Notes

The evaluate function is broken into three sections: Section 1 computes all the forces and moments from propulsors regardless of if they are powered by fuel or an electrochemical energy storage system; Section 2 computees the perfomrance of any converters on the distrution lines, for example, turboshafts, motors, pumps etc; and Section 3 computes the thermal mangement of the system as well as energy consumtion of the powertrain. The state of storage devices such as covnentional fuel tanks, cryogenic tanks and batteries are also updates. Propulsor groups can be “active” or “inactive” to simulate engine out conditions. Energy consumtion from payload and avionics is also modeled

Definitions ‘Propulsor Group’

Any single or group of compoments that work together to provide thrust.
