The ETERNITY is a middle A glider with optimized performance weight. The light wing is of-
fering an enormous safety cushion with a sportive handling. That turns him into a perfect
all-round talent for every adventure. Not only beginners will enjoy the ETERNITY - the mistake
forgiving behavior will definitely bring sustainable flight fun for ambitioned XC pilots and alpin-
ists as well.
The new LTF A class wing was designed under the hard criteria of uncompromising passive
safety and still the exact handling should not be cut short. Therefore the ETERNITY offers an
easy start for students when first flying high, as well as extended fun moments for experienced
pilots. The ETERNITY transforms control pulses precisely and combines A class appropriate
tolerance with dynamics. The sweet-tempered flying behavior is encouraged through the light
weight of the canopy among other things. The reactions are therefore subdued accordingly. The
markedly outstanding glide- and rise ability is especially coming into effect in weak thermal lift
and efficiently turns that into height. During the development especially much attention was
paid to an easy start behavior. Through a multitude of constructive optimizations these were
perfected. Particularly in difficult conditions the ETERNITY simplifies the start to every pilot.
The light canopy rises reliably, even at zero wind with little effort required, over the pilot. Ad-
ditionally the exceptional slow flight features of the wing are causing a low take off speed and
much control time during the start.
The ETERNITY is based on the newest knowledge of the flow simulation. Chief designer Ernst
Strobl developed a wing profile that combines a high tolerance spectrum with glide features
full of buoyancy. Elaborate calculations of the High Pressure Crossport Design (DPCD) are
not only providing the weight reduction but are also maximizing the transverse aeration of the
cross ports. How efficiently this system works, is already manifested while the glider is rising.
It provides a very fast pressure build up and gives the wing a balanced internal pressure during
the flight. The 3D shaping and the optimized pre-tensioning of the wing as well as the Precision
Profile Nose System (PPN) are enabling the perfect flow around the profile. Mini-ribs and the
Brake Gathering System (BGS) are helping the profile to more form fidelity at the rear end and
precisely transfer the control pulses to the wing. A very overseeable line concept with few main
lines is providing an easy handling and a good overview during ground handling. The risers are
equipped with the Pilot Assistant (PAS) where besides the color coding, icons are offering a
better orientation on the line levels.
In the material mix also only high tech materials which meet the high expectation of the long
term endurance were used. So selectively used material strengths of the top materials Dokdo
30 and 20 as well as Skytex 27 offer the optimized performance weight with very high durability
and form fidelity. The used light material with double coating is clearly superior in the matter of
porosity in comparison to heavy materials. That is now also confirmed by long term results and
disproves the myth according to which heavier materials achieve better check results.
The ETERNITY offers safety with optimized performance weight. It is not only aimed at begin-
ners, who want to start with small pack size and little weight, but the modern wing also guar-
antees sustainable fun for ambitioned pilots. The size XL additionally has the tandem certifi-
cation and therefore offers a light alternative for the double flight fun with matchless direct
handling.
