China’s stealth design software PADJ-X finds potential flaws in B-21 bomber configuration

A powerful aerospace simulation tool developed by Chinese researchers may have exposed potential vulnerabilities in the design of the United States’ most advanced stealth bomber, the B-21 Raider. The “all-in-one” PADJ-X software system, based on adjoint optimisation technology, was unveiled last month in a paper published by the peer-reviewed Acta Aeronautica et Astronautica Sinica. The system, which may be the first fully integrated, multidisciplinary platform for stealth aircraft design, uses...
