Research Triangle Institute prepared this final report for the Air Force's 30th Space Wing at Vandenberg AFB and 45th Space Wing at Patrick AFB, completed September 10, 1996, under Contract No. FO4703-91-C-0112. The report describes how "Mode-5 failure responses," meaning significant vehicle deviations from the intended flight line, are modeled in RTI's risk-analysis program DAMP, using two shaping constants calibrated by trial and error against simulated malfunctions for vehicles including Atlas IIAS, Delta-GEM, Titan IV, and LLV1.
