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.

The highly-anticipated biennial aerospace trade event, also known as Airshow China, will run through Sunday. It has attracted 1,022 companies from 47 countries and regions to showcase their star aviation and aerospace products, including a record number of products being debuted to the public at the event.

The multilateral system is "under attack" amid global turmoil, President of the 80th UN General Assembly Annalena Baerbock warned in her remarks on Wednesday.

In her briefing on the priorities for the resumed 80th Session of the General Assembly, the UNGA president noted that the current multilateral system does not collapse all in a sudden, but "crumbles piece by piece" in divisions, compromises, and lack of political commitment.

The president called all the UN member states to defend the UN Charter and international law and promote cross-regional cooperation.

She also urged to push forward the work of the UNGA on certain critical issues with a strong majority, rather than an absolute consensus among all member states. Such act is not a failure of multilateralism, but "an affirmation of it," she said.

The foundational principles of the institution should not be eroded by appeasement, she said, calling the member states to show courage, leadership, and responsibility at the UN's "critical make-or-break moment."

"The UN needs you. Your support, your leadership, your principle, stand, your cross-regional cooperation, if we are to preserve and modernize this institution, if we are to make it, rather than break it," she said.
