China can now test launching weapons from aircraft traveling at hypersonic speeds in a powerful wind tunnel, helped by robotic arms.

Researchers at China's Aerodynamics Research and Development Center in Sichuan province have developed a new captive trajectory system (CTS) that holds an aircraft in place using robotic arms, according to the South China Morning Post, enabling them to test how the craft pitches and rolls in all possible directions at extremely high speeds, as well as how the high speeds affect the release of objects like missiles.
