Li Yifan

On July 9, 2022, Hunan News Broadcast reported that Li Yifan, a outstanding young man who was successfully selected in the "Xiaode" talent support plan in Hunan Province in May this year. When he was in contact with the model of aero and undergraduate, he served as the president of the China Agricultural Aviation Model Association (now UAV Association) and led the team to win the award repeatedly. Kg -level transport drones, Li Yifan's drone journey drawn a gorgeous trajectory.

Breakthrough: departed from "1"

The pulley slowly rolled forward, and the runway of the airport changed slowly from slowly, and the propeller rotated quickly, driving the fuselage gliding forward, taking off steadily. In the early morning of July 15, 2021, the SA70U fixed wing drone developed by the Li Yifan team was successfully flew at Zhanghe Airport in Hubei.

The maximum take -off weight of this drone is 700kg, and the take -off and landing distance is only 150 meters. Its short -range take -off and landing capacity has reached the leading domestic level. At the same time, the functions of the front wheels of the electronic control, the parachute of the whole machine, and the expansion of the fuel tank. Compared with similar models, it has a significant advantage in the short -range and landing capacity, environmental adaptability and cost of use. Communication, environmental monitoring, logistics and other fields.

Li Yifan is debugging the drone

After graduating from Master Hua Nong in 2019, Li Yifan joined Hunan Shanhe Technology Co., Ltd. and served as a flight control engineer. The first difficulty of his work was to change a 700 -kg fixed -wing -manned manned machine to a drone.

As a manned aircraft, the original aircraft is very good, and it is easy to adjust the adaptation according to the environment to change its flight status. However, when it is changed to drones, excellent mobility will affect the stability of take -off and running, making it operating hidden dangers and becoming great disadvantages.

Although the reference materials are extremely limited and the experimental simulation process is difficult, it is just like the calm mentality when I have witnessed myself when I stayed up late and worked hard. Continue to adjust the research direction and continue to optimize.

On July 15, 2021, after two years of hard work, the drone was perfectly lifted with the expectations of everyone, and it landed steadily after completing the established task. All the payments were rewarded. At that moment, Li Yifan and the team members cheered loudly.

For Li Yifan, no matter how many times, the moment of the drone can make him feel the same joy and blood over and over again. The flying dream that has been buried in my heart since the age of eighteen, now turns into reality.

Growth: Tour "0" from "1"

Departure: Aviation model "enthusiast"

In September 2013, Li Yifan became a freshman at a South China Agricultural University. At that time, he couldn't think of it, he was about to embark on the life path he had never thought about on this Bauhinia campus.

Li Yifan has been interested in the model model since he was a child, but because of his busy school, this interest was put on hold. One day of the freshman year, Li Yifan was pleasantly surprised to find that there were group students in the playground who were manipulating the drone. Watching the drone flying freely under the sky, he moved his heart and joined them. Since then, he has become a "model enthusiast" with this group of friends who love the blue sky and like -minded.

Li Yifan recalled that at that time, the models of the airlines were basically processed by KT, light wooden boards, and carbon fiber sticks. Due to the lack of laser cutting conditions, many times they can only use a beautiful worker to grind the wood little by little, and one grind is the whole night. For a long time, Li Yifan produced and repaired the aircraft in the accompaniment of the dissolved night. The next day, while taking advantage of the morning light and the sports field, there were fewer people to test flight.

However, due to the "entered the pit", his technology is still insufficient, and the throttle is not timely, the position of the throttle is shifted, the time perception error is caused ... often the "explosor" (refers to improper operation or machine failure and other factors due to various errors. As a result, the flight models fall abnormal). The plane fell to the ground again and again, but Li Yifan's mentality was flat, "Go stay up late to do it again."

The reciprocating test flight and adjustment did not eliminate Li Yifan's will, but instead made him more firm. He became a member of the South China Agricultural University Set Model Association and devoted himself to the model of the model with full enthusiasm.

In 2015, with his outstanding performance in the team, Li Yifan became the third chairman of the Hua Agricultural Aviation Model Association (now the Huaonong UAV Association). This year, five members of the Hangs Model Association formed a competition team, representing Hua Nong's two national awards in the China International Aircraft Design Challenge (CADC). Excellent achievements make the Hangs Model Association stand out among many student organizations in the school, attracting more and more students who love drones to join, and the Hang Model Association also officially renamed the "UAV Association" in the subsequent development process. Li Yifan, who grew up with the association, also gained a lot: During the college period, he won the second prize of the National Discipline Contest 1, 3 third prizes, and 6 in invention patents, and undertake 1 national innovation and entrepreneurial project.

Today, the Hua Nong Drone Association has become a large -scale student society in the school, representing Hua Nong countless awards in various large -scale events. Along the way, Li Yifan and his teammates went from the "enthusiasts" who met with interest to the teammates who fought side by side and became a friend in life. Looking back at the youthful years in Hua Nong, Li Yifan lamented: "No matter what, from '0' to '1' is a very worthy process."

Turn: Entering the world of drones

Talking about the experience of Li Yifan's association in Hua Nong and the drone, Li Jiyu, a professor and instructor of the School of Engineering, the founder and instructor of the South China Agricultural University drone association, is a name that cannot be bypassed. Speaking of Li Jiyu, Li Yifan seemed to have endless words: "Teacher Li supports our ideas, and also gives us a lot of freedom, and will not interfere with our design plan too much. Very supportive!"

In the last semester of the sophomore year (2014), in order to learn more about the production of the aircraft, Li Yifan selected Li Jiyu's "Basic Foundation" of Li Jiyu, and a story of "Bole and Liangju" opened.

"Generally speaking, those who like me or get high scores in my class are all students in the School of Engineering. What I did not expect is that Li Yifan is a non -engineering student, and he is very familiar with the aircraft. , And have a certain professional basic knowledge, the last effect is also very good. "Li Yifan's talent and enthusiasm stunning Li Jiyu. In the course exam, he gave a full score to the students of the non -college.

This full score inspired Li Yifan. With the encouragement of Li Jiyu, Li Yifan successfully transferred to the automation major of the School of Engineering in his sophomore year and officially embarked on the road of drone research. In 2017, Li Yifan continued to stay in the School of Engineering after graduating from undergraduate graduate, and began a deeper exploration and research.

Li Yifan who goes to the field

I heard that Li Yifan successfully developed a 700 -kg fixed -wing drone flight control system, Li Jiyu was both pleased and excited: "I am proud of him! I hope he can maintain his original intention in the aviation field and continue his talents. Become the pride of Hua Nong and contribute greater contributions to the country. "As the instructor of the Hua Nong Drone Association, Li Jiyu said that in the future, it will continue to combine the training of students' drone competitions with the scientific research direction of agricultural engineering to highlight the characteristics of Hua Nong's characteristics With advantages, cultivate more professional talents, and contribute to the school's "double first -class" construction and the development of the country's "agriculture and rural" cause.

From the "foreigners" of the drone to the small achievements today, there are many people Li Yifan who wants to thank: "Thanks to the platforms and opportunities provided by my alma mater and unit for me, thank the teachers and colleagues for helping me, and also for my guidance. Also Thank you for your firm choice and giving without regrets. "

The 20 -year -old Li Yifan firmly chose his love and struggled. The 27 -year -old Li Yifan answered all hesitant and hovering in his youth with excellent results.Looking back at the road, Li Yifan was emotional: "What you love may also be your future career. I hope that the younger brothers and sisters will cherish every minute and every second in school.Miss the pure youth time. "Struggle is the brightest background of youth

Li Yifan uses practical actions

The youth that makes Fenghua Zhengmao

Shine shining in the flying of the drone

Now

Li Yifan will also bring his love

Start again

Youth from sharpening

Life is sublimated by struggle

Looking forward to every Hua Nong student

It can be firm as Li Yifan's goal

And put into action

Fly dream in Hua Nong and realize yourself
