A SOURCE OF INFORMATION FOR AEROMODELERS
If you are looking for an airfoil plotting program for your Macintosh or
Windows PC, or "helpers" for CAD applications (either Mac or Windows),
try these links:
FOR THE MACINTOSH OS
CADintosh is a shareware 2D CAD program for technical and architectural
drawings from Lemke Software. A recent update allows direct importing
of airfoil sections from Selig and Eppler coordinate files as
downloaded from the UIUC web site. Once imported into CADintosh, the
section drawing can be exported as an HPGL or DXF file. Works great,
and separate CADintosh applications are available for older 68K Macs
and newer PPC machines. The shareware fee is US$32.00.
Foil 1.2 is the last version of Gregory Payne's airfoil plotting program
for the Macintosh. Foil 1.2 plots high resolution airfoils from text files,
allows section comparisons, and can create coordinate tables from scanned
airfoil images. (Foil 1.2 is free but not public domain.) If you are downloading
Foil 1.2 from the above link, you will be getting the entire Foil 1.2 file
which includes a large collection of airfoils and a test image for software
Foil Coordinates to MiniCAD 3
This is a small HyperCard stack which rapidly translates airfoil coordinates
into MiniCAD 3 polygons. Written by John Clark of Australia. Foil Coordinates
to MiniCAD 3 requires both HyperCard Player and of course MiniCAD 3. A
sample translation (EH 1.0/7.0) is provided on the first card.
J-Foil 0.1, written by Doug Hoffman, is a tool for creating high quality
airfoil plots using the Macintosh computer and a printer. Skin thickness
adjustments can be made, thus producing rib plots. (J-Foil 0.1 is free
but not public domain.)
Dave Johnson's MacFoil not only plots airfoils, it can draw template
sheeting allowances, reference lines, and up to ten spars. MacFoil also
allows you to change airfoil thickness and camber, add washout/washin
a template, and export airfoil data to a text file. Coordinates are
in UIUC format, and MacFoil reads any airfoil coordinate file written
that format. MacFoil
1.5 runs on Macs using OS 8.6 or OS 9 with CarbonLib installed, or OS
X. This download is from our archives as the original MacFoil 1.5 download site is no longer active.
Anders Lennartsson, of Stockholm Sweden, has ported Shamim Mohamed's Plotfoil
3.3 to the Mac! This is Anders' second port, the first being Plotfoil 3.2.
Plotfoil 3.3 for the Mac does not at this time include all of the original
Plotfoil 3.2 features, like the prompt mode, but it is otherwise fully
functional, including mixfoil and editfoil. Plotfoil 3.3 for the Mac requires
a PostScript® printer. (Plotfoil 3.3 is distributed under the GNU General
FOR THE MACINTOSH AND THE PC
Chipmunk Basic is an old fashioned Basic interpreter which runs on all
Macs and which is also accelerated for PowerMacs. Features supported include
AppleScript, Drag&Drop, graphics, sprites, sound, speech and object
oriented programming. Runs on systems from 6.0.7 thru MacOS X, Mac 512Ke
thru the latest Apple G3 and G4 PowerPC desktopMacs and PowerBooks. There
are also Chipmunk Basic versions for the PC environment - Windows98/NT/Me/2000,
SunOS/Solaris and Linux (Intel/x86). Chipmunk Basic is copyrighted freeware.
You can download Chipmunk Basic, manuals, and sample programs from the
FOR THE PC/WINDOWS ENVIRONMENT
AirFoil Viewer V1.3
Hubertus von Heynitz wrote AirFoil Viewer V1.3 as a relatively simple on-screen
airfoil plotter. AirFoil Viewer V1.3 runs on Windows machines as an EXE
file. Despite its simplicity, it does have a number of features, including
scaling (1:1, 2:1, 3:1, and 4:1), the option of a superimposed grid, upper
and lower surface maxes, plotted meanline, and editable coordinates. AirFoil
Viewer V1.3 can print the resulting plots, and can also write AutoCAD SCR
files. A good sized clock in the upper left corner is a useful accent.
Eric Sanders' Compufoil is by far the most popular of the airfoil plotters
for the Windows environment. CompuFoil is a modular application, so you
need buy only the part(s) you need. The CompuFoil site has a demo version
of the software, a tutorial on foam cutting, pictures of 'planes built
using CompuFoil software, and of course complete ordering information.
John Dreese has written an application related to airfoil design. DesignFOIL
is built on DreeseCode’s SNACK technology and is the easy way to design
airfoils. DesignFOILhas a creation engine for NACA airfoils,
flap-bender/aileron-maker, and virtual wind tunnel, and it can plot
airfoils up to four feet wide and ten feet long. DesignFOIL includes
WingCrafter and Gridgen and CMARC export. Visit the DesignFOIL page and
download the demo!
Sandro Fergnani submitted rfile to us for posting here on our web site.
Rfile takes a file with airfoil coordinates, as available on the UIUC site,
and produces another ASCII file that contains: 1) the airfoil described
in segments; 2) the moment coefficient, Cm0; 3) the zero lift
angle of the airfoil; 4) the mean line described by points. Written in
C, rfile is a DOS program which will run in the Windows DOS shell. There
is no user interface, as none is needed. Documentation
is also included within the rfile folder.
