Information
This model extends the EnergySystemBase model and calculates the energy consumption of turbofan and turbojet engines.
This model takes the net thrust (Tnet) through the uThrust port and the thrust-specific fuel consumption (TSFC) parameter propagated from the TurbofanEngine or TurbojetEngine model as inputs. The net thrust is multiplied by the thrust-specific fuel consumption to get the fuel burn rate (ṁfuel), but first the net thrust is constrained to positive values with a limiter to prevent increasing fuel mass when thrust reversers are used. The fuel burn rate is integrated over time to solve for the mass of the consumed fuel (mfuel).
