摘要
目标自身热辐射主要的影响因素是目标的表面温度和发射率。针对某型地面作业的移动式空冷柴油发电机的红外隐身效果进行研究,考虑了地面的辐射作用。结果表明保温箱体外壁面和对地热流通道设计有效的降低了箱体外表面的温度以及红外辐射强度,而且模型的整体辐射强度远远小于地面的辐射强度。
The major factors influencing the target thermal radiation are the surface temperature and the radiation rate. The research is about infrared stealth effect of the combination model of mobile air-cooled diesel engine and generator by calculating the radiation effect of ground. Results indicate that the designed model with insulation shell and heat channel toward the ground is an effective way to reduce the shell surface temperature and the infrared radiation intensity. The radiation intensity of whole model is far less than the radiation intensity of ground.
