PPN description
2 systems, one purpose:
Highest safety by AFS and PPN
The U-Turn FREE FORCE 3 opens a new safety chapter in paragliding: The combination of the PPN sys-
tem (Precision Profi le Nose) with the unique system of automatic fl ight stabilization (AFS) takes care for
the so far unreached resistance against collapses.
The U-Turn FREE FORCE 3 defi nes the new safety standart in the DHV/LTF 1-2 gliders.
PPN technology provides unprecedented stability, superior take of behavior, and ideal fl ying qualities.
For several years, now synthetic rods have served as a replacement to the Mylar panels in the cell walls
of the wing at the leading edge. This reinforce the shape of the nose. U-Turn has taken this a step further
in teaming this technology up with AFS and work togehter in concert.
The synthetic rods in the seams of the leading edge sustain the shape of the nose, optimizing the airfl ow
along the profi le. Even under extreme fl ying conditions the small PPN rods keep the cells at the leading
edge open in a way Mylar would not be able to do. These characteristics give the glider an unmatched-
stability. Internal pressure is maintained noticeably longer and the shape of the nose is held up. Even
if the internal pressure diminishes, the AFS kicks in by equalizing with the providing the necessary sail
tension. The complimentary interaction of these two systems provide this line of gliders with an unpar-
alleled collapse-resistance.
Unlike Mylar, if handled carefully PPN technology will retain the shape of the nose for the entire lifetime
of the glider. In order to provide the greatest possible protection when folding the glider, U-Turn recom-
mends the optional U-Turn Tubebag. This inner packsack enables you to fold and store the FREE FORCE 3
with ease in accordion fold, even on windy days and/or by yourself. The Tubebag preserves the excellent
take-off and fl ight qualities of the glider, thus favorably infl uencing its resale value. PPN technology also
means that the canopy is lighter weight than with Mylar reinforcement. This reduced canopy weight
made possible by the PPN technology increases the performance and improves the handling of the
glider. The Tubebag itself is produced with the workmanship you would expect from U-Turn and lives
up to the highest demands in use. It features many functional details and ensures that the FREE FORCE 3
preserves the launch and fl ight qualities for many years to come - an advantage that can increase the
resale value.The glider has become lighter ever since abandoning the use of Mylar in the cell openings
and replacing them with synthetic rods. Its handling advantages and increased performance can be
also attributed to PPN technology.
