Ailerons having self-deforming reversible profiles. Dumortier Paul, March 27, 1987: FR2587675-A1 (9 worldwide citation)

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 fr ...
