Apollo / Skylab A7l

A7L Apollo and Skylab spacesuit is the primary pressure suit worn by NASA astronauts for Project Apollo, the three manned flights Skylab and Apollo-Soyuz Test Project between 1968 and the Apollo program ended in 1975. The "A7L" designation is used by NASA as the seventh costume Apollo space designed and built by ILC Dover, a pressure suit manufacturer located south of Dover, Delaware. The A7L is an evolution of design and Coalition A5L A6L. The A5L was the initial design. The A6L introduced the integrated thermal cover micrometeroid layer. After the Apollo 1 fire, the application was updated to be tested fire and received the designation A7L. Eternity Bracelet The basic design was a demand A7L one piece, five-layer "torso limb" suit with synthetic rubber complicated joints in the shoulders, elbows, wrists, hips, ankles and knee joints, "link-net" meshing to keep the costume of balloons in the joints, and a shoulder "block" assembly to allow cable the shoulder to open and close of its bearer. Metal rings on the neck and forearms allowed for the connection of gloves, pressure and the famous Apollo "fishbowl helmet" (Adopted by NASA as it allows an unrestricted view, as well as eliminating the need for a visor seal required in the Mercury, Gemini and Apollo "Block I "spacesuit helmets). A" topcoat, "which was designed to be fire resistant after the Apollo 1 launchpad fire, was joined the pressure garment assembly and was removable for repair and inspection. All costumes A7L appears a vertical zipper that went from the shoulder assembly of demand to the crotch of entry and exit. Between 7 and 14 Apollo astronauts lunar module two, Commander (CDR) and Lunar Module Pilot (LMP), had Costume tips Torso Assemblies (TSLA) with six support life connections placed in two parallel columns on the chest. The 4 lower connectors passed oxygen, a headset Headset / electric connector Biomed was in the top right, and a bidirectional cooling water connector was in the top left. Covers ends of the torso of the Assembly was a costume garment-integrated thermal Micrometeroid (ITMG). The garment protected the suit from abrasion and protected the astronaut radiation solar thermal and micrometeorites that could puncture the suit. The garment was made of thirteen layers of material were (from inside to outside): rubber coated nylon, 5 layers of aluminized Mylar, 4 layers of woven Dacron, 2 layers of aluminized Kapton film / Beta Marquisette laminate, and Teflon-coated cloth filament Beta. In addition, the ITMG also used a patch of "Chromel-R" steel fabric (the familiar silver-colored patch seen especially in the costumes worn by the crew Apollo 11) for protection against abrasion of the life of the laptop support system (PLSS) backpack. Chromel-R was also used in the top of the boots lunar EVA gloves. Finally, patches of Teflon is used for additional abrasion protection on the knees waist and shoulders of ITMG. From Apollo 13, a band of red cloth Beta ITMG joined the commander in each arm and leg and a red stripe on the EVA visor assembly to easily identify the commander lunar module pilot on the lunar surface. Lunar teams also wore a three-layer liquid cooling and ventilation garment (LCG) or "union suit" plastic tube with circulating water to cool the astronaut down, minimizing sweating and fogging of the hull itself. The water was supplied to the LCG of the backpack PLSS. The Command Module Pilot (CMP) had one similar to the TSLA commander and lunar module pilot, but with unnecessary hardware deleted since the CMP would not be carrying any extravehicular activity. For example, the CPD TSLA only one set of gas connectors instead of two, and had no water cooling connector. Also removes the pressure relief valve in the sleeve of the suit and strap mounting hardware that were used in the lunar module. The TSLA for the CMP also deleted an arm bearing that allows the arm to rotate above the elbow. Command module pilots only wore a three-vehicle layer Cover Layer (IVCL) of nomex and beta cloth for fire and abrasion protection. The CMP wore a simple cotton fabric union called the Constant Wear clothing (GTC) underneath the TSLA instead of cooling water liquid cooling garment. His cooling came directly from the flow of oxygen in the suit. When not making Eva Moon, LMP and CDR also had a GTC instead of the LCG. During the last three Apollo lunar flights Apollos 15, 16 and 17, the CDR and LMP started wearing a new moonwalking suit designed for missions long-term J-series, in which three EVAs would be conducted and the lunar rover (LRV) to be used for the first time. Originally developed by ILC-Dover as the A9l "," but given the name "A7LB" by NASA [3], the new suit incorporated two new joints in the neck and waist. The waist joint was added to allow the astronaut to sit on the tram and the neck joint was to provide additional visibility during the driving the tram. Due to the articulation of the waist, the six life-support connectors are rearragned of the parallel pattern to a set of two triangles, and rack up and down he went to the front left of the demand is on the back, and ends on the right shoulder. In addition, the EVA backpacks were modified to carry more oxygen, lithium hydroxide (LiOH), more power and cooling water for the longer EVAs. Because the J-series CSMs incorporated Science Instrument Module (SIM) Bay, using special cameras film similar to those used in spy satellites the Air Force, and requires a "deep space" EVA for retrieval, the CMP for each of the three missions of the J series had a five A7LB based connector series suits A7L H with the liquid cooling connections eliminated as the CMP would be attached to an umbilical life support (like that used on Gemini EVAs) and only one "system purge oxygen (OPS) is used, along with an apple "red" security line for the emergency reserve in case of failure of the cord. The CMP commander had red stripes EVA visor assembly, while the LMP, which conducted a "stand-up EVA" (to avoid the umbilical cord to get "messed up "and to keep the movie in the CSM) in the spacecraft hatch and connected to their normal life-support connections, wore the plain white EVA visor assembly. For the three manned Skylab missions, the three astronauts wore a suit A7LB slightly modified for launch, docking, undocking, and EVA. The dress had a simple Integrated thermal and less expensive clothing and Micrometeroid (ITMG), and an assembly simpler and less expensive extravehicular visor. With the exception of the Orbital Workshop (OWS) repairs conducted by Skylab 2 and Skylab 3, all of the Skylab EVAs were conducted in conjunction with routine maintenance performed at the Apollo Telescope Mount, which housed the the station's solar telescopes. Due to the short duration of EVAs, and as a need to protect the delicate instruments, the lunar EVA backpack was replaced Apollo with a Gemini-style umbilical assembly, except as modified to incorporate both breathing air (Skylab atmosphere was 80% oxygen and 20% nitrogen to 5 psi) and liquid water to cool. The assembly was worn on the waist of the astronaut and serves as an interface between the cord and adapt to. A package of oxygen emergency was tied to the user's right thigh and is capable of providing a supply of emergency 30 minutes of pure oxygen in the case of umbilical failure. A visor assembly EVA similar to that used today in the Shuttle / ISS Extravehicular Mobility Unit worn over the pressure helmet, but Apollo EVA gloves were used. For the Apollo-Soyuz Test Project, NASA decided to use A7LB CMP pressure suit assembly used in the J-missions with a few changes to save cost and weight since an EVA was not foreseen during the mission. The changes include a simplified coating layer was cheaper, lighter and more durable, and the elimination of the pressure relief valve and unused gas connectors. No EVA visor assemblies or EVA gloves were carried out the mission. [5] Of note, the ASTP A7LB suit was the only Apollo suit to use the "worm" logo, a logo that became familiar with all the pressure from NASA, space and flight suits and all Space Shuttle orbiters between 1981 and 2000.
