Biden watched with tears in his eyes! China's engine "overtook in a corner", and foreign media were shocked by breaking the US blockade
After the second industrial revolution, European and American countries monopolized a large number of technologies in the field of heavy industry, such as armored machinery, engines, auto parts, major aviation parts and other products.
But after decades of economic development, the scale of China's manufacturing industry has gradually increased, and it has also begun to be monopolized by heavy industry and core technology research and development"Overtaking in corners", Biden is very heartbroken!
In essence, whether it is an automobile engine or an aero engine, Germany has absolute strength in this field, but under the sanctions of the United States and the United States, China is obstructed by the United States, and it is difficult to customize the import of products in this field.
Due to U.S. restrictions, Ukraine's Madasich and Britain's Rolls-Royce are unable to provide basic technology to Chinese companies, even if they are about to go out of business, which seriously hinders the development of China's aerospace industry.
In the face of such first-class measures, Chinese companies have to carry out independent research and development in the sense of strategic deployment as in the semiconductor field, but fortunately, many years have passed, and China's engine has not made a breakthrough.
According to the launch of the Chinese aviation sector"A great power is a heavy weapon. Touring"The AEP500 engine, independently developed by China, is used as a new generation of main components for China's MA700 high-speed turboprop regional aircraft.
However, at the beginning of the design of the MA700, there was no plan to use the domestic AEP500 engine, because this engine had not been successfully developed at that time, so the original plan of Xifei Industry was to use the PW150C turboprop engine of Hewlett-Packard of Canada.
At that time, this PW150C turboprop engine was considered to be the best engine in the world and the most suitable engine for the MA700, and its performance was very good, even the T56 series turboprop engine produced by Allison in the United States was difficult to surpass the former.
However, Lao Mei was not willing to let its performance match the water, and chose to intervene again, and finally took China's PW150C turboprop engine order but did not arrive, which also led to the postponement of the debut of the new boat 700.
In October 2022, China's AEP500 engine officially rolled off the assembly line, and its performance surpassed that of the T56 series turboprop engine in the United States and the PW150C turboprop engine in Canada.
The AEP500 engine has a power of 5,000 kilowatts, adopts a three-rotor structure, and after being installed on the MA700, an 8-blade propeller is installed for the first time, which makes the MA700 exert considerable performance power.
Of course, in addition to the AEP500 engine of the MA700, the C919 Yangtze River 1000 engine used to replace the LEAP-X1C engine imported by CFM US-France joint venture has gradually entered the final stage of research and development.
In terms of performance, the thrust of the Yangtze engine is 13 tons, compared to the LEAP-X1C engine 13The thrust of 7 tons is slightly insufficient, but it is certainly not a big shortcoming to use on the C919.
However, the Yangtze River 1000 engine, as a domestic alternative engine to C919, is the most important sign is the successful development and successful realization"De-beautify"At the same time, breakthroughs have also begun to be made in the development of essential components for China's large passenger aircraft.
As reported by foreign countries, China's independent research and development achievements have broken the situation of the US blockade, which undoubtedly brings new worries to Biden.
But as long as China insists on independent research and development, I believe that there will be better results in research and development in the field of engines, because it is only a matter of time before armored machinery technology surpasses the level of Europe and the United States!
