An aerofoil has at least one space frame and at least one pre-stressed cover supported by the space frame. The space frame has one or more structural members, the structural members including a structural foam material; and the pre-stressed cover forms at least a part of an external aerodynamic surface of the aerofoil.

    La présente invention concerne une surface portante qui comporte au moins une structure spatiale et au moins un revêtement précontraint supporté par la structure spatiale. La structure spatiale comporte un ou plusieurs éléments structuraux, les éléments structuraux comprenant un matériau structurel en mousse ; et le revêtement précontraint forme au moins une partie d'une surface aérodynamique externe de la surface portante.
