China's next-gen turbine blade promises supercharged jet power, more longevity
A recently granted patent in
China's aeronautics industry has signalled a significant leap in the development of a critical component for jet engines – a next-generation self-cooling turbine blade that could mean critical advantages for both the country's military and civilian aircraft.
The patent outlined a new method for producing alloy turbine blades capable of withstanding temperatures up to 15 per cent higher than existing versions. The improved heat resistance was expected to deliver
greater engine thrust , better fuel efficiency, and longer service life.
The Beijing Institute of Aeronautical Materials under Aero Engine Corporation of China (AECC) received the patent for advanced turbine blade manufacturing in late April.
AECC has led Chinese research on military engines for fighter jets such as the
J-10CE , the same ones used by Pakistan's military – which Beijing recently confirmed shot down Indian jets – as well as civilian plane engines like the CJ1000A and CJ2000. The latest innovation helped to cement its leadership in high-performance propulsion technologies.
According to the China National Intellectual Property Administration, the patent, which was first filed in October, was co-developed by AECC and Handan Xinxing Special Steel Tube Company in northern China's Hebei province.

High-temperature alloy turbine blades are a critical component in modern jet engines, directly influencing thrust output, fuel efficiency and reliability. Conventional turbine blades tend to degrade from prolonged exposure to extreme heat, restricting overall engine performance. The newly patented method aims to overcome this limitation by improving the thermal tolerance of the blades.

Another brick in the wall: world's largest Legoland opens in Shanghai next month
Trial operations started on Friday at the world's largest Legoland theme park in Shanghai, as the city presses ahead with its goal to boost its status as a major global tourist destination The US$550 million Legoland Shanghai Resort, located in the southwestern Jinshan district, could attract up to 2.4 million visitors a year once it officially opens on July 5, according to estimates by local government officials. The 318,000-square-metre entertainment complex – featuring eight themed areas, 75 interactive rides and a 250-room hotel – has used more than 85 million 'Lego bricks'. 'It will be yet another world-class amusement park that adds lustre to Shanghai's tourist industry,' said Li Wenjie, CEO of Shanghai Yaheng International Travel. 'The Legoland Resort's synergy with the city's Disneyland and Haichang Ocean Park will offer tourists enjoyable, unique experiences that are not available in any other Chinese city.' Children pose for a photo with a mascot as they visit Legoland Shanghai Resort ahead of the theme park's opening on July 5.

As Trump struggles to secure trade deals, has Beijing's hand been strengthened?
The United States failed this week to reach a tariff deal with Japan, a key Pacific Rim ally, and has threatened to notify multiple countries of new duty rates on imports after talks with only one, the United Kingdom, have shown any results. Those developments, which made the US look weak in the short term, should prompt China to take a harder line with Washington on reaching a deal, analysts said. China, the world's second-largest economy, was hit especially hard by US President Donald Trump on April 2, which he dubbed 'Liberation Day' , when he raised duties on Chinese imports to more than 100 per cent. Citing concerns over US trade deficits, he also imposed double-digit tariffs on imports from many other Asian nations. Country-specific 'Liberation Day' tariffs were put on hold for 90 days the following week – until July 9 for most countries – pending trade negotiations. Following talks in Switzerland in early May, those on China were also paused for 90 days, until August 12. Beijing's negotiators would draw strength from the US threat to notify trading partners of new duties and the lack of a US-Japan deal because both showed it was hard for Washington to get what it wanted through talks this summer, said Chen Zhiwu, chair professor of finance at the University of Hong Kong. 'These kinds of threats should embolden the Chinese negotiators because it's a sign of desperation,' Chen said.
