| The pressurized barrel shaped cabin was 25.1968 inches (640mm) in diameter and the length was 31.496 inches (800mm). The cabin had a removable cover with a viewing hatch. Cabin pressure was maintained at 765mm (note- normal atmospheric pressure on earth is 760mm or 14.7 pounds per square inch). A bellows-actuated pressure switch switched off the oxygen (O2) generator if pressure exceeded 765mm. The life-support system was designed for 7 days of flight. (2) |
