You know there has to be a reason why they don't top-mount engines on very many aircraft. If I had to guess I'd say it's for ease of maintenance (dropping an engine out to repair and replace is simple) and reducing stress on the wing itself. A top mounted engine would present different stresses than a bottom mounted and would probably fatigue faster.

Now on aircraft like fighters the reason the intakes are rarely on the upper-half is due to how air flows over the air frame during high-G maneuvers. The very few that had intakes on the upper surface (I can only think of a single example, the F-117) weren't designed for sustained high-G maneuvering.

About reason:
As first - prevent engine inlet from water - All jet flying boat, that I know, have top-mount engine =)
Second - some STOL aircraft (as Boeing YC-14 or Antonov An-72) have top-mount engine for using Coanda-effect.

I kind of figured about preventing FOD. It's part of why the A-10 has high-mounted engines.

This is well thought out and looks quite elequent :)

Could it occupy the role of the Ekranoplans? :iconcuriosityplz:

Those must be some pretty impressive engines to get something that un-supersonically-aerodynamic past Mach 1... :D

Great work as always

We use thin airfoil, sharp edges, supersonic intakes... Maybe wing must be smaller and increase swept angle, but in general this shape more supersonic,. than subsonic. I think about 1300-1500 kmph of airspeed.
And very powerfull engines (similar aircraft - "Beriev SD MBR" have 4 engines)))

Doesn't look to have much area ruling though, and the stabilising floats would be better if they retracted to the wings inflight... */aerogeek*

I guess that's the beauty of art - laws of physics come second to laws of "looks cool" XD
