摘要
通过采用工程计算方法求解高超声速飞行器碳-碳复合材料分别在气动热、激光单独作用以及气动热/激光耦合作用下的热化学烧蚀。计算分析表明: 激光单独作用下, 碳-碳复合材料的烧蚀速率较小;随激光能量的增加, 碳-碳复合材料的烧蚀速率增加;气动加热条件下激光对高超声速飞行器碳-碳复合材料的烧蚀毁伤效应会明显增强;沿弹道的气动加热累积效应对碳-碳复合材料气动热/激光耦合烧蚀作用不明显。
Abstract
The thermo-chemical ablation of the carbon-carbon complex material of hypersonic vehicles in the condition of aero-heating and laser ablation respectively and coupled aero-heating with laser ablation were calculated via the engineering calculation method. The numerical results indicate that: the ablation rate was minor with laser ablation only; the ablation rate rose with the laser energy increase; in the condition of aero-heating, laser ablation damage factor of carbon-carbon material for hypersonic vehicles will increase greatly; the aero-heating cumulating effect was not distinct to the coupling ablation of aero-heating and laser ablation.
