2 PARATECH Technology
2.1 Computer Aided Design
In order to develop the pattern for the P43 canopy we used a variety of C omputer-
A ided- D esign software. The fabric is cut with highest precision by a computerized
cutting machine.
2.2 Shape of Canopy
The P43 is captivating with its elegant and esthetic shape and at the same time main-
taining a high aerodynamic quality and passive safety.
2.3 Airfoil
The P43’s airfoil was researched and refined by PARATECH in intensive and in-
volved calculations and test flights. Different airfoils spread over the total canopy op-
timize the lift. This is the reason for a balanced combination of performance and sta-
bility.
2.4 Cell Opening with PAF (Permanent Air Flow)
We named our newly developed geometric zigzag design of the cell opening PAF ,
short for ’’ P ermanent A ir F low’’ .It consists of a consecutive development of partially
closed cells. This allows for a even, quick and dependable inflation at any angle by
smallest cell opening. This explains the extremely easy launching by high trimspeed
of the P43.
2.5 Reinforcement
Careful design of the reinforced areas of the P43 takes care of the strength at critical
points while permitting easy inflation at launch and quick reinflation from collapses
due to turbulence.
2.6 Diagonal tapes
Diagonal ribs were also used for the P43. The extreme light construction makes it
possible to have fewer hang points at a high cell number, great aerodynamic quality
and lowest canopy weight. The diagonal ribs have a big influence on the performance
potential and the aesthetic of the P43.
