Recently, the reporter learned from China Aero Engine Group Co., Ltd. that the company's independently developed and internationally competitive 900 kW turboprop engine AEP100-A helped the SA750U large unmanned transport aircraft successfully make its maiden flight in Shaanxi. The AEP100-A turboprop engine is designed by AVIC Hunan Power Machinery Research Institute and manufactured by AVIC Southern Industry Co., Ltd. It has excellent high-temperature and high-altitude adaptability. This engine adopts advanced three-dimensional aerodynamic design and unit design technology, which has good safety, reliability, and maintainability. While providing powerful power to the aircraft, it can significantly improve fuel economy and enhance the overall operational efficiency of the aircraft. The SA750U large unmanned transport aircraft is China's first large unmanned transport aircraft with a load capacity of over 3 tons, which can be applied in regional air logistics, unmanned material delivery in specific scenarios, forest and grassland firefighting and other fields. It is understood that the AEP100 series turboprop engine can be equipped with 2-6 ton general-purpose aircraft or 3-10 ton unmanned aerial vehicles, and its comprehensive performance has reached the advanced level of the same level in international active service. The successful maiden flight of the SA750U large unmanned transport aircraft marks the second successful installation of a new aircraft platform with AEP100 series turboprop engines, following the installation of Rainbow and AVIC drones. This is not only an important milestone in the development process of this series of engines, but also fully demonstrates that this series of engines has gained widespread market recognition.
