Wing Designer

Most airfoil programs are based on the construction of individual airfoils or tapered wings. The STEP-FOUR WING designer, enables you to build complex wings, including spars, joiners, leading and trailing edges, the sheeting, rudder flaps and fixture supports, etc., interactively on your computer screen. Simply click on your choice of airfoil in the airfoil data base provided, which contains a fantastic selection of more than 1100 airfoils.

The WING designer has an impressive range of features enabling you to design aerodynamic wings using any geometric data quickly and efficiently. When developing the program, STEP-FOUR made sure that the WING designer could be used by model builders at once, including those who have no experience with CAD programs.

Several windows provide views not only of the top view of the wing but from every angle. You use the mouse to click on the spars, rudder flaps, sheeting and joiners so as to make sure these are located correctly. At a glance you can see if everything is perfect or if there is still a construction error. You notice immediately, for example, if a spar joiner or maybe even the sheeting is perforated. In a 3-D window it is also possible to rotate and move the wing inside a 3-D window anyway you like. As a result you always know exactly what the wing will look like in when it is finished.

The WING designer package includes a database with more than 1100 wing airfoils. In addition, for those of you who want to use your own airfoils, there is a powerful airfoil editor with which you can enter and edit airfoils using tables or graphs. In the event of an airfoil without any coordinates, you can scan it and load it as an image in the background with the airfoil editor, and then vector it easily and quickly.

The WING designer is not only a comfortable construction tool, but also allows designs to be output professionally. If you have a plotter or large-scale printer, drawings can be output directly 1:1. If you only have an A3 or A4 printer, the drawing is split up into several sheets that can be joined up into one large, complete drawing. This is really easy, as the WING designer printouts are clearly marked to show where the sheets are to be joined up. In addition to the top view, set of ribs, front or side view, you can even output the sheeting and the leading and trailing edges separately. This makes it very easy to transfer the components to the actual material.

In the case of special designs, the data can be output in a DXF format for processing in CAD programs. Model builders who already own a STEP-FOUR CNC milling or cutting machine really have an easy time, since special export modules are available that generate files directly in the correct format for the machine concerned. These export modules refer to the same basic data. In other words, simply press a button and the wing can be produced as a conventional rib construction or in the form of a foam core wing.
