Niviuk N-Gravity 4 (PAST MODEL)

N-Gravity 4: Show must go on!

Power in your hands

Squeeze the energy of the new N-Gravity 4 designed by acro pilots for acro pilots. Practice and improve all kind of manoeuvres in a smooth and extremely precise way, feel all its power under your fingertips at any moment.

Undersurface air Intakes

The incorporation of valves in the undersurface facilitates vertical descent manoeuvres such as the helicopter, due to a better conservation and distribution of the wing’s inner pressure. The end result makes the N-Gravity 4 a safer, more efficient glider during the chain of aerobatic moves and recoveries.

Unlimited possibilities

Due to the integration of Nitinol material to the profile and the optimization of the suspension lines load distribution, the outcome brings a more solid, resistant and durable glider in a never ending aerobatic show. With the N-Gravity 4, the range of manoeuvres to perform is endless.

Technologies

SLE (Structured Leading Edge)

The SLE provides more rigidity and stability along the span of leading edge but also allows full flexibility along the both the vertical and horizontal axis of each open cell. The SLE ensures ease of movement on the ground and high security in the air during turbulence and whilst flying at speed.

With the SLE system there is no longer a need to use large amounts of mylar material to achieve leading edge reinforcement. This reduction in material has reduced the weight of the leading edge and the result is precise handling on the ground and easier launches.

The SLE also helps to prevent deformation of the leading edge and therefore with correct care will extend the life and efficiency of your glider.

In addition to the SLE, we work on new geometry and layout of the internal reinforcement. This new internal restructuring offers better overall cohesion of the glider and incredible stability during turbulence.

TNT (Titanium technology)

Constantly innovating, we always are on the hunt, looking for the latest and best materials to helps us design optimal products. For this reason, and after an extensive evaluation of its benefits and qualities, we decided to be the first manufacturer to use Nitinol in our glider line.

Benefits

Nitinol is an alloy of 50% nickel and 50% titanium. This technology in our rods offers three major advantages of optimizing the performance of a paraglider, compared to those made out of Nylon:

• The addition of Nitinol rods in the profile has the immediate result of substantially reducing the overall weight of the wing by about 13%. 
• Nitinol has two very specific properties: shape memory and super elasticity. The flexible rods always regain their functional optimal shape, even after tight bending, no wrinkles or residual mechanical alterations affect their integrity.
• As a result, the wing's leading edge is then preformed on the ground and allows a uniform progressive inflation phase to take place, which considerably facilitates the take-off. The wing surface is perfectly taut, wrinkle free and without parasitic cloth movements, the glide is thus optimized in all flight phases.

In addition, the rods are outfitted with plastic protectors at their ends to prevent fabric damage.

3DL (3D Leading Edge)

Adding an extra seam to the leading edge on the span axis of the glider helps to shape a compact 3D profile and have better connections to the new 3DP front panel’s layout.

When sewn together, the fabric pattern orientation and panel positioning are taken into account to avoid creases and ultimately obtain a perfect load distribution. As a result the glider profile is cleaner, to the benefit of performance and durability.

The application of this innovation to the profile is key to reaching the perfect shape from 2D to 3D.

3DP (3D Pattern Cut Optimisation)

Our paragliding and paramotor wing designs have changed significantly over time; hence considerably affecting the leading edge shape.

The latest glider generation requires a new pattern design and an optimized fabric cutting process.

The new leading edge arrangement calls for each cell panel to be manufactured independently from the others according to the final wing layout positioning, resulting in a crease-free surface with better fabric tension. We could use the analogy of a rugby ball made of different sewn individually shaped panels to obtain the perfect characteristic oval shape without wrinkles.

An optimised process is used to cut the fabric in a specific directional angle, depending on each panel’s final location. If the cloth pattern is correctly aligned with the load axis, the material is deformed to a minor degree to benefit the aerodynamic properties of the leading edge.

The application of this innovation, together with the 3DL, is key for reaching the optimal modelled form and function from 2D to 3D.
