It is important that you do a little bit of research for the airplane that you're wanting to design. He requires doing research, learning how to read a Coefficient of Lift v Alpha chart and choosing your airfoils. Use all of your views to make sure that you have placed it correctly on the Y axis and that you have placed it correctly on the Z axis.Īlthough this was only two steps the set up process and getting our main airfoils in place does take some time. All you need to do is move the Y axis and the Z axis into position. It is actually on the correct access at this time. Simply zoom out until you see where it is in your workspace and move it into position.ĭo not be tempted to move the airfoil sketch by the X axis. If you zoom out far enough you will notice that the airfoil actually is within your workspace, it’s just not where we would like it to be. Don't worry, this is a strange behavior within the script. ![]() You will notice that the CP will disappear, and you will not see the airfoil sketch appear. Then press “OK” in our “Airfoil Parameters” pallet. ![]() Next we make sure that the select button is highlighted in blue then select a route construction plane that we placed in step one. Doing it this way ensures that our court will be the exact length we need for our route airfoil. Where you enter the cord measurement delete what's in the field currently, and then press command V or “Control + V” to paste the dimension that we copied from the box tool. Double tap this script and it will open up the airfoil parameters pallet. You will see the Airfoil DAT to Spline tool under the scripts section. This will activate your add-ins and scripts pallet. To activate this tool, you will need to hold down the shift key and then press the letter “S” (Shift + S). With that little hack out of the way, we will use the Airfoil DAT to Spline tool. Take your time, learn to read Lift Coefficient v Alpha charts and you will be fine. Nor do we have wind tunnel facilities to test our wings in the most nuanced and precise ways available to the pros. Most of us are hobbyists, without a degree in aeronautical engineering or with a deep understanding for fluid dynamics, can fully understand or appreciate the intricacies and study that goes into efficient, predictable wing development. Wings are difficult to design and there’s a lot of physics and theory in this specific topic. It took 3 or 4 complete wing design iterations to finally settle on one which you can see in my current design.īe patient as you work through your design. To come close to this design, while also having a flight characteristic I’d prefer in my model, I pulled several airfoils and worked on blending them. Since I was unable to find actual technical information about the wing design and the specific airfoils they used to develop the L-1011, I had to approximate which AFs to use. The full scale plane used a supercritical airfoil at the root and twisted to produce washout at the wing tips. The airfoil at the wing’s MAC (Mean Aerodynamic Chord) is a transitional airfoil that blended well between the two different AFs Two of which are the NASA CS(1)-0614 Supercritical and Curtis C-72 High Lift Airfoil. As I’ve noted, for my RC Airliner, the L-1011, I’ve chosen three airfoils.
