一种太阳翼气动热防护装置
摘要：
本发明公开了一种太阳翼气动热防护装置，属于航天器热控制技术领域。所述气动热防护装置从下往上包括底膜、间隔层、表层面膜、次表层面膜，通过缝制线将其固定；在气动热防护装置上设有销钉孔与太阳翼压紧点预埋件穿出孔。本发明还公开了一种太阳翼气动热防护方法：将气动热防护装置安装在太阳翼的背面，销钉从气动热防护装置上预留的销钉孔穿过后，在销钉的顶部安装压片，以防止气动热防护装置从销钉上脱落。相对于传统的采用裸面太阳翼来说，本发明所采用的气动热防护装置在气动减速过程中，可以在一定程度上隔离气动热，使太阳翼温度保持在可耐受范围内。
摘要（英）：

The invention discloses a solar wing pneumatic thermal protection device, which belongs to the technical field of spacecraft thermal control, and comprises a bottom film, a spacer layer, a surface layer surface film and a secondary surface layer surface film from bottom to top, and is fixed through sewing threads. The solar wing pneumatic thermal protection device is provided with a pin hole and a solar wing compaction point embedded part through hole. The invention further discloses a solar wing pneumatic thermal protection method, wherein the solar wing pneumatic thermal protection device is arranged on the back surface of a solar wing, and the top portion of a pin is provided with a pressing plate after the pin passes through from a pin hole which is obligated on the solar wing pneumatic thermal protection device, thereby preventing the solar wing pneumatic thermal protection device from falling off from the pin. Relative to a traditional mode adopting a naked solar wing, the solar wing pneumatic thermal protection device can space pneumatic heat in a certain degree during the pneumatic deceleration process, thereby leading the temperature of a solar wing to be kept in a tolerable range.
