Abstract To predict the debris survivability during an atmospheric re-entry and assess the prospective risk on ground, CNES develops an engineering tool named DEBRISK, based on an object-oriented approach. This approach is currently limited to primitive shapes and is therefore difficult to apply to more complex shapes. The objective of this work is to present a new methodology, based on the MISTRAL software, to introduce more complex shapes within DEBRISK with the goal to deal accurately with the atmospheric re-entry of more realistic objects. Moreover, this new methodology is validated by setting up an experimental campaign performed in the Von Karman Institute Longshot wind tunnel.

DEBRISK 大气再入工具中复杂形状的空气热力学建模：方法和验证

摘要 为了预测大气再入过程中碎片的存活性并评估地面的潜在风险，CNES 开发了一种基于面向对象方法的工程工具 DEBRISK。这种方法目前仅限于原始形状，因此难以应用于更复杂的形状。这项工作的目的是提出一种基于 MISTRAL 软件的新方法，在 DEBRISK 中引入更复杂的形状，目标是准确处理更逼真的物体的大气再入。此外，这种新方法通过在冯卡门研究所 Longshot 风洞中进行的实验活动得到验证。
