From the floating of the large cruise ship "Huacheng" dock to the airworthiness certification of the large aircraft "Kunlong"; From the appearance of the new generation cargo spaceship "Light Boat" to the delivery of the upgraded large-scale breeding factory ship "Guoxin 1"... Recently, domestic large-scale sea and air equipment has continued to "update", becoming a strong witness of China's scientific and technological strength and comprehensive national strength. On April 28th, the second domestically produced large cruise ship "Aida Huacheng" successfully achieved a milestone of floating from the dock at Shanghai Waigaoqiao Shipbuilding Co., Ltd., a subsidiary of China Shipbuilding Industry Corporation. Also starting the "wave breaking" journey is the world's first 150000 ton smart fishery large-scale breeding factory ship, "Guoxin No. 1 2-1", which was recently delivered and put into operation in China Shipbuilding Group Beihai Shipyard. At the same time, domestic aerospace equipment is "riding the wind": the new generation of space "courier" light cargo spacecraft was officially unveiled on "China Aerospace Day"; The domestically produced large amphibious aircraft AG600 "Kunlong" has also recently obtained a market "access certificate". Compared to previous generation products, these sea and air equipment have more "hardcore" technological strength. Compared with the first ship, the construction efficiency and buoyancy integrity of the "Aida Huacheng" have greatly improved, marking an important breakthrough in China's shipbuilding industry's comprehensive construction of lean and efficient large-scale cruise ship design and construction capabilities. The 'Qingzhou' is a small and agile spacecraft with 'great wisdom' - this' low-cost, high reliability, high adaptability, and high intelligence 'features an integrated single cabin configuration design, flexible configuration of large capacity cold chain transportation, intelligent cargo management system, and diversified transportation capabilities. Compared with the first generation "Guoxin 1", the new generation of ship type aquaculture water has increased by 20%, and energy consumption has been reduced by at least 20%. More than 160 technological breakthroughs and optimization innovations have been achieved in functional layout, aquaculture system, new energy utilization, information integration and other fields. As the world's largest civilian amphibious aircraft in terms of takeoff weight, the AG600 has advantages such as good low altitude and low-speed performance, high firefighting and rescue efficiency, stable takeoff and landing during surface flight, wide range of mission execution, leading independent technology, and comprehensive localization support, filling the gap in China's aviation industry in this field. Industry experts point out that as the core of high-end manufacturing, large-scale sea and air equipment is an important area for implementing innovation driven development strategies and an important support for building a manufacturing powerhouse. The level of development in this field often determines the competitiveness of the entire industry chain. China has comprehensively broken through the key core technology of large-scale amphibious aircraft development through the independent development of AG600 aircraft, fully established a proprietary technology system for large-scale amphibious aircraft, and driven independent innovation, research and development, and independent guarantee in the civil aircraft industry chain and supply chain. ”Huang Lingcai, the chief designer of the AG600 series, said that the AG600 has achieved 100% domestic independent matching of the entire aircraft body structure, engine, and key systems. Currently, the resilience of the manufacturing industry is further enhanced in unfavorable external environments, and the connection between manufacturing and technological innovation is becoming closer. ”Zhu Minghao, Executive Director of the China High end Manufacturing Research Center at Beijing Jiaotong University, stated that on the one hand, the effective supply of innovation continues to strengthen, supporting the smooth breakthrough of a number of bottleneck products in the equipment field. Some key areas have already formed a relatively complete industrial chain; On the other hand, new products and achievements in the manufacturing industry continue to emerge, and intelligent manufacturing integrates new scenarios and formats, which not only promotes the improvement of major equipment production efficiency, but also supports the application and iteration of new technologies. Data shows that in the first quarter, nearly 70% of the key products in China's equipment industry achieved an increase in production. From the perspective of segmented industries, the development of land, sea, and air power equipment continues to improve, and the intelligent equipment industry is developing rapidly. In the shipbuilding industry, backbone shipbuilding enterprises are basically at full capacity. Industry experts believe that China's equipment industry is achieving high-quality development through intelligence, greening, and integration, and will open up even greater imagination in the future. For example, the cruise industry is known as the "golden industry floating on the sea", and the design and construction of cruise ships can bring a 1:14 driving force to related industrial chains such as shipbuilding, homeports, retail, and finance; The smart fishery large-scale breeding factory ship will comprehensively promote the coordinated development of feed processing, cold chain logistics, aquatic intensive processing and other supporting industrial chains. As a milestone in the commercialization of manned spaceflight, the Qingzhou cargo spacecraft introduces the concept and technological means of commercial spaceflight, promoting the rapid iteration and application of new ideas, devices, and materials in the aerospace field. The AG600 will become the "leader" of the domestic aviation emergency rescue equipment system, exerting a huge driving force in areas such as materials and components, avionics systems, and airworthiness standard systems.
