🇨🇳 A Chinese engineer has demonstrated a jet-powered personal flight system developed by a research team affiliated with Zhejiang University, lifting off and flying above the ground during a university open-day demonstration. The pilot, identified as Jiao Bojing, is a mechanical systems and test-flight engineer with the JetRob team at Zhejiang University’s Huzhou Institute. Video from the demonstration shows Jiao taking off vertically, hovering, maneuvering through the air and landing using the backpack-mounted propulsion system. According to Chinese reporting, the jetpack uses five jet engines: two controlled by each arm and another mounted behind the pilot. The system is reported to be capable of speeds of up to approximately 100 kilometers per hour, or about 62 mph. The technology is part of ongoing research into personal jet-powered flight systems, an area being developed by a small number of companies and research teams around the world. #AfriVisionMedia #China #ZhejiangUniversity #Jetpack #Aviation
