During construction of the ANNAPURNA, chief designer Ernst Strobl focused on simplification through innovative construction features. The 3D-shaping and elaborate calculations of the ballooning combined with the optimized pre-tensioning of the wing, provide the ideal flow around the profile. The Precision Profile Nose System (PPN) helps to provide the optimized flow alongside the whole cell opening area. Miniribs and the Brake Gathering System (BGS) are transmitting control pulses to the wing with high efficiency and precision. The elaborate calculations of the High Pressure Crossport Design (HPCD) are not only providing optimized performance weight, but also maximize the lateral aeration of the crossports. A very well-structured line concept with few main lines provides easy handling and a good overview during the launch. The risers are equipped with the Multiple Speed System (MSS) and through a second pulley the accelerator travel can be shortened and thereby the glider can be turned into a LTF-A Hike&Fly wing that is suitable for training.
An intelligent material mix provides more durability with reduced weight. A high value was set on the lasting construction to keep the good flying features for everyday life. Again the comprehensive empirical values of the EVEREST came in handy. Established long term durability was also the main focus for choosing the material configuration. The used lightweight material Dokdo 10D is coated on both sides and isn‘t only the lightest material on the marked, but also exceeds conventional materials in regards of porosity. To avoid additional seams, the design on the bottom sail was completely forwent.
