China's first homegrown advanced civil aircraft engine unveiled at Zhuhai Airshow

The Aero Engine Corporation of China (AECC) officially launched China's first self-developed advanced civil turboshaft engine AES100 during the ongoing 15th China International Aviation and Aerospace Exhibition in the southern coastal city of Zhuhai on Wednesday.

The AES100 engine is mainly employed in civil helicopters and has gained its type certificate from the Civil Aviation Administration of China (CAAC).

The take-off power of the turboshaft engine AES100 turboshaft engine is no less than 1,000kW, and it can be equipped with a 5-6 tonne twin-engine helicopter or a 3-tonne single-engine helicopter, according to its developer AECC.

The AECC said the engine has the advantages of high efficiency, low fuel consumption, long lifespan, high reliability, and meets the needs of a wide range of fields.

Featuring advanced design, technologies, and a management system, the AES100 engine can operate safely and steadily under complex conditions including freezing weather, heavy rain, and a strong electromagnetic environment. Helicopters powered by this engine can perform a variety of tasks, including patrol, rescue, sightseeing, as the engine is highly adaptable and can be used in diverse scenarios, said Li Gaiqi, chief designer of AES100.

Moreover, the ASE100 engine can be upgraded into turboprop engine, turbofan engine, and ground-based lightweight gas turbine to power small and medium-sized turboprop aircraft, jet business aircraft, and ground-based mobile power stations.

In addition to AES100, a total of 10 general aviation power products were also showcased by AECC at the launching event during the 15th China International Aviation and Aerospace Exhibition.

South Korean President Lee Jae Myung said on Wednesday that Seoul firmly adheres to the one-China principle, in comments made ahead of his upcoming state visit to China.

The remarks were made in an interview with China Media Group (CMG). The visit is scheduled for Jan 4–7.

"The consensus reached between governments of the Republic of Korea and China when diplomatic relations were established continues to be the fundamental principle governing our relations, and its effectiveness remains steadfast. I want to clearly state that the ROK has always adhered to the one-China principle. Maintaining peace and stability in regional matters, including in Northeast Asia and concerning the Taiwan issue, holds significant importance to us," said Lee.

"The foundational relationship between the ROK and China was established on a very principled and fundamental basis from the beginning. It is clear that the ROK government has always adhered to this position and has never wavered from it. I believe that the sound development of ROK-China relations depends on both sides fully respecting each other's core interests and being mutually tolerant of each other's positions. In this context, we will, as always, uphold the one-China principle as the Taiwan issue is China's most fundamental concern," he said.
