摘　　要：我国探月三期工程重要成果之一是采集月球样品并返回地球,由于我国尚无环月轨道样品转移操作的成功实践,可靠的转移技术是月球样品顺利转移的关键。基于这一目的,提出了一种喷气式月球样品转移装置。介绍了装置组成及工作方式,实现了基于连续射流理论的流场模型建立。根据该模型在ADINA软件进行了初步的气体流场仿真,并进行了地面验证试验。试验结果表明喷气装置能够顺利实现样品转移功能,可为我国月球样品转移提供一定参考。One of pivotal achievements for the third stage program of China’s lunar exploration project is to collect lunar samples and return to the earth. Since there are no successful sample’s transfer operations in China, reliable transfer technology is the key to sample’s transfer. On account of this, a new air-jet device of lunar sample’s transfer is presented. We introduce the composition of device and manner of working particularly, and build a flow field model which is based on continuous air-jet theory, and analyze air flow field and accomplish ground experiments. The results show that the air-jet device can achieve sample’s transfer and make corresponding references for lunar sample’s transfer of China.
