is a single skin paraglider with a 5.66 aspect ratio (same as BHL3). With profiles, solutions, and details very similar to the BHL4, but with a more elongated shape in plan, and 39 panels instead of 35. An
improved substitute of the BHL2, 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 and BHL4. 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 and efficient performance single skin

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.
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.
