摘要
舱外活动(EVA)系统可分为3部分:1)航天员装备系统,包括舱外航天服(EVA航天服)、安全系绳和机动装置;2)空间支持系统,包括气闸、约束装置、EVA工具、在轨训练设施、遥控自动操作装置,以及表面运输工具;3)地面试验、训练与保障系统,包括减重/失重设施、热/真空试验舱、虚拟现实模拟系统、星体表面模拟场地,以及任务保障设施。文章阐述EVA系统的组成与功能,评述EVA技术现状及发展趋势。
EVA System can be divided into three parts： 1） the EVA astronaut＇s dressing system, including EVA suit, the portable life support system, and safety tethers and/or maneuvering devices; 2） the space support system, including airlock, restraints, tool-kits, teleoperated robotic devices, and transportation vehicles on the moon or other planetary surfaces;3） the ground-based test, training and support system, including reduced-gravity facilities, one-g facilities （such as thermal/vacuum test chambers, virtual reality EVA training）, analog sites, and mission support facilities. In this paper, EVA System architecture and functional capabilities as well as EVA system current state of the art and future requirements are expounded and commented.
