According to the Guinness World Records official account, three 16-year-old Tianjin teenagers Yao Siqi, Guo Jiyuan, and Zhang Wei recentlyWith a speed of 358.36 kilometers per hour, it set a new Guinness World Record for the "fastest ground speed of a remotely controlled micro quadcopter".This speed exceeds the operating speed of most high-speed trains, and the aircraft weighs less than 250 grams.
According to reports, this record refresh is not a simple improvement, but a systematic reconstruction around the "extreme speed" goal.
Before the challenge, the team thoroughly studied the design plan of the previous record holder Xu Yang Kaiyuan. Its rack design, calculation methods and engineering experience provided them with a clear starting point.
On this basis, the team locked the core breakthrough points at:The entire machine was redesigned within the 250-gram weight limit to ensure that every design directly serves the speed goal.
During the development process, the team experienced many failures. The first prototype was damaged during its first flight, and another aircraft unexpectedly disintegrated when approaching 300 kilometers per hour.
technical level,The team used T700 carbon fiber frame and titanium alloy SLS 3D printed motor bracket.And under strict weight restrictions, the ultimate speed is continuously increased by reasonably releasing power and reducing wind resistance.
It is understood that the team has shared this design as open source on GitHub for the reference of more enthusiasts and researchers.
