Latest Patents
One of Zhang Liu's latest patents is titled "Optimizing trajectory of unmanned aerial vehicles." This patent outlines methods, non-transitory computer-readable media, and systems for trajectory optimization in high-altitude, long-endurance aircraft. The systems described can generate an optimized flight plan during active flight by utilizing a greedy algorithm with buffering. The invention identifies multiple possible states and selects the top states based on energy changes associated with transitioning to each state. This process continues through incremental time periods until a final state is selected, allowing for efficient flight planning.
Another notable patent is "Banked yet straight flight." This invention describes an aircraft design that includes first wings configured to produce lift in one direction while moving in a perpendicular direction. These wings can also generate centripetal force when the aircraft banks. Additionally, the design incorporates second wings that produce a counter force to reduce the centripetal force during banking, enhancing the aircraft's stability and maneuverability.
