摘要

在行星进入和地球返回探测任务中，高焓高速气体导致飞行器表面承受显著的热辐射效应。辐射效应传输机制与能量热传导模式不同，体积辐射效应的影响依赖于热防护材料的辐射特性。本文在传统烧蚀模型中引入体积辐射传输方程，建立轻质针刺石英纤维/酚醛树脂复合材料体积辐射-烧蚀热响应模型。通过与试验结果对比分析表明，体积辐射-烧蚀模型比传统模型具有更高的预测精度；高辐射加热会加速复合材料内部的酚醛树脂热解，同时产生更高的内部热解气体压力，而高对流加热则会提高复合材料表面的烧蚀后退速率。本文工作可为轻质针刺石英纤维/酚醛树脂复合材料在深空探测飞行器热防护系统中的工程化应用提供一定的指导。

Abstract

During planetary entry and Earth return missions

spacecraft surfaces experience significant thermal radiation effects due to high-enthalpy and high-velocity gases. Unlike conductive heat transfer

the volume radiation effect depends critically on the radiative properties of thermal protection materials. The lightweight needled quartz fiber/phenolic resin composite demonstrates favorable characteristics for radiative heat transfer due to its high porosity and semitransparent medium properties. This study developed an improved thermal response model by incorporating volume radiative transfer equations into conventional ablation models. Comparative analyses with experimental data demonstrated that the proposed volume-radiation-ablation model achieved superior prediction accuracy compared to traditional approaches. The results revealed that composites with higher absorption and scattering coefficients exhibited enhanced thermal insulation performance. Under high-radiation heating conditions

accelerated pyrolysis of phenolic resin occurred within the material

accompanied by increased internal pyrolysis gas pressure. Conversely

high convective heating conditions primarily increased the surface ablation recession rate. These findings provide valuable insights for engineering applications of lightweight needled quartz fiber/phenolic resin composites in thermal protection systems for deep space exploration vehicles.
