It may be the first approval of the Chinese high -speed military project, and the Chinese scientist team concludes the terrestrial exam of an ultra -high -speed turbo jet that can withstand its own high -speed “Blackbird” military aircraft. Ta.
Ultrasonic SR-71 “Blackbird” fighter is famous for its fastest operation aircraft at the maximum cruise speed of Mach 3.2. It was also the fastest jet -driven reconnaissance machine known for navigating an unparalleled airspace. The aircraft retired in 1999 just before the turn of the century.
Researchers at the Solar National Research Institute, one of the top aerospace engine research facilities in the southwestern China, have been steadily operated in the southern part of Hong Kong using state -of -the -art artificial intelligence technology. The ground test of the turbine engine has been completed. A Chinese morning post claimed.
This lab, which leads the road on the break-through of China’s aerospace technology, is famous for innovative work on the TAIHANG series engine that power the most advanced fighters such as the J-20 and future next-generation Chinese fighters. is.
A project team led by researcher Ji Chunsheng claims that the engine has met the “100 % supply chain localization” standards in a report on the Chinese Journal Promotion Technology on January 16th. I am.
According to reports, China is working on commercial airliners that can reach super -speed and sensitive speed, which is the first confirmation of high -speed aircraft developed in China. In fact, if any report is being made, Chinese scientists are already making a huge leap in their development.

The SCMP report compared this Chinese ultrasonic aircraft with SR-71 Blackbird. However, there is currently no accurate role or information about the mission.
The United States has developed a blackbird and secretly infiltrated the enemy’s territory in an era ahead of satellites and drones. The lightning aircraft was able to cruise near the end of the universe and cover the missiles. The advantage of Mach 3 -speed than the ground -to -empty missile (SAMS), electronic countermeasures, and high -level flights.
However, China is aiming to develop a high -speed aircraft that is faster, cheaper, and can be operated. According to the SCMP report, “This project aims to build a faster and more advanced airplane than the legendary American SR-71 blackbird. Blackbird reconnaissance aircraft reach the speed of 3.2. There is a possibility, but he retired in 1999 due to high operating costs.

The development of this state -of -the -art high -speed aircraft focuses on the turbofan engine that moves it.
Chinese high -speed turbo jet engine
The dual mode design of the Chinese high-speed turbo jet engine is similar to the Blackbird J-58. This is a turbo jet engine with an after burner that increases high -speed thrust.
These engines compress the air using turbines for low -speed and effective combustion. During high -speed cruising, additional air inlet will open, air enters the combustion chamber directly, gaining higher thrust.
One of the major issues for engine designers was the PLA (PLA) requirements for a new aircraft in China to perform better than blackbirds in terms of speed and economy. For example, the team has revealed that the strict operating environment of the engine demand will put a considerable cap in the frequency and performance of the local central processing unit (CPU).
India is the top of the “sad list” of the abandoned sailor to avoid regulations, and has been denied workers.
JI and his colleagues have created a “enhanced high -Mach adaptive model” to improve the performance of the engine and “smart” in almost all operations. A paper explained in a paper to meet the “engineering application requirements”.
The team also said that it faced several issues in the development process. One of the notable issues was the gap between the status of the on -board computer engine and the actual situation. This can have a significant impact on engine control. The team writes as follows. “In the actual application, there is a deviation between the estimated output and the true output of the on -boardorial time model.”
This is mainly because the engine parts deviate slightly from the design value due to the uncertainty of manufacturing and installation.
In addition, the performance of the component can worsen over time. For example, the leak of engine oil caused by expanding space between components was a common problem for blackbirds. However, these problems may deceive computers.
The report has been greatly improved since the BLACKBIRD era, and the JI team has been using some research to collect error data and use it to increase the accuracy of the model. Masu.
At the same time, scientists have created a unique artificial intelligence algorithm that allows military processors to perform complex calculations quickly. The ground -based rigtesty has demonstrated the ability of the engine steadily and effectively for a long time.
“This model can prove the value of the engine characteristic parameters and health parameters online in real time, in real time, and can prove the high engineering application value,” Ji’s team wrote.

The report emphasized that China often tracks the west of jet engine technology because private jets do not have domestic production engines. However, according to publicly available data, Chinese scientists and engineers have made great progress in several important technologies, such as heat management, new blade materials, and overall engine design and manufacturing. I claim that there is.
“Last year, the Chinese government’s decision to impose export control on aircraft engine components technology and manufacturing equipment has made the Chinese aerospace industry dramatically in combination with the recent recent public test flights of the sixth generation fighter. He promoted the guess that he was.
In addition, Chinese companies have recently announced prototypes of next -generation ultra -speed commercial transport aircraft. This can be moved at 1x speed with Mach 4. According to a state -owned global Times report, the aircraft will fly in 2026.
On the other hand, the United States is also a commercially available super-ton air aircraft (X-59), an experimental aircraft of NASA’s Quetz, which can go to super-sound speed without generating sound like the Sonic boom or loud lightning. I am working on it. sound.
