中文摘要:
针对飞机红外隐身和反隐身技术发展的需要,建立了隐身飞机红外图像的仿真模型,并对飞机的红外隐身效果进行了评估.首先在飞机红外辐射计算模型的基础上,对二元喷管、低发射率蒙皮、发动机舱隔热、喷管冷气注入等进行红外隐身建模,经过渲染生成隐身飞机的红外图像;然后对低发射率蒙皮、发动机舱隔热与喷管冷气注入3种红外隐身措施的隐身效果进行分析.仿真结果表明,不同的隐身措施下,隐身战斗机辐射差异较大.
English Summary:
Aiming at the urgent need of the development of infrared stealth technology and anti-stealth technology, a simulation model of infrared image of stealth aircraft was established, and the effect of infrared stealth of stealth aircraft was quantitatively evaluated. Firstly, the infrared stealth modeling was accomplished for the two-dimensional exhaust, low emissivity skin, engine room insulation and cold air injection based on the infrared radiation calculation model of the aircraft, and the infrared image of the stealth aircraft was generated through rendering. Then the stealth effect of three infrared stealth measures including low emissivity skin, engine room insulation and cold air injection were analyzed. The simulation results show that the stealth fighter radiation varies greatly under different stealth measures.
