Lessons Learned - Start Transient Leak Detection System (STLDS)
Year: 2010
Abstract: Abstract:
Cryogenic propulsion systems use extremely cold propellants and high pressures to achieve the thrust-to-weight ratios required for space vehicles. Leakage from these systems during operation can cause changes in pressure within an enclosed fuselage (such as the Space Shuttle vehicle [SSV]) that are significant enough to be recognized as the initiation of a potentially catastrophic leak. Monitoring for these unexpected changes in pressure can allow detection of a leak in time to abort a launch and possibly prevent damage to or loss of the vehicle.
