Safety and Reliability:
The safety and reliability analysis was conducted using GT-Safety II v1.6. This
safety program is an Excel model that uses failure rates, vehicle configuration, and
weights and sizes to calculate vehicle failure rates and casualty rates. The RASCAL
design was modeled as two stages with the upper stages combined into one stage with
two engines with no engine out capability.
The first stage of the RASCAL design was analyzed using the operations data as
well as the cost data for required flights per year. Aggressive options for abort options
and windows as well as crew escape were taken since the first stage features a high speed
ejection seat, as well as the ability to land while fully loaded. Other factors such as
subsystem failure rates were taken at 1/10 of the ELV data since the fighter operation
