the wingspan is coming in at about 70 feet atm lol iv got to work out how to reduce that without binning the guns in the wings

Apart from stopping it from flying into orbit, no.

Daft? Not in the slightest, the longer the span the better they look, and that goes for ALL aircraft!

i doubt a good trait of an escort fighter is a roll rate you need a sundial to measure

You missed out how GOOD long wings look as well. Or in today's vernacular, 'cool'...........  ;D

Actually span doesn't have as much effect on speed as you might think. There's only a small increase in drag and usually the wing is more efficient just because of it's greater span.

Will it be a single seater, or will it have multiple crew members?

I had a quick go at getting a triple boom Spitfire.

It looks a bit out of proportion, but with 8 20mm it would have plenty of firepower!

Title: Re: triboom long raneg escort spitfire
Post by: Old Wombat on March 12, 2013, 06:48:58 AM
Might I suggest you bring the fuselages closer together & reduce the number of guns between each to 2, rather than 4 (not remove them). Which still gives you 8 x 20mm cannon. Which brings more of the mass of the aircraft closer to the central roll axis.

Also, I'd suggest extending the outer wings slightly & increasing the size of the ailerons, so they move more air. Than should fix your roll rate problem pretty well.

Oh! ... & remove the outer cockpits & spines (selecting a later model Spit might have been a better starting point for that, though).

My cent's worth.

im thinking make the inner wing angle like a corsair?
this would lift the centre fuse for better visibility and keeps the prop off the deck

got 4 cannons in the nose and either 2 or 4 in the inner wings so 6-8 total

Title: Re: triboom long raneg escort spitfire
Post by: perttime on March 17, 2013, 02:38:35 AM
I like the Corsair wing idea better. Do you have - or can you make - straight pieces of wing for the inner sections?

I think keeping the inner sections as short as possible would look cool, as long as the propellers stay away from the pilot pod.

... one of the fuselages could have a rear gunner ...

Which landing gears are you keeping?

inner wings will be as short as possible to keep the mass as close to centre as possible
il have to make the wing by sandwiching plasticard together and sand it all down :(
no gunners
still not 100% settled on gears yet 2 options atm are use the outer stock gears (bit highly stressed though) or have a big wheel go stright up into each outer fuse in the wing root which would be stronger but much more work
im thinking option 2 atm
Title: Re: triboom long raneg escort spitfire
Post by: perttime on March 17, 2013, 03:27:40 AM
Landing gears in the fuselages sounds like a good idea to me, as long as you don't mind the "work". Retracting towards the rear?
Radiators probably have to go in the normal places under the wings, unless there's some space remaining in the fuselages.

Post by: Old Wombat on March 17, 2013, 09:14:09 PM
eatthis, I have an idea for you.

Honestly, more work but possibly a better result &, maybe, an easier beginning to fuselage mounted main gear.

1. Cut vertically fore & aft of the wing-roots to about mid-way up the fuselage.
2. Cut horizontally between these cuts to remove the wing-roots & fuselage section.
3. Remove fuselage section above the wing-roots from the cut-out section(s).
4. Replace wing roots into hole in fuselage(s), lifting to meet upper cut line.
5. Glue in place & shim as necessary to meet fuselage cross-section.

Possible benefits;
a. This will (theoretically speaking) raise the main wing spar to where it can be used for your fuselage-mounted main gears & give you a start on the main gear wells.
b. Also, if you move the existing wing root to the outer edge of the fuselage & only shim the inside, this will give you a good wing root out from the boom fuselages & bring the inner root in flush (hopefully) to the boom so that it doesn't stick out & look out of place when the dihedral wing stub is connected. (You may want to think about angling down the central tub wing-roots, too, so they match the wing stub angle.)

Just a couple of ideas for free.  ;)

iv thought abouth mounting the wings on the top of the outer fuselages instead of the bottom i might not need any anhedral on the inner winner wing at all if i did that
im still sleepy and cant get my head around point b lol what do you mean by it?

b. Also, if you move the existing wing root to the outer edge of the fuselage & only shim the inside, this will give you a good wing root out from the boom fuselages & bring the inner root in flush (hopefully) to the boom so that it doesn't stick out & look out of place when the dihedral wing stub is connected. (You may want to think about angling down the central tub wing-roots, too, so they match the wing stub angle.)

OK, the fuselage at the wing roots is narrower (even if not by much) than the fuselage higher up. By ensuring that the outer cuts line up against each other this will leave you with the full wing root out from the booms & you will only need to shim the inner side of the boom fuselage to the full width. Also, as you have effectively moved the whole wing root outwards there is a smaller section of wing root protruding in from the boom, thus meaning less work blending the new inner wing stub into the boom &, therefore, less drag.

Angles in the wing create drag, the more bends the more drag.

The alternative to what I have given you in the previous post is to line both inner & outer wing root sections with the boom fuselage & have a (relatively) straight wing (this would be my preferred option as there is less work involved). The final result would look a bit more like a P-38 Lightning but, still, quite unique.

Also, just to be a pest, don't forget that the wing roots (as they are are designed to) angle the wings slightly upwards but a bit of sanding should fix most of that & a little angling of the inner wing stubs should be easy enough.

I would draw some pictures of what I'm trying to explain but I'm 4,300 km away from my printer/scanner at the moment &, effectively wont be nearer to it until mid-June.

Perhaps someone else could assist? Please? :unsure:

:cheers:

Guy

PS: Just thinking about this.... You might consider keeping the dihedral of the existing wing roots on the booms & simply angle the central tub wing roots down to match what already exists coming up from the booms! (Much easier!) I'd still raise the wing roots up to about the mid-line of the booms, though.

i can use a flat centre wing now and sit the centre fuse on top of it this will raise it

Is the centre fuselage still the same, for the cockpit? it looks like a bubble-canopy one, from another kit?

Old Wombat: I am willing to draw everything (all versions, not the final choice of eatthis only), but it is hard to understand, sorry.

the front is a drop tank (bloody usefull things for a whiffer) the main fuse is a mk22 spitfire low back with a bubble canopy

basic layout will be this

the elevator will be full width between the outer fuselages im not sure wether to extend it to the outside or not (atm im thinking no)

Eatthis,

You might bear in mind the thrust line of your center engine.  Putting it significantly out of line with the other two engines might make handling the bird a tad... problematic.  Putting the cockpit higher than the boom fuselages though would enhance the visibility from the office though.  While fairing the difference between the lowered engine and the raised cockpit might be more of a challenge it could also add the look of the bird.

The Bratu 220 did fly http://forum.avionslegendaires.net/viewtopic.php?f=3&t=4902 with engines at different heights. Maybe other ones too... What's the problem about them?
Title: Re: triboom long raneg escort spitfire
Post by: Madoc on March 20, 2013, 11:38:14 AM
Tophe,

Different center of thrust lines for the different engines.  The Bratu 220's were all at least aligned on one plane, the vertical in this case.  Having those different thrust lines makes things more complex for matching the center of gravity with the center of lift with the center of thrust.  Trimming the bird out would also be more involved as would any weight changes as the aircraft draws down its fuel or looses its payload, etc.,.  Not impossible, just more difficult.

Eatthis,

Another thing you could, although it might be too late in your build process now, is to put a truly big engine in the center pod.  Something of a whole heckuvalot more horsepower than the other two.  That engine would only be fired up at takeoff / landings and for high speed dashes.  Otherwise, the two wing mounted engines would bear the - more efficient - load of getting the bird from A to B.

That might ease the fairing job.

High speed reminds me of the wing: better use a reinforced wing. Early Spitfires suffered from "aileron reversal" at high speeds: aileron control would twist the wing in the opposite direction, and result in rolling in the wrong direction  :o

Also, I noticed that your wings still have the bumps for the wheels. Will you remove them or install something that explains their presence?
