The theme of this year’s National Science Popularization Day is “Start again after a century and move towards high-level science and technology to be self-reliant and self-reliant”, and the sub-theme of Fujian Province is “Promoting high-quality development and promoting high-quality life”. In order to welcome the 2021 National Science Popularization Day, various places in the province will carry out a variety of science popularization activities from September 15th to 21st.

html On the morning of the 112th, a wonderful aerospace science popularization activity was launched at the Minhou Zhuqi Heliport. Fuzhou Gulou District Science and Technology Association and Gulou District Related Work Committee jointly organized Pingtung Community of Huada Street in Fuzhou City and Fujian Province Love Volunteers to Help the Elderly The savings center organized 15 groups of young families to participate in this science popularization activity.

Get on the helicopter and experience the "static pilot"

As soon as you arrive at the destination, the instructor will take you into the helicopter warehouse. There are three helicopters parked in the nearly 3,000 square meter warehouse. The children who saw the helicopter for the first time were amazed. The commentator introduced the structure, purpose, cost, etc. of the helicopter to everyone. He also focused on the differences in the structure of the two helicopters and how they completed search, rescue and other tasks. Then, the long-awaited part for the children came. They boarded the Schwarzer 300C helicopter one by one and experienced a "static pilot". The Schwarzer 300C helicopter is mainly used for flight training. The children were so excited to get on the helicopter that they looked here and touched it. Under the introduction of the instructor, they learned more about the structure of the helicopter.

Not only are children very curious about helicopters, but many parents can't restrain their desire for knowledge. One parent "badged" the commentator and asked: "Helicopters don't need to glide, why do they have wheels?" "This is mainly a helicopter. It is needed when transferring from the warehouse to the apron..."

Later, Teacher Gao Xiannong from the Provincial Aeronautical Society gave everyone a wonderful high-altitude performance. The drone sprayed colorful smoke, set off fireworks, and performed somersaults in the air... Each of the difficult moves drew gasps of exclamation from the audience.

Homemade simple rocket, flying 50 meters high

After the performance, everyone moved indoors, and Teacher Gao gave the children the "First Lesson in Aeronautics and Astronautics". "Human beings have worshiped high altitudes since very early on, and people all over the world are exploring its mysteries." Teacher Gao spoke passionately about the history of China's aerospace development, starting from the story of Wan Hu, an official of the Ming Dynasty who was the first person in history to try to launch a rocket. The story begins with Qian Xuesen returning to the embrace of the motherland without hesitation in the early days of exploration, to the successful launch of my country's first artificial satellite "Dongfanghong-1" and the first manned spacecraft "Shenzhou 5", to today's deep space exploration, Everyone was deeply attracted by the wonderful lecture content.

After a wonderful lecture, Teacher Gao led everyone to make a simple rocket. The children and parents followed the steps to complete the fixation of the base, barrel and parachute, and then installed the model rocket engine. Finally, the children came to the helipad with their results and began to complete their launch mission. "5, 4, 3, 2, 1, launch!" After pressing the launch button, the homemade simple rocket flew up to an altitude of 50 meters with a "swish" sound, and then slowly landed with the opened parachute.

Teacher Gao Xiannong has been engaged in aerospace research for more than 50 years. He is regarded as the "teacher" of aviation science popularization in Fujian Province by many primary and secondary school science and technology teachers. After retirement, he is still actively studying, setting up a professional drone studio, and strives to be the first in science popularization work. Wire. Teacher Gao told reporters that he hopes to inspire children's love for aviation and technology through this practical activity.
