Scientific paper

An overview of the testing performed to define maximum loads on the EMU as a result of handling massive objects is presented. Test results and the impact on EMU design are reviewed. The effect of suit arm span sizing on maximum loading is examined. It is demonstrated that significant loading of the EMU restraint system can occur as a result of handling massive objects during EVA when the crew member is in fixed foot restraints. These loads are greater than loads resulting from the subject's isometric strength only. It is also shown that satellite loads only occur when the object is at the extreme of the subject's reach envelope. High loads are not imparted to the EMU when the massive object is retained in the crew member's reach envelope.
