The ploughed field camo effect! Looks good, Tony!

if you are calm and collected when all about you are going berserk - you've missed something important!

The tops of the wings have had a second coat of paint.
the undersides have been painted and the reg numbers are now being painted on.



side stringers going on.


i am now printing out the formers for the underwing bomb racks and hope t get building them over the next few days.

but i need to do some 3D design work for Lancaster parts, so it might take longer.

we plod on

well with my new 3d printer all set up and running, i decided to make a start on the underwing bomb holders.
i started by printing out some formers and then glued them to some 3mm depron cores.
the resulting construction is now being covered with more 3mm depron and then the two halves will be joined together.





I need to make the, knock off in case of bad landings,so i shall be making some ply and magnet fittings later.

Thanks

Wonderful stuff Tony, I can’t wait to see how this works out. It has always interested me the way that the bomb panniers were set at such a negative angle of incidence relative to the wing. You would assume that they were designed to have a neutral effect on pitch stability, so I’ve never been able to work out the aerodynamics!

I gave up trying to work out the aerodynamics.
i shall just make them and fit them and hop for the best.
at least if they are removable i can just take them off if they cause problems.

I’m sure they’ll work perfectly well, at that size the aerodynamics should be close to the full-size and they clearly weren’t a problem on that. It’s a fascinating very efficient aeroplane and the performance and load lifting capacity on a plane of that size with just 1,000 hp were incredible.

Made the wing mount from 9mm Balsa, they are cut to match the aerofoil section and have balsa mounts for magnets.
the idea is to have a box on the panniers that will slot over the mount and then it will all be held on with magnets.



they slot on over the wing tubes and will be glued home later when i am happy with everything.


I just need to finish making the panniers now.

we poodle on

I think that the high negative angle of externally carried bombs (and fuel tanks, etc) was to make sure that when it was dropped, it fell away from, rather than sticking to - the carrier.
I think we've all seen that vid where a Skyhawk dropped an external fuel tank, but it flipped up over the top of the wing, collided with the chase plane, and took it's wing off!

Eric, they weren’t dropped. They functioned as fixed bomb bays with opening doors. The plane could be flown without them, but they were a fixture. As originally designed, the slim geodetic structure couldn’t be cut into to create a conventional bomb bay, so the Wellesley was designed from day one to carry the stores in these external bays. Very modern in concept really.

That happened with a dumb bomb as well,despite it being made of concrete

It just dawned on me that I’ve misunderstood Eric. I thought he was suggesting that the bomb panniers were dropped, which they weren’t. Of course he was referring to the process of the bombs leaving the panniers at a negative angle of incidence to ensure that they stayed nose down, so my apologies for misunderstanding what he refers to. It still seems odd though because they’d achieve that by setting the bombs at a negative angle inside the pannier, I just wonder what the thinking was in setting the panniers at such a negative angle.

I suspect the angle of the bomb panniers had more to do with process of loading them than aerodynamics.
At the time the bombs would have been manually loaded so it was important that the panniers were reasonably close to and parallel to the ground when the Wellesley was sitting on its undercarriage. ;)

been plodding on slowly with the build.
got the top of the fuselage covered with silk and hope to get the underside done tomorrow.


then it is just the u/c to sort out.
might get it finished one day. ;)
