Technical difficulties
Compared with developed countries, there is a big gap between China and developed countries in terms of key technologies of aero engines.
Developed countries pay attention to the R&D and application of advanced materials in the field of aero engines to improve the performance and efficiency of engines. These advanced materials include superalloys, composite materials, and more. Superalloys can maintain stable performance in high-temperature environments, improving the operating temperature and thrust ratio of the engine. Composite materials have the advantages of light weight, high strength, corrosion resistance, etc., which can reduce the weight of the engine, improve fuel efficiency and flight performance. In contrast, China is lagging behind in the research and development of advanced materials, and needs to increase investment and research efforts.
Turbomachinery is the core component of aero engines, which directly affects the performance and efficiency of engines. Developed countries have accumulated rich experience and advanced technology in turbomachinery design, which can achieve higher speeds, higher efficiency and lower noise. However, there is still a big gap in the design of turbomachinery in China, and it is necessary to further strengthen research and technical research.

These gaps make it difficult for China to compete with developed countries in terms of key technologies for aero engines. However, with the continuous development of China's economy and science and technology, China is gradually increasing its investment in the research and development of key technologies for aero engines, and actively introducing and absorbing international advanced experience and technology to narrow the gap with developed countries and make breakthroughs in independent innovation.
Difficulties in independent research and development
Aero engines are high-tech products that require the application of knowledge and technology from many disciplines, including materials science, mechanical engineering, thermodynamics, control engineering, and more. Independent research and development of aero engines requires strong R&D strength and technical foundation to cope with technical challenges and difficulties. These technical difficulties are often related to years or even decades of research conducted by foreign manufacturers, and require a lot of investment in capital and manpower and material resources to overcome.
Independent development of aero engines requires the accumulation of a lot of experience and technology, before that, China lacked the corresponding research and development experience and accumulation, and needed to accumulate relevant technology and experience from scratch, which required long-term persistence and patience, and needed to face a lot of trial and error and failure.
It also requires a lot of funding and talent support, which is a high-investment, high-risk process. In the process of R&D, various technical problems will be encountered, and it is necessary to continuously adjust the R&D plan and direction, increase R&D investment, and attract more talents to join the R&D team.
The independent development of aero engines should compete with aero engine manufacturers from all over the world, which have huge technical strength and mature product lines, and they have significant advantages in technology research and development, manufacturing, and sales services. China needs to continuously improve the technical level and market competitiveness of aero engines in order to gain a foothold in the international market.
This is a difficult, high-risk task that requires a lot of effort and investment. However, if China can overcome technological difficulties and make breakthroughs, it will be of great significance for China to establish its brand image in the international market and enhance its independent innovation capabilities.
Turboshaft engines provide more powerful thrust by utilizing the principle of turbocharging and improve the maneuverability and combat capabilities of the aircraft. The advantages of turboshaft engines include a high thrust-to-weight ratio, high fuel efficiency, and lower noise levels.
It consists of a compressor, a combustion chamber, and a turbine. The compressor compresses the air and feeds it into the combustion chamber to mix it with the fuel for combustion. The high-temperature gas produced by combustion passes through the turbine blades, which rotates the turbine and drives the compressor to provide more compressed air. At the same time, the turbine shaft can also be connected to the propulsion device on the aircraft, such as a turbofan or propeller, to create thrust.
By providing more powerful thrust, turboshaft engines can improve the aircraft's acceleration performance, climb speed, and maximum speed. This is especially important for military aircraft, as it can improve their maneuverability and combat capabilities, such as rapid climbing, supersonic flight, and performing a variety of special missions.
The use of advanced combustion technology can effectively improve the combustion efficiency of fuel, reduce exhaust emissions and reduce fuel consumption. For example, more advanced combustion chamber design, fuel injection technology, and combustion control systems are used to improve combustion efficiency and fuel utilization.
