The 'Lifter Simulator for Windows' is a Windows based simulator, with audio/visual interactivity during simple EHD thruster/lifter development. It has been tested with very good results on small lifters powered by up to 30 kV. It also auto-corrects the results for reverse flowing ions generated at the lower part of the thruster, which accelerate towards the upper part. It also manages all your lifter designs in one database. Can load, save and print all results.
Also you may have a lifter try on my (less accurate) JAVA EHD Thruster Solver.
For bigger EHD thruster designs, where reverse ion flow is negligible and for operation at higher voltage than 30 kV, I suggest you use my Autonomous Thruster Calculator.
