Large obstacles are "stealth"!New type of ultra -thin wave suction material completes flight test verification

From June 22nd to June 27th, the Civil Aviation Authority of the Second Research Institute of the China Civil Aviation Administration (hereinafter referred to as the "Civil Aviation Second Air Management Office") undertaken the "Light and Lightly Wave Materials to slow down the large -scale construction of the airport in the airport "Items affecting technology research and verification on the signal signal" have completed large -scale metal obstacles construction, new ultra -thin -absorbing materials installation at Dazhou River City Airport, Sichuan, and carried out on -site flight tests to verify the absorbing materials on the navigation beacon multi -diameter. Interference the absorption of electromagnetic waves. The test results show that the absorption rate of the absorption of electromagnetic waves designed and developed by the Civil Aviation Second Civil Pipelines reached 99%, which can achieve the "stealth" of large obstacles. This is the design and construction of large buildings in the airport and surrounding buildings. A new solution is provided.

In recent years, the situation of multi -diameter interference with tall buildings such as the institution, the limited and downgrade of the aviation navigation table has become more and more frequent. The contradiction between environmental protection is becoming more and more prominent. The reporter learned from the Civil Aviation Second Air Management Office that the Civil Aviation Second Air Pipeline has developed and developed a new type of ultra -thin wave absorption material, with a view to solving the problem of multi -diameter interference to navigation signals through electromagnetic absorbing technology.

It is understood that this study is the first research on the field of low -frequency miniaturized and light and thin applications in the field of civil aviation in the field of civil aviation. It is intended to fill the gap in the field. Cross -domain technological innovation is also the first time to carry out a large -scale obstacle to fly test signal in the electromagnetic environmental protection zone of the airport to improve the safety of the operational security of communication navigation surveillance.

The study of this subject is to solve the impact of the airport and surrounding large buildings on navigation signals. For the airport, the safety implementation of the airport II/III operation can be ensured. For large -scale builders, it can be designed according to the original design. The plan is implemented. It only needs to be designed and installed and optimized for the material of the external facade. It is a win -win application technology innovation. According to the relevant experts of the Civil Aviation Second Air Management Office, the new type of light and light absorbing materials is developed this time. First of all, it can solve the pain points of the huge and difficult to install traditional electromagnetic stealth materials. Problem; second, the characteristics of the use of suction materials are easy to design and optimize, and the absorption performance under different absorbing materials can be studied, which can provide optional solutions for the selection of ripple materials during subsequent application applications. Third, the successful test of the multi -diameter interference of navigation signals in the absorbing material is successful, which means that the wave absorption material is suitable for improving the multi -diameter interference of all communication navigation surveillance equipment for civil aviation, and provides a comprehensive aspect of the civil aviation electromagnetic environment safety and local economic construction. solution.
