Purpose of the Study:

• To rigorously verify the reliability and safety of onboard crew support facilities for manned spacecraft.
• To ensure all systems meet stringent spaceflight requirements.
• To validate the effectiveness of implemented safety and reliability programs.

Main Methods:

• Employed comprehensive qualitative and quantitative projection verification techniques.
• Included analysis, checks, demonstrations, and rigorous testing.
• Conducted thorough reliability assessments and failure analyses.

Main Results:

• Successfully realized all work-items defined in the reliability and safety program.
• Established robust assurance measures for safety-critical components.
• Integrated Failure Modes and Effects Analysis (FMEA), System Hazard Analysis (SHA), and Fault Tree Analysis (FTA).
• Completed comprehensive safety and reliability evaluations at both equipment and system levels.

Conclusions:

• Achieved design specifications for facility safety and reliability.
• Met all stringent requirements for manned spacecraft spaceflight tests.
• Confirmed the suitability and dependability of crew support facilities for space missions.
