In addition, the combustion chamber's inlet temperature increases to very high values, approaching the dissociation limit at some limiting Mach number.

The simplest method uses resistance heaters to vary the inlet temperature, but this approach is slow (cannot change on a cycle-to-cycle basis).

In this case, it can be assumed that the inlet temperature is sea-level standard.

In the event that the variation of inlet temperature is low, the relationship is simplified:

The thermal efficiency (ɳ) increases with increases in the inlet temperature of the working fluid.

This section describes how the compressor was modified for Mach 3.2 flight to handle the aerodynamic effects of high inlet temperature.

In general, the efficiency of the BEE increases with the inlet temperature and the expansion ratio.

In the final stage the brine and the condensate has a temperature near the inlet temperature.

At low reactor power, therefore, the inlet temperature may become dangerously high.

Raising turbine inlet temperature tends to increase thermal efficiency and, therefore, improve fuel efficiency.
