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.

Chinese stocks closed higher on Tuesday after the U.S. Supreme Court ruled against the broad tariffs implemented by the Trump administration last year, putting China among the countries set to face lower levies on exports to the U.S., reported Timothy Pope, a market analyst for China Global Television Network (CGTN).

Tuesday marks the first trading day after China's nine-day Spring Festival, or Chinese New Year, holiday.

"The markets did pretty well. Galloping into the Year of the Horse, the Shanghai Composite Index was up more than 1.2 percent at one stage. It's did moderate those gains a little by the end of the session, closing 0.9 percent higher," said Pope.

In addition to the benchmark Shanghai Composite Index, the Shenzhen Component Index closed 1.36 percent higher at 14,291.57 points.

The analyst attributed the increases largely to the U.S. Supreme Court's tariff ruling, which said on Feb 20 that U.S. President Donald Trump's sweeping levies under the International Emergency Economic Powers Act (IEEPA) meant for use in national emergencies were illegal.

"While pretty much everything in China stops for the Spring Festival, the rest of the world didn't. We had that U.S. supreme court ruling on Donald Trump's tariffs being effectively illegal, following which, of course, he threw his toys out of the pram and found a new way to put tariffs on the whole world for 150 days. I guess it wouldn't be another year of the Trump presidency without added tariff drama. But all the analysis I've seen so far seems to agree that this could be a good thing for China -- that the effective rate of tariffs on Chinese exports to the U.S. will go down as a result. That certainly seemed to be the market consensus today. We saw a lot of export-facing industries gaining ground. Consumer electronics stocks had been up by more than two percent around the lunchtime break. They closed about one and quarter percent higher -- so some quite strong performances there," Pope said.
