| Abstract: |
| Based on illustration of helicopter infrared radiation characteristics and threats, the suppression principle of helicopter infrared radiation characteristics was discussed. Research progress of helicopter infrared radiation suppression technology was reviewed, and characteristics and application scope of various infrared radiation suppression technologies were analyzed in detail. Helicopter infrared radiation characteristic suppression technologies mainly included infrared suppressor technology, IR decoy flare, thermal infrared stealth coating technology, camouflage stealth technology. The infrared suppressor suppression technology utilized mixed flow device to reduce temperature of hot air and heat insulated isolation device to isolate high temperature parts. The IR decoy flare interfered with infrared reconnaissance and attacked infrared guided weapons by using numerous infrared characteristic signals released when pyrotechnic compound burned and produced high temperature. Thermal infrared stealth coating technology reduced the infrared radiation characteristics of helicopter surface based on its low infrared emissivity, hence it can be integrated with air-land context well. The camouflage stealth technology realized multi-band stealth as well as windproof, rainproof and dustproof properties by utilizing camouflage equipment featuring in optic, infrared and radar stealth properties. Finally, future research of infrared stealth technology was expected. |
