Vela configurable rigid profile.

Configurable rigid sail profile. Formed by a rigid structure (2) of tapered section, comprising two opposite lateral convex and rigid walls (3, 4) defining an interior space (7). It comprises elastic blades (13, 14) enclosing, together with the corresponding wall in at least one zone; a closed outer spaces (23, 24) of variable volume defined between each lateral rigid wall (3, 4) and each elastic blade (13, 14); multiple perforations (8) provided in the rigid walls (3, 4); means for generating and feeding compressed air to blow air at the outer enclosed spaces (23, 24) through said perforations (8) in order to inflate said elastic sheets (13, 14), increasing the volume of the spaces Outside closed; and means for generating and feeding vacuum to the vacuum in said outer enclosed spaces (23, 24) through said perforations (8) in order to deflate said elastic sheets (13, 14), reducing the volume of Outside enclosed spaces.
