After
several years of development (preliminary version in 2005), Laboratori
d'envol presents in 2010 "LEparagliding 1.0" paraglider design program,
that follow the
laboratory concepts and techniques, and allows improved design for the
new
gliders. With
the help of LEparagliding 1.0
has been possible to design the gnuLAB2 paraglider in
2010.
The latest version released is LEparagliding
2.0 (january 2012), which contains many enhancements over the previous
version.
- Scale factor to design different
sizes
- Elastic
corrections in
the lines, depending on
the load
- Plans
prepared for printing on
paper (amateur use)
or for computer cutting table (professional
use).
- Design aids to facilitate the
work of sewing
- Support for the division of the sail panels in colors (testing)
- Horizontal straps
- V-ribs
(two cells without lines)
- VH-ribs
(three cells without lines, in testing)
- Rotation
of triangles in space for
single surface paragliders (choice of double or simple surface paraglider! in testing)
- In
general, better presentation of the plans, although there is
still much room for improvement
The new (2012) BarretinaHyperLite
is
designed with
this program.
However, the
use of the
program remains
"cryptic", even more than
the
previous version, but very powerful and
"easy". Thus is
only recommended for people accustomed to
work with text files containing
sorted data,
and CAD systems. No
graphical user interface, but its mode of operation does not need. Is necessary, a pre-processing of data in CAD
systems (or equivalent
analytical tools) and a CAD
post-process of the
DXF resulting files,
for printing or for the automated cutting table.
The program works by
reading some data files:
The
program reads the data, calculates and draws the glider in 2D and 3D in
a few
seconds.
The results are obtained in three files:
leparagliding.dxf
containing drawings to be interpreted and plotted with a CAD program
lep-3d.dxf
containing 3D drawings model of the glider and lines
lep-out.txt
containing the
summary of the geometric and aerodynamic parameters calculated, and the
length of all lines.
I'm still
working on several improvements!
