China Suspends Export of Rare Metals Amid Escalating Trade Tensions with US

Chinese scientists at the Taihang National Laboratory have successfully completed ground tests on a new turbojet engine capable of reaching speeds up to Mach 4, as reported by the South China Morning Post. This innovative engine employs artificial intelligence and a dual-mode design reminiscent of the J58 engine used in the retired Lockheed Martin SR-71 'Blackbird'.
The development of this turbojet represents a significant step in China’s ambitions to create fast reconnaissance aircraft, similar to the legendary American model known for flying at altitudes above 85,000 feet and exceeding speeds of Mach 3.2. The project reportedly faced challenges, particularly regarding discrepancies between simulated and actual engine performance, but technological advancements in manufacturing precision have aided its success.
The research team highlighted the incorporation of an AI algorithm designed to enhance real-time monitoring of engine performance, a crucial factor for the viability of military applications. With ongoing improvements in engine technology, this development may enable China to achieve a competitive edge in aviation technology, potentially closing the gap left by the absence of a viable supersonic reconnaissance platform since the 'Blackbird's' retirement in 1999.
