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.
