Wing with variable configuration

THE CORSET The current state of technology 1/ Responsiveness in roll of fixed geometry flexwing depends on the wing’s flight speed, which is sluggish at slow speeds and jittery at high speeds. For modern machines with a wide speed range this leads to very poor maneuverability at low speeds that prohibits practical operation, and leads to hypersensitivity in roll at high speeds making control difficult, or even dangerous. In addition, low speed approaches are not recommended. In practice fast wings are unable to make slow approaches and land in a short distance, especially in turbulent...

Innovation THE CORSET In action Slow speeds : Approach and landing The billow of the wing is very high, allowing for significant differential movements and providing the best handling roll. Twisting of the wing tips is also at maximum, the central part of the wing stalls first to ensure safe and predictable handling in large angles. The central profile is concave, providing the best ratio of lift and ensuring the lowest possible minimum speed. The increase in the billow and twisting increases drag, which is favorable under conditions of steep approach. Tension released : Twisting wing tip,...

High speeds : Trips, Navigation, strong wind Tension increased : Increased twisting in general Decreased prominence of central profile Increased central reflex Billow decreased Center of thrust retracted. This configuration creates : Reduced drag Effortlessness in low pitch, roll stability AND increased speed cruise The billow is very low, providing perfect stability without the commitment of roll movement. Twisting of the wing tips is minimal, providing the best aerodynamic performance of low angles. The central profile is relaxed, ensuring the preservation of perfect pitch stability...
