The Extravehicular Mobility Unit (EMU) is an independent spacesuit that provides environmental protection, mobility, life support, and communications for astronauts performing extravehicular activity (EVA) in Earth orbit.

This new PLSS, referred to in conjunction with the Space Suit Assembly (SSA) as the Advanced EMU (AEMU), will need to be capable of functioning when: attached to differing configurations of SSA, operating with an airlock style vehicle, operating with a …

This paper performs a comparison between the Shuttle/ISS EMU PLSS schematic and the Advanced EMU PLSS schematic complete with a discussion for each difference.

As NASA changed from launching astronauts on expendable rockets to the Space Shuttle system with its reusable orbiter and solid rocket boosters, spacesuit engineers began deve l o pment of a reusable EMU. Previously, all spacesuits were one-time garments. Spacesuits were custom-built to each astronaut’s body size.

2012年1月1日 · This paper performs a comparison between the Shuttle/ISS EMU PLSS schematic and the Advanced EMU PLSS schematic complete with a discussion for each difference. In order to be able to adapt to differing vehicle interfaces such as suitport and airlock, adjust to varying vehicle pressure schedules, tolerate lower quality...

2009年8月1日 · The RCU was a component of the total Extravehicular Mobility Unit (EMU) space suit system, which also included the Portable Life Support System (PLSS), Oxygen Purge System (OPS), and the suit itself. The system was added to the EMU after the redesign following the Apollo 1 accident.

THE EMU SYSTEM DESCRIPTION (Including Support Accessories) GENERAL DESCRIPTION The extravehicular mobility unit (fig. I-1) is designed to protect the crewman in a low pressure environment and provide comfort, mobility, dexterity, and a specified unobstructed range of vision during pressurized and unpressurized modes of operation.

The “backpack” of the Apollo spacesuit was named the Portable Life Support System (PLSS). The PLSS supplied pressure and oxygen, removed carbon-dioxide, particulates and odors, provided cooling, and controlled humidity within safe and comfortable parameters. Apollo flight PLSSs were

Viewgraphs on extravehicular mobility unit (EMU) portable life support system (PLSS) technology recommendations are presented. Topics covered include: oxygen supply storage; oxygen supply regulators; carbon dioxide control; prime movers; crew comfort; heat rejection; power sources; controls; display devices; and sensor technology.
