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.
