Aerospace Science and Industry Aerospace Plane
The China Aerospace Science and Industry Corporation had made many achievements in the space shuttle field.
The Shenlong aerospace plane developed by the company had completed 276 days of in-orbit flight and successfully returned to the designated landing site in May last year. In May this year, it was monitored to have an orbital ascent of 0.1 kilometers.
In addition, the Cloud Soaring Sky Plane was scheduled to be tested by 2025. In September 2018, Tengyun Engineering realized the first flight verification of the combined engine mode conversion in China. According to the plan, the first flight test would be conducted in 2025 and it could be put into use around 2028. The aerospace plane was a multi-functional aircraft that could fly in the dense atmosphere, near space, and orbital space. It could be used as a re-usable space transportation system and was of great significance in both military and civilian fields. For example, in the civilian aspect, it could meet the needs of space tourism, transporting astronauts, satellite launch, space station cargo replenishment, and space emergency rescue; in the military aspect, it could be used for reconnaissance, long-range strikes, and bombing, and competing for air supremacy and space supremacy.

aerospace model
There were many types of aerospace models. In terms of venues, there was the first model museum in China, the Beijing Aerospace Model Museum, which included buildings such as the "small airport", which was mainly a sea, land and air model activity area, surrounded by green areas.
In terms of competitions, the 2024 National Aerospace Model (Aerospace and Free Flight) Championship was held in Chenbaerhu Banner, Hulunbeir City. Many teams and athletes from many places participated in the competition, setting up three major competitions: free flight, aerospace and remote control glider. The 2023 National Aerospace Model (indoor project) Championship was held in Luwan Sports Center, Huangpu District, Shanghai City.
In terms of model production, there were military models led by workers from Shandong Province, including the space station model. The model was realistic, could be disassembled and assembled, and had complete functional configuration. It was purchased by the National Defense Education Base. There were also aerospace models that relied on 3D printing technology. For example,"Casaim Smart Manufacturing" used 3D printing technology to make aerospace shuttle rocket models. It had many advantages, such as breaking through the limitations of traditional design thinking and reducing the risk of parts assembly errors. It also had a variety of printing technologies and equipment as well as commonly used printing materials.
From the definition and classification of the aerospace model itself, the aerospace model was an aerospace model that was propelled by a model rocket engine. It was equipped with a recovery device and composed of non-metallic components. It was divided into 10 main categories, such as the S1 altitude model rocket and the S2 load model rocket.(Except for the S7 category, each category was classified according to the total impulse of the engine.) In addition, 1:1 restored aerospace models such as military aerospace equipment could be seen at the Mianyang Science and Technology Fair Aerospace Exhibition.

aerospace invention
The following are some of the inventions related to aerospace:
1. Tethered satellites: Inspired by kites, aerospace scientists invented tethered satellites. They were connected to space shuttles, spaceships, or space stations by ropes or chains. They could be launched or recovered at any time to capture electrical energy in space, which was difficult for ordinary satellites to accomplish.
2. [The word 'aerospace' was invented by Qian Xuesen.] Although his report to the central government from the United States was about the aerospace industry, the actual content was about missiles, rockets, satellites, and other aerospace matters. Inspired by Chairman Mao's poem,"Looking at a thousand rivers from afar," Qian Xuesen used the word "sky" to represent the universe and invented the word "aerospace."
3. ** Civil invention derived from aerospace technology **
- ** Freeze-dehydrated vegetable technology **: Originated from the Apollo program of the United States, it was developed to solve the problem of astronauts eating vegetables to supplement vitamins. Later, it was widely used to make dried vegetables and dried fruits.
- ** High-efficiency diapers **: invented by Chinese engineer Tang Xinyuan of NASA in the 1980s. It was originally used to solve the problem of astronauts going to the toilet in space. Later, it was transferred to civilian use to reduce the production cost of diapers.
- ** High-efficiency water purification system **: developed by NASA, including iodine-based disinfection and silver-copper alloy disinfection technology. It is now widely used in urban tap water purification.
- Memory cotton (space memory pillow material): Used on the space shuttle to relieve the pressure of astronauts and protect the spine. It was developed as a civilian (medical) product in the early 1990s.
4. Since 2010, China has actively expanded the civilian use of aerospace technology. More than 2000 aerospace technologies have been converted to civilian use. For example, the market share of friction stir welding equipment has exceeded 50% and the production line has been imported overseas. The carbon fiber composite technology has led the development of lightweight vehicles to help the development of new energy vehicles.
