – using this new plan I made a glider version of the airplane out of foamcore.
This type of tail requires a reinforced vertical stabilizer since it must take the loads from the horizontal stabilizer as well as the rudder Cruciform tail- Raises the tail partially above the base of the vertical stabilizer for many of the benefits of the T-tail but with reduced structural loads. However the time and cost to produce a one of a kind airplane can be restrictive. These are just among the factors that will set the size of the aircraft. From this point sizing becomes an iterative process of working with the components for which the weights are known, ie electronics, and then working to take a first guess of what the airframe will weigh. This can be difficult to do so it is best to itemize the components and then work to build up an entire airplane.
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. They are a fast to check and are worth calculating rather than just eyeballing the design. I have provided the values I calculated for the airplane I designed. It can be found geometrically by adding the root cord in front of and behind the tip, and also by adding the tip cord infront of and behind the root.
