价值数千万国产发动机，重大高风险试验一次成功！这15秒，所有人都捏把汗

Core Insights - The AES100 engine, China's first fully independent and internationally competitive 1000 kW civil turboshaft engine, successfully powered the 6-ton tilt-rotor UAV, Lanying R6000, in its maiden flight in Sichuan [1][5] - The development of the AES100 engine was likened to a world-class challenge, with the research team overcoming significant hurdles over five years, including a critical 15-second test [1][3] Development Challenges - The most significant challenge during the development was the engine's overall compatibility test, a high-risk airworthiness test that had never been conducted for civil engines in China before [3] - The test involved a dangerous procedure where the power transmission shaft was intentionally severed at maximum engine speed, causing the turbine blades to experience approximately 5 tons of centrifugal force and potentially fly off [3] - The team meticulously planned the test from 2018, completing various stages of testing each year leading up to the successful trial in September 2023 [3][5] Test Success - On September 10, 2023, the team successfully executed the critical test, where the turbine blades detached as designed, and the engine safely shut down within the required 15 seconds without causing any catastrophic failures [5] - This achievement set a new record for high-risk civil turboshaft engine testing in China, eliminating the most significant obstacle in the airworthiness certification process for the AES100 engine [5] Future Prospects - The successful development of the AES100 engine fills a significant product gap and reduces reliance on imports, with plans for future development focusing on series production, platform integration, and industrialization [5]
