In today's world, the aerospace industry has become a symbol of a great power, and as the "heart" of a big country, its performance, safety and efficiency will be greatly affected, but from the point of view of shortcomings, our aircraft still have deficiencies in engines.
However, more than 40 years later, with the country's economic and technological progress, it took them 20 years to solve this "weakest country"! Moreover, the "Chinese heart" is also aimed at international standards!
Many people may ask: What is this "Chinese heart"? In fact, it is called the turboshaft "Jade Dragon" aircraft engine.
So, let's take a look at China's shortcomings in the engine.
Looking back at the early 1980s, China began to embark on the road of high-end aero engine research and development, but because China's research on aero engines is still relatively backward and relies heavily on foreign technology, China has always been a follower in the aerospace field, and it is difficult to get out of the dependence on foreign engines.
The disadvantages are:
The first is the lack of sufficient scientific and technological strength, which is a big weakness in China's aircraft engine industry. In recent decades, there is a big gap between China and the world's advanced level in some important space engine fields. Especially in the new materials, turbomachinery design and combustion technology, there are significant defects, so that the technology of domestic aircraft has never been able to reach the world's leading level.
Secondly, the R&D system is not perfect, the long-term lack of systematization and synergy, and the lack of close cooperation among R&D institutes have resulted in the lack of systematization and coordination of R&D work in China, resulting in the R&D results not being a strong driving force and unable to achieve sustainable development.
In addition, the structure of China's aircraft engines is very complex, and the backwardness of testing and testing methods has caused difficulties in the research and development of China's aircraft engines, and has also brought many uncertainties.
In addition, because China is facing huge market competition, therefore, China in the global market, countries with independent R&D strength, will gain more say in the future competition, while China has been controlled by foreign companies, which affects its competitiveness in the world, thereby affecting its future development.
The shortcomings of China in the field of aircraft engines are summarized. It must be admitted that only by overcoming this shortcoming can China's aerospace industry become the world's No. 1 in independent innovation and international competition.
After knowing the above, let's continue to talk: what shortcomings and deficiencies did the introduction of the "Jade Dragon" turboshaft aircraft engine fill in the previous engines in China?
The first problem: the lack of propulsion has become the biggest problem with this old engine. The limited propulsion capacity of the aircraft affects the working range and working range of the aircraft, and becomes a bottleneck for its use under complex conditions. The new generation of "Jade Dragon" turboshaft engine is expected to greatly improve the maneuverability and combat effectiveness of the aircraft, thereby bringing greater power to it.
The second point: Outdated engine designs lead to lower fuel utilization, higher operating costs, and more fuel required. In order to improve fuel efficiency and reduce dependence on energy, new generations of aerospace vehicles often use more advanced combustion technologies, lighter materials, and higher performance.
The third level: the reliability of old aero engines is also a huge risk, and the frequent occurrence of failure and maintenance requirements will seriously restrict the service life of the aircraft, therefore, the reliability of the new generation of aerospace aviation equipment will be greatly improved, and it will be applied to the aerospace field.
The fourth level: from the perspective of technology application, the traditional engine lacks the effective integration of digital and intelligent technology, which makes its development in the fields of intelligent monitoring and adaptive control, so as to improve the response, efficiency and adaptability of the engine.
The fifth level: the diversification of flight missions proposes a higher adaptability of the engine. Older engines may not be able to adapt to the flexibility required by a variety of situations and missions. The new generation of engine is expected to better cope with a variety of complex environments such as high-altitude patrol, high-speed climbing, and high-speed maneuvering after structural optimization and flexible improvement.
In general, the successful research and development of the "Yulong" turboshaft airliner will fill China's shortcomings in terms of technical level, research and development system, experimental verification and competitiveness in the global market, and lay a good foundation for China's future development.
