MCGC design parameters

Table 3.3. High-temperature helium MCGC heat exchanger design parameters... 

Table 3.4. Very high-temperature helium MCGC preliminary turbomachinery design parameters...

Table 3.6 shows the turbomachinery parameters for the very high-temperature nitrogen MCGC. Because of the large mass flow rate, only a supersonic blade design is possible, like those used in modem combustion turbines. The tip diameters for turbomachines are much larger than for helium turbines.
