Airlock Environmental and Temperature Control Systems 690623
The principal objective of the Apollo Applications Program (AAP) is to keep astronauts in space for extended periods of time. This paper reviews the Environmental and Temperature Control Systems needed to support the men in space for periods up to eight months. The ECS must pressurize the various stages with mixed gas atmosphere, control oxygen pressure, remove carbon dioxide, and provide cooling for astronauts wearing liquid cooled garments.
The TCS features a bifillar radiator for flow stability, electrical wall heaters for warmth, and thermal curtains to minimize heat loss.
The functions performed by ECS and TCS, and the operating systems which perform these functions, are described in depth.
