Claim Text:
1. An airfoil shaped body with a leading edge and a trailing edge extending along a longitudinal direction of the airfoil shaped body and defining a profile chord, the airfoil shaped body having a suction side and a pressure side, both of which extend between the leading edge and the trailing edge, the airfoil shaped body comprising: an airfoil shaped facing that forms an outer surface of the airfoil shaped body and surrounds an internal volume of the airfoil shaped body, at least one reinforcing member that is connected to the airfoil shaped facing with a first connection inside the internal volume only adjacent a first side of the airfoil shaped body, the first side being one of the suction side and the pressure side, and extends transversal to the longitudinal direction of the airfoil shaped body; and a distance member that is in contact with airfoil shaped facing, at a substantially flat part of the airfoil shaped facing inside the internal volume of the airfoil shaped body at a same side of the profile chord as the first connection, and at a lateral distance from the first connection and extends from the airfoil shaped facing and into the internal volume of the body, wherein the at least one reinforcing member is in contact with the distance member at a second connection at a distance from the airfoil shaped facing inside the internal volume of and only adjacent the first side of the airfoil shaped body and operates in tension for reinforcing the airfoil shaped facing against inward deflections, and the at least one reinforcing member is further connected to the airfoil shaped facing with a third connection only adjacent the first side of the airfoil shaped body and at a side of the distance member opposite the first connection and on a same side of the profile chord as the connection of the distance member to the airfoil shaped facing.
