In Reference 9- 67 Garrett Corporation (now part of Honeywell) estimated the failure probabilities of various Brayton system components based on a variety of open cycle engine data. Table 9-15 summarizes the projected failure probabilities for the various Brayton system components. For the recuperator a failure probability rate of 3 x 10 failures/year was estimated. This estimate is based on open cycle systems and is not directly applicable to a recuperator designed for a Prometheus based mission. However, the estimates provide confidence that a reliable recuperator can be constructed for a 15 to 20 year operational life. 

Table 9-17 through Table 9-22 show the results of scaling Honeywell and Hamilton Sundstrand gas coolers to current projected component design specifications. Section 4 provides the closeout non-optimized heat balances that establish these current design parameters. The change in mass is due to increases in required heat transfer by the gas cooler from the primary loop to the heat rejection system, and increased water side temperatures and pressures of the heat rejection system.
