% Computes the jet engine efficiency for an ideal turbofan engine. m0, piC or piF can be vectors. Alpha may be zero, i.e pure turbojets can be analyzed. Note that heating value is not an input as it does not impact efficiency. Note that any units for temperature can be used as only their ratio, i.e. tT4/t0, is used internally. Type JetEngineEfficiency for a demo. -------------------------------------------------------------------------- Form: [etaO, etaT, etaP] = IdealJetEngineEfficiency( m0, t0, tT4, piC, gamma, piF, alpha ) -------------------------------------------------------------------------- ------ Inputs ------ m0 (1,:) Mach number t0 (1,1) Inlet temperature tT4 (1,1) Combustor temperature piC (1,:) Compressor pressure ratio gamma (1,1) Ratio of specific heat piF (1,:) Fan pressure ratio alpha (1,1) Bypass ratio ------- Outputs ------- etaO (1,:) Total efficiency etaT (1,:) Thermal efficiency etaP (1,:) Propulsive efficiency --------------------------------------------------------------------------
