% Mixed flow turbofan engine performance profile for p, h and v.
A mixed flow turbofan is one in which the fan and core streams
mix in the same nozzle. This model supports afterburning.
This is the same code as in JetEnginePeformance but designed for
a single input. The outputs are the same as RamjetH2. Only mks units
are supported in this function.
Type MixedFlowTurbofanProfile for a demo
This function calls MixedFlowTurbofan
Note that only ref.h0 need be entered for the atmospheric parameters.
The following are computed from the Standard Atmosphere and AtmGamma
as follows.
q = StdAtm( ref.h0 );
ref.p0 = q.pressure;
ref.a0 = q.speedOfSound;
ref.t0 = q.temperature;
ref.rho = q.density;
ref.gammaC = AtmGamma( ref.t0 );
