LengyelSubject: International Space Station (ISS) Program/Extravehicular Activity (EVA)/Extravehicular Mobility Unit (EMU) Planar Hard Upper Torso (HUT)
2、Description of Driving Event: Validation of Extravehicular Mobility Unit (EMU) Planar Hard Upper Torso (HUT) CapabilityLesson(s) Learned: The three available sizes of Extravehicular Mobility Unit (EMU) planar Hard Upper Torso (HUT) units will accommodate crewmembers from the 40th percentile female t
3、o the 95th percentile male. Assumptions were made regarding the ability of crewmembers to upsize or down-size to fit the three available HUT sizes and operate safely and effectively in them.Recommendation(s): To validate the ability of crewmembers to actually use the various available HUT sizes, cre
4、wmembers in each of the several size combinations/configurations should be required to perform normal and emergency functions in training mockups to demonstrate that full capability is available to each.Evidence of Recurrence Control Effectiveness: NASA agrees with the ASAP recommendation, as it is
5、part of our standard process. Crewmembers are sized in 1-G and suit fit is verified during Neutral Buoyancy Laboratory (NBL) and vacuum chamber testing. Nominal suit fit capability is verified in the NBL, while emergency procedures are demonstrated under vacuum conditions using flight hardware.Docum
