Foreign media: In 2015, a U.S. Navy F/A-18 pilot encountered an unidentified flying object (UFO) that resembled a spindle, hovering above the clouds with no obvious propulsion system, in the skies over the East Coast. The video "Gimbal" from this incident, which was declassified in 2021, sparked global speculation about unknown aerial phenomena.
Now, Chinese scientists have successfully tested a vertical takeoff and landing (VTOL) drone with an appearance similar to a "UFO". Its design is extremely similar to the mysterious object, featuring no traditional wings or tail fins, and it has demonstrated potential advantages such as long endurance, strong stability, and multi-mission adaptability during the experimental phase.
This new type of drone is still in the experimental stage. Its unique elliptical ring-shaped wing and four rotors that serve both lift and structural reinforcement functions represent a major change in aerodynamic design, and are expected to enhance the drone's endurance, stability, and multi-mission capabilities.
