Libra RS

• RAST; On paragliders with RAST the canopy is divided into different internal pressurised sections by one or more fabric panels, some with valves running crossways to the direction of flight. This makes it possible to influence the air flows within the canopy.

With RAST, the air equalisation flows within the paraglider canopy can be regulated through defined openings. This applies both when filling,(during take-off) and when emptying. In the case of pressure loss, e.g. caused by canopy collapse in turbulent air, the relative internal pressure of the CORE section increases, while the BUFFER section absorbs the introduced energy by deformation. Furthermore, RAST can be used as an additional support to the leading and trailing edge, which has a positive effect on flight comfort. As RAST connects the ribs over the entire profile height, the construction has a stiffening effect and reinforcements and/or stiffening elements can be saved or even completely replaced by this special construction method.

• Nitinol Wires; Nitinol is a shape memory alloy that is highly durable, temperature-resistant, and corrosion- resistant. The name Nitinol is an acronym derived from its composition of Nickel and Titanium and its development at the Naval Ordnance Laboratory. This material is widely used in medical technology, and Swing has been one of the pioneering paraglider manufacturers to use Nitinol as leading edge reinforcement.

The use of Nitinol reinforcements in the LIBRA RS ensures a consistently sharp leading edge and maximum profile fidelity. The stiffeners located in the top and bottom sail are also made of this shape memory alloy, which is resistant to buckling, temperature changes, and moisture. You can rest assured that the performance of the LIBRA RS will not be affected by any unwanted deformation of the canopy, even if it was not packed or stored optimally.

• Risers; The LIBRA RS riser features two main risers, each of which is divided. The split A-riser makes it easier to put on and take off your ears, while the BIII-trunk line is separately suspended through a run-through system, which provides:

A more stable outer wing during accelerated flight.
More effective pitch control through the rear risers.

This is accomplished by the differentiation of the outer B-stem line, which causes the BIII to convert only half of the input during both acceleration and when pulling on the B-risers. The ergonomically shaped T-bar, designed specifically for the LIBRA RS, enables maximum control of the canopy through the rear risers and can be easily disassembled if needed.

• Big Ears; “Big ears” are easily executed with the LIBRA RS, both at trim speed and full speed, even in turbulent conditions. To apply the ears stably and effectively, our development team recommends first taking half a wrap (from the original factory setting of the brake master line!) to bring the brakes slightly under tension. With the shortened brake line in your hand, reach above the connection loop into the separately suspended outer A-stem line (AIII) and pull it down.

• Shark-nose; To increase the internal pressure of the profile in the front area of the LIBRA RS at low angles of attack, a nitinol-reinforced shark-nose adapted to the profile ensures optimum stability at high speeds.

• Pro Dry Aramid Lines; The latest generation of unsheathed aramid lines are used in the LIBRA RS. The special Pro-Dry coating, reduces the line’s moisture absorption by 60% and increases its UV and dirt resistance. The magenta, blue, and orange colouring of the lines makes them easily visible and easy to sort without a sheath. The high stiffness of the line material also reduces knot formation in use.

• Airflow Alignment; The profile of the LIBRA RS is based on the high-performance profile specially developed for the SPHERA RS. The profile features double 3D shaping in the area of the profile nose to reduce wrinkles. The individual ribs are aligned from the centre of the wing outward in the direction of the airflow. This achieves maximum aerodynamic quality of the profile, which is continued to the trailing edge through the additional use of mini-ribs.
