摘要
在水下中性浮力状态环境中,利用航天器水下模型进行出舱活动试验和训练是地面最有效的失重模拟手段之一,水下设备研制相比飞行设备有其特殊性。本文介绍了美国和俄罗斯出舱活动相关水下试验与训练设备的发展和现状,通过其主要应用、逼真度分级、应用时机和材料选用等分析,给出了对我国有借鉴意义的研制水下试验与训练设备的启示。
Neutral buoyancy is an essential tool for simulating weightless testing and training with underwater spacecraft mockups. The development of underwater mockup is different from that of flight hardware. This paper briefly introduced the development and current situation of EVA related underwater mockups in US and Russia. On the basis of the analysis of mockup applications,fidelity classification,applicable phases and material selection,suggestions on how to develop underwater mockups in China were proposed in the end.
