Abstract : A simplified two-gas system for the Gemini B is defined which provides a mixed gas atmosphere in the cabin and requires no diluent gas make up on board the spacecraft. The system approach is aimed primarily at the elimination of the hazard during ground operations when oxygen pressures are in the 15 to 20 psi range with the present system. Because of the short duration of the crew occupancy after lift-off and prior to crew transfer to the Laboratory, the system provides a mixed gas atmosphere as long as cabin repressurization is not required. Supporting technical analyses are presented including bio-medical considerations, gas flow rates, atmosphere changes during flight, monitoring requirements, and reliability evaluation. Additional testing required is identified. (Author)
