Description

Technical Field

[0001] This invention relates to the field of water mist infrared stealth technology, specifically to a fine water mist infrared stealth solution and its preparation method. Background Technology

[0002] Artificial water mist can interfere with infrared imaging-guided weapons, protecting critical equipment by forming a fine water mist to shield against thermal radiation. Spraying water mist onto object surfaces is an effective way to reduce infrared radiation intensity. The absorption, scattering, and water film coverage of fine water mist particles effectively attenuate infrared radiation. This paper introduces the principles of fine water mist infrared stealth technology, discusses the classification and generation principles of fine water mist from domestic and international research, and identifies several common atomizing nozzles. Based on this, it qualitatively analyzes the impact of droplet size, droplet concentration, water mist thickness, water film thickness, and water flow velocity on stealth effectiveness. In practical applications, besides optimizing the design of atomizing nozzles, water supply pressure, and water flow rate, further optimization of the water mist solution is possible. To increase the suspension time of fine water mist particles and prevent solution sedimentation and algae growth, different types of additives need to be added to prepare the aqueous solution, further reducing infrared radiation intensity and achieving stealth effects. Experimental studies show that the preparation method and ratio of the atomized aqueous solution have a significant impact on the infrared shielding of object surfaces, and users' self-prepared solutions are unlikely to achieve ideal atomization shielding effects.
