- integrated_propulsion_jet(jet_engine_weight, engine_W_factor=1.6)[source]#
Calculate the weight of the entire propulsion system
- Assumptions:
The propulsion system is a fixed 60% greater than the dry engine alone. The propulsion system includes the engines, engine exhaust, reverser, starting, controls, lubricating, and fuel systems. The nacelle and pylon weight are also part of this calculation.
