The sail member (3) includes a first outer envelope (8) having, in the inflated state, the shape of a geometrical solid with a substantially constant cross section shaped as an airfoil extending in a main plane (P). The first enveloppe (8) has therein a first series of stiffening membranes (9) of a flexible and substantially inextensible material, perpendicular to said main plane (P).</p> |
