Sorry Warbird but subjectively "observed reasoning" without empirical testing will invariably lead a person to incorrect conclusions, particularly when applying “low” speed hydrodynamics with aerodynamics interacting on an object at the boundary layer between the two – it is just not as simple as it “may” seem without applying the correct maths AND actual objective testing any/all theoretical results.
(Slightly off subject but question for Wouter – are you by any chance familiar with the “theory” and the maths that is being applied to research being conducted into “hyper-cavitation” for submerged “missiles” (formally called torpedoes) at present by the military?)
