This is considered the largest airspace crossing of China that Taiwan has recorded so far. Although there has been no comment from Beijing, according to Reuters, this information comes after G7 leaders issued a joint statement last Sunday in which they criticized China for a series of issue, emphasizing the importance of peace and stability in the Taiwan Strait. Beijing later condemned the joint statement as “defamation”. Over the past several months, Taiwan has continuously released information about a series of incidents of Chinese air force entering its airspace, mainly concentrated in the southwest area of ​​the air defense identification zone. The most recent incident involved 14 J-16s, six J-11s, and four nuclear-capable H-6 bombers, along with anti-submarine and electronic warfare aircraft. and early warning; according to the Taiwan Defense Agency. The incident has just been reported to be the largest-scale incident since Taiwanese authorities began publicly reporting violations of their ADIZ since last year, breaking the previous record of 25 Chinese aircraft. entered Taiwanese airspace on April 12. Taiwan’s Defense Ministry added that its fighter jets were deployed to intercept and repel the Chinese aircraft, while missile systems were deployed at the ready. The Chinese Ministry of National Defense has not yet commented on this information. China has previously asserted that such missions are necessary to protect the country’s sovereignty and deal with “collusion” between Taipei and Washington. The United States, like most countries that do not have formal diplomatic relations with Taiwan, keeps a close eye on events that raise tensions with Beijing.

Engine problems caused China’s J-20 production to be delayed. Photo: SCMP The South China Morning Post (Hong Kong, China) reported that the country has developed a new coating material for the engine, contributing to solving technical flaws and increasing the thrust of the engine. The new coating material was designed by Yuanke Energy-saving and Environmental Technology Development Co., Ltd. in Hebei Province. This material can withstand temperatures of 1,800 degrees Celsius and helps protect the engine from the risk of corrosion while ensuring higher power. The current widely used military aircraft engine in China is the WS-10, which can withstand a temperature of about 1,470 degrees Celsius and the improvement can make a significant contribution to increasing the engine’s output power. . The propeller has long been considered the “Achilles heel” of China’s military aircraft engine development program. An obvious example is the delay in the development of a new engine that slows down the production of China’s fifth-generation stealth fighter J-20. Chinese scientists have spent years trying to get the WS-15 engine designed for the J-20 to work, but still have problems with the propellers that constantly heat up at high speeds. As a result, the Chinese Air Force is forced to use Russian-made engines or an improved version of the WS-10. Both of these engines are said to reduce the combat and stealth capabilities of the fighter. The new coating material consists of a fullerene, a ball-shaped carbon molecule. The manufacturer says the coating has a “2,000-hour lifespan” and is resistant to corrosion. The special thing is that this material can withstand the heat required for the J-20 to operate at its maximum capacity.
