Abstract: A device for simultaneously and progressively varying the camber and the angle of attack of a hydrodynamic and aerodynamic profile of a wing, the latter being able to adopt multiple positions including a position at rest, the said profile at rest being in a plane, the device having a wing with a profile having a leading edge at the front and a trailing edge at the rear, a seat arranged in the upper part of the profile of the wing connected at one of its ends to the front upper part of the profile by a first pivot, and at its other end to a lever by a connection point, a lever connected to the rear upper part of the profile by a second pivot, and that at rest, a seat and at least one lever are aligned or substantially aligned along the same axis and are included in the same plane as the profile.
