With the continuous development and growth of China's aerospace technology, the domestic fifth-generation fighter J-20 has achieved remarkable results and entered the stage of mass production. As a fighter with a high degree of integration and advanced design concepts, the J-20 not only demonstrates the strength of the mainland in the field of aviation, but also allows the world to see China's breakthroughs and achievements in high-tech manufacturing.
However, there is a question that has been attracting much attention -- whether the canard wing located on the outside of the left wing of the J-20 will affect the stealth performance of the fighter? After conducting in-depth research on this issue, we found that thanks to China's continuous improvement of the high processing technology level and the application of advanced stealth materials and design methods, the canard wing has little or even no impact on the overall stealth effect of the J-20! We will explain this conclusion from several aspects:
1. High-precision processing technology ensures stealth
To minimize the radar reflection area (RCS), modern stealth aircraft often employ a variety of cutting-edge technologies and materials to reduce surface roughness, gaps, and other factors that can lead to scattering sources. In the process of continuous development of China's aviation industry, it has accumulated rich experience and technical reserves, especially in the field of high-precision machining. These technologies have been widely used in the process of making the J-20, ensuring that the edges of the engine air intake, the joints of the fuselage structure and other joints with the canard wing can achieve a very high degree of smoothness, thereby effectively avoiding the radar wave scattering phenomenon caused by rough surfaces, further enhancing the low visibility characteristics of the whole aircraft, and showing the level of China's aviation technology and independent innovation spirit well;
2. The unique design of the canard wing enhances stealth performance
In addition to the application of high-precision manufacturing processes, through the unremitting efforts of scientific researchers, special shapes and layouts for the canard wings have been successfully designed to suit the overall stealth needs. The optimization and adjustment of this design minimizes the radar wave scattering generated by the canard, which will not affect the stealth characteristics of the main engine, and at the same time can give full play to the excellent maneuverability and handling performance brought by the canard, so as to achieve a win-win situation of functionality and stealth.
3. New stealth materials and coatings to further improve stealth performance
In addition, the use of new materials is also one of the effective means to improve the stealth ability of the aircraft, such as absorbing coatings and stealth composite materials, which are also widely used on the J-20. By applying these high-performance materials to the surface of the aircraft and the parts related to the canard, the penetration and reflectivity of the radar wave can be greatly weakened, so that the whole fuselage can present a better stealth state, which further confirms that the impact of the canard wing on the stealth of the host is controllable and limited.
To sum up, we have reason to believe that with the continuous upgrading of China's manufacturing industry, especially the continuous improvement of the level of high processing technology, the J-20 fighter will continue to maintain excellent stealth performance in the future, and will not be interfered with by the design of the canard, on the contrary, the existence of canards will bring it more tactical advantages, such as stronger air combat flexibility and more stable flight control quality, etc., will be significantly improved, so as to achieve a leapfrog development of China's combat power construction and demonstrate to the international community China's determination and ability to defend national security
