The purpose of this study is to understand how the shape of electrode (the main cupola) may increase significantly the differential hydrostatic pressure thus the lifting thrust applied to the entire ship by the EHD effect. In a previous computer simulation, I have used a simple arcuate electrode, in this case the design is now improved with a tri-arcuate electrode, an annular electrode and also a small spherical electrode placed on the top.
The picture below shows the map of the equipotentials of the E-Field around the entire ship. The cupola is positively charged and the other electrodes negatively charged.

The picture below shows the map of the hydrostatic pressure of the medium such as air or aether, induced by the non-uniform E-Field around the EHD-FS. You may notice that the hydrostatic pressure (which can be compared to aerodynamic pressure) is lower on the upper surface of the tri-arcuate electrode than on the inner surface of the cupola. This can be compared to a conventional airplane wing with the extrados ( upper surface of the wing ) and the intrados ( lower surface of the wing ). This differential pressure is the direct cause of the EHD-FS lift.
The diagram below shows the curve of this hydrostatic pressure above the surface of the cupola along the red line. You may see also the speed vectors (the small blue arrows) of the medium around the EHD-FS.

Compared to an simple cupola, a tri-arcuate electrode seems to give a better lifting efficiency, because the hydrostatic pressure is distributed on all the upper surface of the electrode as you may notice in the diagram below.
