According to the old saying, being late leaves you open for attack. Different countries’ military industries are continually exploring new areas of technology and science thanks to their scientific progress. Recent years have seen stealth technology become an increasingly popular topic with military scientists as well as scientists. Let’s find out what stealth tech is.
Stealth technology refers to the Low Observable Technology. The goal is to modify the detectability information characteristics our target using various technical methods.
Stealth technology extends traditional camouflage technology. Because of its appearance, camouflage technology can be made offensive or defensive, passive, active, and thus enhances troops’ ability to survive, as well increasing enemy threat.
Stealth is a complex concept. It requires stealth materials to be developed. Stealth material can improve survival rates, reduce detection rates and lower the detection rate. This is the basis for weapon stealth. It’s also an essential part of stealth tech. You can divide stealth materials into visible, sound, infrared and visible light. It is possible to divide it into stealthy structuring material and stealthy coating material depending on the materials forming and carrying capacities. Therefore, stealth materials are of vital military importance. This technology will play an integral part in national defense high tech. It can be used on aircraft, main battle tank, ships, and arrows. The goal of ground weapons is to stop aerial radar detection or infrared device detection, radar-guided weapons attack and radar-guided bombs attacks; combat aircraft are to avoid detection by awACS radar and airborne firecontrol radar as well as infrared and active radar, infrared fighter missiles and air-to-air radar.
Nanomaterials are The Next Generation of Stealth Materials
Because of their wave-absorbing abilities, nanomaterials are being used by scientists as stealth materials. They are excellent experiment materials because of their surface, quantum, and small size effects.
Based on their absorbing mechanisms, stealth material can be divided into magnetic loss type and electric loss types. We will be taking as an illustration the absorbent mechanism of nanometer-sized electroloss-type stealth material.
A decrease in metal powder’s particle size (e.g. iron, nickel) will result. Conductivity decreases at the nanometer-level, and specific saturation magnetization drops. But, magnetization and coerciousness rise sharply, especially once the level reaches the nanometer. The activity of nanomaterials increases as more atoms appear on the surface during thinning. In order to increase the material’s wave absorbency, electrons or atoms can move faster under certain frequencies of electromagnetic radiation.
The Prospect of Stealth Materials
The current engineering research remains incomplete and has not yet been published due to confidentiality. But nano stealth technologies have emerged as a major research direction in stealth materials and their application will have huge implications for the military, political and economic aspects of every country.
