Description
Chengchen Shentu and co-authors redesigned a lifting-wing quadrotor drone in 2026 so its wing can tilt independently of the body, freeing the wing to sit at its best angle at any speed. On fixed designs, body pitch and wing angle are locked together, wasting lift. Their tilting wing adds only about two hundred grams, driven by two small actuators.
Wind simulations showed the freed wing recovers a strong suction peak and cuts rotor interference. Flight tests measured power savings up to about 43 percent at ten meters per second against hovering. Even after the weight penalty the design beat the fixed-wing original by about thirteen percent. Projections give the drone roughly 47 minutes of endurance and a 28-kilometer range.
