================================================================================
Airfoil generator utilizing the Joukowski transformation
Written by: Russell Leighton

Any comments? Just leave me a message on the Lighthouse BBS,
(805) 272-1812 (my user name is under Russ Leighton) or write to
me at the address above.
This program was mostly an exercise in C programming using the
intuition and graphics routines found in the ROM kernal. It
should, at least, serve as a fairly good example of how to use
these routines especially in combination (not as straight forward
as the manuals imply).
The program was compiled using the MANX Aztec C compiler version
3.40a. The following lines show the command sequence I used.
cc airfoil.c
ln -v airfoil.o -lm -lc
This program is free to do with as you please as long as you give
me a little credit if you use the transformation algorithms. Also,
if you make any improvements or additions please let me know about
them. Please include this documentation with the program if you
choose to give it to anyone else.
================================================================================
This program generates airfoils as well as their corresponding
streamline and pressure distributions. The equations used are
described in airfoil.doc. To use this program first run it
(either by selecting its' icon or typing "run airfoil" at the CLI
prompt) then bring up the requester by double clicking the right
mouse button (the menu button). This requester can be brought up
at any time (even during plotting) by double clicking the right
mouse button. The requester gadgets are located and described as
follows.
Gadget Location Description
------ -------- -----------

Airfoil Below ShowTitle gadget Toggles streamline/pressure plot
Camber Below Airfoil gadget Mid-chord camber entry
Thickness Below Camber gadget Mid-chord thickness entry
Angle Below Thickness gadget Angle of attack entry
Velocity Bottom edge Slider for velocity entry
