Core Viewpoint - The "Yunfan" unmanned vessel developed by Shanghai Jiao Tong University successfully conducted close-range meteorological observations of Typhoon "Butterfly" near Hainan Island, demonstrating its capabilities in extreme marine weather monitoring [3][4]. Group 1: Technology and Innovation - The "Yunfan" unmanned vessel is a result of ten years of technological breakthroughs in wave energy utilization, wind-wave hybrid drive, and multi-source energy management by a research team led by Professors Tian Xinliang and Wang Peng [4]. - The vessel features a surface buoy, underwater traction device, and a sail propulsion system, allowing it to convert wave motion into forward thrust while utilizing solar panels for energy [4][5]. Group 2: Operational Performance - During its mission, the "Yunfan" maintained a control radius of less than 100 meters and successfully tracked the typhoon's path, with a tracking error of less than 50 meters [3]. - The vessel recorded significant meteorological data, including maximum wave heights exceeding 6 meters and wind speeds over 30 knots, effectively capturing the atmospheric changes in the typhoon's core area [3]. Group 3: Future Applications - The "Yunfan" unmanned vessel is capable of autonomous operation at sea for several months without external energy, making it suitable for various applications such as oceanographic monitoring, ecological surveys, and resource development [5]. - It is expected to contribute significantly to China's digital and smart ocean initiatives, enhancing marine observation and early warning capabilities [5].
