Core Viewpoint - The AES100 engine, a domestically developed 1000 kW class advanced civil turboshaft engine in China, has received a production license and signed sales contracts, marking a significant milestone in the country's aviation engine industry [1][3]. Group 1: Engine Specifications and Applications - The AES100 engine is characterized by high safety, good economy, easy maintenance, and wide environmental adaptability, suitable for 5-6 ton dual-engine helicopters and 3-4 ton single-engine helicopters, as well as tilt-rotor aircraft for various missions including transport, sightseeing, and rescue [3]. - The production license indicates that the industrial manufacturing capability of the AES100 engine has received airworthiness approval [3]. Group 2: Future Developments and Contracts - In addition to the production license, China Aviation Engine Group has signed sales and leasing contracts for the AES100 engine, which will serve as the core power unit for the 6-ton tilt-rotor unmanned transport platform "Lan Ying R6000," with delivery planned for 2026 [6]. - The industry is rapidly advancing towards a full spectrum of general aviation engines, with multiple domestically developed advanced aviation engines expected to achieve their first flights and certifications within the next year [6]. Group 3: Additional Engine Projects - Based on the AES100, researchers have developed the AEP100, a 900 kW class turboprop engine designed for 3-10 ton drones, which has completed its first flight and meets international performance standards for its class [6]. - A 200 kW class turboshaft engine, the AES20, is also under development for light aircraft, with expected first flight by the end of 2025 and airworthiness certification by 2026 [6].
