Foreign media: The powerful aerospace simulation tool PADJ-X developed by Chinese researchers may have revealed potential weaknesses in the design of the United States' most advanced stealth bomber, the B-21 Raider. PADJ-X is a "versatile" software system based on accompanying optimization technology and may be the first fully integrated, multidisciplinary stealth aircraft design platform. The system uses algorithmic methods to calculate the optimal direction for all parameters simultaneously, greatly reducing computational costs.
By using PADJ-X to analyze the configuration of the B-21, the research team found that this bomber, which is undergoing intensive testing flights by the U.S. Air Force, may have shortcomings in aerodynamic performance and stability.
The researchers did not disclose the data used for analysis, but stated that through simulation, the aerodynamic optimization of the B-21 layout increased the lift-to-drag ratio of the aircraft by 15% and significantly reduced shock waves.
