It is the same as inputting it on ‘coeff-20’ tab. You can also input your airfoil’s aerodynamic characteristics from the input boxes in this tab. The only difference is that the figure box on the rightside is showing a graph of Cl, Cd, and Cm versus AoA with AoA ranging from -180 degree to 180 degree instead of from -20 degree to 20 degree. In ‘coeff-180’ tab, you’ll see similar window with the one when the ‘coeff-20’ tab is selected (see figure 2 below). In this tab, you can input your airfoil’s aerodynamic characteristics from those input boxes and see if the graph on the rightside matches your airfoil’s aerodynamic characteristics reference graph. In this tab, the figure box shows a graph of Cl, Cd, and Cm versus AoA (each presented by the green, red, and yellow line respectively) with AoA ranging from -20 degrees to 20 degrees, while there are a lot of input boxes on the leftside, as shown in figure 1 below. When you start your Airfoil-Maker, ‘coeff-20’ tab is automatically selected. Just right below the toolbar, there are four selection tab, each labelled ‘coeff-20’, ‘coeff-180’, ‘finite L/D’, and ‘camber’. The main window itself consists of a big figure box on the rightside, a smaller box on the lower-leftside, and some white spaces on the upper-leftside. The toolbar consist of two main buttons: ‘about’ button where you can check the version of your Airfoil-Maker and ‘file’ button where you can create, open or save your airfoils (afl files). In Airfoil-Maker, creating custom airfoils is done by inputing your airfoil’s aerodynamic characteristic together with its shape and then save it to afl files, which can be read by Plane-Maker to be used as aircraft’s lifting surface’s cross section.Īirfoil-Maker’s user interface consist of toolbar, four selection window tab, and the main window itself. As the name suggest, this program is used to create custom airfoils for further use in Plane-Maker. Reference Graph of Cm (airfoil pitching moment coefficient) vs AoA (angle of attack) at Reynolds number given in previously.Īirfoil-Maker is one of the three X-Plane’s supplemental programs. Reference Graph of Cd (airfoil’s drag coefficient) vs AoA (angle of attack) at Reynolds number given in previously. Reference Graph of Cl (airfoil’s lift coefficient) vs AoA (angle of attack) at Reynolds number given in previously. Reynolds number at which the airfoil performance is evaluated.Īirfoil’s thickness in fraction of chord length.Īirfoil’s Drag Divergence Mach number (required for high subsonic aircraft, transonic aircraft, and supersonic aircraft) It is important that you have them all completely, so, you can go through all part of this tutorial without any obstacle. it is also recommended that you understand the basic concept of airfoil aerodynamics first to make this tutorial easier for you.īefore taking further steps in this tutorial, you should prepare the items/data listed below. If you don’t have aerospace engineering background. If you don’t have it, you need to search the internet for your airfoil’s aerodynamic characteristics or obtain it yourself by using CFD software. It is also assumed that you already have your own airfoil shape and its aerodynamic characteristics (lift polar, drag polar, and moment polar, etc). This tutorial was made based on X-Plane 9’s Airfoil-Maker with Windows Vista 32 operating system. In this tutorial, it is assumed that you are using the same version of X-Plane’s Airfoil-Maker and you are familiar with basic computer file operation. In this tutorial, you will learn how to create custom airfoil for your aircraft in X-Plane by using Airfoil-Maker.
