Beihang Student's Unmanned Aerial Vehicle Feng Ru-3 has a world record duration of 30 hours

On October 3, after 30 hours, 6 minutes and 42 seconds of uninterrupted flight, Beijing University of Aeronautics and Astronautics drone "Feng Ru 3" set a world record for the life of 25 kg to 100 kg oil-powered drones. The drone is developed, produced and manufactured by more than 30 freshmen and sophomore undergraduates from Beijing University of Aeronautics and Astronautics Beijing University and Feng Ru Shu. Observers WONG, TAK KAY KEITH from FIA confirmed the flight time and the effectiveness of the flight, which will be officially approved by the International Air Transport Association (FAI).

The "Feng Ru No.3" drone adopts the conventional layout. The length of the wingspan is about 10 meters. The whole machine is black. The tail is printed with a bright five-star red flag and the emblem of Beihang. The fuselage is short and streamlined, like a submarine. Made of high-strength composite material, the rear propeller, the total weight of the aircraft after filling the fuel is 75.44 kg.

To tribute to the motherland and pay tribute to the older generation, the "Feng Ru 3" drone team hopes to sacrifice the 70th anniversary of the founding of the People's Republic of China by creating a world record in flight, paying tribute to the 110th anniversary of the first flight of China Airlines and Feng Ru. The goal is to create a world record for the fixed-wing oil-powered drones of 25 kg to 100 kg. This not only requires that the lift-to-drag ratio is sufficiently high, but also requires a substantial reduction in the weight of the structure and an increase in the specific gravity of the fuel, thereby ensuring the reliability of long-time flight, which is technically difficult.

The record flight 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 aeronautical school and was not allowed to refuel during the flight. In the given amount of oil, "Feng Rusan" set a new world record for new life time in drones of the same weight class and power type. . Potential commercial and military applications for the project include mapping and communications.

In October 2018, the first phase of the Beijing-based Feng Ru Shu College was established, recruiting 33 undergraduate students in the first and second grades from Feng Ru Shu Yuan and Beijing College. The average age was less than 20 years old and began the “Feng Ru 3”. Production. Under the guidance and careful guidance of the instructors, the production team adopted advanced super-large aspect ratio wing, integrated composite molding, autonomous take-off and landing flight control and navigation technology, and repeated calculations, tests, tests and test flights. In order to meet the requirements of aircraft performance, from the overall design to the study of the details need technical innovation, repeated practice and hard work. After a period of time, the students gradually adapted to the environment of the factory, and the project also ushered in one new development. On August 4th, the white "Feng Ru 3" aircraft took off and the flight test was successful. Since then, after a series of adjustments, the overall weight loss of the aircraft has exceeded 15 kg, and the endurance has been greatly enhanced.

In the end, at 8:06:24 on October 2, 2019, Beijing time, the "Feng Ru No. 3" with beautiful posture and superior performance took off from the Anyang Aviation Sports School of the State Sports General Administration. After 30 hours, 6 minutes and 42 seconds, it was fully autonomous. The pattern landed smoothly, and a group of young people with an average age of less than 20 years old wrote a new world record.
