The pressure suits were called A7LB, which came in two versions. The Extra-vehicular (EV) version was a new mid-entry suit that allowed greater mobility and easier operations with the lunar rover. The A7LB EV suits were designed for longer duration J-series missions, in which three EVAs would be conducted and the Lunar Roving Vehicle (LRV ...

The Apollo model A7LB was the ultimate moonwalking suit. This Extravehicular Mobility Unit (EMU) allowed a crewman to work on the moon for up to seven hours. The suit’s red stripes identified the mission commander.

In this paper, an ABAQUS/Explicit FEA model was developed to predict elbow joint torques during pressurized convolute sleeve bends using the Apollo A7LB pressure garment assembly (PGA) arm configuration. Design data was extracted from available literature and images.

Each Apollo astronaut had three custom fitted A7L suits - one for flight, one for training, and one for flight back-up. The Apollo suit weighed 22 kg and its PLSS Portable Life Support System, 26 kg. The A7LB modification was used for Apollo J series lunar landing missions. The A7LB with an additional thermal garment was used for Skylab.

The suit was constructed by the International Latex Corporation, with the designation A-7LB, and consisted of approximately 26 layers of materials designed to protect the astronaut from the extremes of temperature to be found in the vacuum of space and on the lunar surface.

1971年11月5日 · The second configuration is designated as the EV A7LB PGA which provides low-pressure and fire protection in the IV mode and protection from the lunar surface environment during EVA. The EV A7LB PGA also provides free-space environment protection during open-hatch operations associated with com-mand module (CM) EVA.

The lunar overboot was updated to match the new A7LB suit for Apollo 15 through 17. While the boot was visually identical, the interior layers were changed to include Teflon-coated Beta cloth (fire resistant shell), two layers of Beta marquisette Kapton laminate (outer insulation), nine layers of aluminized Mylar (insulation film) alternating ...

Each Apollo astronaut had three custom fitted A7L suits - one for flight, one for training, and one for flight back-up. The Apollo suit massed 49 lbm (22 kg) and its PLSS, 57lbm (26 kg)*. The A7LB modification was used for Apollo J series lunar landing missions. The A7LB with an additional thermal garment was used for Skylab.

The space suit used for Apollo project was called A7L / A7LB. The head character 'A' means Apollo project. Second character '7' means model number. Third 'L' means manufacturer. In Apollo project, from earlier A1C to last A7LB, 15 types of space suits were developed.
