China's high-tech, energy-efficient aircraft engines showcased at Zhuhai Airshow

China's domestically developed aircraft engines are capturing the limelight at the ongoing 15th China International Aviation and Aerospace Exhibition in the southern coastal city of Zhuhai, wowing visitors with their cutting-edge technologies and energy-efficient designs.

The exhibition kicked off in Zhuhai City of Guangdong Province on Tuesday, showcasing the latest in aircraft, spacecraft, and weaponry, along with impressive aerial performances.

Among the attention-grabbing exhibits, a number of innovative aircraft engines are demonstrating China's gains in this competitive and fast-evolving industry, spanning the gamut from fighter jet engines to those for civilian aircraft.

As an important aviation enterprise, Aero Engine Corporation of China, or AECC, is engaged in the development, production and maintenance of aircraft engines, gas turbines, and more. Its turbojet engines, turbofans, and turbo-shafts have been widely installed in various types of military and civilian aircraft.

The company's star product, the AEF1200, debuted at the event, catching eyes with its sheer size. It is the country's first self-developed high bypass ratio dual rotor turbofan engine, a highly efficient type of jet engine that uses two sets of rotating blades to compress air, with most of the air bypassing the engine core to create thrust more quietly and with better fuel efficiency. This design will help China's large airplanes fly farther on less fuel while keeping engine noise down.

AECC also displayed new engines designed for helicopters and drones, which are expected to be increasingly important in coming years.

"Our AES100 engine is an advanced turbo-shaft engine independently developed by AECC in response to the national call for the development of the low-altitude economy, which is energy-saving and environmentally friendly. It is equipped with a very useful health-monitoring system. So, its stability and reliability can also be assured. The AEP100 is a 900-kilowatt turboprop engine developed by us using a turboshaft engine. It can also be used in drones, business jets, and trainer aircraft," said Liu Jie, a staff member at AECC.

Since its launch, the event, also known as Airshow China, has been one of the top five airshows worldwide. This year, nearly 900 enterprises from 47 countries and regions are participating, with 149 of them global attendees.

The total profits of light industrial enterprises above the designated size in China (firms with annual business revenue of at least 20 million yuan) exceeded one trillion yuan (about 138.67 billion U.S. dollars) in the January-September period, according to the China National Light Industry Council.

Driven by supportive policies aimed at boosting the consumption, such as consumer goods trade-in programs, China's light industrial economy has been operating smoothly. The domestic and foreign trade markets are expanding steadily, and investment is recovering rapidly.

In the first three quarters, the operating income of light industrial enterprises above the designated size reached 16.52 trillion yuan, with profits totaling 1.02 trillion yuan, a year-on-year increase of 7.2 percent.

Among them, the output growth rates for household freezers, air conditioners and refrigerators stood at 14 percent, 8 percent, and 7.5 percent, respectively, and industries such as papermaking, batteries and furniture saw profits maintaining a double-digit growth.

The market size of light industry expanded steadily, with exports reaching 682.16 billion U.S. dollars, up 2.6 percent year on year.
