Once you tell us more, I can become more specific. The process was so repeatable that once I had learned Glyph I immediately began scripting the airfoil meshing process, the first step of which, was to generate the airfoil geometry. One of the first grids I generated was an O-Grid for an airfoil. First, you need an Excel file in which you have all the coordinates of the. Generates NACA airfoil coordinates with a mouse-click. Generally, you look at all requirements and then select or design the airfoil according to the desired pressure distribution at different angles of attack and Mach numbers. It was 2008 when I began as a summer intern at Pointwise. The program naca456 is a public domain program in modern Fortran for computing and tabulating the coordinates of the 4-digit, 4-digit modified, 5-digit, 6-series and 6A-series of NACA airfoils.
What construction technique is used for the wing? Wooden frame and fabric? All metal with countersunk or exposed rivets? To be built on a jig or on a flat table? Composite, in a mold or positive over a foam core? All of them have subtle consequences for airfoil selection. Both experimental and numerical works have been carried out on an array of VGs attached to a NACA 4415 airfoil. What is the desired stall behaviour? Docile (as preferred for training aircraft) or snappy (as preferred for aerobatic aircraft)? A study emphasizing the effects of passive vortex generators (VGs) on aerodynamic characteristics of a NACA 4415 airfoil is presented. If the aircraft is small: What Reynolds number is flown at which lift coefficient?. What is the lowest cruise lift coefficient and the highest lift coefficient for a clean wing and with flaps down? Does your design need flaps at all?. However, if you want to operate your design at high subsonic speeds, thickness needs to be controlled. #AIRFOIL GENERATOR ONLINE GENERATOR#
The airfoil coordinates were generated using an online airfoil generator (Airfoiltools) and imported into SolidWorks, a CAD software.
What is the maximum airfoil thickness you can afford? A thicker airfoil makes for a lighter wing with more internal volume for flaps and fuel. First, the airfoil of interest, a NACA 4414, was selected. But since there is plenty of literature on them, they are a good start. You need to be more specific with your requirements, and yes, NACA airfoils will most likely not be the best choice. So you know your wing planform and look for the right airfoil.
