武装直升机红外隐身系统研究

根据武装直升机在执行作战任务时所面临的战场环境,明确了红外隐身时重点考虑红外制导导弹的威胁,介绍了红外制导的方式及发展趋势,导出了导弹在点源制导和成像制导两种情况下作用距离的计算公式,论述了获得武装直升机红外辐射特性的理论分析计算和飞行测量两种途径,通过算例研究辐射强度和温差对导弹作用距离的影响,并对红外抑制效果与途径进行分析. 

Research on infrared stealth system for armed helicopter

Based on the battlefield environment for performing operational mission, emphasis should be placed on the threat from infrared guided missile when conducting infrared stealth for armed helicopter. Modes and developing tendency of infrared guidance were introduced, calculation formulas of performance range of point source and imaging guided missile were derived, and two approaches, theoretical analysis computation and flight measurement, of obtaining infrared radiation characteristic of armed helicopter were described. Effects of radiation intensity and difference in temperature on missile performance range were studied through samples. Infrared suppression effects and approaches were analyzed.
