Aircraft with active control of the warping of its wings. According to the invention at the outer end (10) of each wing of the aircraft is articulated an additional aerodynamic plane (14) swept back with respect to said wing. The pivoting of said plane (14) is controlled in such a way that at at least certain flight points of said aircraft the aerodynamic forces engendered by said plane (14) modify the reference warp of the wing into an aerodynamically optimal warp for the relevant flight point.

Why it's free to use
- Filed May 2, 2003 and granted January 10, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 2, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 2, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
