Ionizing air requires energy, and the energy consumed might be way more than any gains. Engineers have been doing this stuff for decades and they know a lot more than we do.You've pointed out that over 100mph, the increases in drag lower the efficiency of the ducted fan propulsion.
Would you be willing to consider the idea of trying to ionize airflow inside the duct, in order to reduce drag?
Ionized airflow is more laminar than regular air (diatomic gas) and therefore less turbulent with lower drag characteristics.
Please consider that because duct is surrounding the airflow, it provides better opportunities to ionize that airflow.
There are multiple possible methods of ionization: contact ionization, corona discharge, helicon antenna
