Facinating technology ... with definite commercial applications ... but there are limitations, especially when considered for military
appications.l
After scanning the aerodynamic theory behind this "ground effect" phenomena ( per
www.se-technology.com... )
It seems that for maximum effeciency these hybrid craft have to be really big ... and even then, they will have problems with deep sea swells beyond
a certain height which is based in part on the rule below
" ...From this theory it follows that induced drag reduces to approximately 50% at a ground clearance of 10% of the wingspan (or equivalent lift
surface)."
So, the single biggest limitation would be wave height clearance in deep sea or rough weather .
It seems that for lakes and coastal applications such a craft could find an operational niche ... or perhaps a very controlled scenario for millitary
exploitation.
