Recently, high-definition photos of the sixth-generation fighter jet of Chengfei showed a new upgraded serrated tail design at the tail position, with a unique shape behind it. The flying wing configuration itself has eliminated the traditional vertical stabilizer, while the serrated edge tail can serve as an auxiliary control surface without increasing the radar cross-section, balancing stability during low-speed flight and maneuverability during high-speed penetration. More importantly, the serrated structure allows the airflow passing through the tail to spread more evenly backward, reducing vortex formation, thereby lowering flight noise and drag, and improving fuel efficiency.
In terms of stealth performance, when radar waves hit the serrated surface, they are directed to scatter in specific directions rather than reflecting back to the radar receiver, which can significantly reduce the radar cross-section of the aircraft.
