US Anti -Prasket System Come End: In China, made rockets completely invisible

Thus, infrared sensors detect thermal radiation produced by objects, and microwave radars emit and take reflected microwave signals to determine the location of the targets. As the technology develops, stealth materials are also being improved, and many of them are now designed for multi-spectral shrill, which covers everything from visible light to microwave.

However, rockets and planes often work in high temperatures that occur due to external heat sources, such as aerodynamic heating, or internal, such as exhaust nozzles, which cause intensive thermal radiation throughout the infrared spectrum. Moreover, increased temperatures can impair the characteristics of ordinary materials or even cause destruction of the structure.

As a result, there is an urgent need for materials that not only provide multi -spectral secrecy, but also allow you to effectively regulate the temperature. Scientists from the University of Zheczian have developed a highly efficient stealth material that ensures the secrecy in short-wave infrared (SWIR), medium-wave infrared (MWIR), long-wave infrared (LWIR) and microwave ranges-even in temperatures up to 700.

To demonstrate the characteristics of material secrecy, researchers have compared it with a standard "black body" (black heat is a term used for the name of something that absorbs electromagnetic radiation-ed. ). When heated to 700 degrees Celsius, the material showed the radiation temperature of about 422-268 degrees lower than that of the "black body". In terms of radiation intensity, it was 63. 6 and 37. 2% lower than that of "black body" in MWIR and SWIR ranges, respectively.

The key innovation is the composite structure of the material that combines multilayered films and microwave metal. Its top layer serves as a protective barrier against moisture, and the lower layer helps it stick to the underlying surface. This multilayered film also has precision laser engraving, which allows you to transmit microwave without harming infrared characteristics.

US President Donald Trump has announced that the government will build a Golden Dom (Golden Dome) missile defense system, an American analogue of the Israeli Iron Dome - in the next few years. The proposed system is aimed at counteracting ballistic missiles, hypersonic weapons and winged rockets and will include space tracking sensors. The L3harris defense enterprise plays a key role in this project.

In an interview with The Washington Times, Ed Zyss, a president of space and onboard systems in L3harris, said that the satellite group of the company was using infrared technology to track spaces from space. "[Satellite] sees thermal signatures throughout the Earth," Zoys explained. "And the purpose of this satellite is to detect a dull thermal signature of hypersonic weapons and track it. Over the past 13 months, we have proven that it can be done from space.

" He added that L3harris satellites provide critical tracking data for missile interceptors aimed at destroying hypersonic threats. If infrared tracking is the main method for the Golden Dome system for the detection and interception of hypersonic weapons, materials that offer combined infrared and microwave secrecy can significantly reduce the likelihood of detection. In conditions similar to a speed of more than 2 times the speed of sound, its surface remained 72.

4 degrees Celsius colder than standard materials such as molybdenum. This helps maintain the equipment more stable and less prone to overheating during aerodynamic heating. "The process of making this device covers simple methods, such as deposition and laser digestion," Chinese scientists said. "This makes it scaled and easy to introduce in large -sized applications. " Earlier, we wrote that Trump's "Golden Dome" received the first component.
