The blade is composed of an outer surface and an inner spar. The thickness of the outside surface linearly decreases from 0.1 m at the root to 0.005 m at the tip. The spar has a similar thickness behavior with 0.1 m at its closest point to the root and 0.03 m at the tip. To sum up, here are the thickness specifications needed along with their location with respect to the global coordinate system (which represents the center of an imaginary hub).
