Information
This model extends the EnergySystemBase model and calculates the energy consumption of an electric engine.
This model takes the net thrust (Tnet) through the uThrust port and aircraft total velocity (vtot) from the flightData record propagated from AircraftBase as inputs to solve for the net power generated by the electric engine (Pnet). The net power is divided by the powertrain efficiency parameters propagated from the ElectricEngine model (ηprop and ηmech) to solve for the gross power consumed by the engine (Pgross). In order to calculate the energy consumption (E), the gross power is integrated over time.
