China conducts test flight of a giant coil array. Can it detect nuclear submarines?
China has successfully conducted a test flight of a large airborne electromagnetic detection system designed to locate submarines. The system utilizes a giant coil array towed by a helicopter, which generates a magnetic field to induce eddy currents in conductive materials like submarines. By analyzing the secondary magnetic field generated by these currents, scientists can identify the presence, type, and depth of submerged objects. This engineering feat, detailed in a paper published in Acta Aeronautica et Astronautica Sinica, was led by researchers from Beihang University and the Chinese Academy of Sciences. AI
