Recently, ISRO has successfully accomplished 3 major qualification tests for the Crew Module (CM) systems of the Gaganyaan mission.
Float Inflation Test – Crew Module Up‑righting System (CMUS)
- Purpose – Ensures the Crew Module remains upright after splashdown in the sea.
- System – Stored cold gas‑based up‑righting mechanism.
- Outcome – Demonstrated successful inflation of primary flotation devices, meeting functional, performance, and inflation time requirements across operating pressure ranges.
Umbilical Separation Test – Crew Module Service Module Connect and Disconnect System (CSCDS)
- Role – Provides electrical and hydro‑pneumatic umbilical link between Crew Module (CM) and Service Module (SM).
- Functions – Enables communication and fluid transfer for Environment Control and Life Support System (ECLSS).
- Outcome – Validated clean separation of CSU‑2 (Crew Module side), structural stability of CM panel, and design margins for re‑entry safety.
Structural Qualification Test – Apex Cover Separation Loads
- Role – Apex cover protects parachutes and subsystems during mission.
- Process – Separated at predetermined altitude using pyrotechnically actuated thrusters before parachute deployment.
- Outcome – Test rig applied 1.75× estimated loads; confirmed strain, deformation, and design margins, validating CM structural integrity during separation.
