1. DESCRIPTION BHL5-16 SA is the BHL5 single skin
prototype made by Tim Weber in Sauerland, Germany. Completed in
" Here are a few more information
about my proto from the BHL5. I used Skytex 27/g m2 for the cells
and triple kite ripstop 51g/m2 for the ribs. The Lines are Liros DC (Dyneema
coated) 60 for the upper gallery 160 middle gallery 200 for the
main lines. 2,4 mm nylon rods from the garden
strore for weedeater 10mm wide belts for the line
attachment points . The line attachment points are
reinforced with self adhesive cordura 170g/m2. The yarn is Serafil S80 and i used
almost 1500m of it My versoin of the proto has the
name - LIMETTI - Without lines it weights 1605 g and
with the lines 1850g The trailing edge is reinforced
with 65g/m2 25mm wide ripstop and the leading edge is reinforced
with 1mm aramide chord."
PLANS AND ADJUSTEMENT NOTES Tim's prototype has been built according to the plans BHL5
The first flights are done usin a calage of 30%. Later, and according
to my suggestions, Tim did some experiments modifying the risers
For example, to change from 30% to 42% it is necessary extend riser A in 5.9 cm extend riser B 4.1 cm, extend
riser C 2.4 cm, riser D unchanged.
Finally, the adjustment made by Tim is as follows (june 2022):
" I decided to try it with the A riseres at 50cm
I dont know how to do the maths and how many percent calage this is :D But it flies really good. its a lot faster than the 42% and i think a little bit more stable that the 30%. It has no tendence to stall while groundhandling and i managed to soar the wing at 35kph wind :D "
Based on Tim's experimental adjustments we can deduce that his current
calage is 36%, as can be verified in the calage variation tables
generated by the LEP program:
thanks to Tim Weber for sharing the details of his project!
LAB NOTE: Builda paragliderat home is avery complicated task (even simple
skin), and requiresmany
hours of work. Previous experience is required,andvery inventive.As alwaysremember 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.
