The gap between China and the United States is widening? The Turbofan 15 is inferior to the XA100 in terms of thrust, fuel consumption and high-speed performance!
The most important parameters in the aero engine are pressure, fuel consumption and other parameters, so when the comprehensive evaluation of a certain type of aero engine is carried out, the comprehensive evaluation is generally based on this parameter.
China's latest aero engine - turbine 15 has attracted worldwide attention, and not long ago, the United States launched an adaptive adjustable cycle engine called XA100.
According to official figures, the American engine is somewhat larger than the engine of the Turbo 15, but the fuel consumption is a little less. At the same time, many people are worried that our engines are no longer up to date.
The adaptive recirculating engine (also known as the variable recirculating engine) is a new type of pneumatic actuator that can optimize various performances according to different flight conditions.
Therefore, the core of the approach is that it can be dynamically adjusted according to the actual situation, so as to maximize fuel efficiency, pollutant emission reduction, and adaptive adjustment.
To put it simply, when more thrust is required, more fuel is used to get more thrust; In cases where the thrust required is small, the fuel required is reduced. This method can bring more thrust to the engine with reduced fuel consumption.
However, due to the certain operating conditions of conventional aero engines, it is difficult to take into account all factors, and at the same time, it will also have an impact on engine pressure, fuel consumption and other parameters.
Because there are great differences in terms of basic technology, working mechanism, etc., the two are not people of the same era, and there is not much comparison, so the gap between J-15 and XA100 is not obvious.
Moreover, many factors will have an impact on the aircraft, and the engine is only one of them, and the shortcomings of the engine itself can be compensated for by other advantages. The concern is not that the gap is being ignored.
Some time ago, due to the leading position of the United States in this field, the United States already has a fairly high level of science and technology. After all, in terms of aviation engines, the development of our country is still relatively slow, and now the pace of scientific and technological development is still very fast.
In various fields, we are shortening the distance to the world's major space engines. The XA100 is the world's first self-developed adjustable-cycle engine, but it is possible to implement this technology in the future.
At present, its basic theory has been basically established, and the corresponding experimental research has been carried out, and it is facing problems such as mechanism research, process research and development, and even product development. This is a long time, but with our previous scientific and technological strength, it will not be too long to catch up.
In fact, we have caught up and taken the lead in many aspects of technology and technology. Taking the shield as an example, at the beginning, we only imported from abroad, which was not only expensive, but also difficult to obtain the latest technology. In the case of protective equipment, for example, we had to import it from abroad at the beginning, which was not only costly, but also difficult to obtain the latest technology.
Then there's high-speed rail technology. Japan's next-generation high-speed rail line is considered to be the earliest high-speed rail line, and its technological level has reached a fairly high level. Ten years ago, when we were manufacturing high-speed rail, we were still looking for scientific and technological support from abroad. At present, China's high-speed rail products are exported to all over the world and have been favored by many overseas customers.
It can be seen that catching up is not as difficult as imagined, if you are willing to do it with your heart, it is only a matter of time before you catch up and even surpass.
Postscript. As it is said on the Internet: "Until the dust clears, we are the real dark horses". Although the U.S. has now made great strides in the variable cycle engine, we are not left behind, and we still have a lot to chase until we have the final victory.
