Lessons Learned – ACTS Pyro Separation Band Anomaly (Shuttle Orbiter)

Abstract:

Minor damage to the Shuttle was caused when the firing of the primary explosive cord to deploy the payload from the cargo bay also triggered the backup cord. End-to-end system tests had validated the erroneous design rather than the end function. Document electrical-mechanical interfaces, protect hazardous systems against any possible unintended operation, and consider use of a single cord configuration.
