##China’s Largest Unmanned Transport Aircraft Makes Successful Maiden Flight
**KeyWords:** Drone, Maiden Flight, Aero-engine
**Shaanxi, August22, 2024** – China Aviation Engine Group Co., Ltd. announced today that its independently developed 900-kilowatt turboprop engine AEP100-A powered the successful maiden flight of the SA750U large unmanned transport aircraft in Shaanxi. Thismarks a significant breakthrough in China’s drone technology and injects strong momentum into the development of China’s aero-engine industry.
The SA750U large unmanned transport aircraft is China’s first large unmanned transport aircraft witha payload exceeding 3 tons. Its successful maiden flight fills the gap in the domestic large unmanned transport aircraft sector. The aircraft is entirely independently developed by China Aviation Engine Group, equipped with the AEP100-A turboprop engine. It boasts high-temperature and high-altitude adaptability, and adopts three-dimensional aerodynamic design and unit design technology, providing powerful thrust while effectively improving fuel economy and overall operational efficiency.
The AEP100 series turboprop engine can be fitted to 2-6 ton general aircraft or 3-10 ton drones, achieving a comprehensive performance that meets the international advanced level of its class. This signifies that China has the ability to match international advanced levels in the field of aero-engines, laying a solid foundation for future development.
The SA750U large unmanned transport aircraft can be applied to regional aviation logistics, unmanned material delivery in specific scenarios, forest and grassland firefighting, and other fields. It will bring revolutionary changes to China’s aviation logistics, emergency rescue, agricultural production, and other sectors.
The successful maiden flight is not only a significant milestone in the development of China’s drone technology but also demonstrates the breakthroughprogress China has made in the field of aero-engines. In the future, with the continuous development of China’s drone technology and the continuous expansion of application scenarios, China’s drone industry will usher in a broader development prospect.
