Path: Thermal/Brayton
% Ideal Brayton cycle
Computes the efficiency, mass flow and temperatures. This power plant
has a single compressor and turbine. Both are 100% efficient.
The cycle points are
1 - compressor inlet
2 - compressor outlet
3 - turbine inlet
4 - turbine outlet
Note: t2 = t4 in this ideal cycle.
Type BraytonIdeal for a demo comparing helium, nitrogen and carbon
dioxide.

------
Inputs
------
gamma (1,1) Ratio of specific heats
pR (1,:) Pressure ratio
t3 (1,1) Temperature at end of combustor (deg-K)
cP (1,1) Specific heat constant pressure J/kg deg-K
qR (1,1) Heat input (W)
-------
Outputs
-------
eff (1,1) Thermal efficiency
mDot (1,:) Mass flow (kg/s)
t (4,:) Cycle temperatures (deg-K)
