On October 8, after an uninterrupted flight of 30 hours, 6 minutes, and 42 seconds, the Beijing University of Aeronautics and Astronautics drone "Feng Ru III" set a world record for the longest battery life of 25 to 100 kg oil-powered drones. Observers of the International Aviation Federation (FAI) confirmed on-site that the flight time and flight activities were valid, and the record will be officially approved by the International Aviation Federation.
It is understood that the "Feng Ru III" unmanned aerial vehicle was developed, produced, and manufactured by more than 30 freshman and sophomore undergraduates from Beijing University of Aeronautics and Astronautics and Feng Ru College. The unmanned aerial vehicle has a wingspan of about 10 meters in length, the whole aircraft is black, the tail is printed with a bright five-star red flag and the Beihang school badge, the fuselage is short, streamlined, like a submarine, the whole aircraft is made of high-strength composite material, the rear With the propeller installed, the total weight of the aircraft after being filled with fuel is 75.44 kg.
To create a world record of 25 kg to 100 kg of fixed-wing oil-powered drones, not only is the lift-to-drag ratio high enough, but it also requires a significant reduction in the weight of the structure and the increase in the proportion of fuel to ensure the reliability of long-term flight. The technique is very difficult.
The record-breaking flight event was held at the Anyang Aviation Sports School of the State Sports General Administration. The aircraft hovered at a height of 300 meters above the aviation school. No refueling was allowed during the flight. On a given amount of fuel, "Feng Ru No. 3" set a new world record in the life of the UAV of the same weight class and power type. .
In October last year, Beihang Fengru Academy's first phase of science and technology innovation camp was established, recruiting 33 undergraduate first and second grade students from Fengru Academy and Beijing College, with an average age of less than 20 years old. Make. Under the organization and careful guidance of the instructor, the production team adopted advanced technologies such as large aspect ratio wings, integrated molding of composite materials, autonomous take-off and landing flight control and navigation, and repeated calculations, tests, tests, and test flights.
At 8: 6: 24 in Beijing time on October 2 this year, the "Feng Ru No. 3" with a beautiful posture and superior performance took off autonomously from the Anyang Aviation Sports School of the State Sports General Administration. After 30 hours, 6 minutes and 42 seconds, it landed in a fully autonomous mode. . As a result, a group of young people with an average age of less than 20 years has written a new world record.
