Maybe as a smaller-scaled back-up design to the Supermarine Type 391?

There's a 3-View of the Supermarine Type 391 in the Morgan and Shacklady book on the Spitfire. The engine seems to be much further forward in relation to the wings on that design so a 'twin' version would be more like a P/F-82 in layout.

I'm going to give Evan's suggestion of using the inner trunnion more thought, seeing as they bolt to the rear side of the firewall/bulkhead/spar on a Spitfire.  Moving them towards the center of the aircraft is more likely an arrangement.  On the Spiteful it's a bit more problematic, the trunnion is on the front side of the bulkhead/spar and the rear of the engine is in the same location on both aircraft.

Perhaps it would progress in a longer, wider, stronger way like the Hurricane/Typhoon/Tempest/P.1030 did, but in a Spiteful sort of way.
Late-model Spitfire or Spiteful with a RR Eagle piston engine?  I know Hawker drew up a Tempest variant with one.

Hawker P.1027 was one version

If jets hadn't made it, would turbo-prop engines ?  just a thought.


My three listed ideas were meant to be independent of each other.

I'd use a bubble top as the basis so I guess it's a Mk.XIVe rather than a PR.XIX for the basis.

Actually Greg, if you give that nose profile the Spiteful works, it'll look pretty good.

Peter Burstow's Spitfire F.22 on floats what-if built from a 1:72nd scale Hawk (Testors) kit uploaded to Modeling Madness. 

Tiny, nice and shiny!  Such a simple little conversion and it looks quite convincing.  Hopefully Peter has more of this to share with us in the future.

Hmm! that looks really nice, I guess a follow on to that would be a Spiteful on floats   :-*

Does anyone have a clear cutaway drawing of a mid to late model Spit?  I'm trying to see where the intake scoop goes inside but I can't figure it out from what's on the net.  I'm probably staring it in the face but just can't see it.  I'm trying to figure out if and where the scoop could be relocated, preferably above the wing as I'm aiming for a float plane version and its current location would cause oodles of issues with water ingestion at all the wrong moments.  Any and help is appreciated as always.

Cliffy: The RW Spitfire floatplanes seemed to do okay with the extended Mk.XI-style air intakes.

I'm not sure if side intakes are an option when using an updraught carburettor. Early Rolls-Royce Kestrels had side intakes for their superchargers. But that changes with the Kestrel XVI (if you look at a late Yugoslav Fury with updraught SU carbs, they have underside supercharger intakes very much like the early Spit).

Perhaps these images will help?

Thanks man!  So I don't need to move nor can I move it apparently...interesting...  Always thought any sort of intake scoops on the undersides of float planes were problematic.  Wonder if it had to do with the height of the floats on the Floaty Spits?  They seem to sit up a lot higher then most other float planes.  Hmmm...

That one drawing of the engine done by hand wow!  Its refreshing to see such a technical drawing done by hand even if it may be from a while ago.

The engine mount would prevent a side intake like what you're proposing.  But you could always give it a downdraft carb', DH Hornets had those because their air intakes were in the wing leading edge and were ducted to the top of the carb'.  You'd need to have the intakes higher than the exhaust stubs though on your Spit.
