"Largest in the world""World's first"
"Important breakthrough"
This week, major national heavyweights have been delivering good news continuously
China has achieved outstanding performance in multiple fields
Important breakthrough!
China's self-developed 3D printed engine completes its first flight
Recently, the 3D printed ultra-simple turbojet engine independently developed by China Aviation Engine Group successfully completed its first flight test, marking an important breakthrough in the engineering application field of 3D printed engines. The flight test lasted 30 minutes, with a flight altitude of 6,000 meters and a maximum speed of 0.75 Mach. The engine operated in full status, with all working parameters normal.

The success of this single-engine flight test indicates that the reliability of the engine under higher flight altitudes and more complex environments has been further verified, testing the compatibility between the engine and the aircraft. It can provide a new power solution for platforms such as cruise missiles, drones, and target aircraft, showing good application prospects.
According to the introduction, the engine uses 3D printing manufacturing technology, with more than three-quarters of the weight of the parts being manufactured using 3D printing, greatly reducing the number of parts and achieving the design goals of lightweight and high performance.
A "super kite" of 5,000 square meters
The world's largest high-altitude wind-catching umbrella successfully opened
On November 12, the core equipment of China's first national key R&D plan for high-altitude wind energy has made new progress!
The world's largest 5,000 square meter high-altitude wind power catching umbrella successfully opened at the test site in Alashan Left Banner, Inner Mongolia, completing all the planned test content and successfully achieving the aerial retraction of the umbrella. This marks a solid step forward in the engineering application of China's high-altitude wind power generation technology.
This large "kite" looking like can capture wind energy above 300 meters, then pull the ground generator to rotate and generate electricity through this traction cable. This test achieved the opening and retraction of both 5,000 square meter and dual 1,200 square meter wind catching umbrellas.
High-altitude wind energy, which is still not yet widely developed, is an uncharted area of new energy with advantages such as high wind speed, stable wind direction, and high wind energy density, and it holds great potential. Currently, there are mainly two technical routes, land-based and air-based. Air-based high-altitude wind power generation involves mounting lightweight wind turbines on lightweight flying vehicles to generate electricity in the air. This test is about land-based high-altitude wind power generation, which uses a working umbrella that is deployed in the air to capture wind energy and pull the ground power generation system to work and generate electricity.
Largest and most advanced
The lighthouse ship "Haixun 176" officially joined the fleet
On November 13, the large lighthouse ship "Haixun 176", independently designed and built by China, was officially commissioned to the South China Sea Navigation Assurance Center of the Ministry of Transport. This ship is currently the largest and most advanced lighthouse operation ship in China's transportation system.
After three years of construction, the ship has a total length of 75.2 meters, a beam of 14 meters, a full load displacement of 2,360 tons, a range of 5,000 nautical miles, a maximum speed of over 15 knots, and can safely navigate under 6-level sea conditions and safely operate under 4-level sea conditions. With its long-range capability, the ship can support the deployment and emergency repair of offshore lighthouses.
After the commissioning of the "Haixun 176", it will be managed and used by the Haikou Lighthouse Office, responsible for lighthouse deployment, maintenance, and navigation management in the South China Sea area. It focuses on serving the Qiongzhou Strait and Sansha waters, enhancing the capabilities and level of maritime navigation assurance services in the South China Sea.
Maximum parameters, minimum coal consumption
The world's first 650℃ efficient coal-fired power unit makes progress
The world's first 650℃ efficient ultra-supercritical coal-fired power boiler recently completed the first concrete pouring at the Huaneng Yuhuan Power Plant, entering the comprehensive construction phase. This boiler is the first equipment approved by the State Administration for Market Regulation to enter the sandbox test after the implementation of China's special equipment safety sandbox regulatory system.
This boiler is the first in the world to raise the steam temperature of coal-fired power plants to the highest 650℃ globally. It uses a series of domestically developed high-temperature alloy materials, breaking through the "neck" problem of high-temperature alloys, realizing complete autonomous control of key high-temperature material technologies. It is a significant breakthrough in China's high-temperature new materials and new technologies for clean and efficient coal power utilization.
Once completed, this boiler will set new records for the highest operating parameters and lowest coal consumption of global thermal power units.
