【摘要】 介绍了利用InSb红外辐射计在弹道靶上测量底部直径为10mm、半锥角和头部半径分别为9°、2.2mm(模型A),8°、0.6mm(模型B)的两种非烧蚀钝锥模型及其尾迹的红外辐射。模型速度大于6km/s,飞行环境压力约4.8kPa,红外辐射测量波段为1~3μm、3~5μm。结果表明:非烧蚀钝锥模型头身部红外辐射远大于尾迹红外辐射,在相同飞行速度和环境压力条件下,模型A产生的红外辐射比模型B产生的红外辐射强。更多还原

【Abstract】 The experiment of measuring infrared radiation of non-ablation blunt cone and wake using InSb infrared radiometers on ballistic range is described in this paper.The IR radiation distributions in 1～3μm and 3～5μm bands for model A with 10mm base diameter,9° half-cone angle,2.2mm head radius and model B with 10mm base diameter,8° half-cone angle,0.6mm head radius are obtained.The model velocity is over 6km/s,and environment pressure is about 4.8kPa.The results show that the IR radiation of model is stronger than the IR radiation of wake,and the IR radiation of model A is stronger than model B at the same test conditions.更多还原
