is a single skin paraglider with a moderate 4.69 aspect ratio. An updated
and improved version of the BHL1 (Batlite), using the experiences
adquired with previous monosurfaces. The shape of the profile is the
same as BHL2, but with a different distribution of triangles. In this
case, we use 5 points of suspension for the profile, with the intention
to better define the trailing edge. There are two closed cells near the
wingtips with an elliptical inlet as BHL2-evo. The shape of the vault
is the same as BHL3. The list of
lines proposed initially is the one that comes out of the program,
without modify. The nose will be rigidified with two rods
(contour and vertical compresion rod). The skin tension will be
increased with a variation more pronounced between centre and extremes,
and more smooth (using a new subroutine for skin tension). Finally, the
brakes will be fixed to the trailing edge with a small "V" ribbon, to
shorten the trailing edge when braking and eliminate part of the
ovalization and creating a more defined flap. All of these details
should provide a simple, efficient and fun single skin paraglider.
Using the same solutions, but with a more elongated planform, there is

DATA FILES AND PLANS
input and output files. DXF files without editing, as they come out of
the program. This version can be built, but I recommend to wait a few days...
to complete some important details: vertical rods in the leading edge
(to increase rigidity), the new distribution of tension of skin (this
can be fundamental for the performance), nose with two 3D cuts, "V"
ribbons in brakes, and two wingtip intrados panels.
Currently, there is no prototype in construction, although there is already a german constructor interested. News soon.
LAB NOTE: Build
a paraglider at home is a
very complicated task (even simple
skin), and requires many
hours of work. Previous experience is required, and very inventive.
As always remember that:
The free flight implies risks
that can only be known and they can be controled with a suitable formation on the part of a recognized school.
Not test wings without knowing their functioning. The
construction and test of experimental wings without certifying requires
deep knowledge of what is being made.
