| description abstract | Description of Driving Event: Quick disconnects, utilized for providing gasses to the space shuttle main engine drying/purge lines and the main propulsion system LH2 prepressurization system are identical and can be crossconnected in the OPF. The MPS heated GN2 purge panel provides heated or unheated GN2 at 645 +/- 65 psig for engine drying. Should GN2 645 +/- 65 psig be introduced to the GH2 prepressurization system, flight hardware damage could occur. This condition may or may not be visible on the firing room pressure gages depending upon the status of orbiter power. | |
