From "meteorological special police" to "portable air conditioning" space technology comes to you

People's Daily Online, Beijing, May 18 (Zhao Zhuqing) Aerospace technology civilization is not new. The diapers used by the baby, the vegetable bags in the instant noodles, etc., these products were originally transformed from aerospace technology, and nowadays, in China, the space technology has been transformed into civilian use, and it has covered many automobiles, electronic communications, medical instruments, etc. a civilian field. Recently, the reporter saw a large number of civilian products from the aerospace technology innovation in the Second Academy of China Aerospace Science and Technology. These products have expanded the new technology with independent intellectual property rights in the aerospace field to the mass market, and once again created a number of “ the first".

"Weather Special Police" monitors dangerous weather

Low-altitude wind shear, known as the "airport killer", is a kind of disturbance to the aircraft running severe weather, seriously threatening passenger safety. The 23 aerospace science and technology institutes based on various aerospace traditions of radar technology, developed a "meteorological special police" - civil aviation wind shear warning system, overcoming the practical problems of lack of detection means, early warning, low precision, not only can The takeoff and landing of the aircraft provides real-time wind shear warning information, and can also provide airport weather forecasters with weather forecasts for the airport for the next 48 hours.

Since March 2016, the system has been commissioned at Tianjin Binhai International Airport and has been recognized by experts and users. Next, it will be promoted in a wider range of airports in China.

Microwave "bake" high-grade fabric

"China is a big textile country, but it is not a textile power. This is mainly because of the lack of high-grade fabric technology. Nowadays, aerospace technology has emerged as the necessary drying equipment for the textile industry, making the production of high-grade fabrics possible." China Aerospace Li Tongjin, general manager of Beijing Changfeng Broadcast Communication Equipment Co., Ltd., a subsidiary of the Second Institute of Science and Technology, said that the company used the microwave drying equipment produced by aerospace technology to dry the fabric with "microwave", breaking through the countries of Italy, Britain and other countries. Monopoly, low-temperature drying, excellent drying effect on high-density cheese yarn, and effective fiber quality and softness.

It is understood that this drying equipment can also provide fast and pollution-free drying services for wood, dried fruits and food.

Fire with a "missile"

High-rise building fires have always been the "difficult" of the fire industry. Not only the general fire trucks are "not enough", but also the problems of cars and people "can't get in" and rescue work "can't be opened". Especially in the bustling commercial streets and communities, this problem is more prominent. The most advanced fire trucks now take twenty minutes to start work.

Developed by China Aerospace Science and Technology Second Institute 206, the bomb-type high-rise building dry powder fire truck evolved from aerospace technology, it takes only 3 minutes to reach the fire scene and launch fire extinguishing bombs, which greatly solves the city's high-rise fire. the problem we are facing.

In addition, the urban population density is large, and how to prevent secondary damage during the fire fighting process is also very important. According to reports, the bomb-type high-rise building dry powder fire truck uses space launch technology, control technology and information processing technology, using "green" launch technology, can deliver fire-fighting bombs with great precision, and spread high-efficiency and safe fire-extinguishing agent on the fire site. It will not be "biased" and will not cause harm to personnel.

"Private air conditioner" under the scorching sun

In the high temperature environment, the sun and the humid air of the hot sun have seriously affected the operational efficiency and quality of life of special police, traffic police, steel stove workers, welding workers in confined spaces, and outdoor sports personnel.

The response of the special environment is precisely what aerospace technology is good at. The Aerospace Science and Technology Second Institute 206 used space technology to develop a "single air conditioning system". When a person wears a liquid cold suit, the coolant absorbs the body heat and then flows to the low temperature heat exchanger for cooling. After cooling, it enters the liquid cooling suit. In this cycle, the micro-refrigeration system discharges heat to the outside environment.

After continuous improvement and optimization, the second generation of individual air conditioners can be “converted” to meet the different needs of special personnel in different environments, and has the characteristics of small size, light weight, easy to carry and easy to use.

According to reports, from 2014 to 2016, through the trial and feedback of fire officers and soldiers, public security officers and front-line personnel of high-temperature operation, the structure and function of individual air-conditioning have been continuously improved, and it is expected that official products will soon be put on the market.
