Ikuma 3

RSD (Radial Sliced Diagonal) technology is a reinvention of the wing's internal structure. It incorporates independent and efficiently oriented diagonal ribs, which follow the direction of the cloth. This improves the strength, reduces weight and minimises deformation.

These days, in order to improve stress distribution and reduce the number of attachment points and lines, most wings have these diagonal ribs, which are connected from the attachment points to the adjacent profiles.

In conventional diagonal ribs, loading and unloading cycles away from the highest strength axis of the cloth result in a loss of shape, which reduces the cohesion of the wing and therefore aerodynamic efficiency.

Nitinol is a combination of 50% nickel and 50% titanium. The incorporation of Nitinol rods in the profile increases the performance of the wing, especially in three areas: 

- Compared to nylon rods, the weight of the wing is reduced by 13%.

- Nitinol has two essential characteristics: shape memory and enormous elasticity. As a result, the rods retain their optimum shape even after an ultra-compact or incorrect folding, so that the wing is not deformed. This will always be the case unless the radius at the point of curvature is less than 1 cm.

- The leading edge shape is much more rigid and uniform which results in a much more consistent and progressive inflation and therefore an easier take off. The profile is taut at all times, without creases, and fully optimised for all flight phases. 

In addition, the rods have a plastic protector at their ends to prevent any damage to the fabric of the wing. 

Nitinol is now featured in all our wings.

The IKS (Interlock System) is a system to connect the risers with different parts of the wing, such as the lines, the harness or the parachute. This technology stands out for its innovation in lightness, optimising both the glider and the equipment in general, without compromising efficiency or the level of safety. 

Niviuk has developed three variants: the IKS 1000, the Easy IKS 2500 and the IKS 3000, each intended to connect different parts of the paraglider.

✓ IKS 1000: risers to lines
The IKS 1000 is designed to connect risers to the lines. It can carry up to 1055 kg, which is far more than the 550 kg of the classic 3 mm maillons, but weighs much less. This makes it an essential part of our entire range of P Series (plume/light) wings, which already come with this technology as standard.

✓ Easy IKS 2500: risers to harness
The Easy IKS 2500 is a lightweight attachment system designed to connect the risers to the harness. It can carry up to 2673 kg and is made of Dyneema, making it very strong and durable. It is the perfect ultra-lightweight alternative to the twist-lock aluminium carabiner (with a maximum load of 2000 kg). The design and application of this connector makes it ideal for mountain harnesses and wings, and light flying gear.
