It is understood that during the Airshow, SAST will also reach a cooperation agreement with Pinghu Municipal People's Government on the aerospace Pinghu industrial base project. The total amount of all projects is 17.981 billion yuan.
There are many highlights in SAST’s exhibits this year, including "old acquaintances" which appeared last year: China's first solid-fuel bundled carrier rocket - Long March 6A, and China's first solar exploration satellite - "Xihe" and space refueling aircraft - "space refueling vehicle", etc. There are also "new faces" on the show: China's third generation low orbit meteorological satellite series Fengyun-5, Landsat-1, atmospheric environment monitoring satellite, medium and long range air defense missile system, etc. In addition, there are "model houses" of aerospace "intelligent manufacturing": Guangdong Hong Kong Macao satellite intelligent manufacturing center, digital intelligent manufacturing platform for aerospace complex component welding inspection, etc.
In the defense equipment exhibition area, a new type of air defense weapons and equipment came into public view for the first time. It is the medium and long-range air defense missile weapon system newly developed by SAST. On the basis of the third generation of medium range air defense weapons and equipment, this product has been improved and upgraded by using a large number of advanced technologies of the fourth generation of air defense weapons. It has "piercing eyes", "smart brains", and its own "anti-fraud center". It has excellent anti saturation, anti-jamming and automatic combat performance, and can efficiently intercept precision guided ammunition, ballistic missiles, combat aircraft, etc., which can not only protect its own fixed targets, but also cover mobile combat forces. In addition, SAST also exhibited the "Cooperative Operation Command and Control System", which packs and compresses the "headquarters" of the defense system. Through intelligent information fusion, auxiliary decision-making and other technologies, it can command and control the joint operations of multiple air defense weapons and equipment, and greatly improve the joint operational effectiveness of weapons and equipment.
In the launch vehicle exhibition area, Long March 6A, China's first solid-fuel bundled launch vehicle, which successfully completed its first flight mission in March this year, appeared again. It is reported that Long March 6A is a carrier rocket series with reasonable carrying capacity and high cost performance. It is based on the successful first flight of a new generation of rockets, and fully inherits the existing technology. It adopts modular, combined and serialized design, and combines different quantities of solid-fuel boosters and liquid-fuel core stages to form a carrier rocket series, and features "cross-border cooperation, unattended operation, intelligent diagnosis, and accurate landing". Its successful first flight achieved a series of technological breakthroughs such as solid/liquid fuel bundling, which promoted the new generation of carrier rocket to be more efficient, more intelligent and safer, and laid a solid foundation for the innovative development of the new generation of carrier rocket in China.
In the satellite exhibition area, the "Xihe" solar exploration satellite, the Landsat-1 satellite, the atmospheric environment monitoring satellite, and the Fengyun-3 and Fengyun-4 meteorological satellites made a stunning appearance with naked eye 3D effects. Among them, the "Xihe" solar exploration satellite adopts the internationally first "dynamic and static isolation, master-slave cooperation" magnetic levitation satellite platform, realizing the internationally first solar Hα-band spectral imaging exploration, which is of great significance for the subsequent solar space exploration missions and the promotion of collaborative innovation and development of space science, space technology and space applications in China; Landsat-1 Group 01 consists of A and B satellites, which have been successfully launched into orbit on January 26 and February 27, 2022 respectively, which formed the world's first L-band distributed SAR mapping double satellite constellation, which can provide localized observation data for geological, seismic, land, disaster reduction, mapping, forestry and other application fields; The atmospheric environment monitoring satellite is the world's first laser carbon dioxide exploration satellite - the atmospheric environment monitoring satellite. It was successfully launched into orbit on April 16, 2022, achieving high-precision, large-scale, all-weather, and multi factor comprehensive observation. Many of its indicators leads internationally. It significantly improves China's international influence in the field of atmospheric remote sensing and laser remote sensing, and helps China in "reaching the peak of CO2 emissions" and "carbon neutral", ecological civilization construction and other national strategies. The Fengyun-5 satellite displayed in the form of model is the third generation of low orbit meteorological satellite system currently under research in China. It will use the new generation of intelligent large platform for low orbit remote sensing from SAST to achieve global, all-weather, all-time and high-precision meteorological and climate monitoring, with space, time and sphere integration, and form comprehensive observation capability of low orbit meteorological satellite with "complete orbit, complete elements and advanced technology".
The Guangdong Hong Kong Macao Satellite Intelligent Manufacturing Center, which was displayed in the form of a dynamic sand table, attracted the attention of many visitors. This is a typical demonstration of the commercial satellite batch production line of SAST, featuring efficient collaboration, ubiquitous awareness, automatic loading and testing, fine quality control, intelligent control, etc., which can meet the requirements of multi variety, variable batch and flexible production of small satellites, and greatly improve the batch production capacity, assembly efficiency and intelligent control level of production process of small satellites. It is understood that the Guangdong Hong Kong Macao satellite intelligent manufacturing center project is an important part of Hong Kong's "re-industrialization" strategy.
Before the digital intelligent manufacturing platform for welding inspection of aerospace complex components, there are also many visitors wandering around. Some are carefully observing the friction stir welding model; Some wear AR glasses and control the inspection robot to inspect the weld seam through gesture operation, so as to experience the charm of the industrial meta universe; Others have experienced the addiction of "Iron Man" at the exhibition site by interacting with the staff through AR glasses and decomposing the digital twins of the detection system. The project is based on the transformation from aerospace manufacturing to aerospace intelligent manufacturing. It gathers the latest artificial intelligence technologies such as industrial internet, big data, AI recognition, cloud computing, digital twins, and meta universe, and demonstrates collectively the firm belief and latest achievements of SAST in implementing "manufacturing power, quality power, aerospace power, and digital China", so that the audience can understand the new height that aerospace digitalization and informatization development has reached through rocket welding and testing process while experiencing it immersively.
In addition, the refueling service aircraft known as the "space refueling vehicle" and the low-cost universal interface commercial satellite derailment device - "derailing sail" were also welcomed by the audience. The refueling service aircraft is used to provide refueling service for satellites that run out of fuel at the end of their service life. It is a "space refueling vehicle" that extends the service life of satellites. "Derailing sail" is a space deployable membrane structure, which is compact in its retracted state. It enters the orbit with the satellite and unfolds after the end of the satellite's life. It uses the low orbit thin atmospheric resistance to significantly accelerate the satellite orbit attenuation, which is expected to contribute to alleviating the severe situation of space debris.
At this Airshow, SAST also exhibited a variety of stand-alone products such as independently developed commercial satellites, represented by VDES satellite, South Guangdong Science satellite, Minhang Youth satellite, and ion propulsion systems for commercial aerospace, highly reliable subminiature star sensors, separation measurement sensors, optical navigation sensors, gallium arsenide solar cells, as well as the "dome shield" low altitude small aircraft intrusion prevention system, laser processing intelligent production unit, air cooled fuel cell system for UAV, portable fast detection mass spectrometer, underground fully mechanized mining and tunneling inertial navigation system, marine anti rolling gyroscope and other key products and technologies in aerospace technology application industry.
Since 1996, SAST has been growing with the Airshow. Over the past 26 years, from the initial development and exhibition of a single model to the blooming of multiple products and technologies in many fields, the number of exhibits from SAST has grown geometrically, and the number of domestic and foreign visitors and aerospace fans attracted by the booth has increased dramatically. This not only demonstrates the growth of SAST itself, but also the growing richness, interactivity and international influence of the Airshow, which provides a valuable display window for defense science, technology and industry enterprises like SAST.
