Supermarine Swift and Attacker

[PR19_Kit]

The problem with leaving the belly tank off a Swift would have meant it would have been limited to operations inside its airfield's perimeter......

Goodness knows why, that ginormous fuselage should have held a super-tanker's worth of fuel!

Wing tip tanks (rather than my so well drawn missiles) would be a solution as would underwing drop tanks.
Or, just invent a much more efficient engine.

[AS.12]

I have the following internal fuel capacities for the Swifts, in Imp gallons, per Pilot's Notes:

Mark	Front	Centre	Rear	Wings	Gunbay	Total
F.Mk.1	113	98	104	150		465
F.Mk.2	112	98	74	176		460
FR.Mk.5	112	98	104	192		506
F.Mk.7	112	104	35	101	196	548

Plus another 220 gallons in the optional belly tank for all Marks.

I don't have the breakdown for the Hunter other than totals:

Mark	Total
F.Mk1/2	337
F.Mk.4/5	414
F.Mk.6	390

So the Swift was actually quite well endowed with fuel, for a British day fighter.  Except for that afterburny thing.

And a draggy fuselage that was a hangover from the bulky centrifugal engine used by the Attacker, one that was also double skinned and vastly over-engineered = heavy, as opposed to the Hunter which was intended for the slimmer Avon from the start.

Exactly, without which it could not take-off.

How much of that over-engineering was actually due to Supermarine toying with the idea of making a carrier aircraft that would belly-land on a rubber deck, and they just over-engineered every prototype just in case one was picked for the role...?

The F1 and F2 managed to take off without afterburner.

Longer wings = more fuel (and a happy Kit)

Take advantage of the bulky fuselage and install a
low bypass turbofan. Increase the size of the intakes
to accomodate increased air-flow, keep reheat, and
make other mods* needed to fill a dedicated low-level
ground attack role.

* including, of course, reduced span for better low-level ride.

Only just...........

Fit a Pegasus, complete with cold air nozzles which would be pointed down and back to generate lift on the take off run.

[jcf]

The engine is mounted so far back in the fuselage that a Pegasus mounting is
questionable.



Pegasus
Type: Twin-spool turbofan
Length: 137 in (3.480 m)
Diameter: 48 in (1.219 m)
Dry weight: 3,960 lb (1,796 kg)

Avon
Type: Turbojet
Length: 126 in (3,200 mm)
Diameter: 35.7 in (907 mm)
Dry weight: 2,890 lb (1,310 kg)

Perhaps a low-bypass version of the Avon?

This is WhiffWorld, just move it forward............

... and add some humongous elephant-ear intakes.
Sounds like a job for ericr.
