Apollo / Skylab A7l
The Apollo & Skylab spacesuit is A7L the primary pressure suit worn by NASA astronauts for Project Apollo, the three manned Skylab and Apollo-Soyuz Test Project between 1968 and the end of the Apollo program in 1975. The "A7L" designation is used by NASA as the seventh Apollo spacesuit designed and built by ILC Dover, a manufacturer of combinations of pressure located south of Dover, Delaware. The A7L is a design evolution of ILC A5l A6L. The A5l was the original design. The A6L introduced the integrated thermal layer coverage and micrometeroid. After the Apollo 1 fire, the prosecution has been upgraded to the ordeal of fire and given the designation. A7L Eternity Bracelet The basic design of the combination A7L was a part of a five-layer "torso-limb" suit with convoluted joints made of synthetic rubber in the shoulders, elbows, wrists, hips, ankles and joints knee, "link-net mesh to prevent continuation of the ball joints, and a shoulder block" cable "of the Assembly to allow the shoulder to be extended and retracted by its wearer. metal rings at the neck and right forearm for connection of pressure gloves and helmet from the famous Apollo jar "(adopted by NASA as it allowed a view, as well as eliminating the need for visor seal required in the Mercury and Gemini & Apollo "Block I spacesuit helmets). A "coating", which was designed to be resistant to fire after the Apollo 1 fire panel has been attached to the pressure and clothing was removed for repair and inspection. All A7L combinations featuring a vertical zipper that went from the Assembly of shoulders to the crotch of the costume to enter and exit the suit. Between 7 and Apollo 14 lunar module two astronauts, Commander (CDR) and driver Lunar Module (LMP), had Torso Limb Suit Assemblies (TSLA) with six life-support connections placed in two parallel columns on the chest. The 4 lower connectors passed oxygen, a headphone / electrical connector Biomed has been up right, and a bidirectional connector of the cooling water was at the top left. Covering the Torso Limb Suit Assembly was an Integrated Thermal Underwear Micrometeroid (ITMG). The garment protected from the combination of abrasion protection astronaut from solar radiation and micrometeorites heat that could penetrate the suit. The garment was made of thirteen layers of material that have been (from inside to outside): rubber coated nylon, 5 layers aluminized Mylar, 4 layers of nonwoven Dacron, 2 layers of aluminized Kapton film Marquisette Beta / laminate, and Teflon-coated filament Beta fabric. In addition, the ITMG also used a patch of "Chromel-R` s woven steel (the familiar silver patch seen especially on the costumes worn by the Apollo 11 crew) for abrasion protection of the Portable Life Support System (PLSS) backpack. Chromel-R was also used on top boots and gloves lunar EVA. Finally, patches of Teflon were used for protection from abrasion on the size of the knees and shoulders of ITMG. Beginning with Apollo 13, a strip of red cloth Beta was incorporated ITMG commander on each arm and leg, and a red stripe on the EVA visor Assembly to easily distinguish the commander from the lunar module pilot on the lunar surface. Lunar crews also wore a liquid three layers of cooling and ventilation garment (LCG) or "suit union" with plastic tubing which circulated water to cool the astronaut and minimizing sweating and fogging of the helmet as well. The water was supplied to the LCG the PLSS backpack. The command module pilot (CMP) had a similar TSLA the commander and lunar module pilot, but with unnecessary hardware deleted since the CMP would not run for the spacewalk. For example, the CMP TSLA one set of gas connectors instead of two.
