The ailerons, moving in fluids (water, air) and receiving the thrust of these fluids sometimes on one face and sometimes on the other, have to be able to form a concave-convex profile which is self-deformably reversible. They are constituted by: - a non-deformable solid construction 1 forming the framework of the aileron; - a deformable part 2 connected in a sealed manner to this framework; - a fluid 3 for filling the movable volume left between the framework and the sides of the aileron. The initial shape 4 is symmetric and pisciform. The shape adopted by the aileron when working in the fluid is imparted to the construction by the concave curvature 5 of the rigid part of the aileron. These ailerons find uses in fields concerning airborne and marine vehicles, such as aerofoils, wings, propellers, keels, centreboards, rudder blades (anti-rolling fins), control surfaces, etc.
