Introduction

As first, excuse my English (if so it can be called).

This software let you manage, modify, process and print airfoils for modelling use.

If you need more information during the use of the software you can press F1.

The use of the software is very simple:

by the 'File' function of the main menu you have access to all airfoils in database.

For example if you want to print an airfoil you must:

- Press 'File' in the main menu

- Select in list the airfoil you prefer

- Press 'Begin Printing'

- Input the requested parameter and press 'OK'

- Now you can see a new window with the document you are going to print

- Press now 'Print-Print' to have the real print on paper or 'Print-Preview' to have a preview on video of the real print.

Good work and nice flies to all

Dialog window About Profili

This window shows the program version, info about copyright e how to contact me.


Dialog

Dialog window File

This Window provides the access to the airfoils in the database and manages all the relative function.

You can see a list of the airfoils filtered by name.

You must select an airfoil and press the desired function button.

Selecting an airfoil you can see the associated notes and a small preview picture.

Here are the supplied function :

Filter by name ->	Lets you to find the airfoil searching the specified text in the name. If no text is inserted, all airfoils are listed.
New airfoil	Lets you to add a new airfoil to the database.
Generate new NACA airfol	Lets yuo to create a new NACA airfoil of the mathematical series
Modify selected airfoil	Lets you to modify the coordinates and note of the selected airfoil. Changing the name a new airfoil is added to the database.
Preview selected airfoil	You can see a picture of the airfoil in a new window.
Delete selected airfoil	Delete the airfoil from the database.
Process selectef airfoil	Lets you to make transformation of the selected airfoil.
Begin printing selected airfoil	Open a new window asking parameters for the print job.
Export on file selected airfoil	Create a text file including the coordinates of the airfoil.
Exit	Close the window.

Dialog window Airfoil data

Lets you to insert a new airfoil or to modify an existing.

Changing the airfoil name this one is added to the database.

How managing tables

To quickly insert the coordinates of a new airfoil you must :

- Go in X field and edit his value

- Press Tab key to go to Y edit field

- Edit Y value

- Press Enter. X Y data will be inserted at the end of the table (like pressing 'Add') and the X field will be focused for next value.

To correct a wrong value:

- Click on the relative row in the table. The X field will be focused with the current value.

- Modify X or Y value.

- Press 'Modify'.

To insert a new row into the table (not at the end):

- Click the row where you want insert new data.

- X Y edit controls will show the relative data. Insert new data.

- Press 'Insert'.

To delete a row :

- Click on the row.

- Press 'Delete'

Rules for the coordinates introduction

You must observe these rules:

- You must enter at least tre upper and lower coordinates.

- The first X coordinate must have 0.0 value.

- The last X coordinate must have 100.0 value (this means that the X range must be normalized to 0-100).

- X coordinates must be in ascending order..

If some rule would be failed it will be signaled when you press 'OK'.

Dialog window Airfoil preview

This window shows a quick preview to evaluate the airfoil shape.


Dialog

Dialog window Processing Airfoil

This window lets you to apply sophisticated transformations to airfoils.

You can see the blue original airfoil and (after first transformation) the red new airfoil.

To process tranformation you must insert the right parameter and press 'Apply processing'.

Pressing 'OK you can now add the transformed airfoil to the database with the new name.

Supplied transformations

Thickness change:  lets you to modify the airfoil upper and lower thickness independently. You must  insert the changing percentage (from -100 to 100). A negative value will reduce the thickness.

Bending change : lets you to modify the airfoil bending. Moving the cursors you can see a preview of the bending you are going to apply, selecting the value of the bending in percent and the X point of application.

X axis stretching : lets you to stretch X axis starting from the first indicated point and carrying it to the second. For example you can increase the 'laminating' of the airfoil selecting 30 (where we suppose is the max airfoil thickness) as first value and 40 as second value. The max thickness will be translated in X from 30% to 40%. In the same way you can round the airfoil nose inserting for example 10 and 8.

Using these tranformations you can now create in a short time a lot of new airfoils.

Hoping they will work... (8- )


Dialog

Dialog window Begin printing

In thes window you can insert all the needed information for airfoil printing.

Then you must press 'OK' and  will be opened a document window ready to be printed.

You can press Print-Print from the main menu to make the hardcopy of the document or Print-Preview to check the hardcopy result on the screen.

The printing will be made with a landscape paper orientation.

If the airfoil chord is bigger then paper size, but lesser then twice, the airfoil will be splitted in two parts, with the cutting points well marked.

In this way you can print on a normal A4 paper airfoil over 50 cm.

Here is requested data:

- Chord length in mm. No explanation required.

- Draw skin. If selected will be drawn the airfoil considering also the skin thickness.

- Skin thickness. The thickness of the wing skin.

- Drawing thickness in mm. The drawing thickness for airfoil lines.

- Draw center line. If selected will be drawn the center line of the airfoil.

- Math interpolation. If selected lets, by math computing, to draw airfoils with few points in a more accurate way, adding a big number of interpoling points to those supplied.


Dialog
Generate new NACA airfoil

Lets you to create a new NACA airfoil of the series 4 digits, 5 digits, 4 digits modified, 5 digits modified, 16 and 6 (63, 64, 65, 66, 67).

More info are in the dialog.


Dialog
Dialog window Draw interpolated wing ribs

Let's you to draw all the wing ribs with different sizes and airfoils at root and tip.

In thes window you can insert all the needed information for airfoil printing.

Then you must press 'OK' and  will be opened a document window ready to be printed.

You can press Print-Print from the main menu to make the hardcopy of the document or Print-Preview to check the hardcopy result on the screen.
