Summary
This PR fixed the bug reported in #1208. In
preprocess_propulsion(), all theAircraft.Nacellevariables were assumed to allow multi-value. ButAircraft.Nacelle.TOTAL_WETTED_AREAis an exception. See_get_engine_variables()for details. The fix is to exclude it.Two other scalar nacelle variables are
Aircraft.Nacelle.DRAG_FACTORandAircraft.Nacelle.PYLON_DRAG_FACTOR. They are not excluded. In fact, they should be multi-valued. This will be taken care in a separate PR.Related Issues
