ABSTRACT:
A reversible aerofoil or hydrofoil has a central panel with lateral panels hinged thereto. The section of the central panel is symmetrical on either side of a central axis and the lateral panels are of similar section to each other. Either of the lateral panels can be folded in to lie against the central panel or the other lateral panel or both, while the other lateral panel is extended, the combined panels thereby forming a non-symmetrical aerofoil or hydrofoil section. By extending the folded-in lateral panel and folding in the extended one, the section is reversed.
