Swept wings set-up:

when dealing with swept wings is the same as dealing with tapered wings, a small mistake is in input field dihedral should be sweep and V-from should be dihedral. So don't get confused.

The drawings shown below will make things clear.

Here are two samples of wings where the above is a normal tapered wing and as the other is backward swept . When you enter the data for both wings the method is the same the program make no exemption in how to enter the data in both cases sweep is given as measured from the leading edge to the top-line of the wing.

When you design a heavily backward swept wing be sure that the movement of the sledges is taken in your calculation. The movement is the product of your design. If you would project a line on top of the leading-edge and a line on the trailing-edge the cutting points on the sledges will be the travel .

Parameters that are not in this drawing are the dihedral and warp or incidence these parameters you can find in the task geometry from the wing input

screen.

This figure on the left side is an example how it not should be you would get problem when you try to drive the sledges in starting position in the wing cutting screen . be sure that the movements of the sledges . there is an over travel protection on the machine but it will not warn you for this. You could see in preview in the cutting screen by clicking the max-values button if the movements are within the range of the sledges.

Triple taper wing

In this screen all the parameters are stored for a wing.

The software is capable of cutting a triple tape wing in one run but I do not recommend this .

This feature was added after a customers query if it was possible well it was possible.

it is useful for wings with not much span. It is better to design the wing at front.

Here in the picture below I have a sample from a multiple taper wing . with in-transitions from e211

to e 392 and from e392 in s7003 ( a tip left from 8 cm sanded smoothly )

part 1 part 2 part 3

when you analyze this data there are three parts or panels..

panel 1 e211 240 mm root-cord to e211 200 mm tip-cord 1000 mm long

panel 2 e211 200 mm root-cord to e392 155 mm tip-cord 850 mm long

panel 3 e392 155 mm root-cord to s7003 100 mm tip-cord 350 mm long ( panel cut at 430 mm)

now you give your three parts a name e.g. panel 1 = wcroot.tp1 panel 2 = wcmidd.tp1

panel 3 = wctip.tp1

now you put this data in the right fields.

To cut this wing you must separately load the data before cutting or you can do this in the field

trapeze 3 in the wing definition screen. Here you can input the date for a triple taper (trapeze) wing.
 

this window shows a triple trapeze or tapered wing for a glider called Witchcraft .

under the task bar button geometry you'll find a sub menu where you can independently fill in sheet thickness at a transition point . This is to compensate for the wire burn . at the narrower side of the panel the wire will cut a wider channel . by choosing a thicker sheeting the offset will be bigger . In this way you avoid to burn away to much "flesh" from the core.

You will have to do this by experimenting. You can use the notepad feature as the yellow sticky notes.
