研究了湍流加热对先进翼面进入飞行器热防护系统(TPS)质量的影响。考虑了四个基本系统：绝缘系统、金属热结构系统、金属隔热系统和混合系统。使用专为考虑中的每个TPS概念的特征量身定做的进入轨迹来进行TPS的大小调整。比较了以前所有层流加热假设下的系统大小和使用过渡和湍流加热的基线估计大小的系统。还考察了不同过渡标准对TPS质量要求的相对影响。还研究了为缓解湍流加热而量身定做的进入轨迹。结果表明了湍流加热对TPS质量的显著影响，并证明了准确的过渡准则和进入轨迹调整的重要性。
This study examines the impact of turbulent heating on thermal protection system (TPS) mass for advanced winged entry vehicles. Four basic systems are considered: insulative, metallic hot structures, metallic standoff, and hybrid systems. TPS sizings are performed using entry trajectories tailored specifically to the characteristics of each TPS concept under consideration. Comparisons are made between systems previously sized under the assumption of all laminar heating and those sized using a baseline estimate of transition and turbulent heating. The relative effect of different transition criteria on TPS mass requirements is also examined. Also investigated are entry trajectories tailored to alleviate turbulent heating. Results indicate the significant impact of turbulent heating on TPS mass and demonstrate the importance of both accurate transition criteria and entry trajectory tailoring.
