gets to enjoy the benefits of an entirely
new aerofoil.
The aerofoil is nothing less than the next
generation of the Hybrid Synergy Aerofoil.
The basic premise for this design concept
is to combine the characteristics of a
competition wing aerofoil with that of an
intermediate wing
– and the child of this
union is a unique new Aerofoil with the
best of both worlds. The Summit XC² has
the performance of a competition wing and
the safety of an intermediate glider!
The best of both worlds
– basic gliders
and comp glider
– a new design with the
following advantages:

perfect performance

optimal safety

high-performance feel

accurate handling
Airfoil Stabilising System²
UP was first with the Aerofoil Stabilising
System, an idea that has since been
widely accepted in the industry. The
Summit XC² uses a modified version of
the same, and we have chosen to call this
the ASS². Instead of Mylar® the ASS²
comprises a Nylon® batten that defines
the leading edge curvature and helps
keeping the cell opening open at all times.
This Nylon® batten is insusceptible to
bending damage and has no ageing
properties
– it will normally outlast the rest
of the canopy by a good margin. This
means that the UP Summir XC² will retain
its perfect launching characteristics all
through its service life. In the unlikely
event that a batten should break it can
be replaced in a few easy steps
–
please refer to the chapter “Replacing
ASS battens” for guidelines.
Performance data
Main focus area during the
development phase of the Summit XC²
was the improvement of the key
performance figures in comparison to
the predecessor. We wanted a wing
with higher trim speed and better L/D
at all speeds, and through the use of
advanced software we could begin to
compare on the virtual 3D models right
from the outset of the drawing process.
Combining different software allowed
us to draw a wing that at least in the
virtual world was significantly better,
and the real-life refinement and testing
showed that the computer models
were right.
Canopy material
The UP Summit XC² is constructed
from polyamide cloth, which is
particularly stretch-resistant and
durable, and is specially treated for
maximum UV resistance.
After At UP we are always testing new
materials to see if our wings can
benefit from new developments in the
textile industry. After comprehensive
tests we have settled on the following
Porcher Marine material mix for the
Summit XC²:

Leading edge top: 9092 E17
"Evolution Plus" (45 g/m²)

Bottom sail and trailing edge:
9017 E38, (40 g/m²)
