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.
